  If the average inventory retention period based on history information and the turnover rate of returnable containers can be grasped, it will be useful for analyzing the management state of logistics and extracting issues. However, in order to analyze the management status of logistics related to the inventory of products with expiration dates, etc., and to extract issues, it is necessary to grasp the flow of the logistics status of the inventory. The flow of inventory distribution status is grasped by analyzing the status of inventory at a certain point in time (number, location, number of days of inventory retention, etc.), transition thereof, and the like.

  However, the inventors have found that it is difficult for humans to intuitively grasp the flow of inventory status even if the inventory status at a certain point in time is simply displayed. Specifically, for example, it has been difficult for humans to easily and intuitively grasp the breakdown of the inventory retention period of the inventory, the change in the cycle of the inventory retention period, and the like.

  Therefore, an object of the present invention is to provide an inventory information generation program, an inventory information generation method, an inventory information generation apparatus, an inventory information management system, and an inventory information display apparatus that can easily grasp the flow of inventory status. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the technical scope of the present invention is not limited to these embodiments, but extends to the matters described in the claims and equivalents thereof.

[Logistics management system]
FIG. 1 is a diagram illustrating an example of a physical distribution management system according to the present embodiment. The physical distribution management system in FIG. 1 includes, for example, an inventory management device 1 and an inventory information database 22. The inventory information database 22 is connected via communication with terminals 101 to 104 installed at a plurality of inventory bases such as factories, warehouses, retail stores, and distribution centers. The stock information database 22 receives information on product entry and exit from a terminal at each stock location via a barcode, RFID (Radio Frequency Identification), keyboard, or the like. Based on the information stored in the inventory information database 22, the inventory management device 1 inquires about the inventory at each inventory base, inquires about inventory history information, and the like.

  The distribution management system in FIG. 1 further includes, for example, a receiving / ordering database 200 and a receiving / ordering management apparatus 201. The ordering database 200 stores product order information input from the terminals 101 to 104 of each inventory base connected via communication, for example. Based on the order database 200, the order management apparatus 201 makes an inquiry about orders at each inventory base, an inquiry about order history information, and the like.

  The distribution management system in the embodiment of FIG. 1 includes the ordering / receiving order database 200 and the ordering / ordering management apparatus 201, but is not limited to this example. The physical distribution management system only needs to have the inventory management apparatus 1 and the inventory information database 22 as an inventory information management system.

[Configuration of Inventory Management Device 1]
FIG. 2 is a diagram illustrating an example of the configuration of the inventory management apparatus 1 in the physical distribution management system of FIG. The inventory management device 1 includes, for example, a processor 12, an external interface 11, a display device 13, and a memory 10, and is connected to each other via a bus 14. The memory 10 stores an inventory information generation program 21, and the inventory information generation program 21 cooperates with the processor 12 to realize an inventory information generation process. Further, the inventory management apparatus 1 can access the inventory information database 22 via the external interface 11.

  The inventory information database 22 stores, for example, a history information table of a physical distribution management system. The history information table of the logistics management system is, for example, a table having information such as the identification name of a product to be managed, the inventory location where the product is received, the amount received, the date and time of receipt, the location of delivery, the amount delivered, and the date and time of delivery. . In addition, for example, an inventory ID is assigned to each product group in a product entry / exit unit in the history information table of the physical distribution management system. A specific example of the history information table of the physical distribution management system will be described later.

  Then, the inventory information generation program 21 inputs each warehousing date and each shipping date of a certain product to be analyzed based on the history information table of the physical distribution management system, etc., and the stock quantity of the product is changed every unit time. In addition, an inventory graph in which the inventory retention period is identifiable is generated. The stock retention period indicates a period from the date and time when a certain stock is issued to the date and time of receipt. And each graph produced | generated by the inventory information production | generation program 21 is displayed by the display apparatus 13, for example. Details of the processing of the inventory information generation program 21 will be described later.

[Inventory graph]
Here, an example of the inventory graph will be described. In the present embodiment, the inventory graph represents a change in inventory amount at a predetermined inventory base of a container to be managed, a return container (hereinafter referred to as a target product) containing materials to be transported, and the like. It is a graph. In addition, the target product in the present embodiment is one product that is commonly managed, a return container, or the like. The change in the inventory amount is expressed for each period (hereinafter referred to as unit time) divided by a predetermined time or date as an analysis unit. Here, a general inventory graph and an inventory graph in the present embodiment will be exemplified.

[General inventory graph]
FIG. 3 is a diagram illustrating an example of a general inventory graph GA. In the figure, an inventory graph GA indicating information on the inventory amount of the target product in the target period from January 1 to February 28 is linked with a warehouse graph GD indicating information on warehousing and delivery of the target product. Is displayed. The horizontal axis of the inventory graph GA represents time in units of one day, and the vertical axis represents the inventory amount. In addition, the horizontal axis of the input / output amount graph represents time, and the vertical axis represents the amount of goods received and the amount of inventory. The positive direction on the vertical axis indicates the amount of goods received, and the negative direction indicates the amount of goods left.

  According to the inventory graph GA in FIG. 3, the total inventory amount at each hour does not change beyond 90. In addition, while the inventory amount has changed in a certain cycle from January 4 to February 7, the method of changing the inventory amount has changed since February 8. Thus, according to the general inventory graph GA, the change of the inventory quantity is found. However, depending on the target product, it is necessary to pay attention to the quality of inventory such as freshness, and it is necessary to grasp the inventory retention period of each inventory. According to the inventory graph GA of FIG. 3, the inventory retention period cannot be grasped. For this reason, the quality of inventory cannot be grasped, and it cannot be determined whether or not the operation of warehousing and unloading relating to each inventory is appropriately performed.

[Inventory graph in this embodiment]
FIG. 4 is a diagram illustrating an example of an inventory graph ga generated by the inventory information generation program 21 in the present embodiment. In the same manner as in FIG. 3, FIG. 4 shows an inventory graph ga that shows information on the inventory amount of the target product in the target period from January 1 to February 28, and information on warehousing and delivery of the target product. The entry / exit graph gd is displayed in conjunction with it. The meaning of the horizontal axis and the vertical axis of each graph is the same as that of the graph of FIG.

  In the inventory graph ga of FIG. 4, in addition to the information on the inventory amount, the breakdown of the inventory retention period in the inventory amount is identifiable. For example, the total inventory quantity on January 4 is 60, but the inventory retention period of inventory x1 displayed in a dark pattern is 0 to 10 days, and the inventory retention period of inventory x2 displayed in a thin pattern Is 10 to 20 days. Further, according to the flow of the arrow z4, out of the 60 stocks x1 and x2 received on January 4, the stock x1 disappears from the stock graph ga on January 9. As a result, it can be seen that the stock x1 was shipped on January 9.

  Thus, according to the inventory graph ga in the present embodiment, the inventory retention period of inventory can be identified. In addition, it becomes possible to grasp the breakdown (ratio, amount, etc.) of the inventory retention period of the inventory per unit time (in this example, 1 day) and the time series change of the inventory retention period. As a result, it becomes possible to more intuitively understand the quality of inventory and the flow of physical distribution based on the quality of inventory, and it is possible to analyze whether or not warehousing and delivery are performed appropriately.

  Further, according to the inventory graph ga of FIG. 4, as shown in the inventory x1 and x2 received on January 4, the inventory retention periods of the inventory x1 and x2 received at a time are different (z1). This makes it possible to grasp that the stock received at one time has been delivered in multiple times. Similarly, it is possible to grasp that the stock that has been received in a plurality of times is delivered at a time. Thus, according to the inventory graph ga in the present embodiment, it is possible to easily grasp the unit quantities of entering and leaving a certain stock.

  Further, according to the inventory graph ga of FIG. 4, the inventory x3 of the inventory retention period 0 to 10 received on February 13 is issued before the existing inventory x4 and x5 on February 18. Has been. For this reason, the stock x4 and x5 are not issued, and the stock residence period is extended to 20 to 30 days and 30 to 40 days. This is because the stock x3 with a short stock retention period has been issued earlier than the stocks x4 and x5 with a long stock residence period, and the relationship between receipt and delivery is not a FIFO (First In, First Out) relationship. (Z3). Thus, according to the inventory graph ga in the present embodiment, it is possible to easily grasp that the relationship between the warehousing and the leaving is not a FIFO relationship.

  In addition, in the inventory graph ga of FIG. 4, the inventory is accumulated in descending order from the inventory with the long inventory retention period. For this reason, the stock x3 stacked at the bottom of the stocks x3, x4, and x5 on February 18 does not exist in the graph first, so the relationship between receipt and delivery is not a FIFO relationship. Can be grasped intuitively.

  For example, as shown in the inventory graph ga in FIG. 4, when the inventory graph is accumulated in the longest (or shortest) order of the stock residence period, the cycle of warehousing and unloading in a FIFO relationship continues several times. Each of the stocks classified (or color-coded) according to the stock retention period forms an arrangement pattern such as an oblique stripe pattern as a whole on the graph. Even if they are not in a FIFO relationship, if the cycle of warehousing and leaving is periodically repeated, each inventory that is classified (or color-coded) according to the inventory retention period has some arrangement pattern on the graph. Will come to form. On the other hand, in a situation where the warehousing and unloading cycles are not repeated regularly, an arrangement pattern does not appear on the graph for each inventory that is classified (or color-coded) according to the inventory retention period.

  In this way, the inventory retention period is accumulated according to a certain rule (descending order or ascending order) based on the inventory retention period, so that it is more intuitively grasped whether the warehousing and delivery are performed appropriately. It becomes possible.

  Furthermore, according to the inventory graph ga of FIG. 4, in the period from January 4 to February 2, only the inventory retention period 0 to 10 days and the inventory of 10 to 20 days exist, whereas February 3 In the period after the date, in addition to the inventory retention period of 0 to 10 days and the inventory of 10 to 20 days, the inventory retention period of 20 to 30 days and the inventory of 30 to 40 days exist (z2). This means that the operation of entering and leaving has changed. For this reason, according to the inventory graph ga in the present embodiment, it is possible to grasp the change in operation of entering and leaving.

  In this way, according to the inventory graph ga in the present embodiment, the inventory retention period of each inventory can be grasped, so that the time series of the inventory retention period and the unit quantity of receipt and delivery of each inventory are changed. It becomes possible to grasp about intuitively. For this reason, it is possible to determine whether or not warehousing and delivery corresponding to the stock are properly performed, and it is possible to intuitively understand the change in operation. Thereby, analysis about the flow of inventory status and extraction of a subject are performed efficiently.

  In FIG. 4, in addition to the inventory graph ga, an entry / exit graph gd corresponding to the inventory graph ga may be displayed. In the loading / unloading graph gd, the corresponding stock and the stock dwelling period are represented identically for loading and unloading. Specifically, the inventory x1 on January 4 in the inventory graph ga corresponds to the receipt on January 4 and the storage on January 9th. For this reason, the stock x1 on January 4 in the stock graph ga, the stock on January 4 and the stock on January 9 are represented with the same stock retention period so that they can be identified. As described above, the warehousing date and the evacuation date corresponding to the stock can be easily associated based on the stock residence period. As a result, each graph can be traced in time series based on the inventory retention period, and the inventory flow can be intuitively grasped. Thereby, analysis in inventory management and problem extraction are performed more efficiently.

[First Embodiment]
Next, a process for generating the inventory graph ga shown in FIG. 4 will be described.

[Flow of inventory graph generation processing]
FIG. 5 is a flowchart for explaining the flow of the inventory graph generation process by the inventory information generation program 21 in the present embodiment. The inventory information generation program 21 according to the present embodiment inputs a warehousing date and a warehousing date for a plurality of target products, and stocks by target stock retention period for each unit time to be analyzed. Is calculated. Then, the inventory information generation program 21 generates an inventory graph in which the calculated inventory amount of the target product is represented according to the descending order or ascending order of the inventory retention period for each unit time so that the inventory retention period can be identified.

  First, the inventory information generation program 21 extracts the storage date and time of inventory at the inventory location to be analyzed (S11). Specifically, the inventory information generation program 21 stores the inventory ID having the receipt information for the inventory location to be analyzed in the analysis target period from the distribution management system history information table having the information of the plurality of inventory locations, and the date and time of receipt. To extract. Note that information may be further filtered with respect to the inventory ID to be extracted by information such as the product name to be analyzed.

  Subsequently, the stock information generation program 21 extracts the stock issue date and time corresponding to the extracted stock ID (S12). The inventory information generation program 21 determines the movement of the inventory and the movement destination thereof from the physical distribution management system history information table, and determines the inventory ID having the delivery information from the stock location to be analyzed in the analysis target period, and the delivery date and time. Extract.

  Next, the inventory information generation program 21 calculates an inventory retention period for each inventory (S13). Specifically, the inventory information generation program 21 subtracts the warehousing date and time from the extracted delivery date and time for the inventory ID having the warehousing information to the stock location to be analyzed extracted in steps S11 and S12, and sets the stock residence period. calculate. Note that the inventory information generation program 21 calculates a period from the receipt date and time to the reference date as an unissued residence period for stocks that do not have a delivery date, that is, unstocked stock. The reference date is, for example, the final date and time in the analysis target period. Thereby, based on the physical distribution management system history information table, an entry / exit situation table having information on the stock retention period is generated for each stock.

  Regarding the calculation of the inventory retention period, the user can define the inventory retention period, such as whether the delivery date, the receipt date itself is added to the inventory retention period, and whether only one of them is added to the inventory retention period. May be changed by

  Subsequently, the inventory information generation program 21 adds an inventory retention period and an unreserved retention period as information from the warehousing date and time to the warehousing date for each inventory in the warehousing status table (S14). Specifically, the inventory information generation program 21 assigns an inventory stay period and an unissued stay period to each date and time from the corresponding receipt date to the delivery date for each inventory ID in the entry / exit status table. Generate a period table.

  Here, specific examples of input and generated tables in the processes of steps S11 to S14 will be described. First, a specific example of a physical distribution management system history information table that is input to the inventory information generation program 21 will be described.

[Specific example of logistics management system history information table]
FIG. 6 is a diagram illustrating an example of the physical distribution management system history information table T1. The physical distribution management system history information table T1 in the same figure is the history information of the entry / exit of the product A and the product B, and has the history information of the entry / exit whose stock location is Tokyo or Osaka in the date unit. Further, each stock in the physical distribution management system history information table T1 is provided with information on a stock ID and a stock quantity for each product group to be moved.

  The inventory information generation program 21 extracts, for example, the inventory ID having the warehousing information for Tokyo as the inventory location to be analyzed and the warehousing date / time from the distribution management system history information table T1 (S11). Accordingly, inventory ID: 1000 / receipt date: January 1, inventory ID: 1010 / receipt date: January 3, inventory ID: 1020 / receipt date: January 5, inventory ID: 1030 / receipt date: Information on January 5th, Inventory ID: 1040 / Receiving date: January 10th is extracted. Subsequently, the stock information generation program 21 extracts the stock issue date and time corresponding to the extracted stock ID (S12). Accordingly, inventory ID: 1000 / issue date: January 6, inventory ID: 1010 / issue date: January 8, inventory ID: 1020 / issue date: January 15, inventory ID: 1030 / issue date: Undecided, Inventory ID: 1040 / Shipping date: Undecided information is extracted.

  Subsequently, the inventory information generation program 21 calculates an inventory retention period for each inventory (S13). In this example, the reference date is, for example, January 15. Thus, inventory ID: 1000 / inventory residence period: 5 days, inventory ID: 1010 / inventory residence period: 5 days, inventory ID: 1020 / inventory residence period: 10 days, inventory ID: 1030 / unissued residence period: 10 The information of day (unissued), inventory ID: 1040 / unissued residence period: 5 days (unissued) is extracted. Thereby, the loading / unloading situation table T2 is generated.

[Specific example of entry / exit status table T2]
FIG. 7 is a diagram illustrating an example of a loading / unloading situation table T2 generated based on the physical distribution management system history information table T1 of FIG. 6 and an example of an inventory retention period table T3. The entry / exit situation table T2 displayed in the upper part of the figure is a table generated by the processes of steps S11 to S13 in the flowchart of FIG.

  In the entry / exit status table T2 in FIG. 7, the row indicates the inventory ID, and the column indicates the date and time. The entry / exit status table T2 has, for each inventory ID, an entry / exit status corresponding to the date and an inventory retention period on the delivery date. In addition, the entry / exit status table T2 has an unissued retention period on the reference date for an unissued inventory. In this example, the entry / exit situation table T2 has an entry / exit situation in which the inventory location of the product A is Tokyo.

  According to the distribution management system history information table T1 of FIG. 6, the stock ID: 1000 having the stock information to Tokyo has a stock date of January 1, a stock date of January 6, and a stock retention period of 5 days. It is. For this reason, the entry / exit status table T2 includes information indicating that the inventory was received on January 1 for the inventory ID: 1000, and information corresponding to the inventory retention period of 5 days corresponding to the information indicating that the inventory was issued on January 6. Have. Similarly, the stock ID: 1030 having the stock information to Tokyo has a stock date of January 5, a stock date is undetermined, and a stock stock stay period based on the reference date is 10 days. For this reason, the entry / exit status table T2 includes the information indicating that the inventory ID: 1030 was received on January 5th, the information indicating that the inventory date is January 15th, which is the reference date, and the unshipped residence period. Has 10 days of information.

  In step S14, for each inventory ID included in the entry / exit status table T2, an inventory retention period and an unexited residence period are assigned to each date and time from the corresponding entry date / time to the delivery date / time, and an inventory retention period table is generated. Is done.

[Specific example of inventory retention period table T3]
In the central part of FIG. 7, an example of an inventory retention period table T3 generated by the process of step S14 is represented based on the entry / exit situation table T2. In the inventory retention period table T3 in the figure, the rows indicate inventory IDs, and the columns indicate the date and time. The inventory retention period table T3 has information on the inventory retention period or the unreserved retention period for each date between the delivery date and the receipt date for each inventory ID.

  In this example, the entry / exit situation table T2 has information about the inventory ID: 1000, the entry date: January 1, the exit date: January 6, and the inventory retention period of 5 days. For this reason, the inventory residence period table T3 has information on the inventory residence period of 5 days on each date from the entry date: January 1 to the delivery date: January 6 for the inventory ID: 1000. Similarly, the inventory retention period table T3 has information on the undelivered retention period of 10 days on each date from the entry date: January 5 to the reference date: January 15 for the inventory ID: 1030.

  The inventory retention period table T4 displayed at the bottom of FIG. 7 is another form of the inventory retention period table T4. The inventory retention period table T4 has information on the inventory retention period or the unreserved retention period for each inventory ID in addition to the information on the receipt date and the delivery date. The inventory residence period table may be in any form.

[Continuation of inventory graph generation processing]
Returning to the flowchart of FIG. 5, the inventory information generation program 21 subsequently calculates the inventory amount for each date and time for the inventory retention period and for the unissued retention period (S15). Specifically, the inventory information generation program 21 detects the inventory having the same inventory retention period in the date and time unit (column direction) in the inventory retention period table T3 in FIG. 7, and sets the detected inventory ID for each inventory retention period. Calculate the sum of the corresponding inventory quantities. Thereby, the inventory quantity table T5 for each inventory residence period is generated.

  Subsequently, the inventory information generation program 21 displays the stock quantity for each stock residence period and each unreleased residence period by a stacked graph according to the descending order or the ascending order by the inventory residence period and the unissued residence period (S16). ). The inventory information generation program 21 displays a graph displaying the inventory amount for each date so that the inventory retention period and the unissued retention period can be identified based on the inventory amount table for each inventory retention period generated by the process of step S15. Generate. In this example, in descending order, stocks with a long stock residence period are stacked above, and in ascending order, stocks with a long stock residence period are stacked below.

[Specific example of inventory quantity table by inventory retention period]
FIG. 8 is a diagram illustrating an example of an inventory amount table T5 for each inventory retention period generated based on the inventory retention period table T3 of FIG. In the inventory amount table T5 for each inventory retention period, the rows indicate the inventory retention periods, the columns indicate the date and time, and each date has information on the inventory amount for each inventory retention period and unissued residence period.

  Specifically, in the inventory retention period table T3 in FIG. 7, the inventory remaining on January 1 is only the inventory ID: 1000 and the inventory amount is 10. For this reason, the inventory amount table T5 for each inventory retention period in FIG. 8 has information that the inventory for the inventory retention period of 5 days (5 days of retention) is 10 for January 1.

  In addition, in the inventory retention period table T3 of FIG. 7, the inventory that remains on January 5 is inventory ID: 1000, inventory ID: 1010, inventory ID: 1020, and inventory ID: 1030. The stock retention period of the stock ID: 1000 and the stock ID: 1010 is 5 days, and the total stock quantity of each stock ID is 30. Further, the stock ID: 1020 has a stock retention period of 10 days and the stock quantity is 20, and the stock with the stock ID: 1030 has not been issued yet. The unissued residence period is 10 days and the stock quantity is 20. Therefore, in the inventory amount table T5 for each inventory retention period in FIG. 8, the inventory for the inventory retention period of 5 days (retention 5 days) is 30 and the inventory for the inventory retention period of 10 days (retention 10 days) for January 5th. , 20 and the inventory of the unshipped residence period of 10 days (undecided 10 days) is 20.

[Specific example of inventory graph]
FIG. 9 is an example of an inventory graph ga-1 generated based on the inventory amount table T5 for each inventory retention period in FIG. The horizontal axis of the inventory graph ga-1 in the figure is the date and time, the vertical axis is the inventory quantity, and the inventory quantity is expressed so that the inventory retention period can be identified. Further, in this example, the stock residence periods are stacked in descending order. Further, the unshipped residence period is also stacked in the descending order of the unissued residence period on the inventory residence period.

  As described above, based on the distribution management system history information table T1 shown in FIG. 6, the stock residence period in the stock quantity by date can be identified based on the information on the entry / exit date of the product A entered / exited in Tokyo. An inventory graph ga-1 is generated. This makes it possible to determine the inventory retention period that indicates the quality of each inventory, and the breakdown (ratio, quantity, etc.) of inventory retention period for each unit time and the unit quantity of loading / unloading are based on the inventory retention period. It becomes possible to grasp intuitively. In addition, it is possible to easily grasp whether or not there is a change in the operation of the warehouse in the target period. This makes it possible to intuitively grasp the status of warehousing and delivery related to each stock based on the inventory retention period, and efficiently analyzing whether or not warehousing and delivery are performed appropriately. to enable.

  In addition, in the inventory graph ga-1 in the present embodiment, each inventory is stacked in descending order or ascending order of the inventory retention period. This makes it possible to more intuitively grasp whether or not the stock having the longest stock retention period has been delivered when the stock changes due to the delivery. As a result, it is possible to intuitively determine whether or not warehousing and delivery corresponding to the stock are properly performed, so that distribution management analysis and problem extraction are effectively performed.

  In addition, according to the inventory graph ga-1 in the present embodiment, for an inventory whose shipping date is not yet determined, the unshipped residence period calculated based on the reference date is also displayed in an identifiable manner. This makes it possible to identify the quality of the inventory based on the unissued residence period starting from the reference date even if the inventory delivery date is undetermined.

  In the present embodiment, the unit time that is the unit of the horizontal axis of the inventory graph ga-1 is one day, but is not limited to this example. The unit time may be changed to a time unit, a week unit, or the like according to the inventory fluctuation speed and the movement speed. Along with this, the time unit of each table that is the basis of the inventory graph ga-1 is also changed.

[Another form of inventory graph 1]
FIG. 10 is a diagram illustrating an example of another form of the inventory graph ga-2. The inventory graph ga-2 in FIG. 9 indicates that the inventory retention period is undetermined instead of the unissued residence period for the unissued inventory for which the delivery date has not been confirmed, with respect to the inventory graph ga-1 in FIG. Information.

  According to the inventory amount table T5 for each inventory retention period in FIG. 8, the inventory amount for the inventory retention period of 5 days for which the delivery date is fixed is 30 for the inventory on January 5, and the inventory for the inventory retention period of 10 days is 30. The amount is 20. In addition, the stock quantity of unreleased stock is 20. For this reason, for the inventory on January 5 in the inventory graph ga-1 of FIG. 10, in addition to the respective inventory quantities for the inventory retention period of 5 days and the inventory retention period of 10 days, the inventory 20 with an undecided delivery date is undecided. Expressed as inventory. This makes it possible to intuitively determine the stock retention period of each stock per unit time, and enables clear discrimination between stocks for which the delivery date is confirmed and unconfirmed stocks.

[Flow of processing to generate another form of inventory graph]
FIG. 11 is a flowchart for explaining the processing flow of the inventory information generation program 21 that generates another form of the inventory graph ga-2. In the flowchart of FIG. 5, the processes in steps S11 and S12 are the same as those in the flowchart of FIG.

  In this example, the inventory information generation program 21 calculates the inventory retention period for each inventory, but sets the inventory retention period as undecided for the unreleased inventory (S23). Next, the inventory information generation program 21 gives an inventory retention period as information from the entry date and time to the delivery date and time for each inventory, but gives information that the inventory retention period is undetermined for unstocked inventory (S24). Subsequently, the inventory information generation program 21 calculates an inventory quantity for which the inventory retention period is undetermined for each date and time of the inventory retention period (S25). Subsequently, the inventory information generation program 21 displays each stock retention period and the inventory amount whose inventory retention period is undetermined by a stacked graph for each unit time in the analysis target period (S26). When the stock residence period is stacked in descending order, for example, the inventory amount whose stock residence period is undetermined is stacked at the top.

[Another form of inventory graph 2]
FIG. 12 is a diagram illustrating an example of another form of the inventory graph ga-3. The stock graph ga-3 in the same figure does not display the unissued stock for which the delivery date has not been finalized compared to the stock graph ga-1 in FIG.

  As described above, according to the inventory amount table T5 for each inventory retention period in FIG. 8, the inventory amount for the inventory retention period of 5 days for which the delivery date is fixed is 30 for the inventory on January 5, and the inventory retention period The stock for 10 days is 20. In addition, the stock quantity of the stock whose delivery date is not fixed is 20. For this reason, only the inventory with the inventory retention period of 5 days and the inventory retention period of 10 days is displayed for the inventory on January 5 in the inventory graph ga-3 of FIG. As a result, since only the inventory for which the delivery date is confirmed is displayed for each inventory residence period, it is possible to perform reliable analysis based on the confirmed inventory information.

[Flow of processing to generate another form of inventory graph]
FIG. 13 is a flowchart for explaining the processing flow of the inventory information generation program 21 that generates another form of the inventory graph ga-3. In the flowchart of FIG. 5, the processes in steps S11 and S12 are the same as those in the flowchart of FIG. Moreover, the process of process S23, S24 is the same as that of the flowchart figure of FIG.

  In this example, when information about the inventory retention period and the inventory retention period undetermined information is given as information from the entry date and time to the delivery date and time (S24), the inventory information generation program 21 targets the inventory for which the delivery date is fixed. Then, the inventory quantity for each inventory retention period at each date and time is calculated (S35). Subsequently, the inventory information generation program 21 displays the inventory quantity for each inventory residence period as a stacked graph for each unit time in the period to be analyzed (S36). At this time, the unissued inventory is not displayed on the graph.

  As described above, according to the inventory information generation program in the present embodiment, the inventory graph that can identify the inventory retention period in the inventory quantity per unit time based on the information on the receipt date and the delivery date of the target product Is generated. In addition, in the inventory graph, the inventory for which the delivery date is not fixed may or may not be displayed as the undeparted residence period starting from the reference date, or the information that the inventory residence period is undetermined. . Moreover, you may make it selectable by the user about the presence or absence of the display of the stock which has not decided the delivery date.

  As a result, it is possible to intuitively grasp the amount and ratio of each stock having different stock residence periods and changes in time series. For this reason, it becomes possible to grasp the change in the operation of the product in and out of the product, and it is possible to grasp the order of consumption, the amount of consumption, and the like of the material transported in the return container and the change. In this way, the flow of inventory status can be intuitively grasped based on the inventory retention period of inventory.

  In addition, in the inventory graph in this embodiment, each stock is stacked in descending order or ascending order of the inventory retention period, so whether or not the inventory with the longest inventory retention period has been issued when the inventory changes due to issue. Can be grasped intuitively. As a result, it is possible to determine whether the delivery order of products, materials transported in returnable containers, and the like is appropriate, and the analysis of the inventory status flow and the extraction of issues can be performed efficiently.

  In this embodiment, the stock residence period is set to a 10-day range such as 0 to 10 days and 10 to 20 days. However, it is not limited to this example. The stock residence period may be set in units of one day or several hours, or may be set in units of a predetermined period in which a change occurs in stock. In addition, the range of the stock residence period may be arbitrarily selected by the user.

  Moreover, in each graph in the present embodiment, the stock residence period and the unissued residence period are represented by different patterns such as halftone dots and diagonal lines. However, it is not limited to this example. The inventory residence period and the unissued residence period may be displayed so as to be identifiable by different colors, or the inventory residence period and the unissued residence period are displayed in a graph so as to be identifiable. Also good.

[Second Embodiment]
In the second embodiment, in addition to the inventory graph, the inventory information generation program 21 generates an warehousing graph and an evacuation graph in which the inventory residence period is identifiable in the same manner as the inventory graph. The inventory retention period is expressed in the same way between the graphs, so that the user can intuitively associate the receipt in the receipt graph corresponding to a certain inventory in the inventory graph and the delivery in the exit graph based on the inventory retention period. Can do. Thus, the user can easily grasp the inventory flow based on the inventory retention period, and can more efficiently analyze the inventory flow and extract the issues.

[Specific examples of each graph]
FIG. 14 is a diagram illustrating a specific example of each graph generated in the second embodiment. In the figure, in addition to the inventory graph ga-1 generated in the first embodiment, a warehousing graph gb-1 and an evacuation graph gc-1 in which the time on the horizontal axis is linked are displayed. Each warehousing in the warehousing graph gb-1 and each warehousing in the warehousing graph gc-1 are given the same inventory retention period as the corresponding inventory in the inventory graph ga-1.

  In the graph of FIG. 14, for example, for the inventory x11 of the inventory retention period 10 to 20 in the inventory graph ga-1, January 5th in the receipt graph gb-1 displayed as the same inventory retention period as the inventory x11. It is easily associated with the entry x12 and the delivery 15 x13 of January 15 in the delivery graph gc-1. In addition, for example, the warehousing x12 and x14 on January 5 in the warehousing graph gb-1 include a warehousing x12 for an inventory retention period of 10 to 20 days and a warehousing x14 for an unissued retention period of 10 days. As a result, it is possible to easily grasp that products received at one time on January 5 are delivered two or more times.

  As described above, according to the second embodiment, in addition to the stock graph ga-1, the stock graph gb-1 and the stock graph gc-1 in which the stock residence period is commonly expressed are generated. The user can intuitively trace the storage date and the storage date of the inventory, and can intuitively grasp the unit quantity of the storage / extraction in the inventory. Therefore, the inventory flow can be easily grasped based on the inventory retention period of the inventory, and analysis and problem extraction are performed more efficiently.

  Next, the flow of graph generation processing in the inventory information generation program 21 in the second embodiment will be described.

[Flow of each graph generation process]
FIG. 15 is a flowchart for explaining the processing flow of the inventory information generation program 21 in the second embodiment. In addition to the inventory graph generation process in the first embodiment, the inventory information generation program 21 in the present embodiment can further identify the amount of warehousing in the same manner as the inventory retention period of the corresponding inventory. A warehousing graph is generated in which the warehousing graph and the warehousing amount that are represented are the same as the stock retention period of the corresponding stock and are identifiable.

  The processes from step S11 to S15 in the flowchart in FIG. 15 are the same as those in the flowchart in the first embodiment in FIG. In the second embodiment, the inventory information generation program 21 calculates the total inventory quantity for each stock retention period for each date and time, and for each stock retention period for each storage date and time after calculating the total inventory amount for each unreleased residence period (S15). The amount of goods received according to the unissued residence period is calculated (S46).

  Specifically, the inventory information generation program 21 detects, in the inventory residence period table T3 shown in FIG. 7, for each date and time in the column direction, an inventory in which the date and time is the warehousing date and the inventory residence period is the same. Then, the sum is calculated as the amount of goods received. In the same way, the total sum of warehousing amounts is calculated for stocks with the same unshipped residence period. Thereby, the warehousing amount table for each stock residence period is generated.

  Subsequently, the inventory information generation program 21 calculates the amount of delivery for each stock retention period and each unreleased residence period at each delivery date (S47). Specifically, the inventory information generation program 21 detects, in the inventory retention period table T3 shown in FIG. 7, for each date and time in the column direction, the inventory that has the same inventory retention period as the date of issue. Then, the sum is calculated as the output amount. As a result, a delivery amount table for each stock residence period is generated. As described above, as a result of the processes in steps S46 and S47, a storage amount table for each stock residence period and a delivery amount table for each stock residence period are generated.

[Incoming quantity table and outgoing quantity table for each stock period]
FIG. 16 is a diagram illustrating an example of a warehousing amount table T6 for each inventory retention period and a delivery amount table T7 for each inventory retention period. In the figure, a warehousing amount table T6 for each inventory residence period generated in the process of step S46 and a delivery amount table T7 for each inventory residence period generated in the process of step S47 are displayed.

  The rows in the warehousing amount table T6 for each stock staying period indicate the stock staying period and the unshipped staying period, the columns indicate the date and time, and each date and time has information on the stocking amount for each stock staying period. Specifically, the stock amount table T6 for each stock residence period has information that the stock for the stock residence period of 5 days (5 days of residence) has been received for January 1, and has been received on January 3rd. The inventory of the inventory retention period of 5 days (5 days of retention) is 10, the inventory of January 5th, the inventory of the inventory retention period of 10 days (10 days of retention), and the unoccupied storage period of 10 days (undecided 10 days) For inventory 20 and January 10, there is information indicating that 20 stocks for 10 days (undecided 5 days) have been received.

  In addition, the rows in the outgoing quantity table T7 for each stock residence period indicate the stock residence period and the unreleased residence period, the columns indicate the date and time, and the information on the outgoing quantity for each stock residence period is provided for each date and time. Specifically, the stock amount table T7 for each stock stay period has information that the stock of the stock stay period of 5 days (5 days of stay) has been delivered for January 6, and that the stock has been delivered. , The stock has a stock retention period of 5 days (5 days of residence) and has information indicating that the stock has been delivered.

  In the flowchart of FIG. 15, the inventory information generation program 21 then adds the inventory retention period in the period to be analyzed, the warehousing amount for each unreserved residence period, and the delivery in addition to the inventory graph in the first embodiment. The amount is displayed in a stacked graph in the descending order or the ascending order of the inventory retention period, the unissued retention period, in synchronization with time (S48).

  Specifically, the inventory information generation program 21 is based on the inventory quantity table T5 for each inventory residence period in FIG. 8, the warehousing quantity table T6 for each inventory residence period in FIG. 16, and the delivery quantity table T7 for each inventory residence period. Create a stock quantity fluctuation graph, a stock quantity fluctuation chart, and a stock quantity fluctuation graph that make it possible to identify the stock stay period and the unissued stay period. The inventory information generation program 21 displays each graph with the time on the horizontal axis synchronized. The stacking order of the stock residence period in the warehousing graph and the warehousing graph is set in common with the stock graph.

  Thereby, based on the physical distribution management system history information table T1 shown in FIG. 6, the inventory graph in which the inventory amount is calculated for each day, and the warehousing in which the inventory graph and the inventory retention period can be commonly identified. A graph and an outgoing graph are generated. In the present embodiment, a warehousing graph and a warehousing graph are generated, but only a warehousing graph may be generated. Since the inventory graph and the warehousing graph are generated in conjunction with each other, the relationship between the inventory and the warehousing can be intuitively grasped based on the inventory retention period.

  As described above, according to the inventory information generation program in the present embodiment, the inventory graph that can identify the inventory retention period in the inventory quantity per unit time based on the information on the receipt date and the delivery date of the target product In addition to the above, each graph is generated in which the storage amount and / or the output amount per unit time are represented so that the stock residence period of the corresponding stock can be identified.

  This makes it possible to determine the inventory retention period that indicates the quality of each inventory, and the breakdown (ratio, amount, etc.) of the inventory retention period of the inventory per unit time and the amount of storage and retrieval are intuitive based on the inventory retention period. Can be grasped. In addition, it is possible to easily grasp whether or not there is a change in the operation of the warehouse in the target period. As described above, since the flow of the inventory status can be intuitively grasped based on the inventory retention period of the inventory, the inventory status analysis and the problem extraction are performed more efficiently. In addition, by stacking each inventory in descending order or ascending order of inventory retention period, it is possible to intuitively determine whether the inventory has been delivered from the inventory with the longest inventory retention period, and goods are received and delivered appropriately. It is also possible to easily determine whether or not there is.

  In addition, the receipt and delivery corresponding to inventory in each graph are expressed with the same inventory retention period, so that the flow of inventory status based on receipt and delivery can be more easily grasped, and the receipt of inventory. Also, it is possible to easily grasp the unit amount of the delivery. Thereby, the analysis of the flow of the inventory status and the extraction of the issues are performed more effectively.

[Another form of the receipt graph]

The rows in the storage / retrieval amount table T8 for each stock retention period indicate the stock retention period and the unreserved storage retention period, the columns indicate the date and time, and have information on the storage amount for each stock retention period for each date and time. Moreover, in the entering / exiting amount table T8 for each stock residence period, the leaving amount is held as a negative value. Specifically, the stock amount table T8 for each stock residence period has information indicating that 10 stocks in the stock residence period 5 are received as 10 on January 1, etc., and is −10 on January 6. As information indicating that 10 stocks have been delivered for 5 days.

[Another form of the entry / exit graph 1]
FIG. 21 is a diagram illustrating an example of another form of the inventory graph and the entry / exit graph generated in the third embodiment. The inventory graph ga-2 and the entry / exit graph gd-2 in the figure have information indicating that the inventory retention period is undetermined with respect to the unreleased inventory for which the delivery date is not fixed. For this reason, the inventory graph ga-2 and the receipt / exit graph gd-2 have information on the inventory dwell period undetermined for the stock x21 and the receipt x22 that have not been delivered.

[Another form of the entry / exit graph 2]
FIG. 22 is a diagram illustrating an example of another form of the inventory graph and the entry / exit graph generated in the third embodiment. In the inventory graph ga-3 and the entry / exit graph gd-3 in the same figure, only the inventory and the receipt with the confirmed delivery date are displayed. For this reason, regarding the inventory on January 5 in the inventory graph ga-3, the inventory for which the delivery date is not fixed (x21 in FIG. 21) and the receipt in the entry / exit graph gd-3 (x22 in FIG. 21) are not displayed.

  As described above, according to the inventory information generation program in the present embodiment, the inventory graph that can identify the inventory retention period in the inventory quantity per unit time based on the information on the receipt date and the delivery date of the target product In addition, for each unit time, a loading / unloading graph is generated that shows that the stock retention period of the corresponding inventory can be identified, with the loading / unloading amount as the loading amount in the positive direction and the loading amount as the negative direction. The

  This makes it possible to determine the inventory retention period that indicates the quality of each inventory, and the breakdown (ratio, quantity, etc.) of inventory retention period for each unit time and the unit quantity of loading / unloading are based on the inventory retention period. It becomes possible to grasp intuitively. In addition, it is possible to easily grasp whether or not there is a change in the operation of the warehouse in the target period. As described above, since the flow of the inventory status can be intuitively grasped based on the inventory retention period of the inventory, the inventory status analysis and the problem extraction are performed more efficiently. In addition, by stacking each inventory in descending order or ascending order of inventory retention period, it is possible to intuitively determine whether the inventory has been delivered from the inventory with the longest inventory retention period, and goods are received and delivered appropriately. It is also possible to easily determine whether or not there is.

  In addition, in each graph, the warehousing and delivery corresponding to the inventory is expressed with the positive direction as the warehousing and the negative direction as the warehousing, and the stock retention period is the same. Can be grasped more easily. Thereby, the analysis of the flow of the inventory status and the extraction of the problem are performed more effectively.
