Description

  The present invention relates to a vehicle parts inventory management system and method for holding each of the above parts with an appropriate inventory quantity in a future predetermined period for a plurality of bases that own and manage parts for vehicles such as automobiles. It is.

  Generally, the inventory base for vehicle parts is provided so as to form a plurality of layers of a lower layer side and an upper layer side having jurisdiction over the lower layer side. In other words, there is a sales base that sells parts directly to customers as the lowest level base, and the bases that manage the sales bases by prefecture and supply parts to the sales bases (logistics bases, etc.) As a base, there is a parts warehouse that has jurisdiction over the logistics bases and supplies parts to the logistics bases, etc., as the top-tier base, and is hierarchically arranged from these top-tier bases to the bottom-tier bases. Yes.

As an inventory replenishment management system for managing inventory / replenishment of parts at each of the above-mentioned locations, for example, the one disclosed in Patent Document 1 is known. The inventory replenishment management system includes a management server, a sales base terminal provided at a sales base, and a physical distribution base terminal provided at the physical distribution base. The management server calculates the target stock quantity at the sales base based on the information on the order of parts received from the sales base terminal, and replenishes the parts at the sales base based on the new order quantity and the fluctuation amount of the target stock quantity. The amount is calculated, and the distribution base is instructed to replenish the sales base with parts for the replenishment amount. The management server also calculates the excess inventory amount at the sales base based on the difference between the target inventory amount at the sales base and the actual available inventory amount, and collects the parts corresponding to the excess inventory amount at the distribution base. Instruct. As a result, the sales base can manage an appropriate type and number of parts even though it has limited space, and can immediately respond to parts orders from customers. .
JP 2002-342431 A

  By the way, when a vehicle breaks down, it cannot be easily replaced. Therefore, it is usually handled by replacing a failed part. If this replacement part cannot be obtained immediately, the customer will be kept waiting for a long time in a state where the vehicle cannot be used, and the serviceability for the customer will be greatly reduced. In particular, when a part is ordered from an overseas parts manufacturer, the customer has to wait for a longer period of time. For this reason, the bases supplying and selling parts calculate the future demand forecast from the past orders received at each base, as in the above conventional example, so that customers do not wait for a long time. Because it is not possible to replenish all of them in advance due to various circumstances such as inventory space, if some of them are replenished as supplementary parts and more orders are received, It will be arranged as an emergency part. In other words, the parts ordered by the sales base to the higher bases are supplement parts that are replenished based on the demand forecast value of the parts, and the emergency parts that are urgently needed because there is no stock despite orders from customers. It is included. And from the viewpoints of responding promptly to customer orders and the limited amount of inventory at distribution bases, when a sales base orders parts from a higher base, the parts It is desirable to determine whether the item is a supplemental part or an emergency part and change the ordering destination accordingly.

  However, the above-described inventory replenishment management system uniformly places orders with respect to distribution bases without distinguishing the ordered parts into supplemental parts and emergency parts. Therefore, in this inventory replenishment management system, the work of separating the ordered parts into replenished parts and emergency parts is required separately, and the ordering work becomes complicated.

  The present invention has been made in view of such a point, and the object of the present invention is to provide an appropriate inventory amount in a predetermined period in the future for a plurality of bases that own and manage vehicle parts such as automobiles. An object of the present invention is to provide a technology for simplifying the ordering work of the parts in the vehicle parts inventory management system and method for holding the parts.

  The first invention is provided for a plurality of bases that are provided so as to form at least three layers of a lower layer side and an upper layer side that has jurisdiction over the lower layer side, and that own and manage a plurality of types of vehicle parts. A vehicle parts inventory management system for holding each of the parts with an appropriate inventory amount in a predetermined period, a prediction means for predicting a demand forecast amount of each of the parts at each of the bases in the future predetermined period; The possession that stores the possession commit rate of each part, which indicates the ratio of the amount declared by each of the bases to the demand forecast amount of each of the parts during the predetermined period in the future. Based on the commit rate storage means and at least the demand forecast amount and the retained commit rate, the retained inventory amount of each of the parts at each of the bases in the future predetermined period is calculated, and the calculated retained inventory amount Control means for instructing each of the bases, wherein the control means receives an order for each of the parts from each of the bases, and the parts received from the base by the order receiving means. If the order satisfies the predetermined condition, the part is determined to be an emergency part, and the first base located on the upper side of the base is set as the order destination of the part, and is received by the order receiving means. When the order of the part from the base does not satisfy the predetermined condition, it is determined that the part is a supplemental part, and the second base located above the first base is set as the second base. It has an order destination change judging means as a part ordering part.

  Here, the emergency parts are parts that are urgently needed because the order quantity is larger than the current inventory quantity, and the supplementary parts are the difference between the inventory quantity held in the future predetermined period and the current inventory quantity. The parts to be refilled based on

  Thus, the order change determination unit determines that the part is an emergency part when the order of the part from the base satisfies a predetermined condition, while the order of the part from the base does not satisfy the predetermined condition. Since it is determined that the part is a supplemental part, an operation of dividing the part into an emergency part and a supplemental part becomes unnecessary. Therefore, the ordering work for vehicle parts can be simplified.

  Further, the order change determination unit determines that the part is an emergency part or a supplemental part based on whether or not the order of the part from the base satisfies a predetermined condition. Can be prevented. Accordingly, it is possible to improve the accuracy of inventory management of vehicle parts.

  In addition, when the order change determination unit determines that the part ordered by the base is an emergency part, the order base change is not the second base, but the first base that is located on the lower layer side of the second base and is close in distance to the part. In order to make an order, the parts as emergency parts can be quickly supplied to the base. Therefore, it is possible to immediately respond to the base where the emergency parts are ordered.

  According to a second invention, in the first invention, the method for placing an order from the respective bases to the order receiving means does not give information for identifying whether the part is an emergency part or a supplement part. It is characterized by.

  As a result, the method for placing an order from each base to the order receiving means does not give information for identifying whether the part is an emergency part or a supplemental part, so that the ordering work can be further simplified.

  According to a third aspect, in the first or second aspect, the order change determination unit determines that the part is an emergency part when the part is ordered from the base at a predetermined time period. On the other hand, when an order for the part from the base is made outside the predetermined time period, the part is determined to be a supplemental part.

  Thereby, it is possible to embody an order change determination unit that determines whether a part ordered by a base is an emergency part or a supplement part.

  According to a fourth invention, in the third invention, the control means is configured to instruct the holding stock amount to each of the bases only during the period other than the predetermined time period. Is.

  By the way, the emergency parts are ordered when the order quantity is larger than the current inventory quantity, and at this time, it is not necessary to instruct the holding inventory quantity to each base.

  Here, according to the present invention, since the control means is configured to instruct the stock quantity to each base only in a period other than the predetermined time period, the control means is configured to be in a predetermined time period, that is, emergency Do not specify the amount of inventory in stock at each site during the parts ordering period.

  In a fifth aspect based on the first or second aspect, when the order change determination unit is accepted by the order acceptance unit and the part order from the base is an order for a predetermined part, While it is determined that the part is an emergency part, when the order of the part from the base received by the order receiving unit is not the order of the predetermined part, the part is determined to be a supplemental part. It is comprised so that it may be comprised.

  Thereby, it is possible to embody an order change determination unit that determines whether a part ordered by a base is an emergency part or a supplement part.

  A sixth invention is provided for a plurality of bases that are provided so as to form at least three layers of a lower layer side and an upper layer side that has jurisdiction over the lower layer side, and that own and manage a plurality of types of vehicle parts. A vehicle parts inventory management method for holding each of the parts with an appropriate amount of inventory in a predetermined period, the step of predicting a demand forecast amount of each of the parts at each of the bases in the predetermined period in the future, Storing each component's possession commit rate, which is set for each site and indicates the ratio of the amount declared by each site to the demand forecast amount of each component in the predetermined future period; Based on at least the demand forecast amount and the holding commitment rate, the holding stock amount of each part at each base in the predetermined future period is calculated, and the calculated holding stock amount is instructed to each base. Do When the order of each part from each base satisfies the predetermined condition, it is determined that each part is an emergency part, and the first base located on the upper layer side of the base is designated as each part. On the other hand, when the order of each part from each base does not satisfy the predetermined condition, it is determined that each part is a supplemental part and is located on the upper layer side than the first base. And a step of using the second base as an order destination for each of the above parts.

  According to the present invention, when the order of the part from the base satisfies the predetermined condition, the order change determination unit determines that the part is an emergency part, while the order of the part from the base does not satisfy the predetermined condition. In some cases, it is determined that the part is a supplemental part, so that it is not necessary to divide the part into an emergency part and a supplemental part, and the ordering work for vehicle parts can be simplified.

  Further, the order change determination unit determines that the part is an emergency part or a supplemental part based on whether or not the order of the part from the base satisfies a predetermined condition. Ordering and the accuracy of inventory management of vehicle parts can be improved.

  In addition, when the order change determination unit determines that the part ordered by the base is an emergency part, the order base change is not the second base, but the first base that is located on the lower layer side of the second base and is close in distance to the part. Since it is an order destination, the parts as emergency parts can be quickly supplied to the base, and the base where the emergency parts are ordered can be immediately handled.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
A vehicle parts inventory management system 1 according to Embodiment 1 of the present invention is provided so as to form a plurality of layers of a lower layer side and an upper layer side having jurisdiction over the lower layer side, and a plurality of types of vehicle parts (hereinafter referred to as parts). Are used in order to have each of the above-mentioned parts possessed in an appropriate inventory quantity in a predetermined period in the future.

  As shown in FIG. 1, a sales company base (sales base) 2 that directly sells parts to customers exists as a base of a lower layer, and a child base 3 that has jurisdiction over the sales company base 2 and supplies parts to the sales company base 2 It exists as a first middle-tier base, has a parent base 4 that has jurisdiction over its sales company base 2 or child base 3 and supplies parts to the sales company base 2 or child base 3 (if there is no child base 3, the sales company base 2 Directly supervising and supplying parts to the sales company base 2 and, if there is a child base 3, directly supervising the child base 3 and supplying parts to the child base 3) exists as the second middle-tier base A domestic parts warehouse 5 that controls the parent base 4 and supplies parts to the parent base 4 exists as an upper-layer base, and is provided in a hierarchical structure from the upper layer to the lower-layer base.

  Each of the domestic parts warehouse, parent base, child base, and sales company bases 2, 3, 4, and 5 owns and manages their own parts. Further, each of the bases 2, 3, and 4 excluding the domestic parts warehouse 5 replenishes the parts from the base located immediately above the own base when the parts fall below the target stock quantity. That is, each of the bases 3, 4, 5 except the sales company base 2 replenishes the parts to the base when the parts at the base located directly below the base are below the target stock quantity. In the present embodiment, when the part falls below the target stock quantity, the sales company base 2 replenishes the part from the child base 3 or the parent base 4 located immediately above, and the child base 3 is located immediately above. The parent base 4 replenishes the parts from the domestic parts store 5, and the parent base 4 replenishes the parts from the domestic parts warehouse 5.

  The domestic parts store 5 is a base for replenishing the parent base 4 with each part supplied from a supplier 6 to be described later. For example, only one is installed in Japan. In this embodiment, the domestic parts store 5 has jurisdiction over the first and second parent bases 4a and 4b.

  The supplier 6 manufactures each part and supplies each manufactured part to the domestic parts warehouse 5 and the overseas parts warehouse 7 described later. For example, there are several hundreds in Japan. .

  The domestic parts store 5 also exchanges parts with the overseas parts store 7 described later. This overseas parts warehouse 7 is a base for replenishing overseas parts to overseas bases 8 such as the United States and Europe. For example, only one part is installed in Japan. Furthermore, the domestic parts store 5 replenishes each part to the direct sales company 9 as well.

  The parent base 4 is arranged for each local unit such as Kanto region, Kinki region, Chugoku region, and the like. In this embodiment, the first parent base 4a has jurisdiction over the first and second child bases 3a, 3b, and the second parent base 4b has jurisdiction over the fifth to eighth sales company bases 2e, 2f, 2g, 2h. . Further, the parent base 4 may replenish each part to the parts dealer 10 and the maintenance dealer 11 (in this case, the parent base 4 functions in the same manner as the sales company base 2).

  The child base 3 is arranged for each prefecture unit such as Tokyo, Osaka, Hiroshima and the like. In the present embodiment, the first child base 3a has jurisdiction over the first and second sales company bases 2a, 2b, and the second child base 3b has jurisdiction over the third and fourth sales company bases 2c, 2d.

  The sales company base 2 is a base that actually supplies each part to the customer, and is arranged, for example, for each local unit such as a municipality or a ward.

  As shown in FIG. 2, the vehicle parts inventory management system 1 is provided in a management server 12 as a prediction means and a control means, a management database 13 as a holding commit rate storage means, and a domestic parts warehouse 5. The domestic parts warehouse terminal 14, the parent base terminal 15 provided in each parent base 4, the child base terminal 16 provided in each child base 3, and each sales company base 2 are provided. Sales company base terminal 17. The management server 12 is connected to each of the domestic parts warehouse terminal 14, each parent site terminal 15, each child site terminal 16, and each sales company site terminal 17 via a communication line.

  The management server 12 performs various operations in order to cause each of the bases 2, 3, 4, and 5 to hold each part with an appropriate inventory amount in a future predetermined period. An outline of the operation of the management server 12 will be described later.

  The management database 13 is configured to be accessible from the management server 12, and each of the bases 2, 3, 4 and 5 has various data (in order to hold each part with an appropriate inventory amount in a predetermined period in the future ( Information). The various types of data include order data, parts group data, inter-site holding relationship data, ownership data, space data, and transient data extraction data. The order data is data of orders received for each part at each of the bases 2, 3, 4, and 5.

  The part group data is data of a plurality of basic part groups. Here, the basic component group is a group of a plurality of components divided into groups of mutually related components. For example, when a plurality of parts are classified by “item”, these parts are divided into basic parts groups such as “rotary engine parts”, “reciprocating engine parts”, and the like. Further, when a plurality of parts are classified according to “applied vehicle type”, these parts are divided into basic parts groups such as “A car” and “B car”. Base data of these basic component groups is input in advance, and the management database 13 stores the base data. In addition, parts can be added, changed, or deleted from the base data of the basic part group. Furthermore, a combination component group can be set by combining some of these basic component groups.

  The inter-base holding relationship data is holding relationship data. Here, the holding relationship refers to a relationship in which parts are held between two bases. This holding relationship can be set between two bases in units of parts or in units of combined parts groups.

  The holding ratio data is data of a minimum holding ratio, a holding commit ratio, and a temporary holding commit ratio. Here, the data of the minimum ownership rate includes data of “minimum ownership rate of the combination part group” and data of “minimum ownership rate of the total parts”. “Minimum holding ratio of combination parts group” indicates the ratio of the minimum amount that each base 2, 3, 4, 5 should hold to the demand forecast amount of the combination parts group in a predetermined period in the future. . The “minimum holding ratio of total parts” indicates the ratio of the minimum amount that each of the bases 2, 3, 4, 5 should hold with respect to the total demand forecast amount in a predetermined period in the future. The “minimum holding ratio of the combination component group” can be set for each combination group at each of the bases 2, 3, 4, and 5. “Minimum holding ratio of total parts” is automatically set for each base 2, 3, 4 and 5 by setting “minimum holding ratio of combination parts group” as described above.

  The holding commitment rate is also called a holding reservation rate, and indicates the ratio of the amount declared by each of the bases 2, 3, 4, 5 to the demand forecast amount of each part in a predetermined period in the future. The possession commit rate is set to a value equal to or higher than the minimum possession rate, and can be set for each part or each combination part group at each of the bases 2, 3, 4, and 5.

  The temporary holding commit rate is temporarily used instead of the above-mentioned holding commit rate. This temporary possession commit rate is set to a value smaller than the possession commit rate, and can be set for each part or each combination part group at each of the bases 2, 3, 4, and 5.

  The space data includes data on the size of each part and data on the space where each part can be placed at each of the bases 2, 3, 4, and 5. Here, the placeable space is a space in which parts can be placed at each of the bases 2, 3, 4, and 5.

  The transient data extraction data is data for extracting transient data. Here, the transient data is transient order data resulting from a disaster or a sales promotion campaign.

  The domestic parts warehouse terminal 14 has an input keyboard and an output display, and receives the order data of each part in the domestic parts warehouse 5 and the data of the current inventory amount of each part to the management server 12. And the function of receiving from the management server 12 data on the inventory amount, minimum possession rate, possession commit rate, and temporary possession commit rate of each part in the domestic parts warehouse 5. Here, the current inventory quantity is an inventory quantity that each base 2, 3, 4, 5 is considered to actually hold, and the inventory inventory quantity is each base 2, 3, 4, 5 Is the amount of inventory that should be held in a future period.

  The parent site terminal 15 has a keyboard and a display. The parent site terminal 15 has a function of transmitting order data of each part at the parent site 4 and data of the current inventory quantity of each component to the management server 12, and the parent site 4 Have a function of receiving from the management server 12 data on the inventory amount, minimum ownership rate, ownership commit rate, and temporary ownership commit rate of each part.

  The child base terminal 16 has a keyboard and a display. Each child base 3 has a function of sending order data of each part and data of the current inventory amount of each part to the management server 12, and It has a function of receiving from the management server 12 data on the inventory amount of parts, the minimum holding rate, the holding commit rate, and the temporary holding commit rate.

  The sales company base terminal 17 has a keyboard and a display, a function of transmitting order data of each part at the sales company base 2 and data of the current inventory amount of each part to the management server 12, and the sales company base 2 Have a function of receiving from the management server 12 data on the inventory amount, minimum ownership rate, ownership commit rate, and temporary ownership commit rate of each part.

-Operation of vehicle parts inventory management system-
Here, an outline of the operation of the vehicle parts inventory management system 1 when each of the bases 2, 3, 4 and 5 receives an order for parts will be described with reference to the flowchart of FIG. 3 and FIG. Note that the above-mentioned holding relationship is set in advance between predetermined bases.

  First, the order data such as the part number and quantity of the ordered part is input to the terminals 14, 15, 16, and 17 at each base (step S1). Next, the received order data is transmitted to the management server 12 from the terminals 14, 15, 16, and 17 at each site, and the management database 13 stores the order data (step S2).

  Next, the management server 12 extracts temporary data from the stored order data, and performs predetermined processing on the extracted temporary data (step S3). Next, the management server 12 calculates the predicted number of orders received in a future predetermined period for each part at each of the bases 2, 3, 4, and 5 based on the stored order data, that is, actual demand results (step S4). ). Here, the predetermined period is a period determined by the lead time of each component and the ordering method of each base 2, 3, 4, 5.

  Next, the management server 12 sets and stores at least the predicted number of orders for each part at each base 2, 3, 4 and 5 in the predetermined period in the future and each combination part group at each base 2, 3, 4, and 5. Based on the determined minimum holding ratio, the holding inventory amount of each part of each base 2, 3, 4, 5 in a predetermined period in the future is calculated.

  Next, the management server 12 receives information on the minimum holding ratio set and stored for each combination component group or each component at each of the bases 2, 3, 4 and 5, and each base 2, 3 in a future predetermined period. , 4, and 5 are transmitted to the terminals 14, 15, 16, and 17 of the respective bases. After that, the terminals 14, 15, 16, and 17 at each site have the minimum holding ratio set and stored for each combination component group and the components of each site 2, 3, 4, and 5 in a predetermined future period. The inventory amount held is displayed. Then, in accordance with these minimum holding rate and holding stock amount, the holding commit rate is input to each terminal group 14, 15, 16, 17 for each combination component group, and then the input holding commit rate Is transmitted to the management server 12 from the terminals 14, 15, 16, and 17 at each site (step S5).

  Next, the management server 12 predicts the number of orders received for each part at each of the bases 2, 3, 4, and 5 in the predetermined period in the future, Based on the possessed inventory amount of each component at the base, the retained inventory amount of each component at each of the bases 2, 3, 4, and 5 in a future predetermined period is calculated (step S6). Here, the subordinate bases are all bases located immediately below the bases 3, 4, 5 except the sales company base 2. Further, the target holding ratio is either the minimum holding ratio or the holding commit ratio. The stock amount of each part at each of the bases 2, 3, 4, and 5 in a predetermined period in the future is obtained by the following equation (1). However, in the case of the sales company base 2, “the amount of inventory of each part of the subordinate base in a predetermined future period” described later is set to zero.

Inventory amount of each part at each base in the future predetermined period = {(Predicted number of orders for each part at each base in the predetermined period in the future) + (Stock quantity of each part at lower bases in the predetermined period in the future)} × (Target share of each part at each site)… (1)
When each of the bases 2, 3, 4, and 5 uses the temporary holding commit rate for a predetermined period instead of the holding commit rate, the management server 12 holds the target holding rate used in the above equation (1). Use the temporary holding commit rate instead of the commit rate.

  Next, the management server 12 transmits the information on the inventory amount of each part of each of the bases 2, 3, 4, and 5 in a predetermined future period to the terminals 14, 15, 16, and 17 of each base. In addition, the management server 12 transmits information on the inventory amount of each component of each of the bases 2, 3, 4, and 5 during the predetermined period in the future outside the business hours of each of the bases 2, 3, 4, and 5. .

  Next, the terminals 14, 15, 16, and 17 at each site calculate the number of urgent orders or the number of replenishment orders that indicate the shortage of the parts at each site 2, 3, 4, and 5 (step S7). The number of urgent orders and the number of replenishment orders for each part at each of the bases 2, 3, 4, and 5 can be obtained by the following equations (2) and (3), respectively.

Number of urgent orders for each part at each site = (Number of orders received for each part at each site)-(Current inventory amount of each part at each site) (2)
Number of replenishment orders for each part at each site = (inventory amount of each part at each site in a predetermined period in the future)-(current inventory amount of each part at each site) (3)
The above-mentioned “current inventory amount of each part at each base” is obtained by the following equation (4).

The current inventory of each part at each site = (the number actually held) + (the number already ordered but not yet received)-(already ordered but still shipped) No number) ... (4)
Next, the management server 12 transmits information such as the inventory amount of each part of each base 2, 3, 4 and 5 and the number of emergency orders or the number of supplementary orders to the terminals 14, 15, 16, and 17 of each base. The terminals 14, 15, 16, and 17 at each base display (instruct) information such as the inventory amount of each part and the number of emergency orders or the number of supplementary orders.

  Next, in accordance with the number of urgent orders or the number of replenishment orders, the order data such as the part number and quantity of parts to be ordered, the order time, etc. are input to the terminals 14, 15, 16, 17 at each base (step S8). The input order data is transmitted to the management server 12 from the terminals 14, 15, 16, and 17 at each site. The order data input method to the terminals 14, 15, 16, and 17 for ordering from the respective bases 2, 3, 4, and 5 to the management server 12 is an emergency part or a supplemental part to be described later. Information that identifies whether or not there is not given.

  Next, the management server 12 or the terminals 14, 15, 16, and 17 at each site determine the ordering method based on the transmitted ordering data (step S 9).

  Here, the process of determining the ordering method by the management server 12 or the terminals 14, 15, 16, and 17 at each base will be described in detail with reference to the flowchart of FIG.

  First, the management server 12 or the terminals 14, 15, 16, and 17 at each site determine whether or not the ordering time of the ordering site is within the business hours of the site (step S11). The predetermined time zone according to the present invention corresponds to the business hours of the base.

  Next, if it is determined that the time of ordering is within the business hours of the base, the management server 12 or the terminals 14, 15, 16, and 17 of each base determine that the part ordered by the base is an emergency part. . Here, the emergency parts are parts that are urgently needed because the number of orders received is larger than the current inventory amount. Then, the management server 12 or the terminals 14, 15, 16, and 17 of the respective bases set the bases located immediately above the bases as parts ordering destinations corresponding to the number of emergency orders (step S12). For example, when the order source is the first sales company base 2a, the management server 12 or the terminals 14, 15, 16, and 17 of each base use the first child base 3a as an order destination for parts corresponding to the number of urgent orders. Is the first child base 3a, the management server 12 or the terminals 14, 15, 16, and 17 of each base use the first parent base 4a as an ordering place for parts for the number of emergency orders (see FIG. 6). .

  On the other hand, as shown in FIG. 5, if it is determined that the ordering time of the ordering base is not within the business hours of the base, that is, it is determined that it is outside the business hours, the management server 12 or the terminals 14, 15, 16 and 17 determine that the part ordered by the base is a supplemental part. Here, the supplemental part is a part that is supplemented based on the difference between the retained inventory amount and the current retained inventory amount in a predetermined period in the future. As shown in FIG. 6, the management server 12 or the terminals 14, 15, 16, and 17 at each base use the domestic parts warehouse 5 as an ordering destination for parts for replenishment orders (step S 13).

  Next, as shown in FIG. 3 and FIG. 4, when the management server 12 or the terminals 14, 15, 16, 17 of each site determines that the part ordered by the ordering site is an emergency part, that site While sending information instructing the ordering base to replenish parts for the number of emergency orders to the terminal at the base located directly above the part, the parts ordered by the ordering base are replacement parts. If it is determined that there is, the information for instructing to replenish parts for the replenishment order to the ordering base is output to the domestic parts warehouse terminal 14 (step S10).

  Finally, the domestic parts warehouse terminal 14 instructs the supplier 6 to procure the necessary number of parts.

-Effect-
As described above, according to the present embodiment, when the management server 12 or the terminals 14, 15, 16, and 17 of each base determine that the ordering time of the ordering base is within the business hours of the base, the base is While it is determined that the ordered part is an emergency part, if it is determined that the ordering time of the ordering base is outside the business hours of the base, the part ordered by the base is determined to be a supplemental part. There is no need to separate the parts into emergency parts and replacement parts. Therefore, the ordering work for vehicle parts can be simplified.

  Also, the management server 12 or the terminals 14, 15, 16, and 17 at each site can determine whether the part is an emergency part or a supplemental part based on whether or not the order of the part from the ordering base is within business hours. Since it is determined that there is, it is possible to prevent an emergency part and a replacement part from being ordered by mistake. Accordingly, it is possible to improve the accuracy of inventory management of vehicle parts.

  In addition, when the management server 12 or the terminals 14, 15, 16, and 17 at each site determines that the part ordered by the ordering site is an emergency part, the domestic parts warehouse 5 is not the domestic parts warehouse 5. Since the base located near the distance and located near the distance is used as the order destination for the parts, the parts as emergency parts can be quickly supplied to the ordering base. Therefore, it is possible to immediately respond to the base where the emergency parts are ordered.

  Thus, in the order data input method to the terminals 14, 15, 16, and 17 for ordering from the respective bases 2, 3, 4, and 5 to the management server 12, the parts to be ordered are emergency parts or supplement parts. Since no information for identifying these is given, the ordering work can be further simplified.

  By the way, the emergency parts are ordered when the order quantity is larger than the current inventory quantity. At this time, it is necessary to instruct the bases 2, 3, 4, and 5 on the information on the predicted order quantity. Absent.

  Here, according to the present embodiment, the management server 12 regards the information on the predicted number of orders for each part at each of the bases 2, 3, 4, 5 in the future for a predetermined period in each base 2, 3, 4, 5. Therefore, the management server 12 does not instruct each of the bases 2, 3, 4, and 5 during the business hours, that is, during the emergency parts ordering time period.

(Embodiment 2)
In the vehicle parts inventory management system 1 according to the second embodiment, the management server 12 or the terminals 14, 15, 16, and 17 at each site determines whether or not the parts ordered by the site from which the order was placed are predetermined parts. The ordering method is discriminated. The other points are almost the same as in the first embodiment.

  First, as shown in the flowchart of FIG. 7, the management server 12 or the terminals 14, 15, 16, and 17 of each base determine whether or not the part ordered by the base of the ordering source is a predetermined part (step) S14). Here, the predetermined component is, for example, a large component that requires a considerable space for possession.

  Next, when it is determined that the ordered part is not a predetermined part, the management server 12 or the terminals 14, 15, 16, and 17 at each base determine that the ordered part is an emergency part. Then, the management server 12 or the terminals 14, 15, 16, and 17 at each site sets the site located immediately above that site as the supplier of the parts for the emergency order (step S15).

  On the other hand, as shown in FIG. 7, if it is determined that the ordered part is a predetermined part, the management server 12 or the terminals 14, 15, 16, and 17 at each base determine that the ordered part is a supplemental part. To do. Then, the management server 12 or the terminals 14, 15, 16, and 17 at each base use the domestic parts warehouse 5 as an ordering destination for parts for supplementary ordering (step S16).

  As described above, the same effect as in the first embodiment can be obtained.

  In each of the above embodiments, as shown in FIG. 6, when the ordering source is the first or second child base 3a, 3b, the management server 12 or the terminals 14, 15, 16, 17 at the bases Although one parent site 4a is an ordering destination for parts corresponding to the number of urgent orders, an adjacent child base 3 may be an ordering destination for parts corresponding to the number of urgent orders. That is, when the ordering source is the first child base 3a, the management server 12 or the terminals 14, 15, 16, and 17 of each base may use the second child base 3b as an ordering part for parts corresponding to the number of emergency orders.

  As described above, the present invention is useful for a system or the like for holding each of the above parts with an appropriate inventory amount for a predetermined period in the future for a plurality of bases that own and manage parts for vehicles such as automobiles. It is.
