Delivery production plan makes system, delivery production plan method for making and delivery operational method

Technical field

The present invention relates to the delivery production plan making the production plan of delivery product being carried out the delivery operation of loading onto ship to boats and ships and make system and delivery production plan method for making.

Background technology

The delivery product of the such product site of storage keeping in the warehouse formed by multiple or product field to be carried out in the delivery operation of loading onto ship to boats and ships, when delivery product is (following, sometimes referred to as product) delivery when to close on period, the shipment harborage using haulage equipment that delivery product is carried to vessel berth from each product site of storage in order to load onto ship is (following, also referred to as delivery harbour, or sometimes referred to as harborage or harbour) the harbour product that arranges places position.Further, the delivery product placing position carrying to harbour product loads in ship by being located at the shipment hoisting crane of shipment harborage.

It should be noted that, delivery product method for carrying from position to harbour product that place places the position at position and different according to the position of product site of storage and harbour product.When having harbour product to place position in the movable area of hoisting crane being located at product site of storage, hoisting crane is utilized directly to be moved into by delivery product to harbour product placement position.Below, by hoisting crane also referred to as Cr.

But, when not having harbour product to place position in the movable area of the hoisting crane of product site of storage, need to place position carrying delivery product from product site of storage to harbour product.Usually, use fork lift to implement apart near carrying more.When using fork lift, the hoisting crane of product site of storage delivery product is moved to product that fork lift comes in and goes out temporarily places position, then delivery product is carried to harbour product placement position by fork lift.

On the other hand, when placing the distance at position from product site of storage to harbour product, carrying is elongated for cycle time, therefore uses product carrying vehicle as the equipment once carrying a large amount of delivery products.Also there are various sizes in product carrying vehicle, and the product volume that can load is different, but large-scale structure, become the structure that chassis (tray) part can be separated with tractor truck part.By the structure that can be separated, in the handling to chassis (tray), tractor truck can carry out the transport operation of other chassis (tray), therefore realizes the efficient activity operated.But the number that it is possible to the chassis (tray) of the carrying-in/carrying-out mouth being configured at warehouse exists the upper limit, need to consider that this restriction carrys out executable operations.

In above-mentioned delivery operation, when the transport operation of product to harbour product placement position of delivering concentrates on specific time-bands, the hoisting crane of product site of storage or the working load of haulage equipment raise, and the what is called supply shortage that delivery product postpones to the due in that harbour product places position occurs.When harbour product places position generation supply shortage, the ship-loading operation of delivery product interrupts, and therefore the stopping time of logistics leading time or boats and ships is elongated, and result is that logistic efficiency declines and logistics cost increase.Therefore, as the method making the production plan of delivery operation in order to avoid occurring to run out of goods, various scheme is proposed.

But, in order to make delivery operation production plan needed for time along with the change of the scale (such as, the size etc. of a number of product site of storage, shipment hoisting crane number, harborage number that boats and ships can berth and boats and ships) of the number of delivery product and the delivery equipment that uses of delivery operation large and increase.And delivery operation is easily subject to the impact of the essential factor such as voyage conditions variation of the operation variation of factory, weather, boats and ships, and the production plan thus sometimes made cannot utilize, and must make production plan again.

From such background, patent documentation 1 discloses a kind of product stream control setup of the frequency for reducing the production plan making delivery operation again.This product stream control setup monitors the deviation of production plan and the actual delivery operation of making, the situation of standard value has been exceeded at inclined extent, when namely predicting the generation supply shortage of harbour product placement position, carry out in the mode preferentially performing supply shortage generation operation process of jumping a queue.

First, in the process of STEP1, generated the operation utilizing handling equipment, haulage equipment to carry out particularly by data handle before happening portion 51.

Such as, there is following situation in the loading and unloading operation that warehouse crane A11 ~ 92 are carried out.

(1-1-1) product warehousing (carrying vehicle) operation: product moves in warehouse from tray

(1-1-2) product warehouse-out (utilizing carrying vehicle to factory or other movements) operation: product moves from warehouse to tray

(1-1-3) to deliver product warehouse-out (utilizing fork lift to be carried to the product of harbour) operation: from the movement to the shop front in warehouse

Information (carrying product, batch) for generating the operation of (1-1-1) and (1-1-2) obtains from product information DB31 and carrying plan information DB33.And, (1-1-3) list of the product of delivering in harborage 1 ~ 3 is extracted from shipment schedule DB34, wherein, extract based on product information DB31 and carrying plan information DB33 and generate stock in the product of A1 ~ 9, product warehouse or the predetermined product of the warehouse-in of A1 ~ 9.

When generating the operation of (1-1-1) ~ (1-1-3), development situation DB32 must be confirmed, the operation completed is removed.And, carry out (1-1-1) ~ being decided by the management information table shown in Fig. 3 or inventory information table of the operation of (1-1-3), but the actual hoisting crane carrying out operation did not determine before STEP6 described later.The time of each operation cost sets based on facility information DB2.

Then, there are following 2 kinds of operations in fork lift (following, sometimes referred to as fork truck).

(1-2-1) from tray by the operation (utilizing the operation of vehicle conveying) unloaded to harborage of delivery product

(1-2-2) from warehouse, the shop front (A1-1, A1-2, A9-3, A9-4) of A1 ~ 9 is carried to the operation of harborage

(1-2-2) operation according to delivery product institute stock and deliver the place of harborage and operation (carrying) time different.Therefore, production time is set based on product information DB31 (inventory information table), shipment schedule DB34 and facility information DB2 (shifting time carrying the fork truck of source ~ carrying destination is preserved) at every turn.(1-2-1) object product utilization stock/ship/hatch divides into groups by operation, is gathered by the product of each group and to make batch with the amount that can be loaded into tray.It should be noted that, when batch to gather, the mode becoming same batch with shipping sequence (record with reference to shipment schedule DB) near delivery product carries out batch gathering.Production time uses the value set according to facility information DB.Owing to becoming the operation unloaded from tray, therefore set the time shorter than (1-2-2).

It should be noted that, in the present embodiment, owing to supposing that each ship/hatch takes on operation by 1 fork lift, the fork lift therefore taken in the moment generating operation determines.

In addition, the operation of loading hoisting crane onto ship sets loading and unloading operation based on shipment schedule DB34.Production time is set with reference to facility information DB2.When shipping sequence continuously and the product of light weight, also can generate the operation of once loading and unloading multiple product.

It should be noted that, when generating operation, also adding the information such as leading successor relationship accordingly.Such as, following operation is generated about 1 product.

(1-3-1) product is moved into warehouse (warehouse crane operation)

(1-3-2) by product to shop front outbound (warehouse crane operation)

(1-3-3) product is transported to harborage (fork elevating machine operation) from the shop front

(1-3-4) by product shipment (shipment crane job)

Above-mentioned operation exists $(1-3-1)\⇒(1-3-2)\⇒(1-3-3)\⇒(1-3-4)$ Leading ordinal relation like this, subsequent job only distributes after the moment that upfront effort completes.This restriction needs when plan is made, also generate such restriction condition in STEP1.

Then, in the process of STEP2, with reference to the ship-loading operation information, the ship-loading operation planning chart shown in Fig. 6 (a) and the shipment group list shown in Fig. 6 (b) that generate in STEP1 and the harborage planning chart shown in Fig. 6 (c), utilize target to load moment calculating part 52 onto ship and calculate operation moment " target loads the moment onto ship " when need not wait for goods and carry out ship-loading operation.First, delivery product is placed position according to same shipment hoisting crane, boats and ships, hatch, harbour product and used the device of harborage to be divided into shipment group each other.Further, the leading successor relationship of the shipment group belonging to delivery product is generated according to the leading successor relationship formation condition for following shown shipment Gr..

[leading successor relationship formation condition]

(2-1-1) the identical shipment hoisting crane of ship-loading operation belonging to 2 shipment Gr. is used

(2-1-2) the identical boats and ships of ship-loading operation belonging to 2 shipment Gr. and identical hatch is used

(2-1-3) the identical harbour product of ship-loading operation belonging to 2 shipment Gr. is used to place position

(2-1-4) the identical harborage of ship-loading operation belonging to 2 shipment Gr. is used and different boats and ships.

In 2 the shipment Gr. setting up leading successor relationship data, a side of morning shipment start time of Fig. 6 (a) is as upfront effort, and a side in evening processes as subsequent job.Fig. 8 is the figure of the example schematically showing leading successor relationship data.Such as, FN0001 and FN0003 is the operation group that ship (F425) is identical with hatch (#1).This group cannot process simultaneously concurrently, therefore after either party completes, performs the opposing party.In the figure, the shipment start time of FN0001 is more Zao than FN0003, therefore generates the relation of FN0001 prior to FN0003.Select the shipment Gr. meeting following condition in shipment Gr., calculate the target ship-loading operation moment of the ship-loading operation of the Gr. belonging to selected.

[shipment Gr. alternative condition]

The operation moment that the target shipment moment belongs to the ship-loading operation of the shipment Gr. of " the leading shipment Gr. " do not calculated can determine according to the shipping sequence of Fig. 6 (b).In this case, the operation moment is determined to become than mode rearward of following moment.

(2-2-1) leading Gr. completes the moment (situation that different ships, the situation of hatch also comprise the additional prior operation moment)

(2-2-2) leading warehouse crane, fork elevating machine operation (result of STEP1) complete the moment

About above-mentioned (2-2-2), such as, when there is input work as upfront effort, in Figure 5, the shop front based on object product arrives predetermined instant, the warehouse crane production time of facility information DB2, fork lift transport operation time (1-2-2) carry out computational tasks early start may the moment, sets the ship-loading operation moment of object product after this moment.When there is the restriction condition of (2-2-2), object product by ship-loading operation before can produce floor time.

In the present embodiment, to arrange the equipment of 2 hoisting cranes for object in 1 warehouse.Operation is taken in order to distribute to these 2 hoisting cranes, region in warehouse is split, warehouse crane time of run is divided into multiple production time band, each production time split is brought to the warehouse crane (allocation process is carried out in STEP7) distributing and Nei Ge region, warehouse is taken on to operation.

Figure 14 is the figure of an example of the site of storage definition represented in warehouse.In the drawings, as an example, the example of an A1 with 18 row 10 row site of storages and 3 shop fronts is shown.

The information relevant to the region in warehouse defines with " the depot area definition standard " that be stored in facility information DB2.Figure 15 is the figure of the example representing depot area definition standard.As shown in figure 15, the region 1 of a such as A1 is confirmed as the scope of the first row to the 6th row.

In addition, about the shop front, also determine to belong to which region.Figure 16 is the figure of the example representing carrying-in/carrying-out mouth information.Carrying-in/carrying-out mouth information is the information which position is the shop front be in, and is stored in facility information DB2.In figure 16, the A1-1 shop front represent the first row being positioned at A1 warehouse more by end side, the region belonging to the area information known A1-1 shop front of itself and Figure 15 is the region 1 (selecting nearest region) of A1.

Fig. 9 is the figure representing the example that hoisting crane distributes.In the figure, production time band is split by every 10min, the hoisting crane (in A11, A12 which) taking on each region is distributed.2 these two sides of hoisting crane (A11 and A12) of A1 carry out loading and unloading operation simultaneously situation in region 1 physically may.But carry out plan when allowing such situation when making, the action of hoisting crane is complicated and be difficult to make a plan, or hoisting crane is easily interfered each other, therefore easily occurs the impact of Operating Ratio etc.Therefore, in the present invention, in order to simplify problem, what take on loading and unloading operation in a region at 1 fixed time band is only 1 hoisting crane.

Then, in STEP3, collect handling part 531 by operation, carry out according to the region in warehouse warehouse homework being gathered and generate the process of operation group, or by the process of warehouse homework to each region allocation.In the present embodiment, the contents processing about following 3 kinds of warehouse homeworks is described.

(3-1-1) Delivery ( then taken out of by vehicle)

(3-1-2) Delivery ( then taken out of by fork truck)

(3-1-3) input work ( )

(3-1-1) and (3-1-2) be the operation product of keeping in warehouse being carried out outbound, therefore decide region according to site of storage information in warehouse and depot area definition standard.

About the input work of (3-1-3), when deciding site of storage (region) according to product size, extract the size of the product of warehouse-in, to the region allocation operation belonging to it.In the debatable situation of site of storage, or can carry out selecting from several place, such as, decide region (shop front) by following process.

STEP3-1: input work (batch) is arrived predetermined instant order early according to the shop front and sorts

STEP3-2: select a unappropriated beginning operation (batch) of region (shop front)

STEP3-3: according to each shop front extract by select batch to the shop front in batch (comprising outbound) that the shop front that can move into distributes occupy finish time the latest batch

STEP3-4: select described extraction batch in the shop front occupy finish time the earliest batch, to be assigned with this batch batch the shop front (region) distribution object batch (shop front off-capacity and do not distribute to due in when, by the operation moment to staggering after necessary bottom line and distributing)

STEP3-5: if unappropriated batch does not have, then terminate, if also have, then returns STEP3-2

The above process that to be treated as with the situation of the load equalization of the shop front be target.By above process, according to region, group areas is pressed in cranage operation.

Then, in STEP4, by handling production time band calculating part 532, temporarily decision is to the operation moment of the operation of region allocation in STEP3, operation is gathered according to time-bands.About the warehouse-in Delivery of the vehicle conveying relation of above-mentioned (3-1-1), (3-1-3), consider shop front capacity and temporarily determined the operation moment, the operation moment method of calculating example of (3-1-2) has therefore been shown here.

[going out shop front production time method of calculating]

STEP4-1: target shipment start time (calculating in STEP2) of searching object delivery product

STEP4-2: the first line time (setup parameter) of outbound of extracting object delivery product from facility information DB

STEP4-3: calculate from the target shipment moment and be advanced by moment of the leading time quantum of outbound, and go out shop front operation (3-1-2) start time as warehouse crane

By above process, temporarily determine the operation moment that (3-1-1) ~ (3-1-3) is whole.

And, in STEP5, pile up by load the calculating that calculating part 533 carries out warehouse homework load and placement position load.

[method of calculating of warehouse crane working load]

Based on the temporary transient allocation result of STEP4, in same (region) group job, calculate the aggregate values of the product quantity in every same time-bands process, it can be used as working load.

[product places the method for calculating of position load]

Product is placed position load meter and is shown the product quantity being in product placement position.When product uses fork lift and is carried to harbour, the placement position that this product passes through is two places.One be the warehouse shop front shop front product place position, another be harbour harbour product place position.When the product quantity (placing position load) at these products placement position reaches product placement section bit capacity, product cannot be put into further, therefore need consideration capacity to restrict and make a plan.

Figure 10 represents that 1 product occupies the figure that 2 are placed the time-bands at position.During the movement from warehouse crane to fork truck to the operation of shop front movement starts, product occupies the shop front and places position, and during moving from fork truck and being accomplished to till ship-loading operation completes, product occupies harbour and places position.Namely move according to fork truck and in which time carry out and place position load and change, but use following calculating in order to avoid complication, temporarily determine that fork truck moves the moment and calculates and place position load.

[fork truck moves moment calculating]

Figure 11 represents that fork truck moves the figure of the method that the moment calculates.

STEP5-1: calculate the scope (condition 1 of Figure 11) that fork truck shifting time band enters

STEP5-2: calculate fork truck and move early finish date (condition 2 of Figure 11)

STEP5-3: by satisfying condition 1, the moment the earliest of these both sides of condition 2 is set to fork truck and moves the moment, in the moment of the condition meeting both sides non-existent situation, the revise goal shipment moment.

For delivery product (carrying fork truck part), calculating above-mentioned fork truck and move the moment, when there being the fork truck mobile operating time-bands of same ship/hatch to repeat, avoiding the mode corrected time of repetition to be with to make a rear, direction stagger.In the fork truck shifting time band that this calculates, advanced fork mobile operating before the placement section bit capacity upper limit close to harbour.Thus, later without the need to considering the placement section bit capacity of harbour again, as long as only consider that the capacity at shop front placement position restricts and carries out the front process (the avalanche process of STEP6) of warehouse loading and unloading operation.

When fork truck moves moment decision, decide the holding time band at the shop front and harbour placement position based on Figure 10.For each product calculate this occupy between the time span of part of the time-bands (in Fig. 9 every 10min segmentation) entering aforesaid segmentation in band, the aggregate values (full product volume) calculating described time span is brought for each placement position, each sliced time.This time span aggregate values becomes places position load value.

Then, in STEP6, perform load avalanche and calculate.Warehouse crane go out shop front operation (3-1-2) not have mode devious to carry out load equalization according to the operation group gathered by warehouse homework according to the region in time-bands, warehouse, revise the production time band of haulage equipment, avalanche process summary is below shown.

STEP6-1: by following formula, calculates the warehouse crane working load amount of exceeding for bringing each warehouse/sliced time.At this, the operation being arranged at 2 hoisting cranes of 1 distributes determined, and therefore being gathered by same 2 hoisting cranes is 1 equipment group, and considers the working out aggregate values in this working out whole region namely.

[the load amount of exceeding]=[warehouse crane working load (STEP5)]-[hoisting crane utilizable energy power]

STEP6-2: the superfluous test section 5341 of load retrieves from a side in time-bands evening the warehouse meeting following (condition A), if do not find, then terminates.

(condition A) load amount of exceeding > load is above standard value (being stored in the information of facility information DB)

STEP6-3: load surplus capacity calculating part 5342 for the time-bands/warehouse found in STEP6-2, based on following formula, for each region calculate can before the surplus capacity " place position load surplus capacity " that falls.

[placing position load surplus capacity]=([time-bands time span] × [shop front placement section bit capacity]-[shop front places position load (result of calculation of STEP5)])/[the time-bands time is long]

STEP6-4: " the load amount of exceeding " and " placing position load surplus capacity " aggregate values compare and using the value of a little side as " front fall aim parameter " by the front determination section of falling operation 5343, and select an object store crane job of the object time-bands of the amount of " front aim parameter ".

But, in this process, select crane job as met following situation.

When selection operation is removed from object time-bands, with the way selection making the difference of interregional working load reduce as far as possible

With the way selection making the selection operation number in each region be no more than the placement position load surplus capacity in each region

Selecting successively from temporarily determining operation moment (STEP4 result) operation early in the same area

STEP6-5: the front determination section of falling operation 5343 by the operation selected in STEP6-4 forward 1 time-bands move, to determine from the mode of finally carrying out distributing temporarily to determine the operation moment (with reference to Figure 13)

STEP6-6: return STEP6-1

" hoisting crane utilizable energy power " in above-mentioned STEP6-1 such as calculates according to the following formula (i is the hoisting crane ID being arranged at object store)." hoisting crane utilizable energy power " represents that equipment can process the basic parameter of how many products in object time-bands.α is yield rate coefficient, meets 0< α≤1.

[hoisting crane utilizable energy power]=Σ _i([time of run of the hoisting crane i of object time-bands]/[hoisting crane i carries out the time (facility information DB) of the loading and unloading operation cost of 1 time] × α)

The placement position load surplus capacity of STEP6-3 be consider shop front load and estimate can before the value of operation number of falling.When making to fall before the crane job of the shop front, the tank farm stock that the shop front places position increases and the increase of shop front load.By making a crane job time Tape movement forward, and budgetary estimate goes out the higher limit (Figure 12) of the shop front lifting capacity (time span aggregate values) that can increase in object time-bands, utilize the length of time-bands to be split and as can before the operation number that falls.

In addition, in STEP7, determine handling part 535 by equipment, determine the region that warehouse crane is taken in each time-bands, determine the operation that warehouse crane carries out thus.As basic consideration, become impartial mode as far as possible to make the load of hoisting crane in each time-bands and determine to take on region.Following step is carried out for each time-bands.

[warehouse crane decision treatment step]

STEP7-1: the distribution carrying out each hoisting crane of calculating object time-bands is according to the following formula had more than needed rate

[distributing rate more than needed]=([allotment higher limit]-[being assigned number])/[allotment higher limit]

STEP7-2: the distribution in alternative is had more than needed the maximum hoisting crane of rate, distributes the unallocated and operation in the region that priority picks is the highest to the hoisting crane selected

STEP7-3: terminate in the not remaining situation in unappropriated region, enter STEP7-1 in remaining situation

[the allotment higher limit] of STEP7-1 is the product number that object hoisting crane can load and unload in the time of run of object time-bands, and [allotment] is the product number being assigned with loading and unloading operation to this hoisting crane.Not being surplus capacity but more than needed " rate " due to what use, though therefore hoisting crane when loading/unloading products number is different simultaneously, also can carry out load equalization exactly.About the priority picks in region being in STEP7-2, below Fig. 9 (example of a warehouse A1) is used to be described.

There are 2 hoisting cranes A11, A12 in a warehouse A1, A11 is arranged on side, region 1, and A12 is arranged on side, region 3,2 handling can both carrying out whole region in warehouse, but (when namely A11 carries out the operation in region 3, A12 cannot carry out the operation in region 1 or region 2) cannot be interlocked.In order to observe this restriction, for 2 hoisting cranes, as following, specify the priority picks in the region of selection.This information is stored in facility information DB2.

Hoisting crane A11:

Hoisting crane A12:

By above STEP7, summary plan is made process and is completed, and in STEP8, then performs detailed planninng make process.In the present embodiment, illustrate and carry out situation about processing by following step.

STEP8 [detailed planninng make process]

STEP8-1: select operation moment debatable earliest time band.

STEP8-2: determine the operation moment of being made " using the Delivery (3-1-1) of tray " that process distributes to object time-bands by summary plan.

STEP8-3: determine the operation moment of being made " input work (3-1-3) " that process distributes to object time-bands by summary plan.

STEP8-4: to being made the Delivery (3-1-2) of fork truck " use " that process distributes to object time-bands by summary plan and carrying fork truck operation (1-2-2) distributes, as required input work (3-1-3) low for relative importance value is postponed.

STEP8-5: if operation moment debatable time-bands does not exist, then terminate, if also exist, then enter STEP8-1.

Above-mentioned steps is suitable for the low situation of the priority picks of input work in operation.The situation that warehouse-in product is delivered rapidly is few, and therefore the input work time gives the delivery impact that operation causes little.Even if be suitable for above-mentioned step being postponed by input work compared with outbound in also no problem judgement like this.

The process details of STEP8-4 are below described.In STEP8-4, according to following flow process, decided for warehouse crane operation and these two kinds of operations of carrying fork truck operation (traveling) the operation moment.

[Delivery (fork truck delivery part) allocation process step]

STEP8-4-1: successively temporarily determined the operation moment (" the temporary transient dispenser of product transport operation (541) " carries out this process) for carrying fork truck operation from finally from the product in target ship-loading operation evening in moment.

STEP8-4-2: in the operation moment of Delivery debatable delivery product, selects a target ship-loading operation moment delivery product the earliest.

STEP8-4-3: calculate the operation number meeting the unallocated operation (the debatable operation of operation moment) of following condition.

The warehouse crane identical with selected delivery product is utilized to carry out outbound (then fork truck delivery)

The mode of carrying out processing with the time-bands identical at the delivery product with selected utilizes summary plan to distribute

STEP8-4-4: the Delivery moment determining the delivery product selected, but observe following condition.

The shop front stock number of the delivery product distributed is no more than higher limit (capacity)

when falling too, there is the possibility exceeded

By the delivery product of STEP8-4-3 as much as possible in the outbound of object time-bands

When for distributing the floor time deficiency of the delivery product of STEP8-4-3, by the moment that the input work (3-1-3) distributed low for relative importance value staggered after necessity minimal time

STEP8-4-5: fall before the carrying fork truck operation of the delivery product of selection is carried out in the scope not violating the restriction of harbour product placement section bit capacity. relax the restriction of shop front capacity thus

Above, the processing and utilizing " warehouse loading and unloading operation dispenser (542) " of STEP8-4-2 ~ 8-4-5 is carried out.

STEP8-4-6: if operation moment debatable Delivery does not exist, then terminate, if also exist, be then back to STEP8-4-2.

By more than, the explanation of the content that ends process.

[embodiment 2]

In the present embodiment, illustrate that the delivery production plan for the delivery operation be separated to delivery harborage from the such delivery product site of storage in warehouse or product field is made.Figure 17 represents that the delivery production plan of embodiment 2 is made object that system makes production plan and namely to be delivered the schematic diagram of a structure example of equipment.

Because the transport distance from warehouse to harbour is elongated, does not therefore use fork lift and use carrying vehicle.Carrying vehicle once can carry product more more than fork lift.And, be the unsegregated structure of tractive unit and chassis portion by the carrying vehicle that delivery product is carried to harbour.Below, by with the difference of embodiment 1 centered by, present embodiment is described.

[Proposed Shipping Schedule/actual achievement information]

In embodiment 2, owing to being separated from warehouse to harbour, therefore there is Proposed Shipping Schedule information is not the possibility that only can obtain as the information of paper as electronic data.When the plan information obtained is paper information, by handwork, Proposed Shipping Schedule is inputted from condition entry portion to system.

The plan information of input is stored in shipment schedule DB with the form of Fig. 6.And also there is the situation that cannot obtain as electronic data in the shipment actual achievement information (Fig. 4 (b)) outside factory.In this case, obtain the loading/unloading products number information (loading the information of the product number in ship) of each shipment hoisting crane termly, by this information from the input of condition entry portion, judge whether product has loaded and unloaded according to warehouse Cr operation actual performance information (Fig. 4 (a)) and handling order information (Fig. 6 (b)).

Further, in the operation date of completion temporal information of shipment actual achievement information (Fig. 4 (b)), the operation date of completion temporal information estimated according to described warehouse Cr operation actual performance information and handling order information is substituted into.If delivery production plan was made in the time of shipment actual achievement information updating, then can obtain high-precision plan.

[implement to beach transport]

When delivery product is carried out vehicle conveying to harbour, need the product group (carrying batch) determining once to carry.The method for making of product batches can be considered various, but have such as by identical for the keeping region in warehouse and the shipment Cr taken on is identical, the target shipment moment as far as possible near product gather in the scope meeting loaded weight and the method to make batch etc.As long as make carrying vehicle that the carrying gathered by such method batch is made warehouse homework plan to quay transportation.

Figure 18 is the figure of the job model represented when utilizing vehicle that 1 carrying batch is moved from warehouse to harbour.In initial time-bands, the warehouse shop front is occupied by carrying vehicle, and the load bed to vehicle loads multiple product.When the product based on warehouse crane has loaded, vehicle has directly rolled away from from the warehouse shop front and has left for harbour (product carrying travels).As long as product carrying travels the time span of the mobile shortest time from warehouse to harbour more than.Reason that can be longer than the mobile shortest time is, at harbour, waiting time shipment is waited for also carries a part for running time cause as product occurs.

Further, when becoming the situation that can load onto ship, by shipment Cr, delivery product is loaded in ship.When ship-loading operation completes, vehicle returns to warehouse (null is sailed) from harbour, thus next carrying batch carrying becomes possibility.Empty running time is set as the mobile shortest time between harbour and warehouse.

In above-mentioned [embodiment 1], fork truck can unload product to harbour, therefore, it is possible to make fork truck shifting time band in restriction condition lower slider.But in the present embodiment, before shipment Cr unsnatches goods from carrying vehicle, carrying vehicle must stay in harbour, therefore the finish time (as long as not changing the target shipment moment) of product carrying running time band cannot change.On the other hand, the start time of product carrying running time band was decided, therefore, it is possible to adjust by warehouse Cr loading and unloading operation (the loading operation to the vehicle) moment of carrying batch.

Figure 19 is by the figure represented side by side to the transport operation of harbour of 5 carrying vehicles.Product to harbour is carried the vehicle number of units (running vehicle number of units) that can utilize and be there is the upper limit, but as shown in figure 19 by the transport operation to harbour side by side, can confirm whether this restriction is satisfied.

After summary production plan makes load accumulation calculating (STEP5) in portion, it is such that transport trolley operation supposition becomes Figure 19.In [embodiment 1], the capacity at position is placed for restriction condition with shop front product, calculate " placing position load surplus capacity " and carry out avalanche process (STEP6), but in the present embodiment, owing to not using shop front product to place position, therefore without the need to place position load surplus capacity for restriction condition.But, when make the loading and unloading operation of warehouse Cr (the loading operation to carrying vehicle) front fall time, need more carrying vehicle, therefore carrying vehicle load increase.Therefore, need to replace " place position load surplus capacity " and consider running vehicle number of units restriction ground carry out warehouse Cr operation front fall.

Figure 20 be represent carry out warehouse Cr operation front fall the figure of situation.About above-mentioned running vehicle number of units restriction, Figure 20 is used to be described.The upper figure of Figure 20 represents by the loading operation (3 coiled material amounts are carried out in warehouse A3) with [embodiment 1] STEP4,5 same process and the time of vehicle operation of carrying batch KK0002, KK0005 of temporarily determining, holding time and carrying batch KK0005.When the working load of warehouse A3 high and fall before making the loading operation of KK0005, even if the null being advanced to KK0002 the loading operation start time of KK0005 sails finish time, also can not increase running vehicle number of units.The situation of falling before making warehouse Cr operation like this becomes figure below of Figure 20.The warehouse Cr of the coiled material (3) of the carrying of front falling batch KK0005 is loaded and unloaded the moment of moment as the limit that loading operation can be made to shift to an earlier date, hereinafter referred to as " before loading the moment of falling the limit ".

In each carrying batch, each product of carrying is calculated " before loading the moment of falling the limit ", based on this carry out same with STEP6-4 before the selection of falling operation.Concrete alternative condition as mentioned below.

When selection operation is removed from object time-bands, the way selection as far as possible reduced with the difference of interregional working load

The operation that time-bands finish time before the time-bands of the operation before selecting the moment of falling limit ratio before loading to fall before distributing is Zao

In the same area from temporarily determining to select successively operation moment (STEP4 result) operation early

In addition, make in process (STEP8) at detailed planninng, also be do not consider that shop front product places the capacity restriction at position, as long as and consider running vehicle number of units restriction (restriction relevant to the load of haulage equipment) to carry out in the same manner as [embodiment 1] that the operation moment determines.

Above, for the present invention, utilize 2 embodiments to be illustrated, but in the case of the method for the present invention, make for why plan can be carried out at short notice, carry out supplemental instruction.

Such as, the number of combinations of the production plan (operation distribution and sequence of events to hoisting crane) when utilizing 2 hoisting cranes respectively to carry out the Delivery of 10 products for the Delivery of 20 products is considered.To repeat and the possibility that interferes is deposited in case in the operation range of 2 hoisting cranes, the operation of 2 hoisting cranes influences each other, and therefore needs the sequence of events of both sides to gather consideration.In this case, the number of combinations of sequence of events become 20! Number huge like this.

But, when the operation range of hoisting crane do not repeat product that such each hoisting crane takes on determine in advance, this number of combinations for each hoisting crane become 10! .That is, number of combinations significantly can be reduced to described 20! 3.3 × 10 ¹¹/ mono-degree.In the present invention, utilize this character and determine the handling equipment that use in operation in advance, thus the plan realizing the short time is made.

That is, utilize summary production plan to make portion, from the hoisting cranes of more than 2, according to each time-bands, determine 1 hoisting crane taking on the loading and unloading operation in common region in advance.

Embodiment

Use delivery production plan of the present invention to make system, carried out the delivery production plan corresponding with embodiment 1 and made.Load 24 hours of operation of the delivery equipment of hoisting cranes onto ship for 6 and made delivery production plan, result utilizes this delivery production plan to make system to make the plan of finishing in about 1 minute.Compared with the situation (about 1 hour) manually making plan, the plan time of making significantly shortens.And for the delivery production plan made self, be also compared with manually making the situation of plan, the wait goods time of shipment hoisting crane becomes less than 30%, can make actv. plan.
