[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts delivery plan for optimally delivering a part, which is handled in a vehicle or a factory for producing each part of the vehicle, to a predetermined delivery place. The present invention relates to a creation method and a parts delivery plan creation device.

[0002]

2. Description of the Related Art Production plants for vehicles and their parts are
There are a large number and types of parts to handle. It is desirable that the large number of parts be carried to a predetermined place in a convenient manner. Generally, in a site where work is performed in a line work such as a production factory, unless the predetermined parts are delivered at the predetermined place and time, the work efficiency is deteriorated.

As described above, in a production factory or the like, it is desirable that the predetermined parts are delivered at the predetermined place and time, and generally, the parts delivered by the truck to the production factory are In the factory, the trucks deliver to the storage shelves on the production line. Usually, the delivery time of parts such as trucks is predetermined, and it is important how to efficiently deliver the delivered parts to the storage shelves in the production line.

However, at this time, it is only necessary that the parts delivered to the factory can be smoothly delivered to the storage shelves of the predetermined production line, but in reality, the delivered parts are often delivered irregularly and the predetermined parts are often delivered. Sometimes it could not be delivered smoothly because it was not delivered to the storage shelves on the production line on time.

Further, when the number of delivered parts is larger than the number that can be accommodated in the accommodating shelves of the production line, it is necessary to divide the delivered plural parts and deliver them to the accommodating shelves. In this way, when a plurality of parts are divided and delivered, the delivery plan for delivering the parts, such as when and which part should be delivered and when and which part should be carried by which carrier, becomes very complicated.

[0006]

[0006] In the past, such a delivery plan was created by hand, so that it took a lot of time. Further, since the delivery plan is manually created, the decision as to how to divide and deliver the parts is left to the experience and intuition of the person who creates the delivery plan. Therefore, for example, it has been difficult to equalize the workload of each carrier. Specifically, this time when parts delivered by a delivery service such as a truck to the factory are delivered to the storage shelves of the production line by a transport vehicle, the transport vehicles place the parts on the storage shelves of the production line. It was difficult to make the time to return within a fixed time. Although it is possible to make the entire work more efficient by making the time uniform for each carrier, it is difficult to level the work of this carrier when creating a conventional delivery plan. It took a lot of time because it was a manual work to make the delivery plan.

[0007] Further, for example, since a parts list for delivery indicating which parts should be carried in which carrier in which order should be carried out by hand, which parts are located in which part of the carrier. In some cases, the person who delivered the part had to look for the part.

Also, when parts of the same type must be divided and delivered, a parts list showing the places where the parts were delivered was also created by hand, so that a prescribed error could be made due to a mistake in writing or an input error. Sometimes I put things other than parts on a carrier. In addition, even if the parts are allocated well so that the work load of the carrier is improved, when the parts are placed on the carrier, information about where the parts are and when delivering the parts, Sometimes the information wasn't accurate enough to find the part and it took a long time to deliver it.

Therefore, in order to solve the above problems, the present invention can shorten the time required to create a delivery plan, level the work of delivery, and deliver parts efficiently and reliably. An object is to provide a parts delivery plan creation method and a parts delivery plan creation device that can be delivered to a place.

[0010]

In order to solve the above problems, the present invention employs the following configurations. That is, the parts delivery plan creation method of the present invention is a parts delivery plan creation method for creating a delivery plan of a delivery vehicle for delivering delivered parts to each delivery place by a computer. Delivery position information indicating each position and a list of parts to be delivered by the delivery vehicle are recorded, the recorded delivery position information and the parts list are read out, and the above-mentioned delivery position information is used to read the above based on the read out delivery position information. The parts in the parts list are rearranged, and the parts list is output for each delivery flight of the delivery vehicle.

In this case, the parts delivery plan creating method rearranges the parts in the parts list to be delivered by the delivery vehicle in the same order as the arrangement order of the delivery locations indicated by the read delivery position information, and performs the delivery. It is desirable that the rearranged parts are allocated to the respective trolleys by the number of parts that can be loaded by the trolleys to be pulled by the car, and the parts list allocated to the trolleys is output for each delivery flight of the delivery car.

The number of parts (boxes) that can be placed on each trolley is determined in advance, and the component boxes must be placed on the trolley so that the number of boxes thus determined is not exceeded. Further, the delivery order of the above parts means the delivery order, and the delivery is made in correspondence with the arrangement order of the storage shelves in the production line.

In the parts delivery planning method of the present invention, parts (boxes) are assigned to each trolley based on the number of parts (boxes) that can be loaded on each dolly and the order of delivery. It is possible to easily know whether the box is placed, and it is possible to reliably deliver the predetermined parts to the delivery place.

The parts delivery plan creating method of the present invention is a parts delivery plan creating method for creating a delivery plan of a delivery vehicle for delivering delivered parts to each delivery place by a computer. The delivery position information indicating the position where the stored parts are placed and a list of the parts to be delivered by the delivery vehicle are recorded, and the recorded delivery position information and the parts list are read out, and the read delivery position information is read out. The parts in the parts list are rearranged based on the above, and the parts list is output for each delivery flight of the delivery vehicle.

In this case, the parts delivery plan creation method is as follows.
The delivery position information showing each position of each delivery place, the delivery position information showing the position where the delivered parts are placed, and the list of the parts to be delivered by the delivery vehicle are recorded in advance and recorded. The delivery position information and the parts list are read out, the parts of the parts list to be delivered by the delivery vehicle are rearranged in the same order as the arrangement order of the delivery locations indicated by the read out delivery position information, and the delivery vehicle pulls them. Allocating the rearranged parts by the number of parts that can be loaded by each trolley, reading the delivery position information and the parts list recorded above, and arranging the places to be delivered indicated by the read delivery position information. It is desirable that the parts of the parts list to be delivered by the delivery vehicle are rearranged in the same order as the above order, and the parts list is output for each delivery flight of the delivery vehicle.

As described above, by rearranging the order of the parts in the parts list for delivering the parts (boxes) in the order in which the delivered places are delivered, the target parts can be surely placed on the trolley in order. Is possible. The parts delivery plan creation method of the present invention is a parts delivery plan creation method for creating a delivery plan of a delivery vehicle for delivering delivered parts to each delivery location by a computer. The time required, the traveling time of the delivery vehicle, and the preparation time required to mount the parts on the delivery vehicle are recorded, and the time required to place the parts, the traveling time, and the preparation time are read, The time required for one delivery flight of the delivery vehicle is calculated by adding the time required for placing the parts, the running time and the preparation time, and a graph showing the calculated time for each delivery flight is created. It is characterized by doing.

By displaying the graph in this way, it is possible to visually know how many flights and how many flights are not the desired delivery time, and immediately adjust the number of parts for each flight. Is possible. Further, the scope of the present invention extends to a parts delivery plan creation device for executing the processing.

FIG. 1 is a diagram for explaining the flow of the overall operation of the parts delivery system in the parts delivery plan creation method according to the embodiment of the present invention.

In FIG. 1, 11 is an assembly factory applied to the parts delivery system, 12 is a parts manufacturer that manufactures the parts required for the assembly factory 11, and 13 is a parts manufacturer 12. A delivery service (a truck or the like) for delivering the parts to the assembly plant 11, 14 is a delivery service yard for receiving the delivery service 13, and 15 is a part for taking out the delivery service 13 stored in the delivery service yard 14. A forklift for carrying 16 is a delivery lane for placing the parts of the forklift 15 once in order to deliver the parts of the forklift 15 to the storage rack of the production line, and 17 is for delivering the parts from the delivery lane 16 to a predetermined storage rack. Is a delivery vehicle, 18 is a travel route of the delivery vehicle 17, and 19 is a production line.

First, there are usually a plurality of parts manufacturers 12,
Several parts (hereinafter referred to as a parts box), which are boxed by the delivery company 13 from each parts manufacturer 12, are placed on a table called a pallet and delivered to the assembly factory 11. When each delivery flight 13 arrives at a predetermined delivery yard 14, the forklift 15 or the like carries the component box to the delivery lane 16 in pallet units. Then, from the delivery lane 16, each pallet is placed on a trolley connected to a plurality of delivery vehicles 17, and the pallets are sequentially delivered to a predetermined storage rack.

Here, when the parts box is delivered to a predetermined storage rack, if there is enough space to put the parts box in the storage rack,
That is, if there is a space on the storage shelf where the pallet with the required parts box can be placed, it can be placed on a pallet for each pallet and delivered to that storage shelf, but if there is no space to place the pallet on the storage shelf, If they are delivered in pallet units, they will not fit in the storage shelves. As described above, when a component box is delivered, there are two types of component boxes, that is, a component box that can be delivered in pallet units and a component box that is unloaded from the pallet and divided and delivered.

Then, the production line 1 with this pallet as it is
The component boxes that can be placed on the storage rack 9 are placed on a pallet for each pallet and delivered (hereinafter, this component box is delivered in pallet units as direct delivery). On the other hand, if the pallet is left as it is, the parts box overflows from the storage shelf. The parts box is subdivided from the delivery yard 14 into a predetermined delivery lane 16 and delivered on a trolley (hereinafter, referred to as "required").
It is called partial delivery that the parts box is subdivided and delivered).

When carrying out this divided delivery, it is important how many parts boxes should be brought and when. That is, it is necessary to deliver the parts boxes in small parts so that the production line 19 does not run out of necessary parts and the storage boxes do not overflow.

In both of the direct delivery and the division delivery, a delivery vehicle 1 is provided with a tag (hereinafter referred to as delivery tag) indicating which component box should be placed in which storage rack.
Create every 7. Based on the delivery tag, the parts box is placed on a predetermined storage rack of the production line 19.

In addition, in the case of divisional delivery, a tag (hereinafter referred to as a divisional bill) indicating which component box should be carried by which trolley and how many boxes should be carried. in this way,
In direct delivery, pallets are placed on a trolley based on a delivery tag, and parts are placed on a predetermined storage shelf.

On the other hand, in the case of divisional delivery, first, a necessary parts box is placed on a trolley based on the division ticket, and then the parts box is placed on a predetermined storage shelf based on the delivery tag. For example, as shown in FIG. 1, the first delivery vehicle, which is the delivery vehicle 17, passes through the production line 19 and the production line 19 and is predetermined to be delivered in divided deliveries. Parts boxes are allocated.

Based on this, a CPU or the like included in the function expansion board or the function expansion unit performs a part or all of the actual processing, and the function can be realized in the above-described embodiment also by the processing.

Basically, the delivery plan is set up based on the schedule of the delivery flight 13, and the delivery plan for moving the delivery vehicle 17 so that the parts are delivered after the arrival time of the delivery flight 13. Stand up. In addition, it is possible to check the status of the used parts by collecting the kanban in each part.

In FIG. 1, a kanban 21 indicates information about all delivered parts and is provided for each part or for each kind. Kanban 21
Is for checking how much it has actually been used, and for the used parts, the Kanban 21 is stored beside the production line 19. Then, at a certain fixed interval, for example, 24 times a day, Kanban 21
By collecting information about which parts are used in the sorter room and in what amount, and giving the usage status of the parts to the delivery planning server 20, the delivery planning server 20 receives information about the usage status of the parts. It is also possible to create a delivery plan (delivery tag and split bill) that takes into consideration.

Next, FIG. 2 is a diagram showing the data handled by the delivery planning server 20 and the flow of production. In FIG. 2, the raw pipe data 22 is data necessary for managing the production work, and indicates that it is detailed data of each part. The raw pipe data 22 includes a supplier master 22-1 that records information about suppliers of parts, a uniform number master 22-2 that records information about a uniform number of each part, and delivery service 1
Delivery cycle master 22-3, which records information such as how many times 3 is delivered per day, product name master 22-4, which records information on the product name of the part, which part is required for which production line 19 Acceptance master 2 that records information such as
2-5, delivery master 22-6 that records information about delivery 13, operation time table 22-7 that records operation time required for production, product number that records product number of parts Master 22-8, Box number master 22-9, which records information about storage shelves, such as how many boxes can be accommodated in each part, etc. Master 22-9, Daily allowance, which records the number of boxes delivered per day There is a collection box number 22-10, and a database process 22-11 which records a program for processing information of each database.

The physical distribution data 23 is data relating to the parts necessary for delivering the parts to the production line 19, and the physical distribution data 23 records data such as the names of pallets in the pallet name table 23. -1, delivery car 17
Electric car name table 23-2 recording information about (hereinafter, this delivery vehicle 17 is also referred to as an electric car), time required to carry each part to a predetermined storage rack or time to put on the storage rack There is a loading time table 23-3 in which the data of the above is recorded, and a delivery order table 23-4 in which information such as which parts are arranged in the delivery lane 16 and in what order is recorded.

Further, the assembly data 24 is data relating to the production line 19 required when the parts are delivered to the production line 19, and the assembly data 24 records the data indicating the position of the storage shelf in the line address master. 24-1, there is a shelf storage box number master 24-2 for recording data such as how many parts can be placed in which storage shelf.

These raw pipe data 22, distribution data 23,
The assembly data 24 and the assembly data 24 are stored in, for example, the recording device of the delivery planning server 20, and the delivery planning server 20 creates a delivery plan based on the raw pipe data 22, the physical distribution data 23, and the assembly data 24. The recording device for recording the raw pipe data 22, the physical distribution data 23, and the assembly data 24 may not be provided in the delivery planning server 20, and may be configured to be read out when necessary via a network or the like. Then, the delivery tag or the split bill is output by an output device provided in the delivery planning server 20, for example, a printer. The delivery person delivers while looking at the delivery ticket or the split ticket.

As described above, for direct delivery, it is sufficient to create only a delivery ticket, but for split delivery, a delivery ticket and a split ticket are created. Further, in the case of divided delivery, the allocation of parts is adjusted by a multiple simulation 25 showing how to divide parts.

In this way, which delivery vehicle 17 is used to determine which parts and how many boxes are to be delivered, and the delivery plan is adjusted when delivery of parts is completed so that delivery is completed within a desired time. Then, the delivery planning server 20 performs a series of operations up to this point of creating the delivery ticket and the split ticket.

In the case of direct delivery in the delivery work by a person, the parts are placed on the delivery vehicle 17 according to the delivery tag, and the parts are delivered to the production line according to the delivery tag.
In the case of split delivery, first, the delivery vehicle 1
Then, the parts are placed on 7, and then the parts are delivered to the production line 19 by the delivery tag.

One of the features of the parts delivery plan creation system in the present embodiment is that the parts delivery plan is created by a computer or the like. Figure 3
It is a flow chart explaining the flow of operation of the parts delivery plan creation system in this embodiment, and the delivery planning server 20 performs the operation of this entire flow chart.

First, in step S1, raw pipe data 22 and physical distribution data 2 recorded in the delivery planning server 20.
3 and the basic information of the delivery parts for producing the delivery ticket or the split ticket from the assembly data 24. For example, the delivery planning server 20 reads out the necessary information from the raw pipe data 22, the distribution data 23, and the assembly data 24 recorded in the recording device, and the delivery part basic information (detailed information for each part) ( Database) is created and stored in a new storage location of the recording device.

In the present embodiment, a delivery ticket or a split ticket is created based on this basic delivery component information. The delivery parts basic information shows a list of parts used for one day, and includes information such as the number of parts boxes delivered for each part and the position of the storage shelf.

FIG. 4 is a diagram showing a specific example of a database of basic delivery part information. In FIG. 4, each record 4
a, 4b, 4c ... Show information for each component box. In each field, 41 is the name of the pallet on which the component is mounted, 42 is the name of the component, and 43 is the component's name. The product number, 44 is the name of the production line 19, 45 is the number of boxes to be delivered per day, and 46 is the delivery number which is divided into several deliveries. 47 is the number of parts boxes
The time taken for the parts delivered on that day to be delivered to the storage rack, 48 is the position of the storage rack for indicating which storage rack of the production line 19 should be delivered, and 49 is the storage rack. The number of storable parts boxes that indicates how many boxes can be stored in
Indicates when the parts will be delivered.

The field 51 is, for example, "1-6-".
In the case of "5", the information is delivered six times a day from the number on the left, and this information indicates that the information is five flights before delivery. Also,
In the case of "2-1-5", the information is delivered once every two days, indicating that this information is five flights before.

Taking the highest record 4a as an example,
"Pallet name is pallet 1, product name is part 1, product number is 00
In 1 case, one box is delivered per day, 0.5 boxes are delivered per delivery, and it takes 12 seconds for each delivery to be put into the storage rack. The position of the storage rack is A0 of A1 of the production line 19.
In 1-3, the number of parts boxes that can be stored in the storage shelf is 9,
It is delivered twice a day, and this information is the information two flights before. ” The time for placing one component box in the field 50 on the storage shelf is, for example, one component box that does not include the running time of the delivery vehicle 17 within 44 delivery times of the production line 19 with the delivery vehicle 17. Shows only the time to put on the storage shelf, and it takes 12 seconds in the case of the record 4a.

Based on this delivery part basic information, delivery service 13
The plan table (delivery tag and split bill) for smoothly delivering the parts delivered by the method to the storage shelves of the production line 19 is created. Next, in step S2, the delivery vehicle 17
Select. There are a plurality of delivery vehicles 17, one of which is selected, and the parts of the delivery part basic information are allocated to the delivery vehicle 17. In the flowchart of FIG. 3, the delivery vehicles 17 are sequentially selected until the allocation of all the parts of the delivery part basic information.

Next, in step S3, the production line 19 is selected. In step S3, the production line 19 is already set for each delivery vehicle 17, and when the delivery vehicle 17 is selected in step S2, the production line 1 is automatically set.
9 is also decided. Next, in step S4, the production line 1
When 9 is selected, the parts required for the selected production line 19 are extracted from the delivery parts basic information.

Here, the above steps S2 to S4
Will be described in detail. FIG. 5 is a specific example of a database showing information held by each delivery vehicle 17 set in advance.
In this embodiment, five delivery vehicles 17 are used (vehicles 1 to 5).

In FIG. 5, 51 indicates which delivery vehicle 17 is selected. For the selected delivery vehicles 17, "0" is valid and the delivery vehicles 17 not selected are valid.
"1" is shown as invalid. The example of FIG. 5 shows that the delivery vehicle 17 of the vehicle 1 is “0” and is selected. Vehicles 2 to 5 other than the vehicle 1
Indicates "1", which means that it is not selected.

Next, reference numeral 52 indicates the vehicle name of the delivery vehicle 17. 53 and 54 indicate whether each delivery vehicle 17 is a vehicle for divided delivery or a vehicle for direct delivery. Similar to 51, 53 and 54 also indicate “0” when valid and “1” when invalid. For example, in the vehicle 1 of FIG. 5, since the divided delivery is indicated as “0” and the direct delivery is indicated as “1”, the delivery vehicle 17 performs only the divided delivery. Further, in the vehicle 3, since the divided delivery is shown as "0" and the direct delivery is also shown as "0", it indicates that the delivery vehicle 17 performs the divided delivery and the direct delivery. In addition, in the vehicle 5,
Since the divided delivery is shown as "1" and the direct delivery is shown as "0", it indicates that the delivery vehicle 17 performs only direct delivery.

Next, 55 indicates the type of the production line 19 through which each delivery vehicle 17 passes. In the present embodiment, there are three target production lines 19, and in the example of FIG. 5, the production lines 19 N1, J1, and A1 are predetermined for each delivery vehicle 17. Further, 56 indicates a traveling time (minutes) in which each delivery vehicle 17 travels around each production line 19 once. 57 indicates the time (minutes) required for each delivery vehicle 17 to connect the next cart. 58
Indicates a time (minute) other than the traveling time 56 and the connection time 57. For example, in the vehicle 2 of FIG. 5, the traveling time required to rotate the production lines 19 "N1" and "J1" once is 7.3 minutes, and the coupling time required to connect the next trolley is 1 minute. It shows that other incidental time takes 1 minute.

Further, 59 indicates the time (minutes) required for each delivery vehicle 17 to deliver the parts, which is set for each production line 19. As will be described later, each delivery vehicle 17 is based on the time shown in the "time (minutes) 59 that is narrowed down by the cumulative input time".
Extracts the parts to be delivered from the delivery part basic information.

Reference numeral 60 indicates an allowable time (minutes) of 59 times, and reference numeral 61 indicates how much time is delayed when the time when each delivery vehicle starts delivery is delayed. As described above, when the delivery vehicle 17 is selected, it is determined whether the delivery vehicle 17 is the divided delivery, the direct delivery, or both, and further, the selected delivery vehicle 17 is selected. The production line 19 corresponding to is specified.

When the production line 19 is specified, one field is added to the basic delivery part information. Figure 6
FIG. 9 is a diagram showing that the production line 19 has been specified and one field has been added to the basic delivery component information.

In FIG. 6, a field 61 indicates whether or not each part is to be delivered to the selected delivery vehicle 17. When the first delivery vehicle 17 is selected, "target" is displayed for all parts in this field 61, and all parts are targets for delivery. Then, when the extraction is completed from the "target" parts, the field 61 of the extracted parts is displayed.
Is displayed as "Done", and is excluded from the next extraction of parts of the delivery vehicle 17.

When all the "targets" in this field 61 become "completed", the flow chart in FIG. 3 ends. That is, of the five delivery vehicles 17, if the field 61 of the fourth delivery vehicle 17 is all "completed", the flow ends at the fourth delivery vehicle. Then, in step S4, the parts necessary for the selected production line 19 are extracted from the "target" parts, and the records of the parts are collected upward.

As described above, in the prior art, the parts manually allocated once are found again, and then the parts other than the parts are allocated to the next delivery vehicle 17, so it takes time to allocate them, and an input error occurs. However, as in steps S2 to S4 of the present embodiment, the parts assigned to a certain delivery vehicle 17 are set as “completed” and the parts other than “completed” are assigned to the next delivery vehicle 17. Therefore, the allocation time can be shortened and input mistakes can be eliminated.

Next, in step S5, step S4
It is determined whether the parts extracted in step 3 are divided delivery or direct delivery. To determine whether the delivery is divided delivery or direct delivery, the number N of times of delivery by courier is calculated. Usually, when determining whether this divided delivery or direct delivery is performed, it is determined whether or not the component box placed on the pallet can be accommodated in the accommodation space of the accommodation shelf to be delivered. Therefore, it is determined whether or not the number of component boxes placed on the pallet is larger than the number of boxes that can be accommodated in the accommodation rack. That is, when the value obtained by dividing the number of boxes on the pallet by the number of boxes that can be accommodated is larger than 1, the number of boxes on the pallet is larger, and therefore, it is necessary to carry out division delivery. In the following cases, the number of boxes that can be stored in the storage rack is larger, so direct delivery is possible.

In the present embodiment, since the delivery service 13 is not actually delivered according to the schedule, the components are placed on the storage rack with some allowance. In other words, taking into consideration the delay of 5 minutes or 10 minutes of the delivery flight 13, allow a little margin for the number of parts boxes left in the storage shelf,
It prevents the lack of parts.

The following equation is an equation for calculating the number N of deliveries by flight. Number of safety stocks M = (Number of boxes collected in the daily allowance) x (Safety stock time) / (Maximum operating time per day) Number of deliveries by flight N = (Number of boxes collected in the daily allowance) / [(Number of boxes stored in shelves)- (Safety stock quantity M)] The safety stock quantity M means that the part is a production line of 1 day.
9 shows how much is used per 9 operating hours, and the safety stock time is the time required for the delivery vehicle 17 to travel around the production line 19 once. For example, when the safety stock time is 25 minutes. The safety stock time is 30 minutes, which is a little longer than the 25 minutes.

In this embodiment, the number M of safety stocks is considered, and the number of storage boxes is obtained by subtracting the number M of safety stocks from the number of shelf storage boxes that can be stored. Then, divide the number of boxes to be delivered in a flight, which is the number of boxes delivered at one time, by the number of boxes to be stored minus the number of safety stocks M from the number of boxes to be stored in the rack.
If the value is below, direct delivery will be applied. At this time, since it is determined by the selected delivery vehicle 17 whether the delivery is divided delivery or direct delivery, parts corresponding to the delivery method of the selected delivery vehicle 17 are extracted. That is, if the selected delivery vehicle 17 is the division delivery, the parts having the value of the number of delivery times N of the courier service larger than 1 are extracted. If the selected delivery vehicle 17 is direct delivery, parts for which the number N of times of delivery by courier delivery is 1 or less are extracted.

Here, taking the record 4a at the top as an example, in the pallet 1 of the record 4a, first, the safety stock quantity M has a maximum operating time of 960 minutes per day and a safety stock time of 30 minutes. , When the number of collection boxes in the daily allowance is 1,
It will be 0.03 boxes. And from 0.03 boxes to 9 shelves
If you divide the number of boxes in the stool box by 0.5 box by dividing the box by 8.97 boxes, you get 0.05 boxes. Number of deliveries for this delivery 0.05
Since the number of boxes is 1 or less, direct delivery is performed, and if the selected delivery vehicle 17 is direct delivery, this part is extracted, and if the selected delivery vehicle 17 is division delivery, this part is targeted. Come off.

In this way, since the boxes were simply transported as much as they could be placed on the storage shelves, they did not know how long the parts would be used in a unit time.
Parts with a large amount of use were quickly lost, and there was a case where the parts were insufficient before the next transportation.However, in the present embodiment, the amount of use of each part per hour is calculated and used. Based on the quantity, it was decided how many times each part should be delivered.

In addition, the number of delivery times N of the flight delivery in step S4
In order to obtain the value, one more field is added to the basic delivery component information, and the value of the number of delivery times N of the flight is entered. Figure 7
It is a figure which shows that the number N of times of delivery by courier was calculated, and one field was added to basic information on delivery parts.

In FIG. 7, a field 71 indicates the number of delivery times N of the courier corresponding to each part.
2 shows the number of delivery times of the part having the largest number of delivery times N of the delivery on the pallet as the representative value N of the number of delivery of the delivery for each pallet. It is possible to process the data for each pallet by indicating the number of delivery times of the part having the largest number of delivery times of the parts on the pallet for each pallet.

In the present embodiment, when determining whether the delivery is divided delivery or direct delivery, the delivery is divided when the number N of flights is greater than 1.01, and the delivery is 1.01 or less. , To improve the accuracy of determining whether each part is direct delivery or split delivery 10
This is because they are looking up to the 1/0's place.

Next, in step S5, if the value of the delivery number N of the flight delivery is larger than 1.01, that is, if it is not placed on a predetermined accommodation shelf in one delivery, the delivery number N of the delivery delivery of the flight delivery is determined in step S6. Sort from top to bottom with the highest value. As described above, when the parts are sorted in the order of the largest value of the number N of times of delivery by courier, that is, the parts which must be delivered many times at first are arranged so that the parts can be allocated first. When the number of delivery vehicles 17 to which parts can be assigned decreases in number, it is possible to prevent parts that cannot be assigned from appearing.

Then, in step S7, the accumulated man-hours, which is the time for handling the parts within one day, is calculated. Each part is 1
The time it takes from the dolly to be placed on the storage rack per day (hereinafter referred to as "parts handling time") is the parts handling time (T1) = (input time) x (the number of boxes in the daily allowance collection box). By accumulating, you can see how much delivery time is completed for all parts per day. That is, it is possible to obtain the time (hereinafter, referred to as accumulated man-hours) from the trolley to the placing on the storage shelf for each part.

Next, in step S8, the time during which the delivery vehicle 17 can work on one day is calculated. Next, the time T2 required for placing the parts of the selected delivery vehicle 17 per day from the trolley to the storage shelf is: T2 = (operating time of delivery vehicle 17 in one day)-[(traveling time) + ( Connection time) + (incidental work time)}.

The working time T2 is calculated by subtracting the running time, the connecting time and the incidental working time from the total operating time of the delivery vehicle 17 in one day. It should be noted that this T2 does not include the time for loading the truck from the delivery lane 16. Further, this T2 is, for example, "time (minutes) 59 that is narrowed down by the total insertion time" in FIG. 5, and is determined when the delivery vehicle 17 is selected.

For example, it is assumed that the working time T2 of the delivery vehicle 13 per day is calculated to be 735 minutes. Then, if the cumulative man-hour T1 is less than 735 minutes, it is a deliverable part, but if the cumulative man-hour T1 is more than 735 minutes, it is a non-deliverable part.

Conventionally, it is not possible to know the daily work amount of the delivery vehicle 17. That is, since the amount of work that can be done by the delivery vehicle 17 in a day is not known within one day of each delivery vehicle 17, the work amount of the delivery vehicle 17 is allocated appropriately per day, so that the work efficiency is very good. There wasn't. For example, if parts cannot be delivered within the specified time, the number of parts that must be delivered is too large to deliver within the specified time, or the number of parts that must be delivered is not large. I didn't know if the work was too slow to deliver within the stipulated time.

As described above, in the related art, the work efficiency is not so good because the work is appropriately allocated without knowing how much work the delivery vehicle 17 can perform in one day. In S7, the time until delivery for each component is calculated, and in Step S8,
By calculating the time that the delivery vehicle 17 can work in one day,
Parts that can be delivered by the delivery vehicle 17 can be specified.

In step S7, the field of the delivery part basic information is increased by one to show the accumulated man-hours.
FIG. 8 is a diagram showing the basic information of delivery parts to which a field of accumulated man-hours is added.

In FIG. 8, reference numeral 81 is a field for displaying the accumulated man-hours, and the parts handling time (T
1) is accumulated. Then, for example, when the possible cargo handling time (T2) of the selected delivery vehicle 17 is 75 minutes, the parts up to the pallet 5 having the accumulated man-hours 51 are the target parts of the selected delivery vehicle 17. The last component 19 in the pallet 6 has a T2 of 75.4 minutes, which exceeds 75 minutes, so that the pallet 6 and subsequent ones are out of scope (cut off).
A broken line in FIG. 8 indicates that a target part and a non-target part are distinguished from each other. A part above the broken line is a target, and a part below the broken line is a non-target (foot cut).

Further, in the field 61 of FIG. 8, the parts below the broken line are displayed as "foot cut" as being out of scope. In this way, the cumulative man-hours are calculated for all the target parts, and the parts whose calculated man-hours do not exceed the possible handling time of the selected delivery vehicle 17 are extracted.

When the parts to be delivered by the selected delivery vehicle 17 have been extracted, next, in step S9, a delivery plan table for delivering the extracted parts to a predetermined storage rack is created. This delivery plan table shows which parts are delivered at what time, and which parts are delivered from what time.

FIG. 9 is a diagram showing a delivery plan table. In FIG. 9, records 9a, 9b, 9c ...
The parts extracted in 4 to step S8 are shown. Further, at the top of each of the fields 91, 92, 93, ..., The number of deliveries, the time to start delivery, and the number of parts boxes delivered for the delivery are shown, and correspond to records. However, the number of boxes is shown. In the last field 135, the total number of boxes delivered by the delivery vehicle 17 is shown at the top, and the total number of boxes is shown at the place corresponding to each record. Also, the shaded area indicates that the delivery of parts is started from here.

Next, a method of allocating the component boxes to be delivered in one day to each delivery service will be described. First, the daily allowance collection box is divided by the daily delivery count to determine how many boxes will be delivered in one delivery. Next, the calculated value is accumulated up to the number of daily deliveries.

Then, if the accumulated value is an integer, the difference between the immediately preceding accumulated value and the next accumulated value becomes the number of delivery boxes for each delivery flight. On the other hand, if the decimal point appears when accumulating, it is necessary to decide whether to round down or round up the decimal point.

Then, the decimal point is rounded down or rounded up to an integer, and the difference between the previous cumulative value and the next cumulative value is set as the number of delivery boxes for each delivery flight. For example, a case where 20 boxes are delivered by all 24 flights will be described. First, 2 boxes of 20
Divide by 4 flights and ask for 0.8 (box / flight). This 0.8
(Box / Ship) is accumulated for each delivery. Here, since the decimal point appears in the cumulative value, round down the cumulative value,
Or round up to an integer.

Table 1 below illustrates the truncation of cumulative values. In addition, Table 2 describes rounding up of cumulative values.

[0085]

[Table 1]

[0086]

[Table 2]

In Table 1, the "cumulative number of boxes" is 0.8,
1.6, 2.4, 3.2, 4.0, 4.8, ...
Since the decimal point is cut off, "cut down" in the lower row
Becomes 0, 1, 2, 3, 4, 4, ... Then, when the difference between the previous value and the next value is calculated in the cumulative number of boxes (“round down” in Table 1) that has become this integer, the “number of deliveries per flight” is 0, 1 , 1, 1, 1, 0, ... And this value is the number of delivery boxes for each flight corresponding to “flight” n, n + 1, n + 2 ,.

Next, in Table 2, the "cumulative number of boxes" is 0.
8, 1.6, 2.4, 3.2, 4.0, 4.8, and so on, since the fractional part is rounded up, "rounding up" in the lower row is 1, 2, 3 4, 4, 5, ... And
When the difference between the previous value and the next value is calculated for the cumulative number of boxes (“rounding up” in Table 2) that has become this integer, the “number of deliveries per flight” is 1, 1, 1 1, 0, 1, ..., And the value of this difference is the number of delivery boxes for each flight corresponding to “flight” n, n + 1, n + 2 ,.

In this embodiment, rounding down is adopted. In this way, the daily allowance collection box number is divided by the daily allowance delivery count, and the value is accumulated so as to correspond to the daily allowance delivery count, and the decimal points are rounded down or rounded up to an integer value, and then adjusted. A delivery plan table is created using the value of the difference between the numerical value and the immediately preceding value as the number of delivery boxes for each delivery flight.

With this delivery plan table, it is possible to indicate at what time and at what time of delivery what part and how many parts will be delivered. Next, in step S10, a delivery plan graph is created based on the delivery plan table created in step S9. This delivery plan graph shows how much time the selected delivery vehicle 17 spends for each delivery operation.

FIG. 10 is a diagram showing a delivery plan graph.
In FIG. 10, the horizontal axis represents the number of the delivery flight indicating one delivery of the component, which corresponds to the number of deliveries in FIG. 9. The vertical axis indicates the time required for each delivery. A vertical bar graph shows how long each delivery takes to deliver. The thick line shows the ideal delivery (time) interval, and in the present embodiment, a plan is made to deliver at 25-minute intervals.

As shown in FIG. 10, the time required for each delivery flight is calculated by adding the traveling time, the connection time, and the cargo handling time required for placing the parts on the storage rack. By creating this delivery plan graph, it is possible to compare the ideal time required for delivery of one flight and the time required for actual delivery of one flight. That is, the closer the tip of the bar graph, which is the actual delivery time, to the ideal delivery (time) interval indicated by the thick line, the closer to the ideal delivery (time) interval, and the top of the bar graph. Is away from the thick line, the actual delivery time is longer than the ideal delivery (time) interval, or
It indicates that the actual delivery time is shorter than the ideal delivery (time) interval.

Next, in step S11, leveling is performed to reduce the error between the ideal delivery time for one flight and the actual delivery time for one flight. This error in the delivery time basically means that if the times when the deliveries 13 arrive, the number of boxes of the deliveries at that time increases,
Delivery time is getting longer. Further, at a time when the number of deliveries 13 is small, the delivery time is short because the number of boxes of the delivery flights at that time is small. As described above, the error of the delivery time is related to the arrival time of the delivery flight 13.

In order to reduce the error in the delivery time, it is necessary to allocate each component box to each delivery flight so that the number of delivery boxes does not concentrate on a certain delivery flight. In other words, by allocating the parts box of the delivery flight with a long delivery time to the delivery flight with a short delivery time, the error in delivery time can be reduced,
Specifically, the delivery flight that starts delivery is shifted to the later delivery flight to reduce the error in delivery time.

Next, a leveling method for reducing the error in the delivery time will be described. First, for each part, the value obtained by dividing the daily allowance collection box number by the daily allowance delivery count is 3
There are two cases. The first case classification is a case where a value obtained by dividing the number of daily allowance collection boxes by the daily delivery number is larger than 2. Since the parts box is almost uniformly allocated to each delivery flight for this part, it is not necessary to move the allocated parts box to another delivery flight. For example, in the delivery plan table of FIG. 9, the pallet 23 of the record 9a has 120 boxes of parts delivered per day, and 120 boxes are 44 boxes.
When divided by stool, it becomes 2.7 boxes. Since it is 2.7 boxes per flight, it can be seen that a relatively large number of boxes are uniformly allocated to almost all flights, and it is excluded from the leveling target.

The second case is a case where the value obtained by dividing the number of daily allowance collection boxes by the daily allowance delivery number is larger than 1 and smaller than 2. In this component, the component boxes are almost uniformly assigned to each delivery flight, but there is room for moving a delivery with a large number of component boxes to another delivery flight. For example,
In the delivery plan table of FIG. 9, pallet 4 of record 9g
In No. 4, the number of parts delivered per day is 60, and if this 60 is divided by 44 flights, it becomes 1.3. Since 1.3 boxes per flight, it can be seen that parts boxes are almost evenly assigned to each delivery flight. However, 1.3 boxes per flight can be moved to another delivery, ie 1.3
Since the number of delivery boxes for each flight can be changed depending on whether one box is viewed as one box or two boxes, it is a target for leveling.

The third case is when the value obtained by dividing the number of daily allowance collection boxes by the daily allowance delivery number is smaller than 1. As for this component, the component box may be moved to another flight because it is sufficient that some of the flights deliver the component. For example, in the delivery plan table of FIG. 9, the pallet 52 of the record i has seven boxes of parts to be delivered per day, and if this seven boxes are divided by 44 flights, it becomes 0.1 boxes. Since it is 0.1 box per flight, it can be seen that 1 box is assigned to 10 flights, and it can be assigned to any of 10 flights. That is, it is the target of leveling.

Then, for the second and third cases, the delivery flight for starting delivery is shifted to the later delivery. For the second case, the value obtained by dividing the number of daily allowance collection boxes by the daily allowance delivery count is cut off, and the starting delivery service is shifted to the next delivery service. Further, for the third case classification, the movement range of the start delivery flight is specified, the man-hours of the delivery flight that can be considered by all the allocation of the movable range are calculated, and the calculated man-hour is the minimum. Calculate the value and maximum value, and use the one with the smallest value obtained by subtracting the minimum value from the maximum value.

In the above description, the value obtained by subtracting the minimum value from the maximum value of the calculated man-hours is the smallest, but the difference between the maximum man-hour value and the minimum man-hour value is less than the predetermined value. May be adopted. Further, when the man-hours of the delivery plan table are leveled, it is possible to move the delivery service that started to a delivery service to the rear by a human operation.

As a result, the number of parts to be delivered out of one delivery day of the delivery vehicle is large in some delivery flights and few in some delivery flights, and the delivery workload is leveled. It becomes possible. Further, since each part is delivered shortly after the time when it is delivered, it is possible to sufficiently cope with a sudden change in the delivery plan.

Next, in step S12, a delivery tag is created. This delivery card shows the parts of the delivery schedule arranged in the order of the storage shelves that the delivery vehicle 17 passes through when passing through the production line 19. FIG. 11 (a) is a diagram showing a delivery tag, and FIG. 11 (b) shows the position (address) of the storage shelf.

In FIG. 11 (a), the delivery tag 111 includes a column 112 indicating which delivery vehicle 17, a column 113 indicating the number of deliveries, a column 114 indicating delivery time, and which parts. Column 115 indicating how many boxes are to be placed in the storage shelves
And a column 116 for indicating the number of the truck to which the delivery vehicle 17 pulls.

Further, in FIG. 11 (b), 117 indicates each address of the storage rack, and the arrow indicates the production line 18. A delivery order table corresponding to the order in which the addresses are arranged is created, and the column 115 of the delivery tag 111 is based on the delivery order table.
And the order of the columns 116 is changed.

FIG. 12 is a flow chart for creating a delivery ticket. First, in step ST1, the delivery plan table and the delivery order table are read. Next, step S
At T2, the parts of the delivery plan table are rearranged in the order of the addresses of the delivery order table in association with the addresses of the parts of the delivery plan table and the addresses of the delivery order table.

Next, in step ST3, parts are allocated to each dolly. In the present embodiment, the number of carts to be pulled by the delivery vehicle 13 is 5, and up to 15 boxes can be loaded per cart. For example, in the delivery tag 111 of FIG. 11A, 12 boxes from the parts 3 to 211 are attached to the truck number 1, and 13 of the parts 77 are attached to the truck number 2.
It is shown that 11 boxes of parts 23 are mounted on the trolley number 3, 5 boxes of components 99 to 200 are mounted on the trolley number 4, and 11 boxes of components 290 to 98 are mounted on the trolley number 5. ing.

Then, in step ST4, each delivery flight is output to the output format of the delivery tag 111 as shown in FIG. The delivery tag 111 may output the number of deliveries on paper for each delivery vehicle 17, or the delivery vehicle 1
If 7 has a display screen capable of outputting the format output in step ST8, the display screen may be output. Parts are delivered while looking at the delivery tag 111.

Next, in step S13, a split bill is created. This split bill shows the parts of the delivery bill 111 created in step S12 rearranged based on the position of the delivery lane 16. FIG. 13A is a diagram showing the split bill, and FIG. 13B shows the position of the delivery lane 16.

In FIG. 13A, the divided bill 131 has a column 132 indicating the number of deliveries and a column 13 indicating the delivery time.
3, a field 134 showing the time when the parts box is placed on the dolly from the delivery lane 16, a field 135 showing how many parts are to be placed in the storage shelves of which address, and a trolley number to which the delivery vehicle 17 pulls The column 136 and the like are included. The split bill 131 is obtained by rearranging the parts arranged in the delivery ticket 111 in the order of the trolley numbers into the order of the parts arranged in the delivery lane 16. That is, the parts are rearranged in the order in which the parts are placed on each carriage.

Further, in FIG. 13B, 137 indicates the positions of the parts lined up in the delivery lane 16, and the arrow indicates the delivery vehicle 1
Reference numeral 7 indicates a line moving on the delivery lane 16. A delivery order table corresponding to the order in which the parts are arranged in the delivery lane 16 is created, and the parts of the delivery tag 111 are rearranged based on this delivery order table.

FIG. 14 is a flow chart for creating a split bill. First, in step STP1, the delivery plan table and the delivery order table are read. Next, in step STP2, the parts of the delivery plan table are rearranged in the order of the addresses of the delivery plan table in association with the addresses of the parts of the delivery plan table and the addresses of the delivery order table.

Next, in step STP3, parts are allocated to each dolly. The process up to this point is the same as the process of creating the delivery tag 111. In the case of direct delivery, parts are handled in pallet units, so only the delivery tag 111 showing the pallet name need be created. That is, in the case of direct delivery, only the step of creating the delivery tag 111 is required.

Next, in step STP4, the delivery order table is read. Then, in step STP5, the parts arranged in the delivery order are rearranged in the order corresponding to the delivery order table. Finally, step STP6
In the case of the delivery tag 1 as shown in FIG.
Output to the output format 11 and end.

This divisional bill 131 may output the number of deliveries for each delivery vehicle 17 on paper, or may be provided with a display screen capable of outputting the format output in step ST8 to the delivery vehicle 17. , May be output to the display screen. While looking at the split bill 131, each component is placed on each trolley.

Then, in step S14, it is determined whether the delivery vehicle 17 selected in step S2 is the last delivery vehicle 17 that can be selected. When it is determined in step S14 that the vehicle is the final delivery vehicle 17 (step S1
4 is Yes), the delivery planning system ends.

On the other hand, in step S14, the final delivery vehicle 17
Is not determined (step S14 is N
o), returning to step S2, the next delivery vehicle 17 is selected.
In this flow, in step S14, it is determined whether or not the delivery vehicle 17 is the last vehicle. However, this flow also ends when all the parts of the delivery part basic information are assigned. Therefore, in the fourth delivery vehicle 17 out of the five delivery vehicles 17, when all the components have been allocated, the fourth delivery vehicle 17 ends.

If the number of delivery times N of the courier is lower than 1.01 in step S5, that is, if the parts can be delivered at one time, in step S15, the delivery part basic information is sorted in descending order of the number of divisions. Line up from the top.
The steps of direct delivery from step S15 to step S21 include steps S6 to S13 described above.
The process is almost the same as the process of divided delivery up to. In the process of direct delivery, only the delivery ticket needs to be created, and the split ticket is not required to be created.

In the above embodiment, step S1
In Fig. 3, when allocating the component boxes to each trolley, the maximum number of boxes to be loaded was determined in advance, and the component boxes were allocated within that range. Alternatively, the component boxes may be assigned to the truck within the range of the volume value.

Further, in the recording device of the delivery planning server 20, each data stored is basically created in advance, and there is a correction part or a new addition part for each data. The data is input as appropriate and each data is changed. However, a part or all of each data is received from the transmission control unit via a transmission medium such as a network line from another server or client. It may be configured to.

[0119]

As described above, according to the parts delivery plan creation method and the parts delivery plan creation device of the present invention, the parts that can be loaded on each trolley for loading the parts to be pulled by the delivery vehicle by, for example, a computer. Since the parts are assigned to the respective carts in the order of delivery based on the number, the time required to create a delivery plan can be shortened and the parts can be efficiently and reliably delivered to the delivery place.
