Description

  In the present invention, from the viewpoint of increasing the effective utilization or operation rate of each device, device priority is assigned to a usable device used in each process for producing a product including parts and semi-finished products, work and other necessary processes. The present invention relates to an order adjustment system, an apparatus priority order adjustment method, and a program.

  When producing products that meet demand, work, and other necessary processing, supply objects (production lots, inventory on hand, etc.) are allocated to demand objects (product demand, safety stock, etc.), and the actual supply and demand of products that are actually required After the balancing process to make a plan, improve the production availability of the equipment or equalize the availability of each equipment based on various attributes related to product production, work and other necessary processing such as product type, process, lot number, etc. From the viewpoint of realizing the above, it is performed to selectively allocate to a usable device among a plurality of devices.

  Conventionally, when assigning priorities selectively to, for example, available devices for each process from among a plurality of devices based on the product type, process, number of lots, etc. as described above, several device priority assignment methods Is considered.

(1) One device priority assignment method is the assignment of the priorities of usable devices used for each type α, β, γ and for each process, and the plan creator assigns the types α, β, γ. Since the usable devices are different for each, the priority order of the usable devices is determined in consideration of the types α, β, γ and the usable devices used for each process.

  Specifically, as shown in FIG. 12, in the case of processing related to the product type α, the devices B1 to B5 are all usable devices, and in the case of processing related to the product type β, only the device B1 is a usable device. In the case of the processing related to the product type γ, if the devices B1 and B2 are usable devices, first focus on the product type β having the smallest usable device, and the device B1 has the highest priority for the product type β. “1” is assigned, and then the two devices B1 and B2 are usable devices in the product type γ. However, since the device B1 has already been assigned the priority “1” in the product type β, the device B2 is assigned to the device B2. The priority “1” is assigned, and the priority “2” is assigned to the device B1. Finally, since any device B1 to B5 can be used in the product α, the priority “1” is assigned to the devices B3 to B5 except for the devices B1 and B2, and the priority “2” is assigned to the device 2. Since the device B1 is a device that is absolutely necessary for the product type β, the lowest priority “3” is assigned.

  Therefore, as described above, priority is assigned to the devices B1 to B5 while considering the relationship among the varieties α, β, and γ, so that the available devices B1 to B5 can be effectively used without duplication. It is possible to execute necessary processes for each of the products α, β, and γ without delay.

  On the contrary, regarding the product type α, if it is determined that any device B1 to B5 can be used and the priority “1” is assigned to the device B2, the device B2 cannot be used with the product type γ. It must be used. As a result, there is a case where the device B1 used for the production of the product β is not available and the production of the product β is delayed.

(2) Another method for assigning device priorities, as shown in FIG. 13, relates to the processing of the varieties α, β, γ, and is divided into a plurality of steps 1 to 3, and a plurality of usable devices B1 to B5. In this case, the devices B1 to B5 are considered in consideration of the relationship between the varieties α, β and γ and the usable devices B1 to B5 and C1 for each of the steps 1 to 3. , C1 is assigned a priority.

(3) Furthermore, as a processing order control method similar to the allocation of device priority, the number of in-process devices is calculated in advance from the processing capacity of each device, and lots are assigned to each device so that the number of in-process devices is always appropriate. When multiple lots are processed at the same time, if more than the number of in-process lots remain in one manufacturing device, the entire lot distribution is fixed by distributing the processing to other manufacturing devices. It is the method of moving at the speed of. In addition, each manufacturing apparatus is provided with a signal device that displays a color according to the in-process level of the lot, and the pre-process of the manufacturing apparatus is a method of processing the lot while confirming the display color of the signal device in the subsequent process (Patent Document 1). ).
JP 2001-228912 A

  Therefore, among the device priority assignment methods as described above, in the device priority assignment method of (1), assignment of priorities for processing each kind α, β, γ in one process. However, considering the allocation based on the assumption that only one unit can be used in one process, the mutual relationship among multiple varieties α, β, and γ is taken into consideration even when assigning priorities manually. However, it is possible to assign priorities to the devices B1 to B5.

  However, in practice, when a process related to a certain product type is performed, it is rare to complete production, work, and other processes in only one process, and many of them span a plurality of processes 1 to 3 as shown in FIG. In general, a plurality of apparatuses B1 to B5 and C1 are used, and the process is performed while increasing the operating rate of the apparatus.

  Therefore, when processing a plurality of varieties α, β, and γ across a plurality of processes in this way, while grasping devices that can be used for each of the varieties α, β, and γ and for each process 1, 2, 3, Since the priorities are assigned to the devices B1 to B5 and C1, it is very difficult to artificially assign the priorities to the devices that can be used while considering the devices that can be used among the products and between the processes. . That is, as shown in FIG. 13, when setting the priorities to the devices B1 to B5 and C1 in consideration of the varieties α, β, and γ and over a plurality of steps 1 to 3, manual setting by the planner is performed. As the number of varieties, processes, and usable devices increases, it becomes difficult to incorporate fluctuations in the supply and demand situation. Therefore, dynamic adjustment of priority for each device cannot be performed.

Further, the technique of the prior art document 1 according to (3) described above is a method for determining the number of in-process devices for each device, and replenishing each device with the lot so that the number of in-process devices is always appropriate. There is a system that distributes the processing to other manufacturing devices while considering the progress of the processing, because the processing waiting time becomes longer when there are more than the number of in-process lots remaining in one manufacturing device, multiple varieties and each of the plurality of varieties while determining the usable device processes contemplated by the present invention, different from those in the available device will assign a priority for each process.

  The present invention has been made in view of the above circumstances, and a device priority adjustment system and device priority adjustment that dynamically and automatically adjust the priority of each usable device used in each process of processing each product type. An object is to provide a method and a program.

(1) In order to solve the above-mentioned problem, a plurality of target varieties may be obtained by using a plurality of usable devices including the same type of device between a plurality of target varieties and before and after the process across a plurality of processes . In the device priority order adjustment system that assigns priorities to usable devices for each process when performing processing, a product quantity calculating means for calculating the total amount of each target product type from demand information including the target product type, and this product type quantity and average load calculating means for calculating a mean load of each available device from the total load required in each step obtained from the total quantity of each target type obtained by the calculating means and the number of available apparatus used in each step, the Individual device load for determining the total load required for all target product types and all processes of each usable device based on the average load of each usable device in each step obtained by the average load calculating means Priority that assigns a high priority to each usable device in order of decreasing total load for each target product type and each process based on the relationship between the state judging means and the total load of each usable device obtained by this judging means It is the structure which provided the order | rank determination means.

  With this configuration, the total load required for each process of the individual device is obtained from the total load required for each process obtained from the total amount of each target product, and for each target product and each process. Since the highest priority is assigned in ascending order of the total load of each usable device, the priority can be assigned while dynamically responding to changes in the load state.

In addition, when assigning priorities to devices that can be used for each process of a plurality of target varieties, the total amount of each target varieties is previously extracted from the demand information, and at least the process flow required for the corresponding varieties from each target varieties, This setting can be made by creating and setting the link configuration so as to extract the necessary load with the necessary steps in the process flow, the usable device group necessary in this step, and the necessary device information in this usable device group. has been using the linking link structure, the calculated total quantity of each target type from the demand information and the set linkage links from the total quantity of each target type determined including each target type using the configuration, all subjects varieties and after obtaining the total load for the entire step, based on the magnitude relationship between the total load of each available apparatus, each target type and per each step of each available device In addition, since the highest priority is assigned to each usable device in the order of the smallest total load, the priority can be automatically assigned to each usable device regardless of the number of target products, number of processes, and usable devices. Is possible.

(2) The device priority order adjustment method according to the present invention calculates the average load of each usable device from the total load required in each step of each target product and the number of usable devices used in each step, and by this calculation, After obtaining the total load required for all target varieties and all processes of each usable device based on the average load of each usable device in each obtained process, based on the magnitude relationship of the total load of each usable device, By assigning a high priority to each usable device in order of decreasing total load for each target product and each process, a priority is assigned according to the total load of each usable device for each target product and each process. It becomes possible to adjust dynamically.

  It should be noted that the total amount of each target product type is previously extracted from the demand information, and at least the process flow required for the product type from each target product type, the processes required in this process flow, the usable device group required in this process, and the use possible If a link configuration linked so as to extract the necessary load with the required device information in the device group is set, the total amount of each target product type is extracted from the demand information using this linked link configuration. Also, from each target product type, at least the process flow required for the product type, the process required by this process flow, the usable device group necessary for this process, and the necessary device information necessary for this usable device group are extracted. In this case, the total amount of each target product type is extracted from the demand information, and finally, in order of priority according to the total load of each usable device for each target product type and each process. It is possible to automatically assign the.

(3) If a program that is a series of processing procedures of the system as described above is stored in advance in a readable manner in a storage medium, and read and executed by the CPU, it can be realized by the program. Become.

  The present invention can provide a device priority order adjustment system, a device priority order adjustment method, and a program capable of dynamically and automatically adjusting the priority order of each usable device used in each process.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 are diagrams for explaining an embodiment of a device priority order adjustment method according to the present invention.

  When producing products of various varieties that meet demand, supply objects (production lots, inventory on hand, etc.) are allocated to demand objects (product demand, safety stock, etc.) as described above, and the actual supply and demand of products that are actually required After carrying out the balancing process to create a plan, it is possible to move from multiple devices based on various attributes related to the production, work, and other necessary processes such as parts, intermediate products, etc. The priority order of usable devices is adjusted while taking into consideration the various factors.

(1) Prior to the dynamic adjustment of the device priority order, as a pre-processing stage, for example, as shown in FIG. (Including quantity) is linked to each type information from the demand information that is object information, and device information (load and performance of each device) from the type information that is object information as shown in FIG. An object linking setting process linked to take out is performed.

  That is, in the association setting from demand information to each type information, demand information including the type and the type ID are linked, and as shown in FIG. 3B, demand A which is demand information as the required quantity of each type. Are input so as to obtain, for example, the total number of lots for each product type through the product type ID, and the total number of lots for each product type is extracted and stored in the main storage device of the device priority order adjustment system. Therefore, by using the linked configuration as shown in FIG. 3A, the kind α: total lot quantity 100, kind β: total lot quantity 20, Variety γ: Total lot quantity 20 can be taken out.

  On the other hand, the link setting for reading the device information from the product information links each product information and the process flow information ID in order to find the necessary process flow information (object) in each product information. Are linked to the process flow information via the process flow information ID. Similarly, in order to find out necessary process information (object) from this process flow information, each process flow information and process information ID are linked, and each process flow information is linked to the process information via the process information ID. To do. Furthermore, in order to find out the necessary device group information (object) from this process information, each process information and device group information ID are linked, and each process information is linked to the device group information via the device group information ID. To do. Furthermore, in order to find out the necessary device information (object) from this device group information, each device group information and device information ID are linked, and each device information, that is, a device, is connected via the device information ID for each device group information. For example, load information (including performance information) of the apparatus for dynamically adjusting the priority order is taken out. Accordingly, here, a link configuration of object information linked in order to extract device information from each type information is created in advance and stored in the main storage device of the device priority order adjustment system.

(2) Next, after performing the object association setting process as described above, the apparatus priority order is dynamically adjusted. Specifically, as shown in FIG. 1, an average load calculation process for obtaining an average load of each process for each type is performed. This average load calculation process calculates the load (the total number of tickets (capability assigned to lots of each process) or the number of processing times) for each process from each type information, and calculates the calculation result. Divide by the number of devices in each process and the number of days (planned period) to determine the average load of each usable device in each process. However, it is assumed that the planned period is 1.0 and half day is 0.5. In the example of FIG. 1, in order to facilitate understanding, if the planning period is one day, the average load of each usable device is obtained by dividing the load for each process by the number of usable devices in the process. be able to.

  Incidentally, in FIG. 1, it is assumed that the capacity of one lot and one ticket is consumed, and when processing 100 lots for the type (type information) α, 20 lots for the type β, and 20 lots for the type γ, Since there are five usable devices B1 to B5, the average load of each usable device B1 to B5 with respect to a processing capacity of 100 lots is “20”, and in Step 2, the usable devices are B1 and B2, The average load is “50”.

  Similarly, in the process 1 relating to the product type β, the usable apparatus is one B1, and the processing capacity of 20 lots is processed by one. Therefore, the average load of the apparatus B1 is “20”, and the apparatus usable in the process 2 is also available. Is one of B1, and the average load of the device B1 is “20”.

  Furthermore, in the process 1 and the process 2 related to the product type γ, two usable devices B1 and B2 are processed, and the processing capacity of 20 lots is processed by two, so that both the process 1 and the process 2 can use the usable devices B1 and B2. The average load is “10”.

(3) Subsequently, as the dynamic adjustment of the device priority order, the load state of the individual device for determining the average load of the individual devices over all the processes is determined from the average load of each device of each process obtained as described above. .

Device B1 = (product α process 1 load) 20+ (product α process 2 load) 50
(Variety β process 1 load) 20 + (variety β process 2 load) 20
(Variety γ process 1 load) 10+ (variety β process 2 load) 10 = 130
Device B2 = (product α process 1 load) 20+ (product α process 2 load) 50
(Variety γ process 1 load) 10+ (variety β process 2 load) 10 = 90
Device B3 = (variety α process 1 load) 20
Device B4 = (variety α process 1 load) 20
Device B5 = (variety α process 1 load) 20
Therefore, it can be seen that among the average loads of the individual devices B1 to B5, the devices with the smallest loads are the devices B3, B4, and B5, and the devices with the next smallest loads are the devices B2 and the devices B1 with the largest loads. .

(4) Therefore, as the dynamic adjustment of the device priority, the priority is determined from the average load of the individual devices described above.

  This priority order is determined by comparing the load relationships of the devices for each process in the processing of the varieties α, β, γ, and setting the device with the smallest load as the priority “1”, and conversely the largest load. Set the lowest priority for the device. Incidentally, in the process 1 of the product type α, since the relationship of the devices B3 to B5 (20) <device 2 (90) <device 3 (130) is satisfied, the devices B3 to B5 (20) → priority “1”, device 2 (90) → Priority order “2”, Device 3 (130) → Priority order “3”. In the process 1 of the product type β, since only the device B1 is used, the priority order is “1” regardless of the load state. In the process 1 of the product type γ, since the relationship of device 2 (90) <device 3 (130) is established, device 2 (90) → priority “1” and device 3 (130) → priority “2”.

  Similarly, in the process 2 of the products α, β, and γ, the magnitude relationship is determined, and the priority of the device having a small load is set large.

  The series of processes as described above is based on the link configuration of various objects linked by the computer based on the requested quantity of each product type by the plan creator and stored in the main storage device by the link setting process. (2) calculate the average load, (3) determine the total load of the individual devices, and (4) finally determine the priority order.

  Therefore, according to the embodiment as described above, the priority order is automatically assigned to the usable devices for each process of each product type while considering the load state of the capability of the device among a plurality of devices. Therefore, even when processing many types of products, it is possible to quickly determine priorities by calculating the load status of each device, etc., and taking into account fluctuations in demand conditions over time Can be determined.

  FIG. 5 is a block diagram showing an embodiment of an apparatus priority level adjustment system according to the present invention to which the above apparatus priority level adjustment method is applied.

  This apparatus priority order adjustment system includes input information such as demand information in FIG. 3A, object information related to product type information, product information, process flow information, process information, device group information, device information,... Information input means 1 such as a pointing device such as a keyboard or a mouse for inputting object information relating to, demand information which is a required quantity of each product type in FIG. 3B, control instruction information including activation and various other necessary information A data buffer storage unit 2 that is an external storage device that temporarily stores object information and the like input by the information input unit 1 and temporarily stores data in the middle of processing and processing result information; and at least the information input unit The object information stored in the data buffer storage unit 2 is read from 1 and displayed, and each product is determined from the demand information. In order to adjust the device priority order, the operation screen display means 3 for creating a linked link configuration while checking the object linking information for extracting the device lot information from each type of product information Of a plurality of usable devices used in each process required for each product type based on a recording medium 4 storing the program and a device priority adjustment program stored in the recording medium 4 An output unit 7 including a priority adjustment processing unit 5 constituted by a CPU that performs adjustment, a main storage device 6, the operation screen display unit 3 described above, and a printer or the like is further provided.

  The process flow information input from the information input means 1 is definition information such as how each kind flows and how each process is combined. The process information is combined with the process flow information. The device group information is the definition information about which usable devices are configured for each process, and the device information is the definition information about the processing content of each device itself. Examples include load information and performance information.

  As shown in FIG. 3, the priority order adjustment processing unit 5 extracts each kind information from the demand information in order to derive the total lot quantity for each kind based on the requested quantity of each kind inputted as needed. As shown in FIG. 4, in order to extract device information (such as the load and performance of each device) from the product type information, the linked configuration data shown in FIGS. 3A and 4 is created and stored in the main storage device 6. Based on the object association setting means 51 to be set and the demands A to H in FIG. 3B input from the information input means 1, the association shown in FIG. 3A and FIG. Using the attached link configuration data, the priority is automatically assigned to the devices that can be used for each product type and for each process, based on the load and capacity of each device. Loading processing means 52 When the loading processing means 52 assigns priorities to the devices that can be used for each product type and each process, the input quantity or the delivery quantity is bucketed under the specified constraint conditions (capability, member restrictions, etc.). Scheduling processing means 53 is provided that creates a schedule that predicts on the unit time axis and sets the input date so that the amount of product to be delivered is completed at least on the delivery date.

  As the object association setting means 51, the object information stored in the data buffer storage unit 2 from the information input means 1 is displayed on the operation screen display means 3, and the total quantity (total lot quantity) of each product type is extracted from the demand information. As described above, the product ID is linked from the demand information, the total number (total lot quantity) of each product is linked so as to be taken out, and after confirmation, it is set in the main storage device 6. Similarly, using the operation screen display means 3, process flow information from each type information shown in FIG. 4 which is each object information for extracting device information from each type information, process information from this process flow information, A link configuration is created while linking so as to extract device group information from each process information and device information from each device group information. After confirmation, the link configuration is similarly set in the main storage device 6.

  Note that the link configuration linked from the product information to the device information shown in FIG. 4 has n pieces of process flow information linked to one product information as shown in FIG. Each process flow information necessary for each process is linked to a process flow information ID and branched. Accordingly, since one piece of process flow information linked to the necessary process flow information ID in one kind of product information is linked to n pieces of lower order process information, it is necessary for each piece of process flow information. The process information ID for each process information is linked and branched.

  Hereinafter, the same applies to process information and device group information. Here, load information / performance information of each device, which is device information, is extracted as final information, but when extracting information other than device information, It becomes the structure which links other information to lower order through ID of device information.

  As the loading processing means 52, for example, a linked link structure shown in FIG. 3A is used, and the total amount for each type is determined based on the required quantity of each type inputted as shown in FIG. 3B. Product quantity calculation means 52A for extracting the number of lots (including the total amount), and the number of loads (total tickets for each product (capability assigned to lots of each process)) or processing time, which is the device information described above for each process from each product information The average load calculating means 52B calculates the average load of each usable device for each process as shown in FIG. 1 by dividing the calculation result by the number of devices in each process and the number of days (planned period). The individual device load state determination means 52C for obtaining the average load of the individual devices over the entire process from the average load of each device in each step obtained by the average load calculation means 52B, this individual device load state Compare the magnitude relationship of the load of each device for each process determined by the disconnecting means 52C, set the device with the smallest load as the priority “1”, and conversely set the device with the largest load as the lowest priority. Priority order determining means 52D is provided.

  Next, the operation of the apparatus priority order adjustment system as described above and a series of processing examples by the program according to the present invention will be described with reference to FIG. Prior to the dynamic adjustment of the device priority order, necessary object information is input in advance from the information input means 1 and expanded on the operation screen display means 3, and the object information and the object information as shown in FIGS. The next object information ID is linked, the object information and the object information are linked, and set in the main storage device 6 (object linking setting means).

  In the state as described above, when the device priority order adjustment system receives the operation start signal from the information input means 1, the priority order adjustment processing unit 5 reads the device priority order adjustment program stored in the recording medium 4. Are stored in the data buffer storage unit 2 and necessary processing is executed based on the program.

  That is, the priority order adjustment processing unit 5 receives the demand information of the demands A to H as shown in FIG. 3B from the information input unit 1 and stores them in the main storage device 6 as shown in FIG. Since the demands A to D are linked to the same product information, that is, the product α, from the product IDs of the demands A to H, the lot of the product α is used. The numbers are totaled to obtain the product type α = total lot number 100. Similarly, product type β = total lot number 20 and product type γ = total lot number 20 are calculated (S1: product quantity calculation means 52A, product quantity calculation function).

  Therefore, based on the product type α100 lot, product type β20 lot, product type γ20 lot shown in FIG. 1 calculated as described above, the device information from the product information shown in FIGS. 4 and 6 already stored in the main storage device 6 is obtained. The average load of the apparatus which can be used for every kind and every process is calculated using the linked link structure which takes out (S2: average load calculating means 52B, average load calculating function). In the average load calculation process of the usable device, first, process flow information defining what process is associated with the process flow information ID linked to the product type α is extracted. Thereafter, process information (process 1: refer to FIG. 6) defined in the process contents of each process linked to the process information ID linked to the process flow information is extracted. Further, the device group information ID linked to the process information + the load (for example, processing time information) corresponding to the type α100 lot required in the process is calculated and used in the process linked to the device group information ID. Device group information is obtained, the load is divided by the device group information (number of devices that can be used in the process), the average load of each device is calculated, the product α100 lot, process information (process 1), device group information ( Device B1 to B5), the average load 20 of each device, and information related to the device information ID linked to the device group information are stored in the data buffer storage unit 2.

  Subsequently, with respect to the type α100 lot, using the linked link configuration, the process information (process 2: see FIG. 6) is extracted from the next process flow information ID, and similarly, the apparatus group information (apparatus B1, B2), The average load 50 of the apparatus and the apparatus information ID linked to the apparatus group information are taken out, and the product type α100 lot, process information (process 2), apparatus group information (apparatus B1, B2), the average load 50 of each apparatus and the apparatus The device information ID linked to the group information is acquired and stored in the data buffer storage unit 2 in the same manner.

  Further, for the product type β20 lot and the product type γ20, necessary information is extracted and stored in the data buffer storage unit 2 using the linked link configuration.

  Next, after determining the average load of each usable device for each product type and each process as described above, the priority order adjustment processing unit 5 calculates the total load of the individual device (S3: individual device load state) Determination means 52C, device load state determination function). The specific processing here is step 1 relating to the device information (device B1) taken out from the device information ID stored in the buffer storage unit 2 and stored in the data buffer storage unit 2. The total load is calculated by sequentially adding the average loads in step 2. As a result, as shown in FIG. 8, the device B1 information, which is each device information used in step 1, is the total load 130, the device B2 information is the total load 90, the device B3 information is the total load 20, and the device B4 information. The total load 20 is obtained, and the total load 20 is obtained for the device B5 information. Further, the total load 130 is obtained for the device B1 information, which is each piece of device information used in the process 2, and the total load 90 is obtained for the device B2 information.

  Furthermore, when the priority order adjustment processing unit 5 obtains the total load of each of the usable devices B1 to B5, it sets the usable devices of each process and the corresponding process as a set, and total load information of all the processes of each device. .. Are sorted in ascending order, and for example, integer sequential numbers 1, 2,..., Which are assigned from the highest priority to the lowest priority, are assigned in ascending order of the total load of the available devices, and the sets of devices having the same total load are assigned. (S4: priority determining means 52D, priority determining function).

  The loading processing means 52 assigns priorities to the available devices for each product type and for each process, and then relates to product input and product completion including processes for production, work and other processing of each product type. A schedule is planned. This schedule is planned by the scheduling processing means 53.

  This scheduling processing means 53 predicts the input quantity or the payout quantity on the time axis in units of buckets under the specified constraint conditions (capability, member restrictions, etc.). For example, as shown in FIG. Based on the work schedule, the standard work schedule, and the allowable work schedule, scheduling is executed by one of the following two methods or a combination thereof. Here, the theoretical work period is the minimum time that is theoretically known to be necessary for processing, and is represented by the theoretical work period = the minimum required time until the start of processing + resource occupation time + post-processing time. The standard work period is a standard processing time, and is represented by standard work period = theoretical work period × standard work period coefficient. The allowable work period is the maximum allowable time that can be moved forward, and is expressed by allowable work period = theoretical work period × allowable work period coefficient.

  * Scheduling method 1: Forward development from the date of introduction (see FIG. 10).

This scheduling method is an example in which a provisional introduction date is determined retroactively from the product delivery date based on the standard work schedule, and forward development is performed from this introduction date. In the figure, (a) is the date of entry from the delivery date back to the standard work schedule. In (b), forward development is performed in the theoretical construction period, and resource occupancy time is piled up and crushed. The stacking / disintegration of resource occupancy time is the last when the capacity load of a certain process exceeds the specified capacity load. The process will be postponed or moved forward within a range not exceeding the predetermined capacity load. In (c), when the development result is completed earlier than the delivery date, the scheduled completion date is set as the delivery date. Therefore, (c) is a marginal buffer.
In addition, when the input date which goes back in the above (a) becomes past from the plan start date, this plan start date is set as the input date.

  * Scheduling method 2: Backward development from product delivery date (see FIG. 11).

This scheduling method is an example of Backward expansion from product delivery date. In the figure, (a) performs Backward development in the theoretical work period from the delivery date, and piles up / downs the resource occupation time.
