[Background and outline of this embodiment]
In batch processing equipment that processes multiple products at once, there are restrictions that should be taken into consideration when formulating a production plan, such as whether or not they can be combined in the same batch and equipment capacity, compared to equipment that processes a single product at once. A wide variety. In addition to considering these restrictions, it is a very difficult problem to formulate a production plan while also considering the customer delivery date and the processing request from the next process. For such a problem, it is conceivable that the system automatically formulates a production plan.

However, even when the system automatically formulates a production plan, it may be necessary to change the processing order of products according to the operating status of the factory or the express shipping request from the customer. Therefore, it is necessary for flexible factory operation to allow the operator to manually change the processing order of products while considering the above-mentioned restrictions.

By the way, when changing the processing order of products, the operator considers the change for each product, but in the case of the above-mentioned batch processing equipment, since one batch is composed of a plurality of products, a plurality of products are used. Need to be changed. If it is forcibly changed for each product, there is a concern that productivity may deteriorate or delivery may be delayed due to a decrease in the processing amount of one batch with respect to the installed capacity. However, it is not possible to flexibly change the batch unit, and it is difficult for the operator to change the processing order of the products while considering the restrictions of the batch processing equipment. Therefore, it is desired to realize a system in which the system picks up the change request manually by the operator and formulates a plan satisfying various restrictions in accordance with the request.

Therefore, in the present embodiment, first, the initial plan information is expanded from the batch unit to the product unit, the operator manually changes the processing order of the products, and the changed processing order is set as the desired processing order. Next, the batch is reformed according to the desired processing order specified by the operator, with the constraint of whether or not the batch can be combined into the same batch. After that, when the reshaped batch has a margin in equipment capacity or the processing is not delayed, the processing is performed to combine the reformed batches into one batch.

Further, in the present embodiment, processing is also performed so that the productivity and the degree of on-time delivery of the initial plan and the revised plan can be compared as evaluation indexes.

Then, the initial plan evaluation index acquired from the information acquisition unit 11 and the revised plan evaluation index calculated here are included in the revised plan screen and displayed on the display mechanism 95 (see FIG. 14). In the present embodiment, the initial plan evaluation index is used as an example of the first evaluation index which is the evaluation index of the first batch plan information, and the second evaluation which is the evaluation index of the second batch plan information. The revised plan evaluation index is used as an example of the index, and the evaluation index calculation unit 15 is provided as an example of the evaluation index output unit that outputs the first evaluation index and the second evaluation index in a comparable format. ing.

[Concrete example]
First, among the various information acquired by the information acquisition unit 11, product information, initial plan information, and initial plan evaluation index will be described.

FIG. 2 is a diagram showing an example of product information. As shown in the figure, the product information includes the product ID, the processing summary condition, and the delivery date.

The product ID is information that identifies the product. In the figure, the product ID is indicated by the characters a to x, but if the product can be identified, information other than the characters may be adopted. In the following, the products having product IDs a to x may be referred to as products a to product x, respectively.

The processing summary condition is a condition for determining whether or not the product identified by the corresponding product ID can be grouped in the same batch as other products. Here, two conditions are assumed as processing summary conditions, and they are represented by α and β. Specific examples of this condition will be described later.

The delivery date is the delivery date of the product identified by the corresponding product ID.

FIG. 3 is a diagram showing an example of initial plan information. As shown in the figure, the initial plan information includes a batch number, a processing summary condition, a processing start time, a processing end time, and product IDs (1) to (4).

The batch number is a number that identifies the batch processing assigned to the batch processing in the processing order. In the following, the batch having the batch number n may be referred to as batch n.

The processing summary condition is a condition for discriminating the products to be summarized in the batch process identified by the corresponding batch number. Here, as described above, two conditions are assumed as processing summary conditions, and they are represented by α and β. Specific examples of this condition will be described later.

The processing start time is the time when the batch processing identified by the corresponding batch number starts, and the processing end time is the time when the batch processing identified by the corresponding batch number ends. Here, for a batch whose corresponding processing summary condition is α, the time required for batch processing is 24 hours, and for a batch whose corresponding processing summary condition is β, the time required for batch processing is 28 hours and 48 minutes. There is.

The product IDs (1) to (4) are product IDs of products that are collectively processed by batch processing identified by the corresponding batch numbers. Here, since the equipment targeted in the present embodiment can process four products at a time, four product IDs are included.

FIG. 4 is a diagram showing an example of the initial plan evaluation index. As shown in the figure, the initial plan evaluation index includes productivity and the delivery date compliance rate, which is an example of the delivery date compliance degree, as the initial plan evaluation value. In the initial plan, 24 products are processed in 6 batches, so the productivity is 4 batches / batch. Further, by comparing the delivery date of each product in the product information with the processing end time of each product in the initial plan information, it can be seen that no delay in delivery has occurred, so that the delivery date compliance rate is 100%. Although the initial plan evaluation index includes both the productivity and the delivery date compliance rate here, it may include at least one of the productivity and the delivery date compliance rate.

Here, a specific example of the processing summary condition will be described.

FIG. 5 is a diagram showing an example of processing summary conditions. Here, as an example of the treatment summary condition, the condition that the temperature pattern (heat treatment pattern) in the batch annealing equipment is the same is taken as an example. In other words, as a batch process, a batch annealing process in which a plurality of products having the same temperature pattern are collectively processed is taken as an example. The temperature pattern can be expressed by three processes of temperature rise, soaking, and temperature lowering. Of these, the process of raising and lowering the temperature can be expressed by the inclination and the processing time, and the process of soaking heat can be expressed by the processing temperature and the soaking time. Although only one temperature pattern is shown in the figure, this corresponds to, for example, the processing summary condition α. Then, although not shown, there is another temperature pattern, which corresponds to the processing summary condition β.

Next, the post-deployment plan information generated by the plan information development unit 12 expanding the initial plan information will be described.

FIG. 6 is a diagram showing an example of post-deployment plan information. As shown in the figure, the post-deployment plan information includes a product ID, a processing summary condition, a delivery date, an arrival time, a processing start time, and a processing end time.

As described above, the product ID is information that identifies the product. In this product ID, the product IDs (1) to the product IDs (4) in the initial plan information are rearranged separately for each line.

As described above, the processing summary condition is a condition for determining whether or not the product identified by the corresponding product ID can be grouped in the same batch as other products. This processing summary condition is a copy of the processing summary condition included in the initial plan information.

The delivery date is the delivery date of the product identified by the corresponding product ID. This delivery date is a copy of the delivery date included in the product information.

The arrival time is the time when the product identified by the corresponding product ID arrives at the batch processing facility. This arrival time is a copy of the arrival time included in the previous process information acquired by the information acquisition unit 11.

The processing start time is the time when the batch processing for processing the product identified by the corresponding product ID starts. This processing start time is a copy of the processing start time included in the initial plan information.

The processing end time is the time when the batch processing for processing the product identified by the corresponding product ID ends. This processing end time is a copy of the processing end time included in the initial plan information.

The plan information development unit 12 displays the post-development plan information on the display mechanism 95 (see FIG. 14) by associating the products with the processing order in order from the top. On the other hand, the operator corrects this processing order by using the input device 96 (see FIG. 14). Then, the desired processing order acquisition unit 13 acquires the desired processing order of the product from this modification result.

Next, the modified order information including the desired processing order acquired by the desired processing order acquisition unit 13 will be described.

FIG. 7 is a diagram showing an example of corrected order information. As shown in the figure, the modified order information includes a product ID, a processing summary condition, a delivery date, and a desired processing order.

As described above, the product ID is information that identifies the product. This product ID may be, for example, a copy of the product ID included in the post-deployment plan information.

As described above, the processing summary condition is a condition for determining whether or not the product identified by the corresponding product ID can be grouped in the same batch as other products. This processing summary condition may be, for example, a copy of the process summary condition included in the post-expansion plan information.

The delivery date is, as described above, the delivery date of the product identified by the corresponding product ID. This delivery date may be, for example, a copy of the delivery date included in the post-deployment plan information.

The desired processing order is the processing order desired by the operator for the product identified by the corresponding product ID. In the post-deployment plan information of FIG. 6, the processing order of the product i was the ninth, but in this modified order information, the desired processing order of the product i is set to the fifth as shown in a thick frame in the figure. There is. For example, since it is necessary to process the product i at an early stage due to a customer's request or the like, it is conceivable to bring the processing order of the product i to the front.

Next, the modified plan information generated by the plan information correction unit 14 based on the expanded plan information and the modified order information will be described.

FIG. 8 is a diagram showing an example of the revised plan information. As shown in the figure, the modified plan information includes a batch number, a processing summary condition, a processing start time, a processing end time, and product IDs (1) to (4).

As described above, the batch number is a number that identifies the batch processing assigned to the batch processing in the processing order. However, since the processing order of the products in the initial plan information is changed in the modified plan information, the set of product IDs (1) to (4) included in the initial plan information is included in the modified plan information as it is. Even so, the initial plan information and the modified plan information do not always have the same batch number for the set.

As described above, the processing summary condition is a condition for determining the products to be summarized in the batch process identified by the corresponding batch number.

As described above, the processing start time is the time when the batch processing identified by the corresponding batch number starts. However, this processing start time is not necessarily a copy of the processing start time included in the initial plan information, but is newly calculated according to the desired processing order for each product included in the modified order information. It may be the time.

As described above, the processing end time is the time when the batch processing identified by the corresponding batch number ends. However, this processing end time is not necessarily a copy of the processing end time included in the initial plan information, but is newly calculated according to the desired processing order for each product included in the modified order information. It may be the time.

As described above, the product IDs (1) to (4) are product IDs of products that are collectively processed by batch processing identified by the corresponding batch numbers. The product IDs (1) to (4) are the product IDs (1) to (4) included in the initial plan information according to the desired processing order for each product included in the modified order information. It has been changed.

Hereinafter, the schematic operation when the plan information correction unit 14 changes the expanded plan information of FIG. 6 according to the desired processing order included in the modified order information of FIG. 7 and generates the modified plan information of FIG. Will be explained.

First, the plan information correction unit 14 forms a batch based on the product a. Specifically, among the products included in the modified order information, the products that can be processed in the same batch as the product a are selected from the ones with the earliest desired processing order, and the products that arrive at the batch processing facility at the processing start time are selected. Products that can be processed in the same batch. In the example of the figure, the processing start time of the batch for processing the product a is 0:00 on March 7, 2019, and the arrival times of the products a, b, c, and d are all higher than this in the post-deployment plan information. Since it is in front, one batch is formed by products a, b, c, and d.

Next, the plan information correction unit 14 forms a batch based on the product i. In the initial plan information of FIG. 3, the products that can be processed in the same batch as the product i are the products i, j, k, l. However, due to the change in the processing order of the product i, the processing start time of the batch processing the product i is 0:00 on March 8, 2019, and the products k and l have not arrived at the batch processing facility at this point. , As shown in the figure surrounded by a thick frame, a batch is formed only by the products i and j.

After that, the plan information correction unit 14 repeats the same process, and ends the process when all the products are planned.

Next, the revised plan evaluation index calculated by the evaluation index calculation unit 15 will be described.

FIG. 9 is a diagram showing an example of the revised plan evaluation index. As shown in the figure, the revised plan evaluation index includes productivity and the delivery date compliance rate, which is an example of the delivery date compliance degree, as the revised plan evaluation value. In the revised plan, 24 products are processed in 7 batches, so the productivity is 3.4 bottles / batch. In addition, by comparing the delivery date of each product in the revised order information with the processing end time of each product in the revised plan information, it can be seen that there is no delay in delivery, so the delivery date compliance rate is 100%. There is. Although the revised plan evaluation index includes both the productivity and the on-time delivery rate here, it may include at least one of the productivity and the on-time delivery rate.

Next, the modified planning screen displayed on the display mechanism 95 (see FIG. 14) by the evaluation index calculation unit 15 will be described.

FIG. 10 is a diagram showing an example of the modified plan screen 50. As shown in the figure, the revised plan information screen 50 includes a revised plan information area 51, an initial plan evaluation index area 52, a revised plan evaluation index area 53, a modified confirmation button 54, and a modified cancel button 55. ..

The revised plan information area 51 includes the revised plan information shown in FIG.

The initial plan evaluation index area 52 includes the initial plan evaluation index shown in FIG. The evaluation index calculation unit 15 acquires the initial plan evaluation index from the information acquisition unit 11 and includes it in the initial plan evaluation index area 52.

The revised plan evaluation index area 53 includes the revised plan evaluation index shown in FIG. The evaluation index calculation unit 15 calculates the revised plan evaluation index based on the revised plan information acquired from the plan information correction unit 14, and includes this in the revised plan evaluation index area 53.

In this example, the productivity in the initial plan evaluation index area 52 is 4 lines / batch, and the productivity in the modified plan evaluation index area 53 is 3.4 lines / batch, so that the productivity of the evaluation indexes deteriorates. The result is that. By including these evaluation indexes in the revised plan screen 50, the operator can objectively determine whether to finalize the plan, re-correct it, or return to the initial plan.

The correction confirmation button 54 is a button for confirming the correction of the initial plan information. When the correction confirmation button 54 is pressed, the initial plan information is overwritten by the revised plan information.

The correction cancel button 55 is a button for canceling the correction of the initial plan information. When the correction cancel button 55 is pressed, the revised plan information is deleted.

[Operation of production plan correction device]
FIG. 11 is a flowchart showing an operation example of the production plan correction device 10 according to the present embodiment.

As shown in the figure, in the production plan correction device 10, first, the information acquisition unit 11 acquires various information used in each processing unit (step 101). Here, as described above, the various information includes the product information of FIG. 2, the initial plan information of FIG. 3, the initial plan evaluation index of FIG. 4, the batch processing time information, and the pre-process information.

Next, the plan information expansion unit 12 performs the plan information expansion process using the product information, the initial plan information, and the previous process information acquired in step 101 (step 102). As a result, the plan information development unit 12 generates the post-expansion plan information shown in FIG. The details of this plan information expansion process will be described later.

Then, the plan information development unit 12 displays the post-deployment plan information generated in step 102 on the display mechanism 95 (see FIG. 14) (step 103). Specifically, the processing order is associated and displayed for each product included in the post-deployment plan information.

Next, the operator corrects the processing order associated with the product in the post-deployment plan information displayed on the display mechanism 95 (see FIG. 14) in step 103 by using the input device 96 (see FIG. 14). To do. Then, the desired processing order acquisition unit 13 acquires the modified processing order as the desired processing order (step 104). As a result, the desired processing order acquisition unit 13 generates the modified order information shown in FIG. 7.

Next, the plan information correction unit 14 performs the plan information correction process using the post-deployment plan information generated in step 102 and the post-correction order information generated in step 104 (step 105). As a result, the plan information correction unit 14 generates the revised plan information shown in FIG. The details of this plan information correction process will be described later.

After that, the evaluation index calculation unit 15 calculates the revised plan evaluation index of FIG. 9 based on the revised plan information generated in step 105 (step 106).

Then, the evaluation index calculation unit 15 displays a revised plan screen (see FIG. 10) including the initial plan evaluation index acquired in step 101 and the revised plan evaluation index calculated in step 106 in a comparable format. , Displayed on the display mechanism 95 (see FIG. 14) (step 107).

Next, the plan information expansion process in step 102 will be described in detail.

FIG. 12 is a flowchart showing the flow of the plan information expansion process.

As shown in the figure, the plan information development unit 12 first reads a row of one batch from the initial plan information acquired in step 101 of FIG. 11 (step 201).

Next, the plan information development unit 12 acquires the processing summary condition, the processing start time, and the processing end time from the batch rows read in step 201 (step 202).

Next, the planning information development unit 12 pays attention to one product included in the row of the batch read in step 201 (step 203). Specifically, one product ID is acquired.

Then, the plan information development unit 12 acquires the delivery date of the product identified by the product ID acquired in step 203 from the product information acquired in step 101 of FIG. 11 (step 204).

Further, the planning information development unit 12 acquires the arrival time of the product identified by the product ID acquired in step 203 from the previous process information acquired in step 101 of FIG. 11 (step 205).

As a result, the plan information development unit 12 has the product ID acquired in step 203, the processing summary condition acquired in step 202, the delivery date acquired in step 204, the arrival time acquired in step 205, and the processing start time acquired in step 202. And the processing end time is written out in the post-expansion plan information (step 206).

After that, the planning information development unit 12 determines whether or not there is another product in the row of the batch read in step 201 (step 207). Specifically, it is determined whether or not another product ID is included.

As a result, if it is determined that there is another product in the row of the batch read in step 201, the planning information expansion unit 12 returns the process to step 203 and executes the processes of steps 203 to 206 for the other products. ..

On the other hand, if it is not determined that there is another product in the batch row read in step 201, the plan information expansion unit 12 determines whether or not there is another batch row in the initial plan information (step 208). Then, if it is determined that the initial plan information has a row of another batch, the plan information expansion unit 12 returns the process to step 201, and executes the processes of steps 201 to 207 for the row of the other batch. Further, if it is not determined that the initial plan information has a row of another batch, the plan information expansion unit 12 ends the process.

Next, the plan information correction process in step 105 will be described in detail.

FIG. 13 is a flowchart showing the flow of the plan information correction process.

As shown in the figure, the plan information correction unit 14 first reads a row of unselected products including the earliest desired processing order from the corrected order information generated in step 104 of FIG. 11 (step 401).

As a result, the plan information correction unit 14 determines whether or not the row reading of such a product is successful (step 402). That is, it is determined whether or not there is a line of such a product in the modified order information.

As a result, if it is not determined that the row reading of such a product is successful, there is no product that serves as a reference for batch processing, and the plan information correction unit 14 ends the processing.

On the other hand, if it is determined that the row of such a product has been successfully read, the plan information correction unit 14 determines the processing start time and the processing end of the batch processing based on the product included in the product row read in step 401. Determine the time (step 403). Specifically, when the batch process targeted this time is the first batch process, the product included in the product line read in step 401 from the post-deployment plan information generated in step 102 of FIG. The processing start time and processing end time corresponding to the ID may be acquired, and these may be used as the processing start time and processing end time of batch processing. When the batch process targeted this time is the second and subsequent batch processes, the process end time of the previous batch process is set as the process start time of the batch process targeted this time. Then, from the batch processing time information acquired in step 101 of FIG. 11, the batch processing time corresponding to the processing summary condition included in the row of the product read in step 401 is acquired, and the processing start time of the batch processing targeted this time is acquired. The time obtained by adding this batch processing time to the current batch processing may be set as the processing end time of the target batch processing this time.

Next, the plan information correction unit 14 determines whether or not the arrival time of the product included in the line of the product read in step 401 is earlier than the processing start time of the batch processing calculated in step 403 (step). 404). Here, the arrival time of the product may be acquired from the pre-process information acquired in step 101 of FIG.

As a result, if it is not determined that the arrival time of the product is earlier than the processing start time of the batch processing, the product has not arrived and the batch processing cannot be started. Therefore, the plan information correction unit 14 processes. Return to step 401 to find another product that serves as a basis for batch processing.

On the other hand, if it is determined that the arrival time of the product is earlier than the processing start time of the batch processing, the product has arrived and the batch processing can be started. Therefore, the plan information correction unit 14 determines the product. It is selected as a reference product for batch processing (step 405). Specifically, the product ID of the product is retained as the product ID of the product that is the reference for batch processing.

Next, the plan information correction unit 14 selects a line of unselected products including the earliest desired processing order having the same processing summary conditions as the product selected in step 405 from the corrected order information generated in step 104 of FIG. Is read (step 406).

As a result, the plan information correction unit 14 determines whether or not the row reading of such a product is successful (step 407). That is, it is determined whether or not there is a line of such a product in the modified order information.

As a result, if it is not determined that the row reading of such a product is successful, there is no product that can be processed by the same batch process, so the plan information correction unit 14 proceeds to the process to step 411.

On the other hand, if it is determined that the row of such a product has been successfully read, the plan information correction unit 14 determines that the arrival time of the product included in the row of the product read in step 406 is the batch processing calculated in step 403. It is determined whether or not it is before the processing start time (step 408). Here, the arrival time of the product may be acquired from the pre-process information acquired in step 101 of FIG.

As a result, if it is not determined that the arrival time of the product is earlier than the processing start time of the batch processing, the product has not arrived and the batch processing cannot be started. Therefore, the plan information correction unit 14 processes. Go back to step 406 to find another product that can be processed in the same batch process.

On the other hand, if it is determined that the arrival time of the product is earlier than the processing start time of the batch processing, the product has arrived and the batch processing can be started. Therefore, the plan information correction unit 14 determines the product. Select as a product that can be processed in the same batch process (step 409). Specifically, the product ID of the product is held as the product ID of the product that can be processed by the same batch processing.

Further, the plan information correction unit 14 determines whether or not the total number of products selected in steps 405 and 409 has reached the installed capacity (step 410).

As a result, if it is not determined that the total number of products has reached the installed capacity, the plan information correction unit 14 returns the process to step 406 and searches for another product that can be processed in the same batch process.

On the other hand, if it is determined that the total number of products has reached the installed capacity, the plan information correction unit 14 converts the batch number, the processing summary condition, the processing start time, the processing end time, and the product ID into the corrected plan information. Export (step 411). Specifically, when the batch process targeted this time is the first batch process, "1" is set as the batch number to be written out, and when the batch process targeted this time is the second and subsequent batch processes. May be the batch number to be written out by adding "1" to the batch number of the previous batch process. Further, the processing summarizing condition included in the line of the product selected in step 405 may be set as the processing summarizing condition to be written out. Further, the processing start time and processing end time of the batch processing determined in step 403 may be set as the processing start time and processing end time to be written out. Furthermore, the product ID of the product selected in steps 405 and 409 may be the product ID to be written out.

When the product ID is written out in step 411, it is memorized that the line is selected for the line including the product ID in the modified order information of FIG. 7, and in steps 401 and 406, the line is selected. It should be used to determine if a row of products is unselected.

After that, the plan information correction unit 14 returns the process to step 401, and repeats the processes of steps 401 to 411 until it is no longer determined that the reading was successful in step 402.
