FIG. 11 is a block diagram showing an example of a conventional production process flow creating system, and FIG. 12 is a diagram for explaining the operation of the conventional example shown in FIG.

In FIGS. 11 and 12, this conventional example outlines the disclosure of Japanese Patent Application Laid-Open No. 5-26629.

[0009]

The conventional manufacturing process flow creation check system and creation / check method have the following problems.

The first problem is that, when the conventional manufacturing process flow check system has hundreds of manufacturing processes, the process flow data in one manufacturing process or the process flow including the preceding and following processes is included. Even if the data is created while checking whether the data is correct, errors in the process flow cannot be prevented. As a result, if it is determined that the entire process flow data is not correct as a whole after creating the process flow data, it will be necessary to repeat the process unit correction again, and it will take a long time to obtain the correct process flow. That is to say.

The reason is that when the manufacturing process flow data is created, only the correctness of the data of each process and the preceding and succeeding processes is determined, and the correctness of all the processes is not determined.

After a process flow is created by a process flow creation system described in Japanese Patent Application Laid-Open No. 5-26629,
There is also a method of checking with a process flow check system described in JP-A-6-176994. However, if a change occurs in the original process flow after the check is performed, the change and the check are repeated, which takes time. Become.

[0013] The second problem is that the conventional manufacturing process flow creation system requires a huge amount of time, especially for creating a process flow for several hundred processes.

The reason is that in a conventional process flow creation system, manufacturing process flow data must be created in units of one manufacturing process. Even when an existing process flow is copied and created, if there are a plurality of correction points, it must be corrected and created in units of one manufacturing process.

A third problem is that when an existing process flow is copied and process codes and conditions are added or deleted over a plurality of processes, an error may occur in the corrected process flow.

The reason is that when a plurality of steps are added to or deleted from the process flow for several hundred steps, the correlation with other preceding and succeeding steps cannot be immediately checked.

A fourth problem is that, for example, when equipment in a line is changed, there is a possibility that an appropriate process flow correction is not applied to all types.

The reason is that, when a process flow of a similar type is created, a plurality of types are created by copying the process flow of the already created stack, so that the process flow of the plurality of types differs in small points. , If there are multiple similar process flows, and the process flow of the copy source is a process flow that does not match the actual line status, the process flow creator can forget to correct it if it is not aware of it This is because the nature is high.

(Purpose) An object of the present invention is to provide a method and system for creating and checking a manufacturing process flow in which anyone can easily and accurately create a plurality of long manufacturing process flows according to the actual conditions of a manufacturing line in a short time. Is to do. It is another object of the present invention to provide a method and system for creating and checking a manufacturing process flow according to the actual conditions of a manufacturing line.

FIG. 9 is a view showing an example of a transport process table according to the second embodiment.

Next, the operation of one example of the second embodiment of the present invention will be described in detail with reference to FIGS.

In the present system, when the manufacturing process flow data to be checked is provided from the manufacturing process information creating unit 10 in FIG. 8, it is continuously processed in the inference unit 9a in FIG. 8 by block rule data as shown in FIG. It is determined as a block rule data group composed of manufacturing processes. Thereafter, the compatibility between blocks is determined based on the inter-block rule data as shown in FIGS.

In the process flow block rule data input section 3 shown in FIG. 8, first, when expressing block rule data as shown in FIG. 5, a derived block flag is provided to represent a very similar block as a derived block. The derivation of the derived block is achieved by providing the start step, the middle step, and the end step discrimination flag of the block. For example, as a block code of “A01”,
When “A01 → J41” and “A01 → J41 → K04 (or K06 or ZL0)” can be determined as having the same meaning, as shown in FIG. 6, the third sequence (order) derivation flag is written as “1”. Derived blocks are represented by this. As the start / end flag, “E” is written in all data that can be regarded as end.

Further, when there are a plurality of derived blocks, these are represented by having a plurality of derived block flags. If there is a derived block, as shown in FIG. 5, "0" is entered for the process required for the derived block corresponding to the record of the derived flag 2, and "1" is entered for the process that may not be present. Express by doing.

Further, for example, a transportation step having a low importance as block determination knowledge is represented by a transportation step flag file or the like in the process flow data input section 3 and the inference section 9.
By skipping these steps when inferring in a,
It is not necessary to describe a continuous process including a transport process and the like. As the skipping step, for example, as shown in FIG. 9, by specifying a step code corresponding to the transport step, the corresponding step is skipped at the time of inference. The transfer process data is converted by the process flow block rule data converter 6 and stored in the transfer process data storage 6.

Next, in the process flow data input section 3, a plurality of steps which may exist in the same order in the block are described using a delimiter such as a comma. FIG.
If there is a possibility that a plurality of processes can be performed in the same order as in the process code “K04, K06, ZL0” of the order “3” of the block code “A01” of the block code “A01”, a plurality of notations using a delimiter such as a comma I do. The process flow block rule data conversion unit 6 converts the data with the above-mentioned related information and stores the data in the process flow data storage unit 5. In the process flow block rule data input unit 3, when a plurality of process codes can be described as the same knowledge with respect to the process code, the plurality of codes are combined into one using a so-called wild card symbol such as "*". , The number of steps existing in the same order is reduced. The symbol used for the wildcard notation may be a symbol other than “*”, such as “+”. “R8” in FIG.
By using a symbol such as a wild card such as “*”, it is expressed that any character in the first place corresponds to the block rule. At this time, the wildcard data is
It is automatically extracted by the process flow data converter 4 and stored in the wildcard data storage 7.

Finally, mixed control such as "R **" and "R0 *" is made possible by performing exclusive control using symbols such as wild cards. In FIG. 5, when there is only data of “R81” in other data (here, the second order of the block code “A02”), the first order of the block code “R80” includes “R81”. R8
* "To represent data that satisfies" R8 *, R
81 ". Conversely, when it is not desired to include “R81”, only “R8 *” is set as in the second order. At this time,
The wild card data is automatically extracted by the process flow data conversion unit 4 and stored in the wild card data storage unit 7 as described above.

In the block determination, the manufacturing process flow data is changed to the block code “A01 → A02 → A03 → A0”.
4 ". At this time, as shown in FIG.
In the flow of “A01 → A02”, “△” is described in the inter-block rule, so that there is a “possible problem” in the inter-block determination, and “A02 → A0” is determined.
In the flow of “3”, since “」 ”is described in the inter-block rule, the determination between blocks is“ No problem ”, and in the flow of“ A03 → A04 ”, the cross rule is“ X ”. Since it is described, it is determined that there is a problem in the inter-block determination.

The current block and the next block are shown in FIG.
Assume that there is a rule relationship as shown in FIG. In FIG. 7, “●” means no problem, and “×” is prohibited. This rule expression is shown in FIG. 7B or FIG.
It is equivalent even if it expresses like. That is, “A → B”
Considering the flow of the block, in FIG. 7A, when the current block name “A” and the next block name “B” are viewed in a table,
In FIG. 7B and FIG. 7C, the corresponding rule shows “OK” in the answer column.

[0073]

As described above, according to the present invention, when a process flow is prepared, when a plurality of processes are prepared in advance as a plurality of blocks in a packaged form, the blocks are correctly prepared according to a preset block rule. Determining means for determining whether or not the process has been performed; a process flow creating check means for simultaneously creating a process flow by bonding a plurality of blocks and simultaneously determining whether the entire process flow is correct or not; and a process created using another means or the like. A check means for checking whether a flow has been registered in advance but created using a standard block is provided, and when checking the created process flow, a plurality of processes are packaged in advance as a block. Based on the prepared knowledge, determine which process flow is composed of blocks. By the accuracy determination process flow created based on previously prepared interblock rule checking method capable of obtaining the following effects.

The first effect is that, while creating the manufacturing process flow, it is checked whether the arrangement is in conformity with the actual condition of the line. As a result, it is possible to reduce the time required to repeatedly execute a cycle of creating and checking all the process flows, correcting all the defective rows again, and further checking.

The reason is that the process flow is set up while selecting from among the block rule data registered in advance, blocks that can be matched.

A second effect is that it is possible to determine whether or not the manufacturing process flow is composed of standard blocks by the manufacturing process flow check. As a result,
The process flow can be checked accurately and at high speed, and check errors can be reduced.

The reason is that blocks are formed by a combination of a process code and a condition code to clarify a rule for combining blocks, and that a check is performed in block units.

The third effect is that the knowledge base for checking can be reduced. As a result, the process flow can be checked at a high speed, and maintenance can be easily performed.

The reason is not only to check the context of each process name, but not to determine whether the process flow is appropriate, but to check the arrangement in blocks and the rule check between blocks. That's because they are going too.
