FIG. 6 shows the procedure of the production management system generation processing in this apparatus. First, in this apparatus, the required specifications of the applicable system are analyzed (step 100), and
As shown in, the specification description unit 1 describes the required specifications for each facility to be managed in the applicable system according to a specification description language such as SFC (step 200).

Here, FIG. 7 shows an example in which the required specifications of the applicable system are described in the SFC language. In this example, the required specifications of the equipment of equipment type 1 shown in FIG. 4 or FIG.
The one described in the FC language is shown. The input command of the equipment type 1 is acceptance of work records between processes. In the figure, the step number (for example, “711” in S711) and the number of the activity to be executed when this step is performed (in the case of S711, “1”).
3 ") indicates the rule of this equipment type which will be described later.

Next, the difference information section 5 calculates the difference between the required specifications of the applicable system described in the SFC language and the standard specifications stored in the standard specification storage section 2 (step 300). The process of obtaining this difference is performed for the number of facilities to be managed.

Here, FIG. 8 shows an example in which the standard specifications are described in the SFC language. In this example, the standard specifications of the equipment of equipment type 1 shown in FIG. 7 are described in the SFC language, and an inter-process work record is accepted as an input command. As in FIG. 7, the step number and the number of the activity executed when shifting to this step in the figure indicate the rule of this equipment type described later.

The difference information between the required specifications and the standard specifications is extracted as follows. ． An activity is not defined in the standard specification, and a step that requires a new activity to realize the requirement specification and the new activity are extracted. ． Activities are defined in the standard specifications, and steps that do not require new activities and the activities are extracted in order to realize the required specifications. ． Activities are defined in the standard specifications,
The steps that need to be changed in order to realize the requirements and the activities are extracted.

Therefore, when the difference between the required specifications of the equipment type 1 shown in FIG. 7 and the standard specifications of the equipment type shown in FIG. 8 is taken, the difference information becomes as shown in the following (1) to (3). . (1). NOP (no function or no processing) in step S71 is changed to activity 11. This step S71
Is a step that is extracted in the above process and has no activity defined in the standard specification, and an activity is required to realize the required specification. (2). Activity 1 in step S721 is NOP
change to. This step S721 is a step which is extracted by the above-mentioned processing and does not need an activity to realize the required specification even if the activity is defined in the standard specification. (3). Activity 13 in step S732 is changed to activity 14. This step S732 is a step that is extracted by the above-mentioned processing and the activity is defined in the standard specification, but the activity needs to be changed in order to realize the required specification.

Then, the rule creating section 7 changes the standard application rule stored in the standard application rule storage section 3 based on the difference information created in this way, to meet the required specifications of the applicable system. Create rules (step 4)
00). That is, as shown in FIG. 1, by copying the standard application rule file stored in the standard application rule storage unit 3 and changing the copied rule file according to the difference information, the rule corresponding to the applicable system is applied. Create a file. Then, the rule changing process according to such difference information is executed for the number of facilities to be managed.

Here, as an example of the rule changing process according to such difference information, the rule changing process of the equipment type 1 will be described.

FIG. 9 shows a standard application rule file for equipment type 1. To show how to read this rule file,
For example, in the case of the rule “111 = 1”, the first “1” indicates the type of “input command” shown in FIG. 3A, and the next “1” indicates “equipment” shown in FIG. 3B. 3), the third "1" indicates the "equipment pattern" shown in FIG. 3C, and "1" after the equal (=) indicates the activity number to be activated (see FIG. 2). Is shown. The same applies to rules such as “711 = 13”.

FIG. 10 shows an example in which the standard application rule file for equipment type 1 shown in FIG. 9 is changed in accordance with the difference information from the difference information creating section 6. Comparing FIG. 9 and FIG. 10, it can be seen from the difference information of (1) that step S7 is performed.
Since the NOP of 1 is changed to the activity 11, the activity 11 is added to the activity 13 started in steps S711 and S712, and “711 = 11, 13” and “712 = 11,
The rule is changed to 13 ".

On the other hand, since the activity 1 in step S721 is changed to NOP due to the difference information in (2) above, when comparing FIG. 9 and FIG. 10, “721 = 1”.
The rule is changed from "721 = NOP".

Further, according to the difference information of (3) above, the activity 13 of step S732 becomes activity 1
Since the number is changed to 4, the rule is changed from “732 = 13” to “732 = 14” by comparing FIG. 9 and FIG. 10.

After the rule creating unit 7 has executed the rule creating process according to the difference information as described above for the number of facilities to be managed, the system creating unit 8 executes only the activities required based on the difference information. The production management system of the standard application system is read out from the standard production management system storage unit 8 while being selected and read out from the storage unit 4. Then, by linking only the necessary activities to the production management system of the standard application system according to the rule created by the rule creation unit 7, a production management system customized according to the required specifications of the applicable system is created. (Step 50
0).

Therefore, according to the present embodiment, the rules of the applicable system are created by comparing the standard specifications of the standard applying system and the standard applying rules, and only the activities required for the required specifications of the applying system are selected. Since the rules and activities are applied to the production management system of the standard application system and the customized production management system is generated in the applicable system, it is possible to easily create customized information such as rules.
