Next, a procedure for creating another data file by processing and editing a previously stored data file, and means for realizing various other functions will be described in detail.

First, when the user defines the projection of each function on the device using the input device 3, the definition of the data files corresponding to the second data table 15 and the third data table 17 is performed. A procedure of creating a data file corresponding to the first data table 13 based on the information will be described with reference to the flowchart of FIG.

When the user defines the projection of each function on the device, the first data table 13 or block diagram 14
Is displayed (step 221), and it is designated to define the projection of each function on the device (222). At this time, a field for inputting the device name and the function projected to the device is displayed outside the field of the first data table 13 or the first block diagram 14 (223). Using this, the user first enters the device name (224) and then the function projected to that device is illustrated directly in the box or in the first block diagram 14. It is input by picking a function (225). When the input of the projected function is completed (226), the next device name is input and the same input is performed. When all input is completed (227), definition information is stored in the data file corresponding to the first data table 13 (228).

Based on this definition information, the second data table 1
The procedure for creating the data files corresponding to the fifth and third data tables 17 will be described below.

First, the third data table 17 will be described.

Information regarding each function and each database in the first data table 13 is classified for each device based on the definition information of the projection (229). When the classification is completed, a data file corresponding to the third data table 17 is generated for each device (230). At this time, in the information about each function, the name 35 of the function to be processed immediately before, the name 36 of the information passed from the function to be processed immediately before, and the amount of information 3
7. Required database name 38, Information volume 39
With respect to, regarding the definition information of the projection, it is scanned whether or not the function to be processed immediately before and the required database are in the same device (231).

Of the information relating to each database, the name 44 of the function to be accessed, the name 45 of the information passed from the function to be accessed, and the amount 46 of information are also scanned. If it is in the same device (232), as it is, the name 85 of the function in the same device that is processed immediately before, the name 86 of the information passed from the function in the same device that is processed immediately before, the amount 87 of information, necessary The name 88 of the database in the same device, the amount of information 89, or the name 112 of the function in the same device that accesses the database, the name 113 of the information passed from the function in the same device to access,
The amount of information 114 is stored in the data file corresponding to the third data table 17 (233).

If not in the same device (232), the name 35 of the function to be processed immediately before and the name 44 of the function to be accessed are "reception function n" (n is a unique numerical value assigned to each reception function). And then stored in the data file corresponding to the third data table 17 (2
34). The information regarding the “reception function n” is generated on the data file corresponding to the third data table 17 at this time. First, the function outside the device and the device name to which the database belongs are written as the name 94 of the device to be transmitted. The function-specific number 90 is assigned by the processing device 1,
“Reception function n” is written in the name 91, and the processing load 9
2 is waiting for user input. The frequency of occurrence 93, the name 95 of information to be transmitted, and the amount 96 of information are copied from the above-mentioned information regarding the function (235). The same procedure is repeated until the scanning of information regarding each function and each database classified for each device is completed (236).

When information regarding each function other than the transmitting function and each database is generated for each device, finally, information regarding the transmitting function is generated as follows. That is, first, for a certain device, the functions outside the device and the database are searched for the function inside the device, the function requiring the database, and the database accessed by the function inside the device (237). If found (238), information about "sending function n" (n is a unique numerical value assigned to each sending function) is generated on the data file corresponding to the third data table 17 (239). The function-specific number 97 is assigned by the processing device 1, “transmission function n” is written in the name 98, and the processing load 99 is on standby for user input. In the name 106 of the partner device to be transmitted, the retrieved function outside the device and the name of the device to which the database belongs are written, the occurrence frequency 100, the name 101 of the function in the same device that is processed immediately before this function, Name 102 of information passed from the function in the same device that is processed immediately before, amount 103 of information, name 104 of database in the same device required by this function, amount 105 of information, name 107 of information transmitted , The amount of information 108 is copied from the information about the retrieved, function, database described above. When the search of the function outside the device and the database is completed (240), the generation of the information regarding the transmission function of the device is completed. When the generation of the information regarding the transmission function of all the devices is completed (241), the generation of the data file corresponding to the third data table 17 is completed.

Next, a procedure for creating a data file corresponding to the second data table 15 will be described below.

First, the device-specific number 61 and name 62 are written in the data file for each device (242).
Next, using the data file for each device corresponding to the third data table 17, the total processing load (per second) and the capacity of the database for each device are calculated, and the processing load 63, the database on the data file is calculated. It is written in the item of the capacity 64 of (243). Finally, in the information about the receiving function of the data file corresponding to the third table 17,
Device name 94 to send, information name 95 to send,
The amount of information 96, the frequency of occurrence 93, and the name 106 of the partner device to be transmitted, the name of the information to be transmitted 107, the amount of information 108, the frequency of occurrence 1 among the information related to the transmission function
00 is the name of the device to be transmitted to this device, the name 66 of the information to be transmitted, the amount of information 67, the reception frequency 68, and the other party to which this device transmits, in the data file corresponding to the second data table 15. The name 69 of the device, the name 70 of information to be transmitted, the amount 71 of information, and the transmission frequency 72 are written for each device (244).

As described above, the data files corresponding to the second data table 15 and the third data table 17 are defined when the user defines the projection of each function on the device using the input device 3. It is created from a data file corresponding to the first data table 13 based on the information.

Secondly, a procedure for creating the data file corresponding to the first block diagram 14 from the data file corresponding to the first data table 13 will be described with reference to FIG. First, according to the data file corresponding to the first data table 13, f (i, j) (i = 1 to
0 or 1 is substituted for n, j = 1 to n). However, n is the function of the first data table 13 and the number of databases, and f (i, j) is the function with the number i, the information flow from the database to the function with the number j to the database. It is assumed to be 1 when it does, and 0 when it does not exist. Solve the following integer programming problem using f (i, j).
