2. Description of the Related Art In recent years, various user demands for software cause an increase in the amount of software development, and as a result, the importance of process control in software development is increasing. A feature of software components is that there are a plurality of products produced by the same work process.

For example, the components of the system can be roughly divided into three groups of "user interface", "data input / output", and "internal processing", and each group is "design", "manufacture", " It is created through a work process such as “test”. In addition, the software production plan is frequently partially modified and changed as it progresses.

It is necessary to grasp all work processes for managing the software development process as described above, but one work process is added each time the production plan is changed.

A control modem and an application exist in the lower layer of the system, and a common sub and subsystem exist in the lower layer of the application. The subsystems a and b are components produced in the same work process, and the subsystem is set as integrated data that integrates these components.
Further, a subroutine exists in the lower layer of the common sub, and a task exists in the lower layer of the subsystem.

Reference numeral 2 is work data representing work, and its elements include functional design, mechanism design, design, production, test, and integration test. Of these, design, production, and test are integrated into a group called design production. There is. Three, four, five, six,
Numerals 7 and 8 are arcs connecting the elements of the element data 21 and the work data 2 to both ends of the broken line. It should be noted that the present embodiment obtains the same result as the conventional production plan creating method described with reference to FIG.

The production plan creation method of the present invention uses element data 21
And the work data 2 are prepared so that the creator makes the elements correspond one-to-one with the arcs 3, 4, 5, 6, 7,
8 is set, and the work sequence is set to this arc to create a system production plan. At this time, the subsystem in which the subsystems a and b are integrated is treated as a component of the system, and the arc 5 that associates “subsystem” with “design” and the arc 6 that associates “subsystem” with “production”. , An arc 7 that associates the "subsystem" with the "test".

In the production planning method described with reference to FIG. 1, when the arc work order is set to 3, 4, 5, 6, 7, 8 to create the production plan, the result is as shown in FIG. Create the same production plan.

The procedure for carrying out the above-mentioned production planning method using a computer and this software will be described in detail. First, the element data, the work data, the integrated data, the arc, and the work sequence to be set for this arc are input to the computer in advance prior to the start of the processing.

FIG. 2 is a flow chart showing the processing procedure of the production plan creating method prepared by software when the above-mentioned data is set as shown in FIG. In the figure, first the arc 3 which is the first arc is selected (S1), then it is judged whether or not the production purpose indicated by this arc 3 is integrated data (S2). Register in the production plan (S8). And all the arcs that have been set
It is determined whether (here, arcs 3, 4, 5, 6, 7, 8) have been registered in the production plan (S6). Since there are arcs that have not been registered yet, the arc 4 corresponding to the next order is selected. (S
9) Then, it returns to S2 again and continues the processing.

In the processing from S2 onward, the arc 4 whose production purpose is not integrated data is registered in the production plan in the same processing procedure as the arc 3, like the arc 3, then the arc 5 is selected and the process returns to S2 again. Continue processing. In S2, it is determined that the product that is the production purpose of the arc 5 is the integrated data, and the subsystem a that is its element (here, subsystems a and b) is selected from the integrated data subsystem (S
3) Generate a new arc that connects the selected subsystem a and the design indicated by the arc 5, and register this in the production plan (S4).

Then, it is determined whether or not all arcs whose production purpose is the element of the integrated data are registered in the production plan (S5). Since the arcs related to the subsystem b have not been registered yet, the subsystem b is selected (S7). ), And returns to S4 to generate a new arc that connects the subsystem b and the design, and registers this in the production plan.

When it is confirmed by the above-mentioned processing that all arcs whose production purpose is the elements of the integrated data subsystem have been registered in the production plan (S5), there are arcs that have not been registered yet (S6), The arc 6 corresponding to the next order is selected, the process returns to S2 and the process is continued. In the processing of S2 and below, arcs 6 and 7 whose production purpose is integrated data like arc 5 are generated in the same processing procedure as arc 5 and registered in the production plan in sequence, then arc 8 is arced. The procedure is the same as that in No. 3, and the process is registered after registering in the production plan.

The production plan created by the above-described processing procedure will be described with reference to FIG. In the figure, arc 5a and arc 5b are generated from arc 5 and the integrated data subsystem in S3, S4, S5 and S7 of FIG. Similarly, arcs 6a, 6b, 7a, 7b were generated from arcs 6, 7 and the integrated data subsystem. The other parts that are the same as those in FIG.

Next, a method for adding a work process in the above-described production plan creating method according to the present invention will be described. FIG.
FIG. 3 is an explanatory diagram showing an example of adding a work process in the production plan creation method according to the present invention described based on FIG. 1. In the figure, reference numeral 31 denotes system element data, which is a configuration in which the subsystem c is added to the subsystem element which is integrated data for integrating the subsystems a and b produced in the same work process. The other parts that are the same as those in FIG. 1 are designated by the same reference numerals, and description thereof will be omitted.

The design of the subsystem c in the production plan of FIG.
When manufacturing and adding tests, the creator in FIG. 3 simply adds “subsystem c” to the elements of the subsystem to create the same production plan as in FIG. 7 by the processing procedure described with reference to FIG.

The above-mentioned production plan will be described with reference to FIG. In the figure, arc 5a, arc 5b and arc 5c are generated from arc 5 and the integrated data subsystem at S3, S4, S5 and S7 in FIG. As well as arc
6a, 6b, 6c, 7a, 7b, 7c were generated from arcs 6, 7 and the integrated data subsystem. The same parts as those in FIG. 3 are designated by the same reference numerals and the description thereof will be omitted. In addition, when deleting a work process, the component produced by a deletion symmetrical work process is deleted from integrated data.
