Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work scheduling method in an expert system for scheduling a target work.

[0002]

2. Description of the Related Art In the work scheduling method in the conventional expert system, the pairing of the actual work and the resources required to perform the real work is performed under each constraint condition,
It was generally done by using scheduling and know-how.

[0003]

By the way, in the case of the conventional method, the work to be scheduled is an actual work,
In the actual manual work scheduling, work scheduling is performed based on a certain work concept such as a series of work as a superordinate concept of the actual work.

However, according to the conventional method, the resulting schedule tends to be a schedule result only from the viewpoint of actual work. Therefore, the modification of the schedule based on the above-mentioned work concept is usually performed manually, and the quality is not so good from the viewpoint of the work schedule actually desired by the operator. There wasn't.

The present invention has been made in view of the above conventional circumstances, and an object thereof is to provide a work scheduling method of an expert system which enables high quality scheduling closer to the image of the operator. is there.

[0006]

In order to achieve the above object, the present invention uses a work scheduling method of an expert system to group a plurality of actual works of a target work to create a work group, and to create a predetermined work group. The execution order between work groups that are grouped based on constraint information and know-how information is determined, work groups are sequentially selected from the first work group according to this execution order, and the actual work that belongs to each selected work group The execution order of the above is determined based on the constraint information and know-how information, the first actual work is sequentially selected, and the resource corresponding to each selected actual work is selected based on the constraint information and the know-how information to schedule. Characterized by scheduling the target work by assigning to A.

[0007]

In the present invention, as a superordinate concept of the actual work, the actual work is grouped into several groups to generate a work group, and the execution order between the work groups is determined based on predetermined constraint information and know-how information. Select sequentially from the first working group. Further, the execution order of the actual work belonging to each work group is determined based on the constraint information and the know-how information, and the first actual work is sequentially selected. In this way, the work is scheduled by selecting the work group, selecting the real work belonging to the work group, and selecting the resource corresponding to each real work selected based on the constraint information and know-how information and assigning the schedule. . Therefore, by performing the scheduling based on the work group, which is a superordinate concept of the actual work, and the actual work belonging to the work group, it is possible to perform high-quality scheduling closer to the image of the operator.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a work scheduling method of an expert system according to the present invention. The work scheduling method shown in FIG. 1 operates on the general mechanisms of the expert system used for normal scheduling.

In FIG. 1, reference numeral 100 denotes a knowledge base, which holds work group information 101 and real work information 102. The actual work information 102 refers to the actual detailed work of the work target. For example, in a simple example, work scheduling of installing a plurality of telephones in each room in a building, The actual work involves selecting, purchasing a phone, packing the phone, and carrying it. Therefore, as the actual work information 102, such actual works are determined as the actual work 1, the actual work 2, ...

The work group information 101 is a group of a number of actual works, and is defined as one work group from selection of the model of the telephone to transportation. Therefore, as the work group information 101, it is determined that the entire actual work is grouped into several groups, and each work group is defined as a work group 1, a work group 2, ... Knowledge base 10
The resource information 103 of 0 indicates what is necessary to execute the target work. For example, in the case of the above-mentioned installation of the telephone, this corresponds to a person, a telephone, money for purchasing the telephone, and the like. Therefore, as the resource information 103, such information is determined as the resource 1, the resource 2 ...

The constraint information 104 is a constraint condition for executing the work. For example, from the condition that the old type telephone is not used, the manufacturing year of the telephone, the function of the telephone,
Alternatively, conditions such as not working on Sundays and holidays correspond to this. Therefore, such a constraint condition is the constraint information 10
4 are defined as constraint 1, constraint 2 ... Further, the know-how information 105 refers to know-how in executing the work, and for example, knowledge information such as which company's product is the best for purchasing the telephone at a low price corresponds to this. In the know-how information 105, such knowledge information is determined as know-how 1, know-how 2 ... The schedule work area 106 is an area on the memory of the system, and the actual work scheduling is performed by the schedule work area 1
Performed on 06.

Next, the specific operation of the above embodiment will be described with reference to FIG. In FIG. 2, first, from the work group information 101, the constraint information 104 and the know-how information 10
The execution order / priority order among the work groups is determined based on 5, and the first target work group x is selected (S1). For example, taking the above-mentioned installation work of the telephone as an example, naturally, when starting the work, the first work, that is, the selection of the model of the telephone, the purchase and the like are selected as a work group. Next, actual work information 10
An actual work group belonging to the previously selected work group x is extracted from 2, and the execution order / priority order of the actual work is determined based on the constraint information 104 and the know-how information 105, and the target work group is selected. The actual work y is selected (S2). Here, the actual work to be performed first is selected in the first work group, and for example, the work of selecting the model of the telephone is selected as the first actual work.

When the actual work is selected, the resource information 10
A resource group corresponding to the actual work y selected from among 3 is selected based on the constraint information 104 and the know-how information 105 (S3). For example, if the actual work y is the work of selecting the model of the telephone, the resources corresponding to it include people and materials (catalog etc.) necessary for selecting the model. These processes are performed by the schedule work area 106.
Done on. Next, an assign resource candidate is selected from the selected resource group based on the constraint information 104 and the know-how information 105, and the resource n required first is selected for the actual work y selected first. (S4). For example, when selecting a model of a telephone, a catalog or the like required for it is selected as a resource.

In this way, the first work group x, the actual work y to be performed first in the work group, and the resource n required for this actual work y are selected, and the schedule work area 1
It is assigned to the schedule on 06 (S5). With the above, the first scheduling is completed, and the work of selecting the model of the telephone is selected as an actual work, for example, when installing the telephone. At this time, the constraint information 104 and the know-how information 10 are selected.
Based on 5, the scheduling is performed so that the one closest to the request can be selected in consideration of the function and price of the telephone.

Then, the first work group x is selected again (S1), and the actual work to be performed next is selected in the work group x (S2). For example, since the actual work is after selecting the model of the telephone, the purchasing work of the telephone is selected as the actual work. Then, the resource group corresponding to the actual work is selected as in the above-described processing (S
3) Further, the target resource is selected from the resource group (S4) and assigned to the schedule (S5). For example, if the purchase of a telephone is an actual work, people, money, etc. are selected as a resource group, and the person who purchases the telephone is selected from among them. In this way, the schedule allocation for the second time is completed, and, for example, the schedule allocation related to the purchase of the telephone is completed.

Then, the first selected work group x
The actual work to be performed next is selected (S2),
On the other hand, the processes of S3 to S5 are similarly performed. When the allocation of the schedules of all the actual work belonging to the first work group x is completed, the work group to be executed next time is selected. Then, from the first actual work to be executed in the work group, the actual work is sequentially selected according to the execution order / priority order as described above, and the processes of S3 to S5 in FIG. 2 are performed. In this way, work groups are sequentially selected according to the order of execution / priority,
For each work group, the actual work belonging to it is selected according to the execution order / priority order. Then, the processes of S3 to S5 of FIG. 2 are repeatedly performed for each actual work of each work group and assigned to the schedule. As a result, for example, in the case of installing a telephone, selecting the model of the telephone,
From the purchase and transportation of it to the selection of a telephone installation company and the actual installation of the telephone, the schedule of concrete actual work is assigned as a schedule, and the schedule result 1
It is output as 07.
