Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work management system which receives a work instruction for a work consisting of a plurality of processes, expands the work instruction for each process, adds a work priority, and outputs the work priority to a work site.

[0002]

2. Description of the Related Art Generally, in a work consisting of a plurality of processes (such as a manufacturing work), it is necessary to instruct a work to be carried out in each process of a work site for a certain period of time, and collect and manage work results. A work management system for constructing these work instructions and work results management is constructed. Further, in such a work management system, it is strongly required to support efficient operation of the work site and also effective operation of the factory or the entire corporate organization. Therefore, the work management system needs to send a work instruction in which priority is added to the work of each process to the work site in order to meet the request.

Conventionally, this type of work management system is a means for calculating the work priority to be added to a work instruction, in the order of the earliest delivery date of the process, the longest lead time of the process, the earliest of the last delivery date, and the next process. The work priority was calculated based on the conditions (static conditions) that can be grasped at the time of work instruction planning, such as the order in which the number of processes is large.

That is, the conventional work management system takes into consideration only the above-mentioned static condition as the calculation standard of the work priority, and changes in the progress of the work at the actual work site,
For example, a work related to a predetermined work in a predetermined process (a work performed in the same process as the predetermined work and performed before the predetermined work) is delayed, and a work related to the post work is concerned. Work in progress (waiting for start) or load status (corresponding process necessary to complete the work) that is performed in the same process as the predetermined work and is performed prior to the predetermined work The implementation time) was not taken into consideration.

Further, in the actual operation at the conventional work site, the site worker and the supervisor look at the work progress status, the work in progress status, and the load status in relation to the work being executed, and make a situation judgment. That is, in addition to the work priority assigned by the static condition, the work site worker and the supervisor have modified the work priority after determining the dynamic condition.

[0006]

However, in an actual manufacturing site, due to various factors, the progress of the work may be delayed or too advanced from the original work schedule.
On the other hand, as described above, the conventional work management system does not take any measures against the delay or excessive progress of the work.

Therefore, if the work order is simply decided based on the work instructions given by the work management system in the actual work, the progress of the work of the pre-relationship is delayed for the work and the work is Although there is a situation in which it is not possible to start work, there are cases where the work set-up for the work is started, and there is the disadvantage of wasting man-hours.

[0008] Further, even if a certain work is delayed in progress of the related work behind the work schedule and a large number of works in a work-in-progress are generated, by continuing the execution of the work, There is a case in which the work related to the work in progress may be further increased, resulting in a decrease in work efficiency.

The present invention eliminates the above-mentioned conventional drawbacks and feeds back and refers to dynamic conditions such as a progress status of a work related to the work instruction information and a load status of the work related to the work instruction information. The purpose is to provide a work management system that calculates the priority of the work instruction information so that efficient work can be performed at the work site and efficient operation can be realized as a factory and the entire corporate organization. To do.

As described above, the work instruction information, which has been expanded according to the process and added with the priority, is delivered to the work site 30. As described above, the priority added to the work performance information is calculated in consideration of dynamic conditions such as the progress status of the work related to the work related to the work performance information and the load status of the work related to the post work. Therefore, even if the work at the work site 30 is delayed or too advanced from the work schedule due to various reasons, the situation is fed back to the work management system 20 and reflected in the priority added to the work instruction information. You can

Although the present invention has been described with reference to the preferred embodiments, the present invention is not necessarily limited to the above embodiments. For example, in this embodiment, the progress management unit 23
The status added to the work instruction information for managing the progress of each work is expressed in four stages of “work in progress”, “start”, “stagnation”, and “completion” according to the progress of the work. Instead of such an expression, it may be expressed as a percentage in which the unstarted state is 0% and the completed state is 100% according to the progress of the work. In this case, the progress management unit 23 sequentially updates the status according to the progress of the work until the status of the work information reaches 100%, and the status of certain work instruction information is 100%.
In case of, the status of the work instruction information regarding the post-related work concerned is newly managed as 0%.
The load status management unit 24 also extracts work instruction information whose status is less than 100% to calculate the load status.

Further, when calculating the priority of the work instruction information, the work instruction management unit 25 always checks both the progress status of the pre-related work and the load status of the post-related work related to the work instruction information. You don't have to consider it. That is,
The priority of the work instruction information can be calculated in consideration of either the progress status of the work related to the work related to the work instruction information or the load status of the related work. Even in this case, the progress of the work at the actual work site 30 can be sufficiently reflected as compared with the conventional case in which the priority of work information is determined without considering any dynamic condition. .

In this embodiment, the work management system 2
Although the manufacturing work has been described as an example of the work consisting of a plurality of processes managed by 0, it goes without saying that the present invention can be similarly applied to the work consisting of a plurality of other processes.

[0034]

As described above, according to the present invention,
It is possible to feed back and refer to the progress status of the work in the pre-relationship of the work related to the work instruction information, which is a dynamic condition, and refer to it to reflect it in the calculation of the priority of the work instruction information. For this reason, when the progress of the pre-related work is behind the scheduled work and the work cannot be started, the setup of the work is not started and wasteful man-hours are wasted. It is possible to avoid the situation. Therefore, there is an effect that efficient work can be performed on the work site, and efficient operation can be achieved as a whole of the factory and the corporate organization.

Further, according to another work management system of the present invention, the load status of the work related to the work related to the work instruction information which is a dynamic condition is fed back and referred to, and the line of the work instruction information is displayed. It can be reflected in the calculation of freshness. Therefore, when the progress of related work after a certain work is behind the work schedule and there are many work in progress, the execution of the work is interrupted and the other work is given priority. By doing so, it is possible to reduce the work related to the post-working state. Therefore, there is an effect that efficient work can be performed on the work site, and efficient operation can be achieved as a whole of the factory and the corporate organization.

Further, according to another work management system of the present invention, both the progress status of the work in the pre-relationship and the load status of the work in the post-relationship related to the work instruction information which is the dynamic condition are fed back. Can be referred to and reflected in the calculation of the priority of the work instruction information. Therefore, there is an effect that more efficient work can be performed on the work site, and more efficient operation can be realized as a factory and a corporate organization as a whole.
