Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preparing a process plan for work for achieving a certain purpose, for example, a process plan for constructing a nuclear power plant or the like.

[0002]

2. Description of the Related Art A process plan for plant construction includes an upstream process created at an early stage of the plan (constraining conditions for the downstream process such as the day when each floor is passed from the construction company to the manufacturer). It is roughly divided into two, downstream processes (detailed processes) created at the stage of advanced design. this house,
Since the downstream process is premised on that design information is available at the time of process creation, as a method for automatically creating a highly accurate process plan using a computer, for example,
As in Japanese Patent Laid-Open No. 4-48378, a method is used in which a necessary quantity is calculated from design information and a process plan is created based on the calculated quantity. On the other hand, since sufficient design information is not available when creating the upstream plan, the process plan was created based on human experience and intuition.

[0003]

Currently, there is a demand for streamlining and labor saving in plant construction, but in order to do the above more effectively, the upstream process that defines the constraint condition of the downstream process must be highly accurate. There is a great need to However, since the design information is not available when the upstream process is created, it is difficult to automatically create it by the conventional method.

An object of the present invention is to create a highly accurate process plan for construction even when all design information is not available.

[0005]

In order to solve the above problems, the present invention uses design information within the range obtained at that stage and precedent examples of buildings constructed in the past, even if not all design information is available. Therefore, the required quantity of each floor of the building is predicted, and the process plan is created accordingly.

[0006]

According to the present invention, a process plan can be created by predicting a necessary quantity even if all design information is not available.

Then, the information on the physical quantity for each floor is output to the work plan creation device 4.

Next, the work plan creation device 4 will be described in detail. The configuration of the work plan creation device 4 is shown in FIG.
First, the physical quantity of each floor is obtained by adding the physical quantities of the connecting devices obtained from the work data prediction apparatus 3 using the physical quantity calculation apparatus 4-1 of each floor and the floor division information 1-3. Next, the construction period of each floor is obtained by using the construction period calculation device 4-2 of each floor by multiplying the physical quantity of each floor by the basic unit in the information 2-3 of the relation between the physical quantity and the construction period. Next, the process plan 2 of the preceding machine
-4 replaces the construction period of each floor with the construction period obtained by the device 4-2, and the process plan is created by using the process plan adjusting device 4-3 by moving forward. After that, the plan information of the created process plan is output to the work information output device 5.

Next, the work information output device 5 will be described in detail.
