Abstract

PURPOSE:To prevent the generation of a trouble that the schedule of installing procedure is forced to be changed in a construction field by determining the installing by a specific procedure. CONSTITUTION:When the carrying route of an object is searched and the route exists, the object, an installing order, a restrictive condition to be the cause of the installing order determination, an index, the carrying route, and the installing position are stored with relation in a memory device and then displayed. When there is no carrying route because of interruption due to other object, a proposed correcting plan capable of correcting the order can be restricted by deciding whether the order of stored objects is determined by the restricting condition or the index. An object whose installing order is changed as compared to the uncorrected order is compared with the stored carrying route of objects replaced at their order and whether restricted order correcting plan can be realized or not is decide and displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for determining plant installation procedures using an arithmetic processing unit.

[Conventional technology]

Traditionally, installation procedures for equipment and piping within a plant have been determined by experts on a desk basis, based on equipment/piping layout drawings, data on the minimum unit of equipment/piping parts, etc., and judgment criteria regarding installation procedures. Ta.

On the other hand, in the field of layout design for plants and the like, a method for automatically determining piping routes is known, for example, as disclosed in Japanese Patent Application No. 58-187033.

[Problems to be solved by the present invention]

Conventional manual determination of installation procedures had the following problems.

(a) Whether or not a delivery route is secured for transporting the installation target to the installation location is determined by the expert in his or her head based on the drawings, and it is not necessarily the case that the delivery route is secured in reality. As a result, there were cases where the installation procedure had to be changed at the construction site.

(b) In the process of determining the installation order, if the delivery route is not secured, it is necessary to change the order, but in the past, this was done by trial and error, which resulted in poor installation efficiency.

Further, in the method of Japanese Patent Application No. 58-187033, automatic route searching is possible, but when a route cannot be found, it is necessary to change the order of route searching and perform the route searching again.

The purpose of the present invention is to:
According to the installation order automatically determined based on the judgment criteria, the presence or absence of a delivery route is automatically checked, and if a delivery route is secured, the delivery route is displayed, and if a delivery route is not secured, it is possible to install it. It is an object of the present invention to provide a method and a support device for supporting one procedure determination by presenting an order modification plan.

Means for Solving Problem C] The above problem can be solved by determining the installation procedure as shown below.

(1) Layout results of the installation target (installation position).

Installation object data (attributes such as size and type).

and installation procedure judgment criteria are stored in a storage device.

At this time, the criteria for judgment should be divided into constraints that must be followed and guidelines that should be followed if possible.

(2) Based on the above data, the objects to be installed are sequentially selected.

(3) Search for the delivery route of the selected object.

(4) If a route exists, associate the object with the installation order, the constraints or guidelines that determined the order, the delivery route, and the installation position, and store it in the storage device. is displayed on the display device.

(5) If the route does not exist because it is obstructed by another object, first check whether (a) the order was determined by the constraint conditions or by the guideline regarding the objects memorized up to that point. By determining whether the decision has been made,
Limit the candidates for amendments whose order can be corrected.

(6) In the limited order correction plan, select objects whose order has changed from before the correction from among each object and the objects that are about to be brought in, and By comparing the installation position and order of the objects that have changed, with the memorized delivery route for the objects that have changed, it is determined whether or not a limited order correction plan is feasible, and possible order corrections are made. Show suggestions.

(7) Update data regarding the installation order based on the order modification plan selected by the operator.

(8) Repeat steps (2) to (8) above until the installation order of all objects is determined.

[Effect]

In the present invention, when a delivery route cannot be secured, modification plans can be limited depending on the type of judgment criteria used to determine the order, and furthermore, each modification plan can be reconsidered based on the stored data of the delivery route and installation position. Since it is possible to determine whether or not a delivery route can be secured without searching for a delivery route, work efficiency in determining the installation order can be improved.

〔Example〕

Examples of the present invention will be specifically described below.

FIG. 1 shows an embodiment of the configuration of a plant installation procedure determination support device according to the present invention.
An image is displayed on the display screen of the image output device 4.

In order to display characters, input the data created with the calculation processing bag v12. For this process, the arithmetic processing device 2
Arithmetic unit 2a, processing procedure storage unit 2b, intermediate data storage unit 2
c, an image data output section 2d, and an input section 2e. The processing procedures stored in the processing procedure storage section 2b are sequentially called and executed from the calculation section 2a. - Figure 2 shows an example of the plant installation procedure determination method according to the present invention. !
! An example of the processing procedure executed in Embodiment 2 will be explained below step by step.

First, in processing step a, the layout results (installation positions) of objects to be installed such as building structure 2 equipment and piping in the plant, attribute data such as size and type of objects, and judgments regarding installation procedures are required for processing. The reference data is input into the storage device 15. At this time, data for 1 judgment criterion is divided into constraint conditions that must be observed and guidelines that do not necessarily need to be observed. Table 1 shows examples of criteria and their stored data.

Table 1 In the above table, the column "Distinction between constraints and guidelines" is indicated using numbers (or symbols) according to the following example.

For example, if device A is to be placed on top of device B, it is absolutely necessary to carry in and install device B before device A, and such a case is called a constraint condition.

In addition, if device A is installed at the entrance of a room and device B is installed at the back of the room, it is not impossible to install device A before device B, but it is necessary to bring in and install device B first. That is reasonable.

In this case, it is called a guideline.

In the content column of the table above, ¥A means that the numerical value A is a variable. L means the distance from the building entrance.

In the example shown in Table 1, two objects (device A and device B)
), the installation position and the distance to the delivery entrance are compared, and the one with the longer distance is given priority for installation.

Next, in processing step b, installation objects are sequentially selected based on the data input in step a.

This selection can be made, for example, by expressing the data as a predicate.

This is possible through processing using a symbolic processing language. The results are stored in the intermediate data storage section 2c (FIG. 1) in association with the object name, the installation order, and the criteria for determining the installation order.

In processing step C, the transport route for the object selected in processing step b is searched. At this time, energized objects installed in the previous order are treated as obstacles existing at the installation position.

If a carry-in route exists, processing step d is performed. In the processing step d, the installation position and delivery route are further added to the data of the object stored in the intermediate data storage unit 2c (FIG. 1) stored in step b, and the added data is stored in the storage device 6 (first (Figure). An example of data stored in Table 2 is shown.

Table 2 In the processing step e, the installation target object and the installation order are determined.

The reason for order determination, installation location, and delivery route are displayed on the image output device. A display example is shown in FIG. 3. In this example, the carry-in route of the objects whose order has already been determined and the carry-in route of the objects determined this time are distinguished and displayed.

If the carry-in route is obstructed by an object to be installed earlier and cannot be secured, process step f is performed. In the processing step f, a feasible order modification plan is created. Figure 4 shows an example of a detailed processing procedure.
-When trying to install in the order of C-E, 1
Let us consider a case where the delivery route for device E is blocked by device B and cannot be secured.

In the processing step f1, data regarding the objects 1 equipment A, B, C, and D whose order has been determined so far is retrieved from the storage device (Fig. 1).In the processing step fz, all candidates for order correction plans are retrieved. If the order of one device E and one device B to be restored is changed, the following six ways can be considered.

(Device A will be simply written as A, and will be written as B to E in the same manner below).

A-E-B-C-D A-C-E-B-D A-C-D-E-B A-E-C-B-D A-E-C-D-B In processing step f8, For each object, based on the reason data for determining the installation order, parts for which the installation order can be corrected are distinguished from parts for which the installation order cannot be corrected, and candidates for order correction plans are listed in a limited manner. Regarding the reason for determining the installation order from A to D retrieved from the storage device 6, only the part B-C is a constraint (absolute), and the other parts are guidelines (as much as possible... ), the order of B-C cannot be modified. In this case, A
-D is the only candidate.

In processing step f4, the feasibility of each of the limited candidates is determined. At this time, the following process is performed to avoid searching for a route again according to the order of the candidates. The characteristics of the delivery route are that even if the delivery routes interfere with each other, the delivery route can be secured (just by shifting the delivery time), and that the delivery route cannot be secured only when other objects are installed on the delivery route. It becomes possible. Therefore, if the delivery route is determined in the order x-y-z, then
To determine whether it can be converted to x-y, refer to the previous object Z
It is only necessary to determine whether there is interference between the installation position of the storage device i! and the delivery route of the objects Y and Z that came later. The installation position of object E stored in step 5 is compared with the coordinate data of the delivery routes of objects B, C, and D taken out in step fz to check for interference and determine feasibility.

In processing step g, a feasible installation order modification plan is displayed on the display device.

In step h, the operator selects an installation order plan to be executed from among the installation order modification plans and issues an instruction from the input device.

In processing step i, storage devices t! Update the data in 6. The updated data is the installation order and the criteria for determining the order.

〔Effect of the invention〕

According to the present invention, it is possible to prevent troubles such as being forced to change the plan of the installation procedure at the construction site due to a mistake in checking the delivery route, and also in the process of creating the installation procedure.

This has the effect of efficiently modifying the installation procedure when a delivery route cannot be secured.
