Abstract

PURPOSE:To confirm the actual condition of construction advancement by extracting a plant constituting element where the construction sequence is set from a data base with the designation of attribute data, setting the construction advancing condition and executing display based on the time attribute and sequence provided on the plant constituting element. CONSTITUTION:Based on a data base DB 1 storing the data of the plant constituting element provided on a CAD system, a system for supporting the control of a plant construction process is mainly constituted of a construction sequence setting function 2, a display function 3 and a construction advancing condition setting function 4. The advancing condition setting function 4 extracts the data from the CAD-DB in correspondence to the request of a user and displays the data on a display device such as a CRT. Afterwards, the advancing condition is registered to the element successively selected on a screen by an element selecting means such as a mouse. When the connecting relation of the respective constituting elements is defined by the CAD system, the construction advancing condition can be easily set by selecting the mouse, etc., such as the selection from the element A to the element B by following the connecting relation. Thus, the advancing degree of the construction process can be practically recognized.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention supports construction process management of large-scale buildings such as plants, which requires schedule management of each construction work over a long period of time. Related to systems (prior art) Many process management systems (programs, etc.) have existed to date, and these support input, confirmation, and adjustment of schedules. Basically, the information you can get here is
It is a schedule for each task, or in other words, data for delineating the lines, and the only correspondence to what is originally intended to be made is the image obtained through the name of the task.

On the other hand, with the advancement of computer technology, computer-based design systems (CAD: Computer
A1dcdDesign) has become widely used.

In such a CAD system, information regarding each component, such as the name, position, shape, etc. of the component, is set to the extent necessary for the design. The main information obtained here is visual information such as what kind of structure and form the structure has, and in a sense, it is information such as what the finished product will look like.

During the construction period, we are following up on the actual construction status based on these systems.

(Problem to be solved by the invention) In large-scale buildings such as plants, for example, walls,
The process is divided into steps such as setting a rough outline of the major process such as the floor, installing the main components at the next level, and installing piping, etc. for each section at the next level. In the installation of major components, for example, it is necessary to confirm that the delivery route is secured, that the component is secured at that time, and at a lower level, it is necessary to take into account specific work procedures. It is necessary to consider tasks such as calculating the number of working days, checking the work space at that point, and checking for interference between parallel tasks. Similar consideration is required when rescheduling due to construction delays, which actually results in a considerable workload. In general, large-scale construction works like this require a large amount of resources, and it is difficult to avoid the loss of resources and to grasp the actual progress of the construction work, so it is important that the process management system has a process readjustment function. However, it is common to respond by strictly adhering to the original schedule. However, even if such measures are taken to strictly adhere to the schedule, it is important for management to understand the progress of the construction work in a more concrete manner.

The present invention has been made in response to this problem, and it is an object of the present invention to provide a plant construction process management support system that can set and confirm the actual construction progress status.

[Structure of the Invention] (Means for Solving the Problems) The plant construction process management support system of the present invention includes a database that stores data on plant components, and a construction sequence setting that sets construction sequences for each of the plant components. a display function that displays along a time axis based on the time attribute and sequence that the plant component has; and a display function that extracts the plant component to which a construction sequence is set from the database by specifying its attribute data. It is characterized by having a construction progress status setting function for setting the construction progress status.

That is, the plant construction process management support system of the present invention uses, for example, the following database (DB).

CAD-DB: Component name, position, shape,...
Attribute DB: Attributes of component elements, such as name, scheduled construction date,
Scheduled completion date, progress status (red, under construction, completion date, etc.)... Standard construction period DB: Component name, standard construction period, construction constraints,
... Sequence DB: Process name, element-1, work schedule of element-1 (time etc.), element-2, work schedule of element-2, ... The means to access these DBs is DBMS (Data
Base Management System
It has been generalized as m). Then, based on these DBs, for example, the following means are used.

(b) By specifying attribute values such as spatial area, sequence, system name/component name, date and time, progress status, etc.
Means for extracting and displaying constituent elements from AD-DB.

(mouth) A means of selecting a component from a display screen using a pointing device such as a mouse.

(c) A means for setting data (date and time, etc.) in the selected component.

(2) Means for displaying along the time axis based on the time attributes and sequences of each component.

The above-mentioned means have also become popular due to advances in CAD technology and computer technology such as workstations.

(Function) The progress status setting function in the plant construction process management support device of the present invention extracts data from the CAD-DB according to the user's request, displays it on a display device such as a CRT, and then extracts data from the CAD-DB and displays it on a display device such as a CRT. The progress status is registered in the elements sequentially selected on the screen. Construction is progressing as planned.
If the construction schedule for the day is set, it is possible to visually check the image and set the progress status of each element in an extremely easy way. Items with process delays can be extracted using simple conditions such as ``Items have not been completed even though the scheduled completion date has passed'' and can be set using the same procedure. Can be done at the same time.

Since data from the CAD system is used, if the connection relationships of individual components are defined there, by tracing the connection relationships, you can easily check the construction progress status by selecting elements such as element B from element B using the mouse. Can be set.

(Example) An embodiment of the present invention will be described below.

Fig. 1 shows the general functional configuration of the plant construction process management support system of the present invention, which mainly uses the construction sequence setting function 2, the display function, and the It is composed of a function 3 and a construction progress status setting function 4.

The database 1 sequentially stores data such as the construction schedule, standard construction period, construction constraints, and work schedule for each component set by the construction sequence setting function 2 as attribute values of the plant components. The display function 3 extracts data from the database 1 in response to a request and displays it on a display device such as a CRT, and can display data along the time axis based on each time attribute and sequence. The construction progress status setting function 4 sets the current construction progress status for the plant components extracted from the database 1 and displayed on the screen by specifying attribute values, and
The basic user operation is to constantly look at the shape displayed on the screen and set data such as ``This is finished'' or ``This will require construction.'' Just go.

Interaction during this time can be realized using techniques such as window systems and menu selections that are frequently used in workstation environments.

The construction progress status is set, for example, by the procedure shown in FIG. First, the spatial scope is determined by selecting the construction area, target system, etc. (5). Next, attribute data on the construction schedule and progress status for the components in the set range are extracted from the database 1 (6), and the construction work that should be completed, started, or under construction within the specified time range is extracted. Narrow down the components from the attributes of the situation (7
), the shape data of the constituent elements within that range is extracted from the database 1 (8). Items that have already been completed, items that are unfinished beyond the scheduled date, etc. are displayed in a predetermined color so that they can be distinguished (9), and the progress status is set in response to element selection using a mouse, etc. and save it in database 1 (10). Repeat the above operations as necessary.

As explained above, using a pointing device such as a mouse, you can visualize the construction process and the work involved.
The actual construction progress status can be easily set while looking at the image of the construction object.

゛ [Effects of the Invention] As is clear from the above explanation, the plant construction process management support system of the present invention can concretely grasp the progress of the construction process, and can be used from process setting to actual completion of construction. can graphically support schedule management.
