Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention provides a method for determining the work schedule of each construction work section in a plant that is a large-scale structure and whose construction takes a long time. This invention relates to a plant construction process management support system that appropriately manages plant construction process management.

BACKGROUND OF THE INVENTION Many construction process management systems currently exist that support the input, confirmation, and adjustment of schedules. The information obtained with such a construction process management system is a schedule corresponding to the work name, such as a line drawing schedule, and the only correspondence with the object to be built is the abstract image obtained through the work name.

On the other hand, with the development of computer utilization technology, design systems using computers (:, A D (Computer
Aided Design) systems are widely used.

In this CAD system, information regarding each component constituting a structure, such as the name, position, shape, etc. of each component, is set within the range necessary for its design.

The information obtained is visual information about the structure and form of the component.

(Problem to be solved by the invention) In general, in large-scale structures such as plants, for example, how to carry out the general process, by what time should walls and floors be built, and when should major components be installed? The construction process is divided and set, such as when to install piping, etc. in each construction work zone. For example, when installing a major component, it is necessary to confirm that the route for transporting the component is secured, that the component is properly secured at that time, and after these checks, the specific work must be carried out. Calculate the number of work days taking into account the procedure, check the work space at that point, and check for interference between tasks being performed in parallel. This kind of confirmation work needs to be done on a desk, but this work actually becomes a considerable burden.

In addition, since large-scale construction works such as this generally require a large amount of resources, in order to avoid resource loss,
! The construction process management system is equipped with a process readjustment function. However, even with this process readjustment function, the original schedule is usually strictly adhered to.

This invention was made in consideration of the above circumstances,
The purpose of the present invention is to provide a plant construction process management support system that can reduce the burden of setting each process when setting the construction process of a large-scale structure such as a plant, and can easily and reliably set the construction work schedule.

(Structure of the Invention) (Means for Solving the Problems) This invention is a process of inputting various databases, extracting objects existing in an arbitrary construction work zone, and setting and correcting a work schedule for the construction work zone. This system is characterized by having a management system and a CAD system connected to this process management system and simulating and displaying a work schedule created by this process management system in three dimensions.

(Operation) Therefore, according to the plant construction process management support system according to the present invention, first, the process management system is used to extract items existing in a given construction work area, and standard work is performed to install and assemble those items. Complete the schedule. Next, a CAD system is used to three-dimensionally simulate and display the construction work in accordance with this standard work schedule.

Based on this three-dimensional display result, the work schedule is corrected using the process control system to complete the actual work schedule. In this way, the actual work schedule is supported while taking three-dimensional correspondence with objects.

(Example) Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram showing an embodiment of a plant construction process management support system according to the present invention.

The plant construction process management support system 1 includes a process management workstation 2 as a process management system, and a C A D connected to this process management workstation 2.
(Computer Aided Design) system 3 and a database 5 connected to the process control workstation 2 via a database management system 4.
, a display device 6 and an input device 7 connected to a process management workstation 2 and a CAD system 3. The display device 6 is, for example, a CRT (Cath
The input device 7 is a pointing device such as a mouse or the like.

CAD System 3 has a built-in CAD database,
A database management system 4 is also connected to this CAD database. The database 5 stores a process attribute database, a standard process database, a sequence database, and the like.

The CAD database stores information regarding objects such as walls and equipment existing in each construction work section for constructing a large-scale building such as a plant. For example, the information includes the name, position, shape, quantity, and object M of the object. Further, the names of objects can be organized into equipment (pumps, etc.), piping, ducts, etc. by focusing on structure, for example. Also, by organizing the items according to the system to which they belong, they can be organized into xX system pumps and Xx piping. Furthermore, the amount of material is only XX tons for piping, for example.

The process attribute database stored in the database 5 stores, for each construction work zone, information regarding the attributes of objects within the construction zone. This information includes, for example, the name of the object, the scheduled start date of construction, the scheduled completion date of construction, and the material that affects the number of construction days. In addition, the standard construction period database stores, for each construction work section, the names of objects in the construction section, rate coefficients, construction constraints, and the like. The coefficient of yield is the average amount of work for the material, and is an empirical value. For example, the coefficient of yield in piping is -
This value means that XX tons of construction work can be done per person per day.

The sequence database is information that is input and stored at the stage when the process management workstation 2 creates a standard work schedule for each construction work section from the above-mentioned respective databases, as will be described later.

The contents of this information include, for example, the names of the objects existing in the construction work zone and the standard work schedule of the objects.

The information from each of the above databases is input by the designer to the input device 7.
By operating the database management system 4 via the process control workstation 2, the search function of the database management system 4 searches for the information and displays it on the display device 6.

Now, the process control workstation 2 extracts objects existing in a given construction work zone from each of the above databases via the database management system 4, sets a standard work schedule for that construction work zone, and sets the standard work schedule for the construction work zone. It has the ability to modify the schedule and set the actual work schedule.

In other words, when creating the tabular work schedule 10 shown in FIG. 3, the process management workstation 2 uses the system name of the objects existing in each construction work zone from the CAD database as in step 1 of FIG. Extract and list. Furthermore, the process control workstation 2
The total material value as physical quantity is extracted from the AD database, the rate and coefficient are extracted from the standard construction period database, and the construction start date, etc. are extracted from the process attribute database and displayed in each column of the work schedule 10 in tabular form.

Next, the process control workstation 2 sets the amount of work for each system in the tabular work schedule 10 based on the designer's operation using the input device 7, sets the number of inputs, and Display in the specified column. Then, the process control workstation 2 calculates the required construction period for each system from the material total value, the step rate coefficient, and the number of input workers, and displays it in a predetermined column in the work schedule 10 in tabular form. Roughly speaking, the process management workstation 2 calculates the construction completion date based on this required construction period and similarly displays it. In this way, the process control workstation 2 completes the standard work schedule for each construction work section, as in step 2 of FIG.

Upon completion of this standard work schedule, the process control workstation 2 stores, for each construction work zone, the name of the construction work zone, the name of the object in the construction zone, and the work schedule of that object ( (date and time, etc.). Thereafter, the process control workstation 2 causes the display device 6 to display a process chart 11 and a man-hour accumulation table 12 in a parchart format as shown in FIG. 3 based on this sequence database.

The man-hour accumulation table 12 shown here is a bar graph showing the number of people required for each month.

The CAD system 3 searches the sequence database by the designer operating the input device 7, searches the CAD database based on the system name of an arbitrary construction work zone obtained from this sequence database, and searches the CAD system for the system name. The construction work is simulated three-dimensionally by obtaining the shape data of the object corresponding to the object, and the progress of the construction work is visualized (Step 3 in Figure 2). Therefore, for example, when a date and time is specified, the progress of construction work at a certain point in time can be confirmed, and the construction work to be performed during a certain period can be confirmed concretely. Furthermore, when an arbitrary construction process section is specified, the work status of each different system in that construction process section can be visually confirmed along the time axis, and spatial interference between each work can be confirmed.

The process control workstation 2 corrects the standard work schedule displayed in the tabular work schedule 10 as shown in step 4 of FIG. 2 through the operations of the designer who visually confirmed the standard work schedule using the CAD system 3. and complete the actual work schedule. For example, by changing the order of work in the standard work schedule, work on XX will be carried out after work on YY is completed.
By replacing the individual elements in Table 10, an actual work schedule is created.

According to the above embodiment, first, the process control workstation 2 creates a standard work schedule, and the CAD system 3 three-dimensionally simulates and visualizes this standard work schedule.

The designer determines the suitability of the three-dimensionally simulated standard work schedule, corrects inappropriate parts, and completes the actual work schedule. Therefore, the burden of creating a construction work schedule can be reduced, work can be prevented from being overlooked, and the construction work schedule can be easily and reliably set.

〔Effect of the invention〕

As described above, according to the plant construction process management support system according to the present invention, various databases are input, objects existing in a given construction work zone are extracted, and a work schedule for the construction work zone is set and corrected. Since it has a process management system and a CAD system that is connected to this process management system and three-dimensionally simulates and displays the work schedule created by this process management system, it is possible to Since the construction work schedule can be visually confirmed and set while taking correspondence three-dimensionally, the construction work schedule can be set easily and reliably.
