2. Description of the Related Art Conventionally, plant construction process evaluation has been performed by displaying a time-series installation situation of parts to be constructed in accordance with a process plan. That is, for each work item of the process plan, for example, if the work type of the item is “installation”, the three-dimensional model of the work target component included in the item between the work start time and the work end time of the item is calculated. The process of displaying at each installation position is performed.

The evaluator of the process plan looks at the installation status as described above to determine when, where, which work target component will be installed, and the surrounding conditions of the installation place at the time of installation (what Understand how much is already installed, etc.). Then, the validity of the process plan is examined based on the situation, and the process plan is modified in some cases.

Further, in various evaluations using computer graphics, for displaying the situation of workers and the like, for example, "the layout evaluation of the work space by the virtual subject" announced at the 48th National Convention of the Information Processing Society of Japan. As described above, there is one in which a human is displayed as a comparative object for evaluating the workability of a human with respect to an evaluation target and displaying the situation (size, etc.) of the evaluation target in a more understandable manner.

[0005]

In the above prior art, only the status of the work target parts is displayed, but in the actual construction work, not only the status of the work target parts but also the status of the worker performing the work is important. It is an element.

In the above-mentioned conventional example in which the human situation is displayed at the time of evaluation, the human display is merely an auxiliary, and it is not possible to change the display timing or display position according to the process plan.

Therefore, an object of the present invention is to display the situation (work time, work position, etc.) of each worker in an easy-to-understand manner in a construction simulation according to a process plan.

[0008]

In order to solve the above problems, according to the present invention, a work space is set in a work target part of each work, and a marker indicating the situation of a worker who works in the work space is provided. According to the information held by the worker, the form is changed and displayed.

[0009]

According to the present invention, the time-series distribution of each worker can be displayed by displaying the time-series condition of the worker according to the process plan.

No. is a serial number of information for each work item. The plant code is an identification code for determining which plant the process plan is for constructing. Area No. is an identification code of an area in which the work of the work item is performed. The type of work target component is information for identifying the type of the component that is the target of the work performed in the work item, and is selected from the categories shown in FIG. The type of work is information for identifying the content of the work, and is selected from the categories shown in FIG. In FIG. 4, "general" means that the target parts are small in scale, and therefore all the operations for the parts are summarized in one item.
The work start time is information on the date when the work is started. The end time of work is information on the date when the work must be finished. The man-hour of work is information on the man-hour required for carrying out the work (the number of workers required per day × the number of work days). The type of job type to perform work is information for identifying the type of job type to perform work, and is selected from the categories shown in FIG. The device number of the three-dimensional design information of the work target component is information of the device number of the three-dimensional design information used for associating the work item with the three-dimensional design information of the work item.

Next, the three-dimensional design information storage device 2 will be described in detail. In this system, three-dimensional design information is recorded in a format as shown in FIG. 6 for each part of each work unit of plant construction. Each item in FIG. 6 is information having the following meanings.

No. is a serial number of information for each component. The plant code is an identification code for determining in which plant the part is used. The equipment number is information for identifying a part, and the equipment number is recorded for each work item of the process plan to identify the correspondence between the process plan information and the three-dimensional design information. Area No. is an identification code of an area in which parts are installed. The equipment origin position is the coordinate of the center point of the component on the X, Y, Z coordinate system set for the entire plant (unit is millimeter). The rotation angle is X, which indicates how much the actual installation direction deviates from the basic direction of the part.
It is represented by an angle of deviation from each of the Y and Z coordinate systems (unit is degree).

In this system, the three-dimensional shape of each part is defined as an aggregate of three-dimensional basic figures such as a cube, a cylinder and a sphere. Therefore, it is necessary to record as many pieces of information about basic figures as the number of basic figures that make up the shape of a part. The information of the basic figure is composed of information having the following meanings.

The basic figure number is a number indicating the type of basic figure, and as shown in FIG. 7, there are three types of rectangular parallelepiped, column, and sphere. The basic figure origin position is the coordinates of the center point of the basic figure on the X, Y, Z coordinate system set so that the origin point of the device is the origin (unit is millimeters).

The three-dimensional design information of the work space of the work item is calculated using the three-dimensional design information and the work space setting rule obtained from the work space setting rule storage device 3. Further, the man-hour of the work item is divided by the number of days of the work period to calculate the number of workers per day. Then, the position of the first worker is set on the floor of the work space so as to occupy 1 square meter per person, and the three-dimensional information of the marker as shown in FIG. 10 indicating the worker is set at that position. It is determined whether the marker interferes with an existing marker indicating another worker or a work target component already installed at that stage. The position of the member is newly set, and the process is repeated until a position that does not interfere can be set.
At this time, if the markers for the number of people could not be set even though all areas on the floor were examined,
Display that the man-hour is too much for the work area,
Suggest to modify the process plan itself. If there is no interference with others and the marker can be set, the marker of the next worker is set. The above process is repeated to set markers for the number of people.
