DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a construction work planning system according to the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is an explanatory diagram showing the hierarchical structure of the construction work. The construction work is composed of a plurality of collective works, each collective work is composed of a plurality of unit works, and each unit work is performed by a work group composed of a plurality of workers. Each unit work is composed of a plurality of element works, and each element work is performed by each worker. Each element operation is composed of a plurality of unit operations, and each unit operation is composed of a plurality of element operations.

[0009] For example, as shown in FIG. 2, the collective work constituting the construction work includes support installation, large-diameter pipe installation,
Installation of small diameter pipes, installation of air conditioners. The unit work constituting the support installation is carrying-in, centering, processing, and welding, and the unit work constituting the large-diameter piping installation is carrying-in, lifting, tacking, welding, and inspection. The installation of the large-diameter piping is carried out by the work team A, and the work team A
b, c, each worker performs element work. The unit operation performed by the worker c is, for example, to the mounting position, and the elementary operations constituting the mounting position include climbing to the rolling tower, putting on a safety belt, descending to the rolling tower, and so on.

FIG. 3 is a block diagram showing the configuration of the construction work planning system. As shown in FIG. 1, the construction work planning system 10 includes an input unit 12 for inputting work target information and the like.
And an operation unit 14 for performing an operation based on the input data;
A database 16 for storing data used for the calculation,
An output unit 22 for outputting the calculation result to the printer 18 and the display 20.

As shown in FIG. 4, the database 16 has a structure of each work hierarchy from the above-mentioned collective work to element operation, element work and construction equipment, unit operation and tool,
Data on the number of elementary work standard workers, the number of unit work standard work groups, work time variation parameters, worker combination patterns, and work group combination patterns are stored. In addition, information of the work target such as the name of the work, the work position, the quantity and the shape, the number of workers that can be input, and the start time of the collective work and the unit work are input to the arithmetic unit 14. At this time, the work target information may be automatically input from the CAD database 24 to the arithmetic unit 14 without being input to the arithmetic unit 14 by the manual operation of the input unit 12.

The calculation unit 14 calculates and outputs the required number of workers, the end time of the group work and the unit work, the operation rate, the basic unit, the work time, the construction equipment, and the tool operation rate based on the input data. Output to the unit 22. Next, the operation of the construction work planning system will be described. FIG. 5 is a flowchart showing the procedure of the work plan. First, the calculation unit 14 specifies a grouped work from the input information of the work target (Step 100). After specifying the united work, the operation unit 1
4 specifies the unit work, the element work, the unit operation, and the element operation constituting each collective work from the collective work configuration database 30 (step 110). The configuration from the unit work to the element operation is constructed as data as shown in FIG. Items shaded in FIG. 6 are data that have been input in advance.

After specifying from the collective operation to the element operation, the operation unit 14 reads the operation time variation parameter stored in the database 16 and calculates each element operation time (step 120). For example, the time required for the element operation of “climbing with a ladder” is calculated by a known method based on the number of working steps and the factors of work time fluctuation such as climbing with a chain block. After calculating the element operation time, the unit operation time is calculated by combining the element operation times (Step 130).

After the unit operation time is calculated, a unit operation combination is set from the configuration of the element work (step 140).
The element operation time is calculated by combining the unit operation times (step 150). When the element work time is calculated, the element work time chart 40 of a plurality of workers for each work group (only the work group A in FIG. 2) from the unit work configuration, the standard number of workers, and the worker combination pattern stored in the database.
Is created, and an element work combination of a plurality of workers is set from the unit work configuration, the standard work group number, and the work group combination pattern stored in the database (step 160). When the element work combination is set, the calculation unit 14 calculates a unit work time from the created element work time chart 40 and the element work combination (Step 170).

When the unit working time is calculated, the operation unit 14
A unit work combination is set from the configuration of the united work (step 180), and a united work time is calculated based on the start time of each unit work and each unit work time input to the arithmetic unit 14 (step 190). Usually, the united work time is calculated by simply combining the unit work times, so it is sufficient if the unit work time can be calculated.

When the total operation time is calculated from the element operation time, the amount of the object to be installed and the number of workers are input from the physical quantity database 32 to the calculation unit 14 (step 20).
0). The arithmetic unit 14 calculates man-hours / t based on the input data.
(Efficiency, productivity), work period, and operation rate are calculated (step 210). The man-hour / t is calculated from the amount of the object to be installed and the man-hour in the physical quantity database. The work period is calculated by creating a time chart of the work period as shown in FIG. 2 for each hierarchy of the work from the input start time of the collective work and the unit work.

Next, a method of calculating the operation rate will be described. FIG. 7 is a time chart showing the working hours of the workers a to d. The operating rate of the worker is calculated by dividing the time during which each of the workers a to d is performing the work by the time T during which the worker is performing the work. Also, the operating rate of multiple workers is
It is calculated by equation (1).

It is a time chart which shows the use time of No.-. The operation rate of each of the devices 1 to 4 is calculated by dividing the time during which the device is used by the time T during which work is performed.

FIG. 9 is a time chart showing the use time of the road tools 1-4. The operating rate of each road tool 1-4 is
It is calculated by dividing the time during which the tool is used by the time T during which work is performed. As shown in FIG. 10, when the work place is divided into a plurality of areas 1, 2, 3,..., N, the calculation is performed for each area according to the procedure shown in FIG. The results are evaluated according to the evaluation items. The evaluation items are the equipment operation rate, the tool operation rate, and the worker operation rate at the element work level, and the apparatus stack, the tool stack, and the worker stack at the collective work and the unit work level.
This makes it possible to adjust the number of workers, devices and tools to be put into each area.

As described above, according to the construction work planning system of the present invention, the first time required for the element operation is obtained, and the second time required for the unit operation is obtained based on the first time. The third time required for the elementary work is determined based on the combination pattern of the unit operations belonging to the elementary work and the second time, and the fourth time required for the unitary work is determined based on the combination pattern of the elementary works belonging to the unit work. By calculating based on the third time, the work plan of the construction work from the element operation to the unit work can be accurately performed.
