2. Description of the Related Art In order to efficiently and smoothly carry out construction work, it is very important to set work procedures and the number of man-hours, and various construction planning methods have been proposed. One of the typical techniques is a PERT (Program Evaluation) described in "PERT / CPM" by Tomoaki Sekine (Nikkagiren).
and Review Technique), CPM (Critical Path Meth)
od). In these methods, a process network indicating the order relation of each operation is created, and the process networks are accumulated to set the overall process.

Conventionally, there are a Gantt chart and a network diagram as a method for displaying the planned work process. In the Gantt chart, the horizontal axis represents time (process), the vertical axis represents various production equipment and work, the work start date and time of each work,
And the end date and time so that they can be seen at a glance.
On the other hand, the network diagram is represented by arrows indicating the work and connection points indicating the connection relation of the work, and expresses the order relation of the work in an easy-to-understand manner. In particular, it is widely used in a method in which a work process is represented by a computer using a method such as a PERT method or a CPM method.

[0004]

However, in the method using the Gantt chart, it is difficult to understand the order of the work even if a computer is used. On the other hand, in the method using the network diagram, the relation between the work time and the work is also difficult. There was a problem that it was difficult to understand. In particular, when the planning scale of the work process becomes large, the number of work increases, and the constraints such as the work order relation are complicated, the lines representing the interrelationship of the work become complicated in the network diagram, and the work process There has been a problem that a great deal of effort is required to create, modify, and review.

[0005] The present invention has been made in view of such circumstances, and solves the conventional disadvantages, even in a work process in which the plan scale of the work process is large and the constraints of the work are complicated, the conventional Gantt. Based on charts and network diagrams
It is not necessary to clarify the order of work
Another object of the present invention is to provide a work process display device that can easily correct the work process.

FIG. 5 is a table showing a part of data stored in a calculation result storage unit 36 provided in the computer 12 of the work process display device 10. The calculation result storage data is a combination of the data shown in FIG. 4B and the calculation result storage data shown in FIG. This data is obtained by calculating the data of the process network structure data unit 32 in the block diagram of FIG. 1 according to the procedure stored in the operation procedure storage unit 34 in the output unit 14 in a format capable of displaying the process diagram. Is stored. The calculation method stored in the calculation procedure storage unit 34 is, for example, a commonly used PERT method. Here, each work a, b,
c. . . n, the work start time and the work completion time are stored including the earliest start time and the latest completion time obtained by the PERT calculation, in addition to the numerical values obtained by replacing the X coordinate and the Y coordinate on the display device. It is.

FIG. 6 shows an example of a display when the constraint display function 62 is selected in the flowchart of FIG. For example, by designating the work i to be displayed as the constraint condition of the B system, the preceding work e and the event condition 2 that must be completed to start the work are identified and displayed. As a method of identifying and displaying these, in addition to the display example, it is good to use a method of distinguishing and displaying by using the brightness, color, blink, etc. of a line or a diagram representing the work, or a method of displaying only related items. .

These operations can be performed based on the work information stored in the calculation result storage unit 36 and shown in the table format shown in FIGS. 4B and 4C. According to the constraint condition display example shown in FIG. 6, for example, there is no preceding work of the work a of the system A, and there is an event 1 as the preceding event constraint.

FIG. 7 shows an example of a display when the process is corrected in step 66 in the flowchart of FIG. 2 and the process correction display function is selected. By designating the work to be corrected, the time at which the work can be started earliest and the range at which the work can be completed latest are displayed. According to the display example, according to the calculation result storage data shown in FIG. 5, for example, time 9 is the earliest start time for work i, and time 16 is the latest start time for work i. Is displayed in the sense that it can be moved to.

As a method of displaying the movable range of the correction work, it is desired to display the work together with the work to be corrected as shown in the figure, or to display the earliest start time and the latest start time directly by numerical values to make a correction. The work start time may be input. These operations can be performed based on the information shown in the table of FIG. 5 stored in the calculation result storage unit 36 shown in the block diagram of FIG. For example, as the stored data shown in the table of FIG. 5, the work a has a work start time of time 1 and a work completion time of time 3 on the display device. On the other hand, the earliest start time is time 1 and the latest completion time is movable from time 4 by time 1.
