Abstract

A scheduling management system including a computer and a terminal device, and further containing a calculation unit to calculate the cost of work on the work target; a decision unit to decide if reorganization of the work schedule is needed or not; and a schedule generator unit to generate the work schedule; and in which the decision unit finds the progress of the work by comparing the work schedule with the work results, and decides if reorganization of the work schedule is needed based on the degree of divergence between the work schedule and the work progress; and the calculation unit calculates the work group cost generated by unifying the work groups for the combination of the work groups; and the schedule generator unit reorganizes the work schedule by comparing the calculated costs, and unifies the work groups based on results from the cost comparison.

Claims

1. A scheduling management system to generate a work schedule containing a plurality of work targets,

wherein the scheduling management system includes a computer, and a plurality of terminal devices coupled to the computer,

wherein the work targets are classified into work groups including at least one work target,

wherein the computer includes:

a storage unit that retains position information for the work target, a work schedule for the work target, and work results sent from the terminal device;

a calculation unit that calculates the cost of work for the work target based on the position information, the work schedule, and the work results;

a decision unit that decides if reorganization of the work schedule is needed or not based on the position information, the work schedule, and the work results;

a schedule generator unit that generates a work schedule based on the decision results from the decision unit and the cost calculated by the calculation unit,

wherein the terminal device includes;

a display unit that displays the work schedule sent from the computer;

an operating unit that enters the work results; and

a communication unit that sends the work results to the computer,

wherein the decision unit finds the progress of the work by comparing the work schedule with the work results and decides if reorganizing of the work schedule is needed or not based on the degree of divergence between the work schedule and the progress status of the work,

wherein the calculation unit calculates the cost for a unified work group formed from the work groups, for each combination of work groups when the decision unit decides that reorganization of the work schedule is needed, and

wherein the schedule generator unit compares the calculated costs and reorganizes the work schedule by unifying the work groups based on results from the cost comparison.

2. The scheduling management system according to claim 1,

wherein the schedule generator unit sets the priority of the work group combinations for unification based on results from comparing the calculated costs, and unifies the two work groups having a maximum priority level, and

wherein the calculation unit calculates the cost of the unified work group.

3. The scheduling management system according to claim 2,

wherein the schedule generator unit refreshes the priority of other work groups of the unified work group.

4. The scheduling management system according to claim 1,

wherein the work schedule includes the scheduled start time and scheduled end time for the work,

wherein the work results include the start time and the end time for the work.

5. The scheduling management system according to claim 4,

wherein the decision unit finds the work progress by comparing the scheduled start time and scheduled end time for the work contained in the work schedule, with the start time and end time contained in the work results.

6. The scheduling management system according to claim 1,

wherein the schedule generator unit unifies the work groups to achieve a minimum cost.

7. The scheduling management system according to claim 1,

wherein the calculation unit calculates the cost of the work group by summing the time required for the worker to perform work on the work target contained in the work group;

the time required for the worker to move between work targets contained in the work group; and

the time required for the worker to make a round-trip movement between the base and the work group.

8. The scheduling management system according to claim 7,

wherein the schedule generator unit unifies the work groups so that the cost for the one work group is within the work hours of the worker in charge of the work of the work group.

9. The scheduling management system according to claim 1,

wherein the calculation unit collects work targets whose work is completed and work targets whose work is being performed, into one work group, and generates a single initial work group for each work target whose work has not been started, and calculates the cost when the generated initial work groups are unified.

10. A scheduling management method to generate a work schedule including at least one work target,

the scheduling management system including a computer, and a plurality of terminal devices coupled to the computer,

the work targets being classified into work groups, and

the computer including a processor to execute the program and a memory to store the program,

the scheduling management method comprising:

a first step of accepting the entry of work results for the work schedule by the processor;

a second step of finding the work schedule progress by comparing the work results entered into the terminal device with the work schedule by the processor;

a third step of deciding whether reorganizing of the work schedule is needed or not by the processor, based on the degree of divergence between the work schedule and the work progress;

a fourth step of calculating the cost of the unified work group formed from the work groups for each combination of work groups by the processor when decided in the third step that reorganizing of the work schedule is needed;

a fifth step of comparing the calculated costs by the processor;

a sixth step of determining the combination of work groups for unification by the processor, based on results from the cost comparison; and

a seventh step of reorganizing the work schedule by unifying the work groups by the processor, based on the combinations that were determined.

11. The scheduling management method according to claim 10,

wherein in the sixth step, the priority of the combination of the work groups for unification is set based on results from comparing the costs;

and in the seventh step, the two work groups having a maximum priority setting are unified.

12. The scheduling management method according to claim 11,

wherein in the sixth step the priority of the work groups neighboring the unified work group are refreshed.

13. The scheduling management method according to claim 10,

wherein the work schedule contains the scheduled start time and scheduled end time of the work,

wherein the work results contain the start time and end time of the work, and

wherein, in the second step, the processor finds the progress of the work by comparing the scheduled start time and scheduled end time contained in the work schedule, with the start time and end time contained in the work results.

14. The scheduling management method according to claim 10,

wherein in the sixth step, the processor unifies the work group to achieve a minimum cost.

15. The scheduling management method according to claim 10,

wherein, in the fourth step, the processor calculates the cost of the work group by summing the time required for the worker to perform work on the work target contained in the work group;

the time required for the worker to move between work targets contained in the work group; and

the time required for the worker to make a round-trip movement between the base and the work group.
