Abstract

A task management system for executing a task selected from tasks structuring a task combination, includes a judging unit for judging whether there is a task combination switchover request or not, a switchover unit for switching over the task combination after completing an execution of a specified task in the tasks structuring the task combination before the switchover when judging that there is the switchover request, and an execution unit for executing the task selected from the tasks structuring the task combination switched over by the switchover unit.

Claims

1. A task management system for executing a task selected from tasks structuring a task combination, comprising:

a judging unit for judging whether there is a task combination switchover request or not;

a switchover unit for switching over the task combination after completing an execution of a specified task in the tasks structuring the task combination before the switchover when judging that there is the switchover request; and

an execution unit for executing the task selected from the tasks structuring the task combination switched over by said switchover unit.

2. A task management system according to claim 1, further comprising a storage unit for storing an associated relationship between the task structuring the task combination and an identifier for identifying this task with the specified task.

3. A task management system according to claim 1, wherein the specified task is a task of which a process completion is requested when switching over the task combination.

7. A task management system according to claim 2, wherein the specified task is a task of which a process completion is requested when switching over the task combination.

4. A task management method of executing a task selected from tasks structuring a task combination, comprising:

a judging step of judging whether there is a task combination switchover request or not;

a switchover step of switching over the task combination after completing an execution of a specified task in the tasks structuring the task combination before the switchover when judging that there is the switchover request; and

an executing step of executing the task selected from the tasks structuring the task combination switched over by said switchover unit.

5. A task management method according to claim 4, wherein said switchover step involves, when judging that there is the switchover request, switching over the task combination after completing the execution of the specified task identified by an identifier in a storage unit for storing an associated relationship between the task structuring the task combination in the tasks structuring the task combination before the switchover and an identifier for identifying this task with the specified task.

6. A task management method according to claim 4, wherein the specified task is a task of which a process completion is requested when switching over the task combination.

8. A task management method according to claim 5, wherein the specified task is a task of which a process completion is requested when switching over the task combination.
