PURPOSE:To select a preferable answer in the allowable width of an executable time band by providing the plan restriction canceling system with a restriction canceling engine for finding out a time band generating no contradiction in the set of time bands for generating the task start of a task stored in a task proposing memory and the set of time bands for generating task end based upon the task execution order. CONSTITUTION:The restriction canceling engine 4 refers a task attribute memory 1 and a task order memory 3 and finds out a time band generating no contradiction in the set of time bands generating the task start of a task stored in the task proposing memory 2 and the set of time bands generating task end based upon the task execution order. The above processing is repeated until the start time band and the end time band are respectively stabilized. Consequently, the start enabled time band and the end enabled time band of the memory 2 become answers not to contradict restricting conditions. Thus, a preferable answer can be selected in the allowable width of the executable time band. |
