<p><P>PROBLEM TO BE SOLVED: To solve the problem in a conventional process planning that the necessary construction period from start to completion of construction on a process plan is determined by building up times necessary for individual works, and when the construction period desired by a consumer is shorter than the necessary construction period, the process plan is corrected by trial and error. <P>SOLUTION: To enable the systematic correction of the process plan in a case that the desired construction period is shorter than the necessary construction period, parallel work attribute information showing whether each process is workable in parallel or not and order replacement attribute information showing whether the work order of each process is replaceable or not are assigned to routing data 2. When a correction of the process plan such as shortening of the construction period is needed, it is examined whether the attribute information of each process is ON or OFF, and processes which are ON are preferentially selected, and set as a parallel work, or the order of the processes are replaced to facilitate the parallel working with another process, whereby the construction period is shortened. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
