PURPOSE:To evade excessive track-back even if the number of devices increases, and to realize the assignment of a part within limited time in a state that constraint is fulfilled in the re-assignment of the part at the time when the constraint of the device is not fulfilled. CONSTITUTION:This method consists of a process in which it is checked whether the constraint is fulfilled all over the device or not during a period from time when the constraint of the device is fulfilled to the time of the start of a new assignment of the part (step 1), a process in which if the constraint is not fulfilled, the part is divided after the time when that constraint comes not to be fulfilled, and the part is re-assigned, and it is checked whether the constraint is fulfilled in the whole device or not extending over the period from the time when the constraint becomes not to be fulfilled to the starting time of the new assignment of the part (step 2), and a process in which the new assignment part is assigned by a part managing part after the former check (step 3). |
