PURPOSE: To reduce the duplex of the judgement of a transition condition, to reduce memory capacity and to improve execution speed by taking over that the condition of transition, which is previously evaluated, and an event are not realized to a next transition condition. CONSTITUTION: Evaluation orders '2', '1' and '3' are mentioned in the respective transition conditions (1), (2) and (3), and the transition condition and the event are mentioned with the evaluation orders. For evaluating the transition conditions (1), (2) and (3) from branching, the transition condition (2) of the evaluation order '1' is executed at first as shown by the evaluation orders '1', '2' and '3', and a content when the transition condition is not realized is taken over to the transition condition after the next transition order. The contents of the transition conditions (1) and (3) after the next evaluation order '2' are partially eliminated by taking over the content when the transition condition which is previously evaluated is not realized. Thus, the evaluation speed of the transition condition is speeded up and the memory capacity can be reduced. |
