Manufacturing industry includes multiple business organizations having different decision criterion such as factories, salespersons and customers. It is important to maximize the overall profit while considering the objectives of each organization by appropriate adjustment. We previously proposed the order planning method using indicators of “credibility” that is defined by tardiness. On the other hand, adjusting order quantity is also necessary to decrease tardiness. In this study, the order planning method with considering credibility and order quantity is extended. Several computer experiments are conducted so as to evaluate the effectiveness of the proposed approach.
