A Proposed Production Decision Method for Order Planning Considering Decision Criteria of Multiple Organizations

Abstract Organizations in manufacturing industries, such as factories, salespersons and customers, have respective decision criteria to determine order quantities and production schedules in order planning. In our group, a production decision method that adjusts order quantities and decides the production schedule to maximize the overall profit of an organization in consideration of the customers’ credibility has been proposed. In this paper, the proposed method introduces the order aggregation period for arranging the customers’ inquiries to determine the order quantity and production schedule while reducing the tardiness of product delivery. A computational experiment is performed to evaluate and discuss the effectiveness of the proposed method.
