Towards an Optimal Order Planning in Global Supply Chain

This paper presents the optimal order planning and parts inventory allocation method which imitates multiple negotiation among various parties with combinatorial auction. Each company which constitutes the supply chain estimates the satisfaction value of each order. Proposal method decides an order planning to aim maximizing an average of each company's satisfaction value. The method mimics that each company negotiates with others by using combinatorial auction. A numerical example is then discussed to demonstrate its suitability in obtaining an optimal order under multiple negotiations with participating companies.
