Cooperative Scheduling of Distributed Manufacturing with Mixed Transportation Problems

Abstract

Since each company has to concentrate on core competence in the supply chain, production is never completed inside of the company. This paper proposes a cooperative scheduling technique using lagrangian decomposition coordination method. The target problem is a production model including suppliers, transportation service vendors, and makers of the products. The transportation routes can be mixed due to the cost reduction. This paper shows a mathematical model of cooperative scheduling and some results of numerical experiments.
