Modeling and complexity study of output game among multiple oligopolistic manufacturers in the supply chain system

摘要

Supply chain system is a complex system in which node enterprises play important roles and exert great influence. This paper proposes an output game model among multiple oligopolistic manufacturers under the circumstances of information asymmetry and analyzes the Nash equilibrium in the model. The manufacturers usually base their production decision making on the volume of order from distributors and the production decisions made by other manufacturers. They also suitably adjust the output. If the adjustment speed accelerates, chaos will be caused in the manufacturers' production decision. This paper analyzes the proposed model from a perspective of complex dynamics and discusses the impact of system parameter on the complexity of this discrete chaotic system. The measures to retain chaos among manufacturers are suggested.
