Analysis of Coopetition Mechanism in Heterogeneous Supply Chain Alliance Based on Lotka-Volterra Model

The heterogeneous enterprises which provide manufacturing and producer services form a supply chain alliance for the sake of profit maximization, where there are both competition and cooperation interactions between them. In this paper, Lotka-Volterra model is used to depict supply chain alliance coopetition mechanism among heterogeneous node enterprises and the stability of alliance is analyzed. Results show that excessive competition can lead to inefficiency. Then the dynamic coopetition mechanism is studied to increase the efficiency of supply chain alliance in macroscopic point of view, the evolvement and stability of the alliance depend on both of its natural growth rate and coopetition effects, the cooperation between heterogeneous node enterprises can produce more alliance profit than competition. Dynamic coopetition mechanism can promote the further development of supply chain alliance. Finally, the simulations and two extensions are presented in the end.
