Abstract:

Considering the substitutability and complementarity of products, this paper constructs two decentralized decision-making models and a centralized decision-making model of a multi-agent e-supply chain and studies the optimal decisions of each model. Then, aiming at products that are different in terms of substitutability and complementary, this paper compares the optimal decisions of each model and respectively designs a coordination mechanism based on commission distribution for each model. The research indicates that: (1) The service-level of network platform and the profit of e-supply chain are the highest in centralized decision-making model no matter whether the products are substitutable or complementary. However, the dominant enterprises can increase their own profits in decentralized decision-making models. (2) As to the substitute (complementary) products, the service-level of platform increases (decreases) with the growth of the degree of products’ substitutability (complementarity), but the sales price, manufacturer’s profit and platform’s profits decrease (increase) with the growth of the degree of products’ substitutability (complementarity). (3) The sales price of substitute (complementary) products reaches the highest in centralized decision-making model. Therefore, these conclusions can enrich and improve the theoretical basis of e-supply chain.

Key words: e-supply chain, coordination, substitutability and complementary of products, multi-agent
