Abstract: In a three-echelon non-instantaneous deteriorating items supply chain composed of manufacturer-transporter-distributor,the market demand was influenced by the selling price and deterioration time of the products,and the transportation cost was shared by manufacturers and distributors.The pricing strategy and the expected income level of each member enterprise under three decision-making modes of no cooperation,partial cooperation and overall cooperation were examined respectively.The results showed that the sales price of non-instantaneous deteriorating items was decreased with the deepening of cooperation among member enterprises,and the quantity of market supply and expected income of supply chain system were increased.Considering the market efficiency and the expected income of supply chain system,the overall cooperation among the member enterprises was the best decision-making mode.A coordination mechanism of expected income distribution was designed for the overall cooperative decision-making mode,and its effectiveness was demonstrated.Example analysis demonstrated the process of supply chain pricing and coordination,and the effect of characteristic parameters on sales price,order quantity and expected income was obtained with sensitivity analysis.
