Abstract: To research the supplier's pricing decision in a two-echelon supply chain consisted of a risk-neutral supplier and multiple risk-preferences competing retailers,the two periods profit models for each member with computational experiments were established and analyzed,with consider of retailers' misplacement and shrinkage errors.The supplier could adjust wholesale price and buy-back price,while the retailers could adjust the order quantities.The results showed that the average profits of strong risk-preferences retailers were higher than that of the weak risk-preferences retailers.The supply chain would be creaked when supplier only adjusted the wholesale price;the supply chain partners' profits would be fluctuated greatly when supplier adjusted both the wholesale price and buy-back price.Meanwhile,the supplier obtained the maximum average profit while the retailers obtained minimum average profits and order quantities.

Key words: two-echelon supply chain, competing retailers, risk-preferences, computational experiments, pricing decision
