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.

Key words: supply chain coordination, supply chain pricing, non-instantaneous deteriorating items, time-varying demand

摘要： 在“制造商—运输服务商—分销商”组成的三级时滞变质品供应链中,市场需求受产品销售价格与变质时间影响,且运输费用由制造商和分销商共同分担,分别考察了各成员企业在无合作、局部合作及全面合作3种决策模式下的产品定价策略与期望收益水平。结果表明:随着各成员企业间相互合作的不断深入,时滞变质品的销售价格降低,市场供给量与供应链系统的期望收益增加。因此,无论是从市场效率还是供应链系统期望收益角度考虑,各成员企业间全面合作都是最佳决策模式。为全面合作决策模式设计了一种期望收益分配的协调机制,并论证了该协调机制的有效性。算例分析演示了供应链定价与协调过程,敏感性分析给出了特性参数对销售价格、订货批量与期望收益的影响。
