高科技易逝品的三层联合定价与订货决策

研究高科技产业背景下三级供应链系统中原材料供应商的最优定价决策、制造商和零售商的最优定价和订货决策. 围绕高科技易逝品的售价和零部件购买价格随时间递减的特点, 分别建立以零售商和供应商为主导的三层联合定价和订货模型, 并设计了三层粒子群算法对模型进行求解. 数值实验验证了所提出算法的有效性. 对模型特点的分析结果表明, 零售商主导下的三层供应链系统能更好地提高整个供应链的效率.

Tri-level joint pricing and lot-sizing decisions for hi-tech perishable product

Optimal pricing decisions of the raw material supplier, optimal pricing and lot-sizing decisions of the manufacturer and the retailer are considered in the three echelons supply chain system under the background of the hi-industries. Two tri-level joint pricing and lot-sizing models are established, which are respectively guided by the retailer and the supplier by considering the deteriorating manufacturer’s purchase cost and the end-consumer’s market price. A tri-level particle swarm optimization algorithm is designed to solve the problems. An example is employed to illustrate the feasibility of the proposed algorithm. The analysis of features of the models show that the retailer guided supply chain performs better than the system guided by the supplier in improving efficiency of the whole supply chain.
