Abstract: For the service cost and logistics service quality, the bi-level programming model is designed to select functional logistics provider, the upper-level objective function determines service cost which should be minimized; the lower-level objective function is supplier’s service quality which should be maximized. Through the method of QFD, comprehensive evaluating logistics suppliers by the evaluation index and customer needs, the synthetically expressive degree of each subcontract supplier is gained. The bi-level iterative algorithm is designed for the model, and through a case study, both the model and the algorithm are validated.

摘要： 从物流服务成本和物流服务质量两个方面构建物流服务供应商选择的双层规划模型，上层规划以物流服务成本最小为目标，下层以选择的供应商的综合表现度最大为目标。通过改进QFD模型，将评价指标和客户需求相结合，对待选物流供应商进行综合评价，计算供应商的综合表现度。结合模型的特点设计分层迭代算法，算例验证了模型和算法的有效性。
