摘　　要：【目的/意义】集成优化生鲜运输路径、自提点选择及末端客户分配等多个决策的生鲜物流网络,可提高物流系统综合效益。【设计/方法】针对设施繁忙率影响自提效率,构建设施繁忙率测度函数;针对客户对高服务水平的要求,构建自提点服务水平函数;进而建立寻求总成本最小、自提效率最大和服务水平最高的生鲜自提点选址及路径优化模型,并设计了基于“一阶段编码”方案和新的客户分配策略的多目标禁忌搜索算法对模型进行求解,最后通过算例验证模型和算法的有效性。【结论/发现】考虑自提点服务水平和设施繁忙率,能够在满足末端客户多种需求的同时,提高自提点设施效率;总成本、设施繁忙率和自提点服务水平之间相互影响,决策者应根据企业实际运营情况进行合理决策。[Purpose/Significance]The logistics network for fresh products integrating the optimization of transportation routes,self-collection selection and allocation of customers can improve the comprehensive benefits of logistics system.[Design/Methodology]The busy facilities measure function is set up to improve the selfcollection efficiency.Then the location and routing optimization model of pick-up points is constructed to minimize costs and maximize the efficiency of pick-up points and service level.The self-collection service level function is established to meet customer requirements on high service level.In addition,this paper explores the self-collection location of fresh products and routing optimization model that have the minimum total cost,maximum self-collection efficiency and highest service level.The multi-objective tabu search algorithm based on the“one-stage coding”scheme and novel customer allocation strategy is designed and the feasibility and effectiveness of the model and algorithm are verified by calculation examples.[Findings/Conclusions]The results show that given the service level and busy facilities of self-collection,the efficiency of self-collection facilities can be improved while satisfying diverse customer requirements.As the total cost,busy facilities and self-collection service level affect each other,deciders should make reasonable decisions based on the actual business operations.
