摘　　要：在固定建设成本风险共担选址-库存问题(Location model of risk pooling,LMRP)研究基础上,本文从优化角度将配送中心建设成本设为配送中心规模的线性函数,将模型扩展为可变建设成本风险共担选址—库存问题(Location model of risk pooling based on variable construction cost,LMRPVCC),构建非线性0-1整数规划模型。采用启发式粒子群算法求解模型,对经典文献算例进行测算,并依据计算结果,对影响模型目标值的相关参数进行敏感性分析。Based on variable cost of construction,we construct a new location problem of risking pool incorporating variable DC Construction,transportation cost,working inventory and safety stock inventory costs at the distribution centers.We formulate this problem as a square nonlinear 0-1 integer-programming model which is to determine which retailer should serve as distribution centers and how to allocate the other retailers to the distribution centers.Applying the particle swarm optimization and several computational instances,we find the suboptimum solution of the model.
