摘　　要：随着人们对产品品质和食用安全性要求的提高,如何降低易腐物品损失以及提高资源利用率成为一个关键问题。由于易腐物品有显著的时效性,并且部分易腐物品在不同的生命周期阶段有不同用途,根据配送时间和销售商对多用途物品的需求种类以及品质要求,本文研究了多用途易腐物品配送中心选址问题。根据Osvald和Stirn(2008)[15]的假设,建立了一个有容量限制和货物中转的多用途易腐物品配送中心选址模型;并采用拉格朗日算法求解模型,将其结果与精确解比较,取得了较好的效果。最后,将是否考虑易腐物品时效性和多用途性的两种情况进行比较,得出考虑此两种因素将大大降低易腐物品因时效性带来的损失。With the growth of the requirement for the quality and safety of the product,how to decrease the loss of the perishable foods as well as improve resource usage turns a key point.Since perishable items are sensitive to the time,and a part of them have different usages during the whole lifetime,the paper researches the distribution centers location problem in perishable items logistics network according to the transportation time and different needs of the retailers.With the assumption of Osvald and Stirn,A PPMULP model is proposed,which is solved by the lagrange relaxation method.It is found that this algorithm is effective and efficient.Finally,it is concluded that considering perishable items＇ sensitivity to time and its multi-usage can decreases the cost led by deterioration when compared with the situation which does not consider the two factors.
