中文摘要：

为优化生鲜农产品物流网络布局,以从产地、预冷站、配送中心到各个需求点总物流费用最小为目标函数,并结合生鲜农产品时间敏感特征,通过采集腐烂指数经验数据,测算出因腐烂变质造成的物流损失成本,建立生鲜农产品物流网络布局非线性规划模型,设计相应的遗传算法.算例验证了模型和算法的有效性.

英文摘要：

To optimize logistics network layout for fresh agricultural products,the minimum total cost related to the process,in which goods were delivered from producing area,through pre-cooling station and distribution center to the ultimate customers,was taken as the object function,and time sensitive feature of the fresh agricultural products was considered as well.The logistic damage cost because of decay was calculated through collecting experience data of decay exponential, and a non-linear programming mathematic model for logistics network nodes for fresh agricultural products was put forward,and corresponding genetic algorithm was designed.The example verifies the effectiveness of the proposed model and algorithm.
