多级冷链物流网络优化研究

Study on Optimization of Multi-echelon Cold Chain Logistics Network

针对生鲜农产品在冷链物流过程中的不合理运作而产生不必要浪费的普遍问题,对冷链物流网络进行上下节点指派关系的优化。以湖北省为例,结合惩罚函数,以成本最小化为目标构建备选配送中心选址模型,确定7个备选配送中心地址,利用遗传算法,采用MATLAB进行编程实现备选地址的确定和各节点之间的指派。研究中心优化的重点在于成本,避免了冷链运输存储过程中的浪费,有一定的实践借鉴价值。

In this paper, in view of the universality of the excessive waste due to the unreasonable operation of the fresh farm produce cold chain activities, we proceeded to optimize the assignment relationship between the upper and lower nodes of the cold chain logistics network. With Hubei as example, in connection with the penalty function, we formulated the alternative distribution center location model aiming at cost minimization, used it to determine seven locations from which to choose from, and at the end, based on the genetic algorithm, finalized the location of the distribution center as well as the assignment relationship between the nodes.
