摘要
介绍了冷链物流的定义及我国农产品冷链物流存在的问题,根据冷链物流配送的特点,探索冷链物流配送路径的优化方法.在建立农产品冷链物流配送路径优化模型的基础上,构造了求解该优化问题的粒子群优化算法,并以实例进行计算.结果证明该算法对于农产品冷链物流配送路径优化问题可以有效的求出最优解,是解决路径优化问题的一种好方法.
The definition of the cold chain logistics and the problem of the agricultural cold chain logistics are introduced. According to the characteristics of cold chain logistics, explo- ring the cold chain logistics distribution path optimization method. Based on the model of the agricultural products cold chain logistics distribution routing optimization, particle swarm optimization algorithm is constructed to solve the optimization problem. Taking an example, the results have been conducted finally to demonstrate the effectiveness of the algorithm for agricultural products cold chain logistics distribution routing optimization problem.
