Optimization model and combined simulated annealing algorithm for multi-level multi-commodity logistics network design
多级多商品流物流网络设计的优化模型与组合模拟退火算法*

This paper presented an optimization model for the generic multi-level multi-commodity logistics network design problem with capacity constraint, in which the objective function was to minimize the total cost, including the location cost and transportation cost and inventory cost. The combined simulated annealing algorithm was developed for the model. Practical application denotes the optimization method operates rapidly and the result is rational, so it can provide a scientific decision-ma-king support method for the design of the network. Moreover, the unit inventory cost and unit transportation cost can affect the total system cost, but the transportation cost has more influence on the total cost.
