摘　　要：随着城市交通拥堵问题的日益突出,在物流需求质量要求越来越高的背景下,物流配送的准时性成为物流业发展的一个十分重要的问题。在道路网络畅通可靠度理论的基础上,进行基于畅通可靠度的城市物流配送运输网络优化研究。提出了物流配送运输网络畅通可靠度的概念,建立了物流配送运输网络优化模型,给出了蚁群算法的求解过程,最后进行了案例比较分析,验证了所建模型的实用性。提出的物流配送网络优化模型对指导城市物流配送运输网络优化决策,降低城市物流配送过程中的不确定性具有较好的实用意义。As the problem of urban traffic congestion becomes more and more prominent and quality requirements of logistics demand is growing,it is a very important issue for the logistics industry whether logistics and distribution is punctual.But the time is still the most important.In the condition of traffic congestion,delivery on time has become an increasingly tough business challenges.In this paper,on the basis of unblocked reliability theory of the road network,the authors analyzes the unblocked reliability of transportation logistics and distribution network,puts forward the concept of transportation logistics and distribution network,sets up the model of optimization of transportation logistics and distribution network and solves the model through the ant colony algorithm.Therefore,optimal strategy is providing to direct optimization decision on transportation logistics and distribution network and reduce the uncertainty in the logistics and distribution.
