基于时间可靠性的城市物流配送系统优化策略

配送时间可靠性已经成为城市物流配送系统效率的关键影响因素。为了科学评价物流配送系统时间可靠性,在解析物流配送时间可靠性内涵特征的基础上,揭示了道路交通状态、配送时间窗、配送路径、城市物流配送需求的空间差异是决定城市物流配送时间可靠性的关键因素,并从物流配送路段、物流配送路径、物流配送网络3个层次建立了城市物流配送系统时间可靠性评估模型。最后,以配送时间可靠性最大化为目标提出了城市物流系统配送时间可靠性优化模型,并提出了城市物流配送优化对策,可为改善目前的城市物流配送时间可靠性提供借鉴。 

Optimization Strategy of City Logistics Distribution System Based on Time Reliability

Distribution time reliability has become a significant factor affecting urban logistics distribution system ef-ficiency .To scientifically evaluate the distribution time reliability ,based on summarizing and defining the connotation of city logistics distribution time reliability ,the impact factors of distribution time reliability have been revealed by road traf-fic situation ,distribution time windows ,distribution routing and spatial difference of distribution demand .Then ,the e-valuation model of distribution time reliability has been established based on logistics distribution section ,routing and net-work .On this basis ,an optimization model has been established ,whose aim is to maximize the logistics distribution time reliability .Finally ,the optimization strategies have been proposed from arranging distribution time ,choosing distribution route ,optimizing time window and improving logistics information .
