摘要
我国物流产业平均成本高,综合利润率低,长此以往不利于物流产业与互联网消费市场的发展。根据集货行为实现物流业降本增效这一基本理论,提出物流始端集中化经营策略,探寻符合我国实际情况的高效低成本的快运物流运营模式。首先,以物流与用户接触的网点为出发点,建立降低成本与增加利润的双层规划模型。其次,对物流商与用户是否选择此模型所构造策略进行博弈分析。最后,对快递网点数据进行实证分析,采用极点搜索法求解策略模型的最优解,并依据最短路径问题的解决进一步改进集中化策略实施的时间约束。研究发现,理论和实证结果均表明物流始端网点的集中化策略可以达到高效低成本的优化目标,极点搜索法和策略博弈可以有效解决物流优化中的双层规划模型问题。
The high average cost and the low overall profit margin of China’s logistics industry are not conducive to the sustainable development of the industry and online consumer market.This paper proposes a primary centralized logistics operation based on freight consolidation to cut costs and improve efficiency in the logistics industry.It explores the efficient and low-cost operation mode of express transportation logistics,conforming to China’s actual conditions.First,this paper takes logistics and customer contact outlets as the starting point to build a bi-level programming model to cut costs and increase profits.Then,the game analysis is made on whether the logistics providers and users choose the strategy built by this model.Finally,the data of express outlets are empirically analyzed by seeking the the optimal solution of the strategy model through the peak searching algorithm.The time constraint in the implementation of the centralized strategy is further improved according to the solution of the shortest path problem.Our theoretical and empirical results show the centralization strategy of logistics outlets improves efficiency and reduces costs.The peak searching algorithm and strategy game effectively address the problems of the bi-level programming model in logistics optimization.
