【摘要】 以B2C电子商务企业为背景,结合实际的物流配送网络,对原有的有时间窗约束但顾客不能被多次访问的物流配送模型进行优化,建立了有时间窗约束顾客可被多次访问的物流配送模型,通过仿真案例表明多次访问的物流配送模型要比顾客不能多次访问的模型所需的配送费用要少,从而验证了有时间窗顾客可多次访问的物流配送模型更能适应电子商务环境。更多还原

【Abstract】 This article takes the B2C electronic commerce enterprise as a background,combines with the actual logistics network,and optimizes the original model that has time window constraint but can’t be visited many times by customers,then establishes the logistics model that has time window constraint and can be visited many times by customers.Through the simulation case,it indicated that the distribution cost of the model witch can be visited many times is less than that of witch can’t be visited many times.So the model that has time window and can be visited many times is more suitable for the environment of E-Commerce.更多还原
