地下配送中心功能区布局方法研究

地下配送中心功能区布局是城市地下配送中心规划的一个重要组成部分,直接关系到地下配送中心的建设与发展,对城市地下物流系统的运营也有重大影响。为了避免由于地下配送中心功能区布局不合理而引起的地下物流服务失效,本文提出了基于AutoMod仿真平台的地下配送中心功能区系统布局规划方法。本文首先分析了地下配送中心相关物流运作特性,以功能区间的相关性和搬运成本两个指标建立了功能区布局的多目标0-1整数混合规划数学模型,对指标进行了量化,利用LINGO软件对数学模型进行求解,进而对求解布局方案进行Automod仿真检验和优化,得到最终布局方案。最后,给出了算例说明本方法的可行性。该方法可以有效地分析地下配送中心功能区布局效果,对于建设地下配送中心的决策是十分重要的。

Function Area Layout Method for Underground Distribution Center

Function area layout of Underground Distribution Center (UDC) is an important part of urban underground distribution center planning, it would indirectly affect the construction and development of UDC and even the whole urban underground logistics system. Based on AutoMod simulation platform, the function area layout planning method of UDC was built in order to avoid the UDC operation invalidation because of the illogical function area layout. First, by analyzing relative operation characters of UDC, multi-objective 0-1 mixed integer programming model of function area layout was built based on two indexes as dependancy and transit cost among function areas. Then LINGO software was used to solve the mathematical model and find out the layout scheme after quantifying the indicators. Finally, the final layout was gained by simulation and optimization of AutoMod simulation platform. An example was given to prove the feasibility of the method. The results showed that the method was available to analyze the function area layout impact and it was very important for decision-making of building UDC.
