【摘要】：为了提高城区物流配送中心选址效率,克服传统方法须依靠人工计算的弊端,提出利用在线地图获取路径距离信息的方法。基于配送中心的实际建设和运营情况,确定配送中心选址问题的成本影响因素,设计选址优化系统框架,构建以总成本最小化的数学模型,采用基于整数编码的遗传算法对其进行求解。利用C#语言实现系统架构,并进行计算测试。测试发现:所构建系统能够自动获取城区各节点距离信息,较之传统手段减少了规划人员的工作量,围绕2类算例实施优化选址,均在较短时间内获得了切实可行的选址方案。结果表明,所提出的系统架构具有有效性和适用性,能够有效帮助规划人员实施物流节点选择。
[Abstract]:In order to improve the efficiency of location selection of urban logistics distribution centers and overcome the disadvantages of traditional methods which rely on manual calculation, a method of obtaining path distance information by using on-line maps is proposed. Based on the actual construction and operation of distribution center, this paper determines the cost influencing factors of distribution center location problem, designs the optimization system framework of location selection, and constructs a mathematical model to minimize the total cost. Genetic algorithm based on integer coding is used to solve the problem. C # language is used to realize the architecture of the system, and the calculation and test are carried out. The test results show that the system can automatically obtain the distance information of each node in the urban area, which reduces the workload of planners compared with the traditional methods. The optimal location selection is carried out around two types of examples, and a feasible location selection scheme is obtained in a relatively short period of time. The results show that the proposed system architecture is effective and applicable and can effectively help planners to implement logistics node selection.
