【摘要】：伴随着我国对铁路基础设施投资力度的不断加大,铁路现有里程数已突破两万余公里,对已建铁轨的维护保养日益成为铁路运营管理机构重要的日常工作,铁路养路机械用具的需求将呈刚性增长态势,由此带动作为铁路养路机械用具最主要供应商之一的四通机械产品需求量的不断加大。但是,就目前国内铁路养路机械产品制造商所需关键零部件——E级轴承的供应情况来看,存在着供货渠道混乱不规范、短期逐利行为大量存在等不良现象,严重影响了供应链中上下游企业之间稳定、长期合作关系的建立。这不仅制约了四通机械生产经营规模的进一步扩大,而且造成产品生产成本的大幅上涨,例如运输成本和订货成本。因此,应用包括物流配送中心选址的变量——中心解析法、(1,L)随机储存策略模型、基于容量限制的设施选址问题模型、层次分析数学模型等先进的物流配送理论与技术,实行“统购统配”的新模式以降低包括运输成本在内的生产成本,保证四通机械下属各子公司对于E级轴承的需求已迫在眉睫。本文围绕如何应用上述先进物流配送理论与技术来构建“统购统配”的新模式以达到降低成本、保证供应这一中心问题展开的,并通过理论与实践的探讨,指出建立四通机械自有E级轴承物流配送中心是解决上述中心问题的最有效途径。本文首先广泛搜集真实可靠的企业数据,根据需求量——中心解析法(结合(1,L)随机储存策略模型)、距离值——中心解法、基于容量限制的设施选址问题模型,在四通机械现有生产经营布局的基础上,对物流配送中心的选址进行了定量计算分析,初步得出可供选择的若干备选地址；其次,通过层次分析数学模型(即AHP方法)的应用,在充分考虑了四通机械实际生产经营状况的条件下,依据建立起的评定标准来比较上述得出的各个备选地址的优劣,从而得出最佳备选地址；最后,本文分析了文中探讨的方案可能存在的不足之处,并相应提出了改进建议。
[Abstract]:With the increasing investment in railway infrastructure in our country, the existing mileage of railway has exceeded more than 20,000 kilometers. The maintenance and maintenance of the railway track has become an important daily work of the railway operation and management organization. The demand for railway road maintenance machinery and appliances will show a rigid growth trend, which will lead to the increasing demand of four-way machinery products as one of the most important suppliers of railway road maintenance machinery and appliances. However, from the point of view of the supply situation of E-class bearings, which are the key parts needed by domestic railway maintenance machinery manufacturers, there are some undesirable phenomena such as the confusion of supply channels and the large number of short-term profit-driven behaviors. It seriously affects the establishment of long-term cooperative relationship between upstream and downstream enterprises in supply chain. This not only restricts the further expansion of the production and operation scale of the four-way machinery, but also results in a sharp increase in the production cost of the products, such as transportation cost and order cost. Therefore, advanced logistics distribution theory and technology are applied, such as variable center analysis method, (1L) random storage strategy model, facility location problem model based on capacity limitation, analytic hierarchy process mathematical model, and so on. In order to reduce the production cost including transportation cost, it is urgent to implement the new mode of "unified purchase and distribution" to ensure the demand of E class bearings for the subsidiaries of the four-way machinery. This paper focuses on how to apply the advanced logistics distribution theory and technology to construct a new mode of "unified purchase and distribution" in order to reduce the cost and ensure the supply. It is pointed out that the most effective way to solve the above problems is to set up the logistics distribution center of four-way machinery's class E bearing. In this paper, the real and reliable enterprise data are collected widely, according to the demand-center analytical method (combined with (1L) random storage strategy model), the distance value -center solution, the facility location problem model based on the capacity limitation. On the basis of the existing production and management layout of the four-way machinery, the location of the logistics distribution center is calculated and analyzed quantitatively, and some optional addresses are preliminarily obtained. Secondly, the application of AHP (AHP method) is introduced. Under the condition that the actual production and operation of the four-way machinery are fully considered, the advantages and disadvantages of the above mentioned alternative addresses are compared according to the established evaluation criteria, and the best alternative addresses are obtained; finally, This paper analyzes the possible shortcomings of the scheme discussed in this paper, and puts forward corresponding suggestions for improvement.
