The Research On Distribution Center Location And Distribution Path Optimization Of Commercial Concrete

In recent years, commercial concrete, as an important building material, is widely used in infrastructure construction of our country such as buildings, roads, gardens, water conservancy and others, and its production has always keeps growing in a rapid pace. But the rate of commercial concrete utilization is still at a low level. The main reason lies in the easy access of commercial concrete industry, the irrational distribution pattern of a large quantity of concrete mixing stations, and the vicious competition among the commercial concrete enterprises which lead to the waste of resources.Through the analysis of the concept, characteristics, basic process and the current situation of commercial concrete distribution, some suggestions are put forward for a better development in the paper.And the location of commercial concrete distribution center and the commercial concrete distribution path are optimized, aiming at enhancing the competitiveness of commercial concrete distribution enterprises, and promoting the development of commercial concrete industry.As to the location of commercial concrete distribution center, qualitative and quantitative analyses are used together in this paper. Firstly, by means of literature research and questionnaires, evaluation index system of commercial concrete distribution center is established and each influencing factor is determined. Then the method of fuzzy comprehensive evaluation is used to select the location of the distribution center according to the results of questionnaires. Secondly, based on the theory of set covering model, two stage models which combine the set covering model and the maximum coverage model are established to achieve the maximum coverage requirement of commercial concrete distribution.As to the optimization of commercial concrete distribution path, distribution of the shortest path and order allocation are focused in this paper. In the optimization process of the shortest path, the real-time condition of the road is considered, and road traffic indices are introduced to modify the node distance. And the Dijkstra algorithm is used to solve the problem of choosing distribution path of different periods. In the aspect of order allocation optimization, concrete order distribution model is established to achieve the optimization of the order distribution and reduce the total cost of distribution which verified by a case.In this paper, the method of combining qualitative and quantitative analysis is used in the process of distribution center location, the shortest path choosing is achieved by considering the real-time road condition, and the order allocation optimization model is established, which provide theoretical basis and practical guidance for the distribution center location and path optimization of commercial concrete.
