Study On The Combination Of TOPSIS Optimization And Grey Correlation Analysis In The Logistics Warehouse Investment Decision-making

With the development of economic and concerning on core competition, out sourcing has been most important part in the enterprise strategy. Then create a new industry——logistics. The modern logistics provide not only the traditional functions but the advanced ones, for example, designing the logistics project for enterprises and so on. In some sense, the development of logistics represents the overall level of development of a country.In recent years,with the economic effect and policy support, our logistics industry turn into a high-speed development stage. With the rapid development of logistics of capital, the expansion of the scale of sharp expansion of logistics warehouse construction become inevitable. As indispensable logistic investment, how to scientifically and effectively in cost saving and improve the efficiency of operations is one extremely important factory must be considering in the warehouse construction. The rational decision of warehouse construction restricts the further development of the modern logistics industry.However, the data of logistics warehouse investment decision-making process is often very limited and due to various objective and the human factors,the data have no typical volatility of distribution. In this case, to establish a scientific and effective decision method is very difficult. This paper tries to research this problem. In a large number of reading domestic and foreign literatures, compared various traditional logistics warehouse investment evaluation methods, from the two aspects of economic and technology, to project the optimal economic efficiency targets, , I construct a new model of logistics warehouse investment evaluation by merging the Grey Correlation Analysis Method and TOPSIS Analysis Method. First, based on the expert advices, the paper uses the Analytic Hierarchy Process (AHP) to determine the key indexes weights, to avoid the problems in traditional evaluation that the key indexes weights only depending on experience or personal preference. Secondly, based on the analysis of characteristics of logistics warehouse investment project, Grey Reational Analysis Method and TOPSIS Analysis Method were studied. Through the dimensionless way, this paper merges two methods into the same evaluation model of comprehensive evaluation system.Finally, the paper uses the second phase of logistics warehouse construction decision project of A base area in Qinzhou in Provinces Guangxi as the example, using the model to evaluate the project.
