Model construction and application of national logistics competitive strength based on neural network

National logistics competitive strength is the sum of logistics service capability that a country reflects in domestic and abroad markets. It can be measured by service capability of logistics infrastructure network. In context of international financial crisis, logistics adjustment and revitalization plan, how to enhance national logistics competitive strength has become an urgent problem that needs to be solved for government macro-management department. To enhance national logistics competitive strength, we need to evaluate and keep abreast of its status. Therefore, the paper defines concept of national logistics competitive strength and builds indicators system for measuring it. In the end, the paper constructs evaluation model which is based on BP neural network, using Matlab software for simulation application. © 2010 ASCE.
