The Application of the Evaluation Model of Innovation Ability of Zone Logistics System Basing on the NN of Analysis of Principle Divisor of Grey Relationship

The factors that influence on the improvement of the innovation ability in an area are extensive. In order to separate the facilitated function of the logistics from a lot of factors, this paper adopts the analysis method of grey-relationship principle divisor to screen out the evaluation target of the innovation ability of logistics, and establishes the evaluation model of NN of the innovation ability of zone logistics, also according to the NN having the unique functions on the aspects of dealing with the vague, random, large-amount, low-precision information, and so on, and in order to prove its practicability, this paper uses this model to evaluate the innovation ability of the logistics in northeast area. The research indicates that this method debases efficiently the complex degree of network caused by multiple target evaluation, advances the performance of network, which doesn´t only evaluate the discretion of innovation ability in different areas, but also can find the reason that causes the differences, through the comparison of each divisor. Besides, comparing with the arithmetic of BP of principle divisor, the evaluation model of NN basing on the analysis of grey-relationship principle divisor can make the evaluation goal more definite, which improves the precision of input data of network, so that it reduces the error more effectively
