The Research In The Comphrehensive Evaluation Technology Of Business Administration Based On The Information Theory

It mainly presents some several indexes comprehensive evaluating technologies used in management of enterprise .With beginning of introducing those impotant and often used methods as a whole,this paper studies the fuzzy comphrehensive evaluation in detail so as to make readers hold them more.When discussing how to derive the weight vector of evaluating factors,it gives a new method which makes the weight vector more objective,exact and reliable.And the modle of fuzzy comphrehensive evaluating can be self-adatpble with this kind of weight vector.This method bases on the method of general fuzzy character synthesizing and reasoning,with the principle of Shannon Entropy and intro-entropy. If a factor can be taken on similar fuzzy conditions in every similar type of the principal set, while on different fuzzy conditions in different types of the principal set, this shows the condition of the factor taken on much useful decisively for the system's output. Contrarily, if every possibly conditions of the factor distribute among every type with a most similar frequency, this shows the factor for the results of reasoning without much effective. With munch effective, the factor should be predominant factor we looking for. And its intro-entropy for the system should also bigger. This method is different from tradition method of building index system in: those tradition methods only compute the relation among indexes while mine compute the relation of every factor to ouput.At the end of this paper,it proves this method effective by a practical example,its conclusion can be testified trule on economics and suitable to the fact.
