The research of comprehensive evaluation based on the TOPSIS method

Enterprises are the backbones of national economy. Enterprise's performance reflects a nation's economic power. In this paper, we first put forward three principles of establishing the index-system of the comprehensive evaluation of enterprise's informatization level. Then, we determine the corresponding index-system on this foundation. Finally, we introduce TOPSIS method to evaluate the informatization level of different enterprises. The determination of property weight is the key to this kind of multi-property decision-making problem. There are generally two kinds of methods, i.e. the subjective method and the objective method. The subjective method mainly includes: expert investigation method, Delphi method and AHP method; and the objective method mainly includes: entropy weight coefficient method and fuzzy clustering analysis. Since the first three methods have more subjective factors while the last one is mainly used in the important degree classification of fuzzy index. Hence, we use the entropy weight coefficient method to determine the weight of evaluation index.
