Research on TOPSIS integrated evaluation and decision method based on entropy coefficient

Abstract

A new approach to the complex problem of the rationality in evaluating information system integration is proposed to avoid non-determinacy and optional judgements resulted from subjective opinions. To ameliorate the inefficiency of means to decide proportion coefficient in the course of the evaluation of information system integration, subjective opinions are combined with objective situations and the quantitative analyses are combined with qualitative analyses. The weight coefficient is given by means of entropy coefficient and TOPSIS method for the first time. The proposed method is applied to evaluating information system integration solutions and satisfactory results are abtained.
