Abstract: It is vital to construct the Direct Influence Matrix（DIM） in DEMATEL procedures. There are some disadvantages for the construction of DIM. Not only the experts’ judgment is arbitrary, but also the integrated mechanism of expert opinion is unclear. To overcome the above drawbacks, an improved group DEMATEL decision approach based on intui-tionistic fuzzy preference is presented. In the perspective of system intuitive thinking the new method fully considers the expert’s cognitive ability, personal preferences, situational characteristics, and it reflects expert’s judgment result by intui-
tionistic fuzzy numbers. On the one hand the new approved method improves the existing evaluation model and makes the expert’s judgment on complex problems more scientifically, on the other hand the integrated manner of experts’ intuitionistic fuzzy information by AWD may reveal the integration mechanism of group decision. By a numerical case, the approach is validated to be scientific and it can be well applied to solve the real issues.
