On the basis of the analysis on the theories and methods on relative entropy and with the union of extension transformation and entropy optimization, this paper establishes the reliability and sensitivity analysis model of extension group decision-making centered on optimizing decision-making. With the implementation of the reliability analysis of extension group decision-making and the categories and judgment of influential factors by relative entropy , it lends optimal substantial weight to the sensitivity analysis, through which it would further observe the main content, changing scope and affective extend of group decision-making influential factors and furnish the reliability analysis with addition and intense. Combined by qualitative analysis and quantitative study, it realizes the comparison and selection for objects in uncertain environment, which leads to the promotion on the accuracy and the reliability of multi-factors analysis and multi-projects evaluation in extension group decision-making.
