Improved Delphi method with weighted factor and its application

Abstract

In view of long duration, high costs and expert evaluation value with many extreme points of the Delphi method, using the fuzzy method, this paper proposes an improved Delphi method with weighted factor in order to reduce the influence of subjective factors and shorten the consulting time. Then, it applies the improved Delphi method to simulate in the context of stroke rehabilitation evaluation system. Simulation results show the effectiveness of the proposed method.
