The Extraction of Expert Weights from Pair Wise Comparisons in Delphi Method

Abstract

In the second step of Delphi, it has often seen that experts play their roles with same weights of importance. Meanwhile, some experts clearly wiser and more powerful in such matters than others. There is no specific guidance to find the weight of importance of experts in Delphi process. Therefore, this paper intends to introduce a simple method (based on Eigenvector method - by using the number of iteration to reach convergence) to find the weight of importance of experts in Delphi process. The findings in this paper confirm the effectiveness of proposed method. So that, inconsistent experts get less weight and vice-versa. A numerical example demonstrates the application of the proposed method.
