Abstract :
The Consistency is the most important measurement of the results from pairwise comparison in the AHP. Pairwise comparison is a method to calculate the weights for each element in order to perform a comparison of two advantages. The consistency of the AHP will be determined by the value of C.I. from the pairwise comparison table. If its value is for the case exceeding 0.1 (Saaty´s criteria 1980) [12] is not consistent, pairwise comparison has to perform again. A longstanding weakness of AHP is explored by considering combinations of research costs, which seeks to address a difficult problem. This article aims to develop an efficient method to decrease the value of C.I. using an evolutionary algorithm and random search approach. Finally, we propose a software solution and discuss its effectiveness.
