ABSTRACT
FAHP is a commonly used method in analyzing multi-factor evaluation or multi-attribute decision-making problems. However, FAHP has some serious logistic mistakes. Since it cannot maintain the independence of alternatives, FAHP cannot lead to an ordering of alternatives that is consistent with their ordering before the values of the assessments or the quantity of alternatives change. This study looks into the cause of rank reversal phenomenon and finds that rank reversal is caused by change of local priorities before and after an alternative is added or deleted. Therefore, using a numerical illustration, the mistake of traditional FAHP is found out. An improvement on FAHP which can keep the consistency of the alternatives ordering results is put forward in this study.
