    Despite the importance of multicriteria decision-making (MCDM) techniques for constructing effective decision models, there are many criticisms due to the occurrence of a problem called rank reversal. Nevertheless, there is a lack of a systematic literature review on this important subject which involves different methods. This study reviews the pertinent literature on rank reversal, based on 130 related articles published from 1980 to 2015 in international journals, which were gathered and analyzed according to the following perspectives: multicriteria technique, year and journal in which the papers were published, co-authorship network, rank reversal types, and research goal. Thus our survey provides recommendations for future research, besides useful information and knowledge regarding rank reversal in the MCDM field

    EFFECTIVENESS ANALYSIS OF DERIVING PRIORITY VECTORS FROM RECIPROCAL PAIRWISE COMPARISON MATRICES

    Pairwise comparison is commonly used to estimate the priority values of finite alternatives with respect to a given criterion. We evaluate seven specially selected direct methods of estimating priority vectors from reciprocal pairwise comparison matrices under four effectiveness measures. A simulation experiment is designed starting with true priority vectors that represent difficult cases of "no obvious best alternative" and "two equal best alternatives". The simulation results suggest that the geometric mean method is in general the best method with the normalized column mean method as a close second best.Decision analysis, pairwise comparison, priority values, ratio scale
