| description | The aim of this study is to establish a divergence measure integrated with the Technique
for Order of Preference by Similarity to Ideal Solution (TOPSIS) approach for
crisp evaluation that can overcome limitation of previous divergence measures, as well
as to describe its properties. The proposed divergence measure has been enhanced by
utilising fuzzy α-cut, in which experts can identify a wide range of rankings when
their levels of confidence vary since uncertainty or ambiguity is an essential feature of
multi-criteria decision-making (MCDM) cases. This study also provides a modified
technique, the fuzzy MEthod based on the Removal Effects of Criteria (MEREC), by
modifying the normalisation technique and enhancing the logarithm function used to
assess the entire performance of alternatives in the weighting process. The comparative
analyses are conducted through the case studies of staff performance appraisal at
Universiti Putra Malaysia (UPM) and Universiti Malaysia Perlis (UniMAP) that
consist of 6 and 13 sub-criteria, respectively. The simulation-based study is used to
validate the effectiveness and stability of the proposed method. Regarding correlation
coefficients and central processing unit (CPU) time, the findings of this study were
compared to those of other MCDM methodologies. Based on the results, the proposed
technique performed in a manner consistent with the current distance measure
approaches since all of the values of the correlation coefficient were greater than 0.8.
Besides, the proposed technique provides the advantage of being able to assess all
potential score values of alternatives, including 0 and 1. Furthermore, the simulationbased
study demonstrates that even in the presence of outliers in the collection of alternatives,
fuzzy MEREC is able to offer consistent weights for the criterion. Since the
criteria weights significantly affect the results of rankings, the sensitivity analysis is
used to reveal how the rankings change due to the variation of criteria weights, which
mainly explores the influence of single criterion weight changes. The correlation coefficient
values between the original rankings and the rankings with decreasing and
increasing criteria weights are presented. Based on the analysis, the most affecting
criterion to the ranking of staff performance in each category has been identified. In
addition, it has been identified that the proposed technique has the shortest CPU time
when compared to the other divergence measurement methodologies. As a result, the
proposed technique provides more sensible and practicable results than the others in
its category. |
