Relative Effectiveness Analysis under Fuzziness

Effectiveness is an important criterion of performance evaluation that requires the extent to which the goals are achieved. Finding a value for this criterion becomes difficult, when it is considered in the context of fuzzy goals. However, we often require it numerically in a scale to monitor the performance level in a meaningful way. But, there exists no such structured methodology in the literature to compute effectiveness value in a fuzzy environment. This paper defines a fuzzy effectiveness measurement model in a multi-criteria framework to assess this value in the range of 0 to 1. A fuzzy goal programming approach is used to determine the effective point, which also acts as the benchmark for the proposed relative effectiveness analysis. Finally, this approach is demonstrated for its applicability, taking an example of performance evaluation of candidates in a semester examination. The result is then compared with the existing procedure of cumulative- grade- point average.
