A fuzzy-based military officer performance appraisal system

In this paper, we developed a computer-based group decision support system—fuzzy group decision support system (FGDSS), which include three ranking methods (intuition ranking, Lee and Li's fuzzy mean/spread and metric distance) to provide more transparent information and help manager to make better decision under fuzzy circumstance. First, we derive metric distance to rank fuzzy numbers, and we execute some simulation experiments to validate the proposed method. A practical numerical example is introduced to illustrate those three methods and compared with different alternatives by FGDSS.
