Human resource management is one of important affairs of national defense management. Furthermore, the operational tasks of military officer's evaluation are the core of personnel management that divided into two parts of compulsory distribution and three-level evaluation process based on some sort of evaluation credits. The index of performance evaluation contains some countable mathematical index; however, some problems about qualitative evaluation are inevitable in the process of evaluation. There are some reasons, for example, subjective judgement and preference from superior officer and the difference among individual's cognition. This research expects to Fuzzy multi-criteria decision making method, adapted to geometric mean method to get the fuzzy rating of sub-criteria, furtherrmore, using fuzzy group decision making method to get the fuzzy rating of criteria, for aggregating the operation to rank aggreated fuzzy numbers. For practical application, this research investigates military official performance evaluation for four officers, Finally , we propose the Fuzzy multi-criteria decision making method which can be applied by decision makers in military official performance evaluation
