The paper bases on competency including personality, attitude, knowledge and skill of competency and so on. It adopts qualitative index and quantitative index and assesses the attitude, achievement, ability and potential across-the-aboard. The paper draws on fuzzy synthesis decision, analytic hierarchy process, fuzzy approximation and factors weight design and so on in fuzzy mathematic by dint of the research about management by objective, 360 degree feedback, key process indication and balance score card. We establish performance assessment index based on competency model and distribute different weigh. We can set the weight of different assessment index. At the same time, we must set assessment relation and corresponding weight considering different people. We also assign different weight to every assessment factors according to the require of corporation. Then we can go on assessing more particularly and compressively.

本论文基于能力素质模型，包括能力的人格、态度、知识和技能等要素，采用定性指标和定量指标，对员工的工作态度、业绩、能力和潜力进行全面考核，通过对目标管理、360度反馈评价法、关键绩效指标和平衡记分卡等考核方法的研究，独创引入模糊数学中的综合评定法、层次分析法、模糊贴近度以及要素权重设计等方法，以能力素质特征模型为基础确立绩效考核指标，利用主观经验法、层次分析法等确定各考核指标的权重，同时考虑到企业中不同人员的考核，还需要定出考核关系及其权重，同时还可以根据企业要求为各考核要素分配权重，这样更详细、更全面的进行考核，并借助软件工程，利用UML建模语言把整个软件系统化、模型化，采用。
