Thirdly, the development of DEA and the application of three-stage DEA model are studied by the paper.

再次，本文研究了DEA方法的发展进程和三阶段DEA模型的应用特性。

Based on them, this paper proposes evaluation indexof fund performance from the aspect of finance, investor and interiormanagement. Considering the limitation of data envelopment analysis approach usedto evaluate fund performance, such as conventional DEA models can not considerinputs and outputs of evaluation units simultaneously, and an input-oriented DEAmodel and output-oriented DEA model often produce different evaluation results,this paper proposes a general form of DEA model which is input- andoutput-oriented by using multi-objective optimization and fuzzy set theory. Sincethe general form of DEA model can be transformed into a conventional input oroutput oriented DEA model by using special membership functions, it can beseemed as a nature extense of conventional DEA models, and a conventionalmodel can be regarded as a special case of DEA mdoel with general form.

针对现有基金绩效评价方法中较具优越性的数据包络分析方法的不足，如传统DEA模型不能同时综合考虑评价单元的输入和输出，以及分别采用面向输入和面向输出DEA模型评价基金绩效时，常常出现不一致的评价结果等，本文以多目标优化与模糊集合理论为工具，提出了一种能够同时面向输入和输出的DEA一般形式模型，并通过选择一些特殊的模糊集合隶属函数，使得这种DEA一般形式模型成为传统DEA模型的自然推广，而传统DEA模型是该模型的特殊形式。

The traditional DEA model can not beused to deal with such stagewise operation problems. In order to avoid the limitation of the traditional DEA model, a multi-stage DEA model was set up based onthe idea of the DEA model with uncontrollable factor. Simultaneously, considering the shortage of the single DEA model, the multi-stage DEA model was extended to be the multi-objective one.

工程项目某一分期实施阶段的无效率可能导致整体计划的无效，为了克服传统DEA模型评价这类阶段性问题的局限，及时发现并调整工程项目的无效阶段，借鉴具有不可控要素DEA模型的思想建立了多阶段DEA模型，同时考虑到单目标DEA模型的不足，进一步将多阶段DEA模型扩展为多目标模型。

DEA：数据加密算法

DEA:数据加密算法(Data Encryption Algorithm)数据加密算法(DEA)是被定义作为美国政府数据加密标准的一部分的对称块密码. DEA使用一个64位的密钥,其中的56位是独立选择的,8位是校验位,和映射一个64位块到另一个64位块.
