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。
