摘　　要： 在建设项目可行性论证中方案评价与选择的正确与否决定了建设项目投资效益的优劣。为克服目前可行性论证中单指标评价和评价指标体系不完善的弊端,本文利用数据包络分析(DataEnvelopmentAnalysis,DEA)方法,结合项目建设过程中的实际案例——不同规模炼油厂进行分析比较,对建设项目多方案的选取进行了多目标综合评价。在评价中利用基础数据和数据包络分析模型进行分析,可获得不同方案投资效率的相对有效性以及方案的优劣顺序,同时利用数据包络分析模型能够反映出更多的有关方案内部的信息,如无效方案的主要影响指标及不同指标对方案的影响程度,便于决策者对方案的投入与产出指标进行调整和分析,为决策者的科学决策提供依据。 The evaluation of construction projects is of great importance in feasibility studies, since it is related to the investment performance. In order to overcome the disadvantages of single index or inadequate indices in the feasibility study, the method of Data Envelopment Analysis is applied to the multi-objective comprehensive evaluation of different projects during the feasibility study in order to select the optimal projects. The DEA model can be employed to evaluate the relative efficiency of different projects, to decide the optimal orders of construction projects, and to offer more intimate information of the projects concerned that decision-makers would want to know about. Besides, it is convenient for decision-makers to get more satisfied projects by adjusting the index system of input and output. Thus DEA model provides a scientific reference for decision-makers.
