| 中文摘要: |
| 针对工程方案设计的主观性问题，探讨了模糊综合评价与数据包络分析(DEA)理论在工程方案设计选择中的应用。将综合评价指标分为可定性分析指标和可定量分析指标，不同的评价指标采用不同的评价方法进行分析。对于可定性分析指标，采用离散语言值标尺确定单因素评价向量；对于可定量分析指标，应用数理统计与模糊数学相结合的方法，根据离散抽样模型，定量计算单因素评价向量。通过定性与定量分析相结合，采用模糊综合评价进行工程方案设计。同时将DEA分析理论应用于工程方案设计问题，构建了适合于方案设计的DEA模型，研究了设计方案的相对有效性。实例证明，该方法在水利设计等工程领域具有很强的实用性。 |

| The fuzzy comprehensive enaluation and data envelopment analysis (DEA) are applied to select the engineering scheme. The evaluation indexes are divided into two kinds: quantitative and qualitative. The vectors of qualitative indexes are obtained from discrete value scale evaluation and the vectors of quantitative indexes are derived from discrete sample model based on the principle of statistics and fuzzy mathematics. By using the fuzzy comprehensive evaluation the best engineering scheme can be determined qualitatively and quantitatively. At the sametime, the relative efficiency of project scheme is studied by DEA theory. The selection of the scheme for a retaining structure is given as an example for demonstration. |
