| 摘 要： | 模仿现实评价过程，提出烟气脱硫技术综合评价的改进模型。为便于考察参评技术的技术经济可行性及其对外部环境造成的威胁，改进模型把评价指标分成了两大类，即具有可补偿性的普通指标和具有独立否决权的特殊指标。改进模型根据指标隶属度的线性加权和与加权积公式分别计算了普通指标与特殊指标的测度效果，将上述测度效果进行几何平均得到参评技术的综合评价结果。为增强指标权重的客观性，改进模型还利用熵权计算了普通指标在数值意义下的相对重要程度，并据此调整了普通指标的事先权重，获得了包含专家偏好和指标取值信息的普通指标的最终权重数值。应用该模型可得到符合实际的评价结果。 |

| Abstract: | This paper presented an improved mathematical model for comprehensive evaluation of flue gas desulphurization(FGD) technologies to simulate the practical assessment.In order to compare technical and economical feasibility and impacts of given FGD technologies on environment effectively,the improved model classified the evaluation indicators into two categories i.e.common factors with compensable attributes and special factors with independent veto rights.Then,the model calculates synthetic effect measures of common factors and special factors respectively according to corresponding factors subordination degree's liner-weight-sums and weight-products,besides,the model calculates integration result of each technology according to geometric mean of above-mentioned synthetic effect measures.In addition,to reinforce common factors' weights objectivity,the model applies entropy weights to calculate common factors' relative importance in the sense of factors' numerical values,and gets ultimate weight values of common factors which implicate expert preferences and factor values information by means of adjusting previous weight values of common factors with the help of their entropy weights.The application shows that the model can be used to obtain the consistent results with practice. |
