摘要
给出一种基于层次分析和灰色分析的水质风险评价方法:用层次分析法计算水质评价因子权重,用带权重的灰色分析法评价多因素影响下的纯净水水质。结果表明,用层次分析法为评价因子赋权能够全面考虑各评价因子对水质影响的不同;用灰色分析法计算纯净水的风险度值和风险级别,考虑了水质评价中的模糊性和不确定性,比较符合纯净水水质评价的实际情况。
A water quality risk assessment method based on the analytic hierarchy process （AHP） and the gray analysis method was proposed. In the model, the AHP method was used to calculate the weights of the assessment factors, and the gray analysis method was used to assess the quality of pure water under the influence of various factors based on the weights. The reaults showed that the use of AHP method in computing the weights of assessment factors can offer a comprehensive consideration of different affects of various factors on water quality. Besides, the gray analysis method in calculating the risk value and risk category of pure water quality considered the vague and uncertain factors, and met the real situation of pure water quality assessment.
