| 摘 要： | 模糊综合评价在理论和应用中的关键问题是如何合理确定各评价指标的权重。为此,提出了直接根据单指标相对隶属度的模糊评价矩阵,构造层次分析法中的判断矩阵,用以确定各评价指标权重。给出了用加速遗传算法检验和修正判断矩阵的一致性和计算判断矩阵各要素的权重的模糊综合评价模型(AHP＿FCE)。实例表明,AHP＿FCE方法简便和通用,计算结果较为客观和稳定,在系统工程理论和实践的各种综合评价中具有推广应用价值。 |

| Abstract: | The key problem of fuzzy comprehensive evaluation both in theory and practice is how to reasonably quantify the weights of different evaluation indexes in the fuzzy system. In this paper a new approach is proposed to directly construct the judgment matrix in analytic hierarchy process according to the fuzzy relative membership degree matrix of single evaluation index. On this basis, a new method namely analytic hierarchy process-fuzzy comprehensive evaluation (FCE-AHP), which can be used to check and correct the in consistency of judgment matrix by means of accelerated genetic algorithm and to calculate the weight of the elements in the judgment matrix, is established. The application shows that this method is universal, stable and the calculation result is objective. |
| Keywords: | fuzzy comprehensive evaluation analytic hierarchy process judgment matrix accelerated genetic algorithm |
