摘要
农村中小型泵站是农村水利工程中结构最复杂的水工建筑物。传统的评价方法主要是模糊层次法,应用十分广泛,但是指标易受量纲影响,指标权重受人为影响大。为避免这一问题,在传统评价模型基础上,建立了投影寻踪聚类评价模型,通过加速遗传算法解决非线性规划问题。根据计算出的投影值确定老化程度,为泵站工程改造提供依据。
Rural pumping station is the most complex structure in rural water conservancy project.The traditional method of evaluation is the fuzzy hierarchy method,which it is widely used.In order to solve the impact of dimension and index weight of evaluation indexes,projection pursuit cluster model is used in the evaluation model.Combining with the accelerating genetic algorithm,aging degree of the pumping stations can be determined according to the projection value of each pumping station.Through the model calculation,compared with the traditional method,the method is feasible.
