模糊数学理论在泵站工程老化评价中的应用

Application of fuzzy mathematics to aging assessment of pumping station engineerings

为研究我国泵站工程的老化程度,运用模糊数学中的相关理论,建立了泵站工程老化评价的数学模型.该模型通过递阶层结构评价体系的建立、因子权重的确定、各种定性指标和定量指标的数字量化,并结合综合评价理论的应用,形成了一种建立在模糊综合评价理论基础上、适于泵站工程采用的新的评价系统.详细介绍了评价模型的建立方法和步骤,最后以算例说明了该法在泵站工程老化评价中的应用.

In order to investigate the aging degree of pumping station engineerings in China, the pertinent theory of fuzzy mathematics is applied to establish a mathematical model of the aging assessment of pumping station engineerings .With the establishment of the assessment system,the ascertainment of the factorial weighting,the numeric quantification of various qualitative factors and quantitative factors and the application of fuzzy assessment, a new assessment system, which based on the theory of fuzzy mathematics and is suitable to the aging assessment of the pumping station engineerings, is formed. An elaborate introduction to the establishment of the means and process of the assessment model has been made. Finally a pratical example is given to show concretely the means and process of the assessment system .
