供水管网模糊优化设计数学模型研究

供水管网优化设计通常具有模糊性，即影响管网优化设计的某些因素难以准确确定。针对这一特点，建立了供水管网模糊优化设计数学模型。通过变换，将模糊线性规划问题转化成一般线性规划问题，用单纯形法求解。根据所建立的管网模糊优化设计模型，可确定模糊环境下供水管网优化设计方案，与普通线性规划问题相比，该方法使设计结果更为经济合理。

Study on the Fuzzy Mathematic Model of Water Networks Optimal Design

There are usually some fuzzy factors in the designing of water networks, i, e, the factors that affect the design result of the networks are difficult to determined, Aiming at this special feature, this paper has built a fuzzy optimal design model for the networks, The fuzzy linear programming is changed into general linear programming and solved by simplex method. The model has been used in the designing of the small town water networks with some fuzzy factors. Comparing with the general linear programming, this method is more rational.
