【摘要】 根据系统可靠度的理论,提出用最小割集的方法求节点可靠度,以此来分析给水系统的可靠性。提出一个基于可靠性的给水系统优化模型,将模型的目标函数和约束函数均用一阶Taylor级数展开,分步寻优,逐次线性逼近来求解这个高度非线性问题,大大缩短了优化搜寻所需的计算时间,使给水系统基于可靠度的优化模型运用于实际的给水系统乃至大型给水系统成为可能。更多还原

【Abstract】 According to the theory of system reliability,node reliability can be worked out by minimum cut set,which is used to analyze the reliability of water systems.The paper proposes one optimal model based on reliability for water distribution model,that is to expand the model’s objective function and constraints in the first Taylor order to search the model step by step,gradually solve the difficult nonlinear problem,and greatly reduce the optimal time.Thus it is very likely for the model based on reliability to be used in the practical water distribution system and even large water distribution system.更多还原
