提出了一种基于启发式线性规划的给水管网最小费用规划设计方法。该方法能够分析广泛的需求模式和管道失效组合。通过使用Hardy-Cross网络求解器技术，在整个过程中确保了液压一致性。该程序还可扩展用于现有网络系统的扩展或加固。虽然用于减小约束集大小以使程序能够处理大范围加载条件的技术并不能保证全局最优性，但实现了实用的“合理的”最优性。通过对一个新网络的设计和对现有网络的扩展，验证了该方法的有效性。在现有网络问题的扩展中，所获得的解决方案比以前公布的任何解决方案都要便宜。
A heuristic linear programming-based procedure has been developed for the least cost layout and design of water distribution networks. The methodology is capable of analyzing a wide range of demand pattern and pipe failure combinations. Hydraulic consistency is ensured throughout the procedure through the use of the Hardy-Cross network solver technique. The procedure can also be extended for use in the expansion or reinforcement of existing network systems. While the techniques used to reduce the size of the constraint set to enable the procedure to handle a wide range of loading conditions do not guarantee global optimality, a pragmatic “reasonable” optimum is achieved. The method is demonstrated by application to the design of a new network and the expansion of an existing network. In the expansion of the existing network problem the solution obtained was less expensive than any previously published solution.
