线性规划梯度法（LPG）是环状给水管网优化设计的重要方法，但算法复杂、收敛速度慢限制了其应用。本文将环状配水系统的设计问题视为变系数线性规划问题。首次精确推导了给水管网费用对管流的导数。提出了一种有效的求解最优管流的迭代算法。给出了一个算例。结果表明，新算法比现有算法具有更好的收敛性。
Linear programming gradient (LPG) method is an important method for the optimum design of looped water distribution systems, but the complex algorithm and slow convergence restrict its applications. In this paper, the design of the looped water distribution system is considered as a linear programming with variable coefficients. The derivatives of the cost with respect to pipe flows for water distribution system are deduced accurately for the first time. An efficient iterative algorithm for searching the optimum pipe flows is developed. An example is presented. It is shown that the new algorithm has better convergence than present algorithms.
