摘　　要：基于多水源灌溉系统,考虑系统水资源分配并确定管网拓扑结构与连接管道尺寸,以最小化系统流量分配成本和管道安装成本之和为目标函数建立混合整数规划模型。设计一种混合启发式算法将局部搜索与精确算法结合,协同优化管网布置与管网设计两个阶段,分析各节点之间的连接情况与连接管径,并为需水节点分配流量。通过不同规模的测试算例验证协同优化算法能有效降低多水源灌溉系统的建设成本。Water-saving irrigation is the key to accelerating agricultural modernization and improving irrigation efficiency.A mixed integer programming model is established for a multi-source irrigation system with the objective of minimizing the cost of system flow distribution and pipe installation,to determine the pipe network topology and connecting pipe sizes,where the distribution of water flow is considered.A hybrid heuristic algorithm is designed to integrate local searching with an accurate algorithm.It coordinates the optimization of the layout and design for pipe networks in two stages.The connections between nodes and connecting pipe diameters are analyzed,while the flow to demand nodes is allocated.Test examples with different scales verifies the effectiveness of the proposed coordinated optimization algorithm in reducing construction cost of a multi-source irrigation system.
