Optimization on Long-distance Water Supply Pipeline Based on Decomposition-dynamic Programming Aggregation Method

以输水管道工程总投资最小为目标,构造长距离输水管道优化设计数学模型,并采用大系统分解-动态聚合方法进行求解。结果表明,该方法既充分利用动态规划的全局寻优能力,又能获得具有标准管径的最优管长组合方案,是进行长距离输水管道系统优化设计的一种可行而有效的新方法。

The mathematieal model of optimal design for long distance water supply pipeline was construc- ted by taking the minimal total investment cost as objective function, and the decomposition-dynamic pro- gramming aggregation method was applied to solve the mode/above. The results indicated that the decom- position-dynamic programming aggregation method was feasible and effective, which could make full use of dynamic programming global optimization ability and ensure that the obtained solution was the optimal de- sign solutions with optimal length combinations of standard diameters.
