随机规划在泵站树状给水管网优化中的应用

泵站树状给水管网流量具有随机性,而这种随机性变化会直接影响管网的建设费用和动力费用.针对这-特点,应用随机规划原理,建立泵站树状给水管网机会约束模型,编写基于随机模拟的遗传算法程序求解该模型.机会约束模型能较客观地反映该管网的实际工况,使优化设计结果更符合实际.

Application of Randomizing Planning in Optimization of Network of Dendritic Service Pipes of Pumping Station

The lfow of network of dendritic service pipes of pumping station has random, but the random change can directly affect the construction costs and power costs of pipe net work. Based on this characteristic, the paper applies the principle of randomizing planning, sets up chance-constrained programming of network of dendritic service pipes of pumping station, compile the inheriting arithmetic procedure and solve the model. The opportunity and restricted model can objectively relfect the actual work condition, so that the optimization design result can accord with the practice.
