| 中文摘要: |
| 本文针对城市供水调度系统中存在的不确定性与复杂性，运用区间两阶段随机规划的方法，建立了多水源联合供水调度的优化模型。该模型以供水调度系统成本最小为目标函数，引入概率分布及区间数表示不确定性，模拟了地表水源、地下水源、外来水源等多种水源联合供水过程，并对多种水源的调水目标进行优化。以区间形式给出优化结果，为决策者提供宽裕的决策空间。利用该方法，可充分考虑系统中不确定因素对系统成本的影响，更真实的反映多水源联合供水系统的实际情况。 |
| 英文摘要: |
| An interval parameter two stage stochastic optimization model was developed for dispatching the multiple sources water systems for urban supply under the conditions of uncertainty. In the model the minimal system operation cost was regarded as the objective function and the probability distribution and interval parameters were used to express the uncertainty of water supply. The process of combined water supply from multiple sources, including the surface water, groundwater and water obtained from external system, was simulated and the objectives of water from various sources were optimized. The optimized results provided for decision maker was in the form of interval parameter. By using this method, the influence of uncertainty on system operation cost can be considered sufficiently and the situation of combined water supply can be actually reflected. |
