| 中文摘要: |
| 结合水资源配置过程中的有效性、公平性和可持续性三类原则，针对其中水资源、社会、经济和环境等指标因素的不确定性，构建基于区间灰数的多目标水资源配置模型。在利用区间灰数预测方法计算各规划年指标数据的基础上，以经济效益最大、污水排放量和缺水量最小为有效性目标，以水源在各子区域分配公平的基尼系数最小为公平性目标，以距离协调度模型来评价水资源分配的可持续性目标，将不确定的多目标问题转化为确定的单目标问题，并采用改进的类电磁学算法对模型进行求解。最后将此模型应用于实例，其结果表明，模型的结构合理，算法简单高效，配置结果合理。 |

| Combined with the three principles of efficiency，fairness and sustainability in the process of water resources allocation， the multi-object water resources allocation model based on the interval grey numbers is built in view of the uncertainty of the water resources，society，economy，environment and other index factors. On the basis of using interval grey numbers prediction method calculating the data of the index of the planning years， this model makes the maximum economic benefit， minimum wastewater and water shortage as the effectiveness goal， the minimum Gini coefficient distributed equally in the branch areas of the water resources as the fairness goal， and a distance coordination model to evaluate the sustainability goal of water resources allocation. It turns the uncertain multi-objective problem into a certain single objective one，and calculates by using the improved algorithm of electromagnetism. Finally，the model is applied to certain northwest area. The result shows that the structure of the model is reasonable and the method is simple and effective. |
