基于模糊物元和墒权迭代理论的水库兴利调度综合评价方法
|
摘要
基于墒权迭代理论和模糊物元法建立多目标水库兴利调度的综合评价方法。该评价方法不仅可直接确定评价目标的无偏好权重,还能根据可行方案综合贴近度大小决定最优方案。由于评价过程中隐含了水库兴利调度的特点及专家和水库管理人员的经验意见,因此有效地避免了评价目标权重及优选方案确定的人为偏好性。应用该方法对浙江省悬渚水库11种可行兴利调度方案进行了评价,确定的最优调度方案与模糊模式识别交叉迭代模型评价结果一致,且明显优于现行调度方案,验证了该方法切实可行且可操作性强。
On the basis of fuzzy matter-element theory and entropy objective iteration algorithm a comprehensive evaluation method of reservoir dispatch for beneficial purpose is established.By using this method not only the without preference weight of the evaluated object can be directly determined,but also the best scheme can be found according to the amount of approach degree of every possible scheme.Since the characteristics of reservoir dispatch for beneficial purpose and the objective intention of decision-maker as well as the natural property of alternative are implied in the process of evaluation,the effects of artificial preference on weight of evaluation object and determination of the best scheme can be effectively avoided.The proposed method is applied to evaluate the 11 dispatch schemes for beneficial purpose of the Xuanzhu Reservoir,Zhejiang Province.It is found that the best scheme determined by the proposed method is the same as the scheme selected by fuzzy pattern-recognition crossover iteration model and much better than the current used dispatch scheme.
