基于AHP群决策法的配电网规划方案综合决策

Comprehensive decision making of distribution network planning based on group AHP

配电网规划方案的综合决策过程不可避免地会受到主观意识左右,从而影响决策结果的可靠性,因此尽量降低主观因素对配电网规划方案综合决策的影响对指导电网的合理建设和改造具有重要意义。基于层次分析法引入群决策理论,通过对各决策组成员意见进行一致性分析,合理反馈,以得到各成员动态权重,进而形成客观的、具有代表性的聚合决策意见,为最终的方案排序提供了依据,增强了决策过程的客观公正性,提高了决策结果精度和可靠度。实例计算表明了该方法的正确性,且简洁易实现,具有较好的现实意义。

The process of comprehensive decision making of distribution network planning is inevitably affected by subjective cnnsciousness, which would reduce the reliability of decision. So minimizing the impact of subjective deviation on decision making as much as possible is important to reasonable grid construction and reformation. In this paper, group decision making based on AHP （GAHP） is introduced, which can realize consistency analysis of each decision group members＂ opinion and work out the dynamic weight of each members, and then torm an objective, representative aggregation opinion. It provides a new method for the final program sorting. GAHP could enhance the objectivity and fairness as well as improve the accuracy and reliability of the results of decision making. The example shows the correctness and simplicity of the proposed GAHP.
