【摘要】：针对群决策问题,提出了一种基于群体一致性强度的虚拟专家意见逐步集结规划的方法。首先将两个专家的偏好信息集结为序关系值向量,将该次集结结果作为一个"虚拟专家"给出的判断信息,然后吸收下一个专家的意见成为新的虚拟专家,依此类推,直到最后一个专家参与决策。引入虚拟专家的群体一致性强度保证群体结果趋向一致,其中一致性强度和虚拟专家的权重依赖于所包含的个体专家的人数。个体人数越多一致性强度和权重就越大,从而体现了少数服从多数的原则。该方法将多专家的复杂群决策问题转化为低复杂度的多阶段二人决策问题,并保证了群体结果的一致性。最后,通过一个算例验证了方法的有效性。
[Abstract]:Aiming at the problem of group decision-making, puts forward a method of virtual expert judgment based on group consistency intensity gradually concentrated planning. First preference information of the two experts gathered for ordering vector, the gathering as a result of judgment information is a "virtual expert", and absorb the next expert opinion a new virtual experts, and so on, until the end of an expert to participate in decision making. Strength of group consensus virtual expert group to ensure consistent results, the number of individual experts the weight consistency depends on the strength and virtual experts included. The individual number consistency strength and weight is bigger, so embodies the principle of majority rule. The method of complex multi expert group decision problem is transformed into the multi stage low complexity two decision problems, and ensure the consistency of the results of the group. Finally, an example is given to verify the effectiveness of the method.
