基于評價信息滿意度的群體信息集結(jié)方法

摘要： 針對群體評價中如何對各評價者的評價信息進(jìn)行集結(jié)的問題,文章提出了一種基于評價信息滿意度的群體信息集結(jié)方法,該方法改變了以往研究中評價者權(quán)重固定不變的思想,而是綜合考慮評價者對評價問題的總體認(rèn)知情況和對評價信息中各元素的認(rèn)知情況從而確定針對不同元素集結(jié)時的評價者權(quán)重,旨在使集結(jié)的群體評價信息更趨于合理和公正。首先設(shè)定評價情景,提出研究假設(shè)并給出評價信息滿意度的定義;然后根據(jù)不同的評價信息給出評價信息滿意度矩陣的確定方法;根據(jù)各評價者的評價信息滿意度矩陣確定各評價者在集結(jié)過程中的權(quán)重矩陣;按照各評價者的評價信息滿意度的大小對評價信息進(jìn)行集結(jié)。最后,用一個算例檢驗了方法的有效性。
In order to address how to aggregate individual evaluator's evaluation information in the group evaluation,this paper proposes a group information aggregation method based on the evaluation of information satisfaction.This method changes the idea that the weight of evaluators is fixed in previous studies.Instead,the evaluators weight for the aggregation of different elements is determined by considering the overall cognition of evaluators on the evaluation problem and the cognition of each element in the evaluation information,so as to make the information of group evaluation more reasonable and fairer.Firstly,the paper sets up the evaluation scenario,proposes the research hypothesis,and gives the definition of evaluation information satisfaction.And then,according to different evaluation information,the paper gives the determination method of evaluation information satisfaction matrix,depending on the evaluation information satisfaction matrix of each evaluator to determine the weight matrix of each evaluator in the aggregation process,and aggregating the evaluation information according to the degree of evaluation information satisfaction of each evaluator.Finally,the paper offers an example to verify the effectiveness of the proposed method.
