Abstract:The consensus degree is an important basis for the consensus identification process, which directly affects the consensus process of the decision-making environment, but one of the important reasons why the consensus degree has been difficult to measure is the heterogeneity of the decision-making group. In the field of scientific and technological project review, the lack of expert consensus measurement methods also hinders the review and consensus of non-consensus projects to some extent. Therefore, this paper proposes an expert consensus measurement method based on the review data of scientific and technological projects. Aiming at the problem that expert heterogeneity is difficult to measure, this method first determines the expert review preference through historical review data, secondly uses knowledge such as expert publication volume and H-index to calculate expert authority, and then uses expert research direction and review project research content to obtain topic coverage, and the three combine to obtain expert weight. For the calculation of consensus degree, the consensus scheme is calculated by using the expert weight, and the consensus scheme is calculated by the mutual inverse matrix consensus decision model, and then the similarity between the expert scheme and the consensus scheme is calculated by the overlap of ranking bias to obtain the consensus degree. The expert consensus measurement method proposed in this paper not only combines the historical information of experts and current information, but also considers heterogeneity indicators such as expert authority and research direction, which are easy to lead to consensus bias. Finally, the effectiveness and rationality of the method are verified by comparative analysis.
