在群组评价问题中,称评价参与者(即节点集)及参与者之间的评价关系构成群组评价局部环境,即评价群体的网络结构。将评价局部环境看作是一个有限状态、不可约且非周期性马尔可夫过程,使得群组评价问题水平维度的评价局部环境基于时间维度进行拓展,证明参与者对评价关系的调整可以改善群体网络结构的稳定性;具有评价关系的参与者状态正相关;参与者不满意效用状态持续时间的增加降低了其达到满意效用状态的概率。在此基础上,讨论以被评价对象为主要研究对象设置群组评价方法,根据三种常见的评价局部环境状态,考察评价群体的群体性行为或认知趋势性特征,在此基础上讨论评价目标的可执行性。允许有关被评价对象的新信息注入群组评价系统,在长期分析评价群体的群体性评价行为的趋势特征,据此构建面向评价局部环境的群组评价方法,分析评价目标的可执行性,以期使群组评价行为具有稳定性和可预见性。
In the group evaluation problem, the evaluation relationship between the evaluation participants (ie node sets) and the participants constitutes a group to evaluate the local environment, ie, the network structure of the evaluation groups. The evaluation of local environment is regarded as a finite, irreducible and non-periodic Markov process, which makes the evaluation of local environment in the horizontal dimension of the group evaluation issue expand on the time dimension. It is proved that the adjustment of the evaluation relation by the participants can improve the group The stability of the network structure; the status of participants with evaluation relationship is positively correlated; and the dissatisfaction of participants with the increase of duration of utility reduces the probability of reaching the satisfactory utility state. On the basis of this, we discuss how to set up a group evaluation method with the object of evaluation as the main research object, and examine the group behavior or cognitive tendency characteristics of the evaluation groups based on the three common evaluation of the local environmental conditions. Based on this, The target’s enforceability. Allow the new information about the object being evaluated to be injected into the group evaluation system and analyze and evaluate the trend characteristics of the group evaluation behavior in the long term. Based on this, construct the group evaluation method for evaluating the local environment and analyze the feasibility of the evaluation target. Make group evaluation behavior is stable and predictable.
