基于区间数判断矩阵群信息的集结方法

The Method of Aggregating Group Information under Interval-Number Judgment Matrixes

对群信息的有效集结是群决策过程中重要的技术问题之一.不同类型的群信息有不同的集结方法,针对区间数判断矩阵的群信息,为了能充分挖掘和利用这类群信息的信息资源,提出了将群中各成员的区间数决策信息集结为具有一定可靠度的确定信息的方法原理,给出了这类群信息集结值可靠度的计算模型和修正流程,并通过一个算例验证了该方法的有效性.结果表明,该方法是集结区间数判断矩阵群信息最有效的方法之一.

The effective aggregation of group information is one of the most important technical problems in the process of group decision-making. Different types of group information need to have different aggregating methods. To fully unearth and use the information resource of interval-number group information, a new method of aggregating group information under interval-number judgment matrixes from every member in the decision group into the definitive number decision information with certain reliability was put forward, and the model of computing and revising the reliable degree of the aggregated values of group information was established. Besides, the effectiveness of the method was tested by an example. The result showed that the method was one of the most effective methods for aggregating group information under interval-number judgment matrixes.
