D-S证据理论在决策支持系统中的应用

D-S证据理论提供了一种解决多数据源不确定信息推理和融合的有效方法。证据理论能够对各自独立的证据加以综合给出一致性结果,并能处理具有模糊和不确定信息的合成问题,最终达到信息互补。与其他推理方法相比更符合人类思维决策过程。为此,提出一种基于D-S证据理论的灾害决策支持方法,并根据试验结果验证了该方法的有效性和可行性。

Application of D-S Evidence Theory to DSS

The D-S evidence theory, which provides a method of efficiently solving uncertain information reasoning and integration of the multiple data source, can synthesize independent evidence and give consistent results. In addition, it also deals with synthesis problems of fuzzy and uncertain information in order to achieve complementary information. Compared with other reasoning methods, this evidence theory is much more similar to the decision process of human-beings. Therefore, in this paper, a disaster decision method based on DS evidence theory, has been proposed, and its effectiveness and feasibility have also been proved, according to the experimental results.
