DSS中混合推理机制的研究

为了在决策支持系统(DSS)的问题求解过程中丰富领域知识,加强求解方法和领域问题的关联,总结了目前决策支持系统常用的几种推理机制并阐述了它们之间的互补性,提出了以知识为核心的混合推理方法,其中领域知识与问题求解方法分别被划分在领域层和推理层中,提高了知识和方法两方面的重用性,改善了单一推理求解的不足,为应用中间件技术进行组件化的系统开发提供了理论指导。

Research on Multi- Reasoning Mechanism for DSS

For reinforcing combination between PSM(problem solution method)and domain problems and enriching domain knowledge in problem solution processess,this paper sums up the reasoning mechanisms in DSS and sets forth the complement each other,then suggests a knowledgeoriented multireasoning method,in which domain knowledge and PSM are divided into domain layer and inference layer respectively,that can promote reuse of both knowledge and method and can serve as guidelines for the development of componentbased DSS.
