| 摘 要： | 本文描述了由元级ES框架和目标级ES框架组成的两级骨架工具系统MESl。简介了我们提出的元知识表示、目标知识表示方法和两种基于证据理论的不确定性处理模型以及它们的新特点。MESl可以支持多种不确定性处理模型,具有高效的多级知识搜索结构,对问题求解能实施更加有效、有力、灵活的控制。在MESl的支撑下已建造了5个石油勘探领域的专家系统,它们都用于生产并取得了很好的效果。

| Abstract: | MES1 is a two level skeletal system which consists of a meta level expert system frame and a object-level expert system frame. In this paper, we introduce the methods of representing meta-level and object-level knowledge and two kinds of uncertainty processing models based on the theory of evidence. MES1 can support different kinds of uncertainty processing methods and provide a more efficient, powerful and flexible control mechanism for problem solvinng. Five expert systems in the field of oil exploration and development have been built with MES1 and good results have been gained in applications. |
