Study on Incompatibility Problems SolvingBased on Extension Theory

Yang Chunyan

Strategic Study of CAE 2007, Volume 9, Issue 10, Pages 36-39

Abstract:

Based on the study of single-characteristic incompatibility problem and the transformation of solving it, the structure, judging methods and solving methods of multi-characteristic incompatibility problem are studied.

Study on the Universality of the Normal Cloud Model

Li Deyi,Liu Changyu

Strategic Study of CAE 2004, Volume 6, Issue 8, Pages 28-34

Abstract:

The distribution function is an important tool for the study of the stochastic variances.While the fuzzy theory is widely used, the completely certain membership function which has no any fuzzinessonly broaden the formation conditions of the normal distribution but also make the normal membership functionbe the expectation of the random membership degree.

Extension Knowledge Base System and Its Application

Li Lixi,Li Jia

Strategic Study of CAE 2001, Volume 3, Issue 3, Pages 61-64

Abstract:

Knowledge base system (KBS) is an organization to store and manage a lot of knowledge. Extension knowledge representation (EKR) based on extension theory is presented in this paper. Two key concepts of EKR are the described——formal semantic of EKR and the formal representation of contradictory problem solving. The basic element of the former is knowledge matter-element model. In addition, the Specific Extension Inference (SEI) corresponding to EKR is also reviewed. The feature of SEI is correlative inference, which has been implemented by computer. Finally, the feature and the frame of extension knowledge base system (EKBS) are proposed. EKBS uses EKR and is an excess of traditional KBS. It is composed of goal system, condition system, common knowledge base, categorized knowledge base, inference machine and knowledge base management system.

Keywords： extension theory non-compatible knowledge base
