Organization and Management of the Knowledge Base for Engine Diagnosis

本文研究了发动机诊断领域的知识库组织与管理问题.讨论了发动机领域级多种不同深度知识源的表示与获取问题;提出了知识库组织的分层分块管理策略.

The organization and management of the knowledge base for engine diagnosis is studied in this paper. Several problems about the representation and acquisition of multiple knowledge sources with different depths, such as heuristic experience, mapping relation in hierarchical causalities, pathbased physical description and state knowledge at the engine domain level are discussed. A layered and blocked strategy is proposed for the organization and management of such an integrated knowledge base. A technique for layered control and accession, and blocked organization and management is described. This technique has been applied to a knowledge based system for engine diagnosis (KBSED) recently developed by the authors.
