基于本体和知识组件的自行火炮设计知识表示技术

自行火炮各类设计知识如果未得到有效地组织和表示,会导致设计过程中难以重用已有设计知识。针对该问题,提出了一种基于本体和知识组件的知识表示方法。通过分析自行火炮设计知识的表示需求,研究自行火炮设计本体的组织方式和知识组件的开发策略,构建自行火炮设计本体与知识组件的映射关系,实现自行火炮设计知识的表示。在此基础上,通过开发专用知识检索系统,使设计人员能快速重用已有的设计知识。以中大口径压制自行火炮为例,实现了设计知识的表示和重用,验证了所提出方法的可行性和有效性。

Design Knowledge Representation Technique for Self-propelled Artillery Based on Ontology and Knowledge Components

For the problem of that the various design knowledges of self-propelled artillery have not been organized and represented effectively and the existing design knowledge cannot be reused simply during the design process, a knowledge representation method is proposed based on ontology and knowledge components. The organization mode for design ontology of self-propelled artillery and the developing strategy for knowledge components are studied on the base of analyzing the representation requirement of design knowledge of self-propelled artillery, and the mapping relationships among design ontology and knowledge components are established. The representation of design knowledge of self-propelled artillery is achieved. On this basis,a special knowledge retrieval system is developed for designers to quickly reuse the existing design knowledge. The representation and reuse of design knowledge are implemented by taking large-caliber self-propelled artillery for example. The result shows that the proposed method is feasible and valid.
