Study and Implementation of a Knowledge-Based Intelligent Scheme Design Support System KBIDSS/V1.0 for Aerospace Model Product

从导弹总体设计的需要出发 ,分析了导弹总体方案设计的特点。介绍了一种智能化方案设计推理决策系统KBIDSS/V1 0 ,该系统是在一个面向对象的数据库管理系统基础上开发的。重点研究了面向对象的集成化知识表示、问题的推理求解与方案评价等模块的实现。在KBIDSS/V1 0中 ,问题推理的求解采用基于实例的推理 ,辅之以基于规则的推理模式。论述了KBIDSS/V1 0系统的设计思想和各个主要模块的功能 ,并重点介绍了实例推理器的设计与实现。最后 ,对该系统进行了分析和评价。

A knowledge-based intelligent scheme design system named KBIDSS/V1 0 is introduced in the paper. Some key issues such as object-oriented knowledge representation, inference are studied intensively. In KBIDSS/V1 0, a case-based reasoner collaborates with a rule-based reasoner on problem solving. The major components of the system are descirbed and the metaobject-guided case-based reasoning strategy related to scheme design for areospace model products is discussed in detail. Finally, this system is analized and enaluated with the evaluation criteria for knowledg-based design support system.
