摘要: 为实现产品智能设计中计算性问题和推理决策性问题的求解以及二者的有效结合,提出一种支持产品智能化设计的知识服务方法,即包括知识服务策略的制定和知识环境的构建两个方面。该方法通过分析设计知识自身特点以及与设计过程之间的关系,将设计知识分为业务领域、经验规则、实例方案和算法模型4种类型,并针对不同类型知识制定相应的服务策略;基于知识模板和组件模板对不同类型的知识进行形式化描述,并给出基于本体的设计知识语义建模流程;通过方案评价、方案修改将设计知识融入到基于实例推理活动中,实现知识的辅助决策;对设计工具进行集成和过程封装,实现了自动化计算。设计开发了基于知识的智能设计系统,并以枪管为对象进行了实例验证,证明了所提方法的有效性。

Abstract: To solve the problems of computation and reasoning decision in the product intellectualized design and achieve a combination of both, a knowledge service method for supporting product intellectualized design is proposed, which includes the development of knowledge service strategy and the construction of knowledge environment. The design knowledge is divided into four types, i.e. business domain, empirical rule, instance scenario and iteration calculation, by analyzing the features of design knowledge and the relationship between it and design process. A appropriate service strategy is developed for the different types of knowledge, and the formal descriptions of them are given based on knowledge and component templates. An ontology-based semantic modeling process of design knowledge is presented. On this basis, through evaluation and modification of scheme, the design knowledge is integrated into the instance-based reasoning activities, and the automated computation is achieved by tools integration and procedure packaging. A knowledge-based intelligent design system is developed. The proposed method is demonstrated by taking a gun barrel for example. The result shows that the method is effective.

Key words: artificial intelligence, knowledge service, knowledge reuse, reasoning decision, barrel design
