【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]:In order to solve the computational problems and reasoning decision-making problems in product intelligent design and the effective combination of the two, a knowledge service method supporting product intelligent design is proposed, which includes two aspects, namely, the formulation of knowledge service strategy and the construction of knowledge environment. The method by analyzing the relationship between the characteristics and the design knowledge and design process, the design knowledge is divided into business areas, experience rules, instance scheme and algorithm model of 4 types, and for different types of knowledge to formulate the corresponding service strategy; knowledge template and component templates for the formal description of different types of knowledge based, and given the design knowledge semantic modeling process based on ontology; through project evaluation, scheme design will modify knowledge into case based reasoning activities, to achieve decision-making knowledge; integration and process of packaging design tools, automated calculation. An intelligent design system based on knowledge is designed and developed, and an example is given to verify the effectiveness of the proposed method.
