摘要虽然已经有了相当多的计算机辅助概念设计研究,但所提出的方法大多是特定于领域的,只能实现能量流处理系统的概念设计。因此,本研究致力于开发一种通用的(即独立于领域的)基于知识的方法,它可以在广泛的多学科解空间中搜索适合于所需物流处理功能的解原则,而不会偏向于设计者熟悉的解原则。它首先提出了一种基于本体的方法,以形式化和明确的方式表示所需的物流处理功能。然后,提出了一种基于规则的方法,以一种通用而灵活的方式表示已知解原理的功能知识。在此基础上,提出了一种基于模拟的检索方法,该方法可以为所需的物流处理功能寻找合适的求解原则。所提出的方法已作为计算机辅助测试概念设计系统实现。硬币分拣装置的概念设计表明,我们的功能表示方法可以使所提出的计算机辅助概念设计系统有效而准确地检索到所需物流处理功能的适当解原理。
Abstract Although there has been considerable computer-aided conceptual design research, most of the proposed approaches are domain specific and can merely achieve conceptual design of energy flows-processing systems. Therefore, this research is devoted to the development of a general (i.e., domain-independent) and knowledge-based methodology that can search in a wide multidisciplinary solution space for suitable solution principles for desired material-flow processing functions without designers' biases toward familiar solution principles. It first proposes an ontology-based approach for representing desired material-flow processing functions in a formal and unambiguous manner. Then a rule-based approach is proposed to represent the functional knowledge of a known solution principle in a general and flexible manner. Thereafter, a simulation-based retrieval approach is developed, which can search for suitable solution principles for desired material-flow processing functions. The proposed approaches have been implemented as a computer-aided conceptual design system for test. The conceptual design of a coin-sorting device demonstrates that our functional representation methodology can make the proposed computer-aided conceptual design system to effectively and precisely retrieve suitable solution principles for a desired material-flow processing function.
