中文摘要 | 產品原理結構模型通常被用來描述概念設計過程中的功能需求,對產品原理結構進行建模和優化是產品概念設計階段一個的重要任務。本文提出了基于功能和圖論的產品原理結構模型建模和優化方法。在這個方法中,我們依據功能分解和IDEF0方法來構建產品的原理結構模型,同時采用基于圖論的方法實現產品原理結構模型的表達和優化。在構造的圖中,邊代表產品結構中的組(部)件,頂點代表允許組(部)件間能量流通過的節點。通過對產品原理結構模型的優化,可以在早期設計階段發現并刪除產品中的冗余或導致功能失效的組(部)件。最后我們用一個例子驗證了該方法的有效性。 |
英文摘要 | Product principle structure model (PPSM) is generally used to represent functional requirement formally in conceptual design process. The construction and optimization of PPSM is an important task in product conceptual design phase. In this paper, a new function- and graph-based product principle structure modelling and optimization method for conceptual design is proposed. According to the principle of function decomposition, IDEF0 method is utilized to construct PPSM. After that, a graph-based approach is introduced to represent and optimize the PPSM. An edge represents a product component. The vertices depict joints that allow the flow of energy between components. Through the optimization of PPSM, components of a product that are redundant or cause of loss of functionality can be determined or deleted at early design stage. At last, a case study is presented to validate the proposed method. |
