本研究以裝配產品為對象,從並行工程的觀點建立結合裝配彈性設計與裝配程序規劃之裝配評估模式.裝配彈性設計的觀念在於產品設計時考慮裝配組件關係及系統資源特性,以提供具裝配彈性之產品再再設計建議,期能有效降低裝配設備之投資及裝配系統之運作成本.裝配程序規劃則在已知裝配產品模型及系統資源配置下, 於眾多可行裝配程序中選取最佳,提供裝配作業有效參考.本研究首先探討裝配產品與系統資源配置表示方法,接下來分別建立裝配彈性設計模組與裝配程序規劃模組. 裝配彈性設計模組包括裝配彈性設計準則,彈性分數評估及再設計診斷.裝配程序規劃模組包括了裝配程序表示,裝配程序評估準則及人工智慧搜尋法則.最後則建立結合裝配彈性設計與裝配程序規劃之並行工程架構,以 發展裝配評估模式,並以實例進行模式應用與驗證.

The purpose of this project is to develop an assembly evaluation model withconcurrent consideration of Design for Flexible Assembly(DFA) and AssemblySequence Planning(ASP). By applying the concepts of Design for Flexible assemblyin the early stage of the design process, flexible assembly products can be designedand thus increase the flexibility of the assembly systems. In addition, AssemblySequence Planning helps the selection of the best assembly sequence in which partsof subassemblies are put together in the mechanical assembly of a product that candrasticlly affect the affect the efficiency of the assembly process. Based on thestudies of DFA and ASP, the project takes a concurrent engineering approach by integratingthe DFA in the design stage with the ASP in the manufacturing stage in order todelelop an assembly evaluation model for assembly product design and process planning.The DFA module includes the functions of Flexibility Criteria, Flexibility Evaluationand Redesign Diagnosis. The ASP module includes the functions of Sequence Representation,Sequence Evaluation and AI Search Algorithm. Finally, an example is adopted forthe application and illustration of the concurrent assembly evaluation model being developed.
