摘要

近年來隨著全球競爭越來越激烈，產品生命週期也越來越短，縮短產品上市時間與提升品質無疑是企業提昇競爭力的一種方式。由於產品大部分的成本在設計階段就決定了，因此許多學者發展產品設計的法則或評估設計的工具，期望能夠在設計階段發現並解決問題。
然而大部分評估組裝設計之工具都將重點擺在減少零件數目以及產品組裝之效率評估，且常由設計者的觀點出發進行評估，對於評估產品設計是否易於被作業員正確組裝的相關研究卻很少。
本研究發展一套具互動式的虛擬實境組裝系統來評估產品設計，其包含四個模型：虛擬原型模型、互動控制模型、組裝限制模型、資料擷取模型。讓使用者在虛擬環境（Virtual Environment, VE）中對新產品進行組裝測試並紀錄其組裝作業之效率與正確率，將此資料回饋給設計者，輔助其找出易組裝錯誤或需要較久認知時間的零件，使設計者可以針對問題零件的修改，或者輔助決策者對於不同設計之方案之選擇。
本研究利用虛擬實境之技術對於產品設計做評估，可以大量減少製作實體原型的數量與製作所需花費的時間，達到節省成本與快速上市之目的；並且將資訊回饋給設計者，用以改善設計並產生出更穩健的產品，提升產品品質。

Recently, under the global competition, the products life cycle becomes much shorter. It is undoubtedly a way to enhance the competitiveness of an enterprise by reducing the time to market and improving the product quality. Due to the cost of product that is decided in the design stage mostly, some researchers address design rules or build evaluative tools that would be helpful to get some problems in product design stage.
There are many evaluative tools of assembly which are about how to reduce the number of components or enhance the efficiency of assembly operation to help design. Evaluating the design of assembly is usually generated by the view of designers, but there are few tools used to evaluate the error of operator cognition of assembly design.
This research develops a virtual assembly system which could evaluate the assembly design for human cognition. This system involves virtual prototyping model, interaction control model, assembly constraint model and data collect model. The user can complete the operation of virtual assembly in the virtual environment. Furthermore, this system will take down the efficiency and accuracy of those operations and then feed back the information to the designer for helping them to improve the defective components or choose the best design scheme.
This paper evaluates the assembly design of product with virtual reality technology which can decrease the cost and time by reducing the times of rebuilding the physical prototyping. It can also improve the quality of product by feeding back the information to the designer.
