摘要
由於全球化經濟所導致的專業分工，使得產品開發之經營團隊因地域性的區隔而分散於世界各地，為了及時反應不斷快速變化之顧客需求以保有企業自我之競爭優勢與利基，有效整合產品開發資訊與時程之控管為相當受到重視的關鍵因素。本研究在於提供有效之協同設計資訊架構之目的與考量下，採取強調能自動化輔助解決協同活動行為問題之多代理人系統，同時發展一創新的三維產品模型資料格式XC3D (XML-Based Collaborative 3D Product Model)，以彌補現有資料格式所含資訊不足之缺憾，並在多代理人的資訊架構下，以XC3D格作式為重要的資訊核心，除了藉由搭配嵌有不同設計特徵篩選機制的XSLT樣版來支援多層次產品模型的三維產品技術之外，更結合網格變形所需之資訊技術，讓使用者在沒有CAD系統的支援與減少網路傳輸資料量的前提下，提供以網格重新轉換而不重新網格化之設計特徵修改機制；在相同前提下，更是發展出以組裝限制關係為基之自動化設計變更傳遞，讓設計特徵修改的同時可經由組裝關係自動偵測相關受影響之零件。因此，藉由XC3D所支援之三維產品資訊技術，不但能達到產品設計資訊內容分級，提昇資訊交換之效用外，更能讓使用者能進行線上客製化審視與設計變更檢視之功效。此外，利用代理人間協同合作之特性，以非同步回溯演算法實作多代理人間透過訊息之交換與溝通，自動化解決協同設計活動中最為繁瑣之產品規格確定動作，以減少以往需要人為進行的參數協調動作，提升協同設計之效率。最後則由代理人產品開發系統雛型之實作驗證資訊架構與資料結構之可行性。
