近年來,由於跨國企業合作機會的增加,企業間的競爭也越來越激烈,產品的生命週期也越來越短,再加上網際網路的普及,因此,傳統的設計流程受到很大的挑戰,本研究認為網路協同式設計是一個很好的概念,將有助於企業提升競爭力。為達到網路協同式設計的目的,需要在網路上執行程式,所以我們先比較了網路程式執行的優缺點,再以網路協同式熱交換器設計軟體的例子去驗證協同設計的可行性。針對熱交換器設計軟體人與人互動性不足的缺陷,本研究實作了互動式3D繪圖,使人與人的設計概念透過網路可以達到及時與互動式的分享,如果再配合視訊會議軟體,使設計者可以穿過空間的阻隔而即時的看到和分享討論彼此的概念,達到縮短設計周期的目的。 Recent years, transnational corporations are increasing, and competition between enterprises is also more and more intense. In addition, the life cycle of production is getting shorter, and Internet prevails among every respects. So, traditional mechanical design process is being challenged. Corporative design will be the best proposal for increasing the competitiveness of enterprise. Our research analyses characteristics of Internet programming, and applies to the case of “Plate Heat Exchanger Designer” and the case of “Interactive 3D Graphics” to verify the feasibility of Internet corporative design.
