【摘要】：在以買方為主導的全球化市場經濟環(huán)境中，客戶的需求時時變化，產品的交貨期越來越短，質量要求不斷提高。傳統(tǒng)的產品開發(fā)模式已難以適應多變的市場需求。而整車企業(yè)作為典型的離散型制造企業(yè)，擁有復雜的產品結構，繁多的產品種類和數(shù)量，會造成整車企業(yè)產品開發(fā)周期長，無法快速響應市場，同時也加大了管理的難度。 為應對市場環(huán)境變化與信息技術發(fā)展帶來的挑戰(zhàn)，整車企業(yè)迫切需要結合企業(yè)實際建立一種集成環(huán)境下新的產品協(xié)同開發(fā)模式，來有效管理企業(yè)內復雜而繁多的產品數(shù)據(jù)、業(yè)務流程、信息流，實現(xiàn)高效的產品協(xié)同開發(fā)。為實現(xiàn)產品的多樣化、產品成本有效控制以及產品質量的保證，需要在產品開發(fā)過程中最大限度地降低設計變更，有效改善因設計變更導致的開發(fā)時間延長，成本提高等問題。 本文從整車產品開發(fā)流程、整車產品開發(fā)管理體系、信息化環(huán)境下跨系統(tǒng)信息交互以及基于PDM系統(tǒng)產品協(xié)同開發(fā)四方面內容出發(fā)，對信息化環(huán)境下整車企業(yè)協(xié)同產品開發(fā)過程進行了深入分析。支撐整車產品開發(fā)的信息化過程中主要存在產品開發(fā)周期長、成本高，由信息系統(tǒng)集成度低導致的信息數(shù)據(jù)延遲、失真、設計變更率高等問題。 在對企業(yè)面向服務架構應用集成環(huán)境和整車產品協(xié)同開發(fā)業(yè)務流程研究的基礎上，本文提出了以基于SOA架構的信息交互共享、產品協(xié)同開發(fā)機制和產品協(xié)同安全策略三個內容為核心的整車企業(yè)集成環(huán)境下產品協(xié)同開發(fā)模式�；诩森h(huán)境下的信息交互共享實現(xiàn)方式，分別從企業(yè)內部與外部構建了產品開發(fā)協(xié)同機制。針對產品協(xié)同開發(fā)過程中存在的安全沖突，，建立了集成環(huán)境下知識安全模型，并提出相應的協(xié)同安全策略。 最后本文將以上理論成果應用于整車企業(yè)的實際產品開發(fā)過程中，以A企業(yè)基于SOA集成化系統(tǒng)的構建與實施作為實例。根據(jù)A企業(yè)整車產品開發(fā)信息化環(huán)境現(xiàn)狀，闡述了集成平臺的構建與實施步驟。實際應用表明：基于SOA的產品協(xié)同開發(fā)模式能有效降低設計變更率、及時發(fā)現(xiàn)設計問題，從而降低開發(fā)成本并提高產品質量。
[Abstract]:In the global market economy environment dominated by buyers, customer demand is constantly changing, the delivery time of products is shorter and shorter, and the quality requirements are constantly improved. The traditional product development model has been difficult to adapt to the changing market demand. As a typical discrete manufacturing enterprise, the whole vehicle enterprise has complex product structure, various product types and quantity, which will result in a long product development cycle, unable to respond to the market quickly, and increase the difficulty of management. In order to meet the challenges brought by the change of market environment and the development of information technology, it is urgent for the whole vehicle enterprise to establish a new product cooperative development model under the integrated environment to effectively manage the complex and various product data in the enterprise. Business process, information flow, achieve efficient product collaborative development. In order to realize the diversification of products, the effective control of product cost and the guarantee of product quality, it is necessary to minimize the design changes in the process of product development, and effectively improve the development time and cost increase caused by the design changes. This paper starts from four aspects: the whole vehicle product development process, the whole vehicle product development management system, the cross-system information exchange under the information environment and the product cooperation development based on the PDM system. In this paper, the collaborative product development process of the whole vehicle enterprise under the information environment is deeply analyzed. In the process of supporting the product development of the whole vehicle, there are many problems, such as long product development cycle, high cost, low information system integration, information data delay, distortion, high design change rate and so on. Based on the research on the application integration environment of enterprise service-oriented architecture and the business process of collaborative development of vehicle products, this paper proposes an interactive sharing of information based on SOA architecture. The product cooperative development model under the integrated environment of vehicle enterprise is the core of product cooperative development mechanism and product cooperative security strategy. Based on the implementation of information interaction and sharing in the integrated environment, the product development cooperation mechanism is constructed from the internal and external aspects of the enterprise. In view of the security conflicts in the process of product collaborative development, the knowledge security model in the integrated environment is established, and the corresponding cooperative security strategy is proposed. Finally, this paper applies the above theoretical results to the actual product development process of the whole vehicle enterprise, taking the construction and implementation of the integrated system based on SOA in the A enterprise as an example. According to the present situation of the information environment of vehicle product development in Enterprise A, the construction and implementation steps of the integrated platform are expounded. The practical application shows that the collaborative product development model based on SOA can effectively reduce the design change rate, discover the design problems in time, and thus reduce the development cost and improve the product quality.
