Configurable Enterprise:A New Trend in Manufacturing Enterprise Evolution

Along with the popularity of enterprise applications,the management reform of manufacturing enterprise(ME) relies on the business process reengineering is gradually invalid.Reviewing and comparison the former structure of different enter- prise such as extend enterprise,virtual enterprise etc.from the perspective of link,unit,and focus.Through comparison the evo- lution of ME structure the configurable enterprise(CE)was put forward which based on the information and communication tech- nology providing a new mechanism for the elements configuration and the resources allocation.Based on the reference model of en- terprise business architecture,the framework of CE was raised,which includes enterprise business architecture,business model and component.Then modeling the dynamics of CE,the mechanism of key success factors interactions was analyzed and verified the key factors that de decided the evolution of CE which could forecast the development trend of manufacturing enterprise.     

Configurable Enterprise: A New Trend in Manufacturing Enterprise Evolution

Along with the popularity of enterprise applications, the management reform of manufacturing enterprise (ME) relies on the business process reengineering is gradually invalid. Reviewing and comparison the former structure of different enterprise such as extend enterprise, virtual enterprise etc. from the perspective of link, unit, and focus. Through comparison the evolution of ME structure the configurable enterprise (CE) was put forward which based on the information and communication technology providing a new mechanism for the elements configuration and the resources allocation. Based on the reference model of enterprise business architecture, the framework of CE was raised, which includes enterprise business architecture, business model and component. Then modeling the dynamics of CE, the mechanism of key success factors interactions was analyzed and verified the key factors that de decided the evolution of CE which could forecast the development trend of manufacturing enterprise.
