Application of dynamic manufacturing service provisioning mechanism to delivery commitment

The concept of "virtual fab" emphasizes manufacturing service provisioning. This paper designs a dynamic manufacturing service provisioning mechanism (DMSPM) for the creation, deployment, and execution of manufacturing services in a virtual fab (VF) environment with quality-of-service (QOS) guarantees. DMSPM exploits object-oriented technology to flexibly bind fab objects into services. To examine our ideas of DMSPM, the order commitment service (OCS) provided by foundry companies serves as a study case. A prototype is designed and implemented for realization of DMSPM in the OCS application by using the unified modeling language (UML) for object oriented modeling and a CASE tool for C++ code development. Results of experimentation with the prototype demonstrate both the ideas and the potential of DMSPM for application to virtual fab and e-business developments.
