Flexible application framework for manufacturing execution systems

For the complexity of constructing Manufacturing Execution Systems (MES), a flexible application framework was proposed, based on multi-layer application service architecture. Some advanced technologies, such as object-oriented analysis for business process, event-driven mechanism with business rules and business engineering analysis, were used to achieve reconfigurable organization, scalable business processes and customizable business rules, which increased the development flexibility of MES software systems. At last, one instance was analyzed and realized by using the framework.
