工作流元模型改进研究

Improvement of Workflow Metamodel

针对目前政府采购系统复杂的业务需求,为了对新工作流引擎的设计提供一个参考模型,文中采用工作流技术在元模型的功能方面进行了一定的扩展改进,为新的工作流引擎设计提供了清晰的思路,保证开发出的工作流引擎应用更灵活,功能更完善.改进后的元模型在政府采购系统中的应用,能够很好的适应目前复杂业务的需求,更方便的解决实际问题.

In order to meet the business requirements of the government procurement system and provide a reference for the design of a new workflow engine, an improvement was made in the function of the metamodel by using workflow technology, which ensures flexible applications and perfect function to the new workflow engine. The application of the improved metamode in the government procurement system shows that it can meet the business requirements better and solve practical problems more conveniently.
