The Design of Flexible Workflow in Scientific Research Management System

摘要

In scientific research management projects, if the process model changes, without a workflow technology, the codes need to be modified and the workload of modification will increase significantly. After introducing a flexible workflow technology, what can be done is to directly define the new process model. This paper mainly introduces ECA rules on the basis of workflow meta-model to design a flexible workflow: the ECA rules will express execution logics of the basic workflow, and the basic elements of the process model in the approval process of scientific research projects will be represented by ECA. The design of the flexible workflow in scientific research management system will include flexible workflow engine and the process approval platform for scientific research project management with ECA rule analysis. The flexible workflow implemented in this paper can better guide the workflow engine to adapt to the current environment, and decide the different execution process according to the specific process instance contexts. The method proposed in this paper better supports the needs of scientific research project management.
