Research on Workflow Rule Engine Based on Process Manager Screening

According to the requirements of dynamic allocation of human node managers in business conditions, a workflow manager filtering rule engine is designed and implemented, which extends the human variable interface provided by the existing workflow engine, and dynamically sets the manager set by executing the rules defined in the run-time. The engine analyzes the basic elements of the filter rules of process managers, defines the object model of the filter rules and the algorithm logic of rule analysis, and provides the visual editing and design interface of the rules, so as to reduce the operation difficulty of operators, and finally achieve the purpose of fast and flexible distribution of managers. The rule engine has been applied in many enterprises with the open source activiti workflow engine and achieved good results.
