Abstract: The command and control system can be reconfigurable on demand under multi-task conditions, based on the idea of servitization and using workflow engine-driven technical architecture, a workflow modeling method for command and control software integration is proposed. Based on UML extension mechanism, the time modeling, information modeling, flexible modeling and plug-in description information modeling of command and control flow are realized. To solve problems of insufficient time, information and flexibility of command and control process, meet the requirements of dynamic matching of command and control software plug-in, and provide support for flexible integration of command and control software, the visual construction of workflow model for command and control software is realized based on UML modeling tool. The feasibility of the method is verified by an example.
