Research on Time-scaled Process Diagram Driven System of System Project Schedule Management System

The logical relationship between the works of the system of system project is complex, and the process and schedule need to be adjusted frequently, which poses new challenge to the rapidity and accuracy of schedule adjustment. This paper analyzes the needs of system of system project schedule management including compatible work break structure(WBS) framework, multi-level WBS cooperative decomposition, multi-role schedule monitoring, time-scaled process diagram driven schedule update. The project process and schedule management system is developed, which includes 6 main function modules, time-scaled process diagram template module, time-scaled process diagram drawing module, time-scaled process diagram publishing module, time-scaled process diagram monitoring module, schedule list module, role management module. Creating schedule nodes in the time-scaled process diagram, drawing the relationship lines between nodes, adjusting the information of schedule nodes can drive the corresponding items in the schedule list synchronously updated. The operation is intuitive and effective, which improves the efficiency of schedule management. It’s an innovative practice for the system of system project schedule management method.
