STD (State Transition Diagram) is used to analyze the system from "state" and "transition" perspective. But, the existent STD can't describe concepts such as states of two or more personnel, synchronization between personnel and time advance which are necessary to model the collaborative systems. This paper proposes Timed STDs with the three concepts, and models the collaborative systems with this diagram. And the authors developed the simulator to show an animation of transition and synchronization and to analyze the performance parameters such as utilization.
