Abstract: A colored timed resource-oriented Petri net (CTROPN) was developed to model the cluster tools with revisiting in semiconductor manufacturing. The behaviors of process were discussed. From the aspects of quantitative and qualitative performance, the deadlock and throughput between one-hand robot and two-hands robot were analyzed. Then a sufficient condition for deadlock-free operation in the system and the corresponding control law were presented, the initial transient behavior, steady-state behavior and the final transient behavior could be investigated by using the single model.

Key words: cluster tool, modeling, revisiting
