Structural Control Policies (SCP's) are real-time FMS operating policies that guarantee deadlock free operation. SCP's must be correct and scalable. A correct SCP guarantees deadlock free operation while a scalable (polynomial) SCP remains computationally tractable as FMS size increases. The NP-completeness of state safety (is there a sequence of state transitions leading to the empty state?) i...
