Abstract: The author shows that timed nets under the earliest firing rule can be transformed equivalently to Petri nets working under the maximum firing strategy. Additionally, two sufficient conditions are given for live Petri nets to remain live under any timing.
Keywords: timed net; liveness; earliest firing rule.
