Abstract: A modification of Petri nets is suggested which is capable of detecting event time arrangement (ETA) at the pace of observation arrivals. An algebraic representation of ETA descriptions has been developed which allows dynamic recognition algorithms to be built by a computer. The procedure could be used in automatic control systems for complex technological objects monitored by remote sensing.
