Estimation methods for delays in non-regenerative discrete-event systems

The various estimation methods for delays in non-regenerative discrete event systems were discussed. The sequences of delays, determined from the state transitions of the generalized semi-Markov processes (GSMP), were considered. The conditions on the building blocks of a GSMP and start-vector mechanism, under which the sequence of delays is an od-regenerative process and cycle sums have finite moments, were provided.
