On d-inversion in interruptive timed discrete-event systems

摘要

The authors consider the problem of extracting event lifetimes from partial observations of an interruptive timed discrete-event system. The extraction of the lifetime of an occurring event is based on observations of all previous transitions and d-subsequent transitions. We refer to this notion as d-inversion. We give necessary and sufficient structural conditions for an event to be d-invertible in a given system
