On the history of discrete event systems
WebA discrete event system is a dynamic system with discrete states the transitions of which are triggered by events. This provides a general framework for many man-made … WebComplex event processing. Event processing is a method of tracking and analyzing (processing) streams of information (data) about things that happen (events), [1] and deriving a conclusion from them. Complex event processing, or CEP, consists of a set of concepts and techniques developed in the early 1990s for processing real-time events …
