Monotone Structure in Discrete-Event Systems

A discrete event system (DES) is an abstraction of many engineering and service systems characterized by event-driven dynamics. Examples include computer systems, communication networks, airports and highways. The evolution of DES is governed by events, typically occurring at random time periods. Developing new mathematical tools to study discrete event operations research, this study discusses the two lines of investigation in DES research that have emerged: logical/qualitative issues and temporal/quantitative analysis.
