This paper clarifies the class hierarchy among DEVS subclasses in terms of their expressiveness. We define the expressiveness of a given formalism as the scope of accepting event segments by the formalism. In this paper, we interpret that DEVS formalism can be nondeterministic as well as deterministic. Based on this interpretation, inclusion relationship between several different formalisms including Timed Automaton are shown. As a consequence, this paper contributes to DEVS standardization at a level of formalism. The classes clarify the power of DEVS and enable the development of powerful sub-languages that make it easier to work in particular domains - and to teach the basics of DEVS - as we do with a subclass, called FDDEVS.
