DEVS

DEVS abbreviating Discrete Event System Specification is a modular and hierarchical formalism for modeling and analyzing general systems that can be discrete event systems which might be described by state transition tables, and continuous state systems which might be described by differential equations, and hybrid continuous state and discrete event systems. DEVS is a timed event system.

One of known SP-DEVS's limitation is a phenomenon that "once an SP-DEVS model becomes passive, it never returns to become active (OPNA)". 3(b) are not SP-DEVS because the total state associated with "idle" (I), is passive but it moves to an active state, "toast" (T) whose toating time is 20 seconds or 40 ...
