Given a coupled DEVS model, simulation algorithms are methods to generate the model's legal behaviors, which are a set of trajectories not to reach illegal states. (see behavior of a Coupled DEVS model.) [Zeigler84] originally introduced the algorithms that handle time variables related to lifespan
and
where
is equivalently computed as
, apparently
Based on these relationships, the algorithms to simulate the behavior of a given Coupled DEVS are written as follows.
