Add a Generator

Attach a new source of arrivals to a trajectory from a generator function.

Usage

add_generator(.env, name_prefix, trajectory, distribution, mon = 1,
  priority = 0, preemptible = priority, restart = FALSE)

.env: the simulation environment.
name_prefix: the name prefix of the generated arrivals. If several names are provided, several generators will be defined with the same parameters.
trajectory: the trajectory that the generated arrivals will follow (see trajectory).
distribution: a function modelling the interarrival times (returning a negative value or a missing value stops the generator).
mon: whether the simulator must monitor the generated arrivals or not (0 = no monitoring, 1 = simple arrival monitoring, 2 = level 1 + arrival attribute monitoring)
priority: the priority of each arrival (a higher integer equals higher priority; defaults to the minimum priority, which is 0).
preemptible: if a seize occurs in a preemptive resource, this parameter establishes the minimum incoming priority that can preempt these arrivals (an arrival with a priority greater than preemptible gains the resource). In any case, preemptible must be equal or greater than priority, and thus only higher priority arrivals can trigger preemption.
restart: whether the activity must be restarted after being preempted.

Returns the simulation environment.
