Define a new resource in a simulation environment.
add_resource(.env, name, capacity = 1, queue_size = Inf, mon = TRUE,
preemptive = FALSE, preempt_order = c("fifo", "lifo"),
queue_size_strict = FALSE)the simulation environment.
the name of the resource.
the capacity of the server.
the size of the queue.
whether the simulator must monitor this resource or not.
whether arrivals in the server can be preempted or not based on seize priorities.
if the resource is preemptive and preemption occurs with
more than one arrival in the server, this parameter defines which arrival should
be preempted first. It must be fifo (First In First Out: older preemptible
tasks are preempted first) or lifo (Last In First Out: newer preemptible tasks
are preempted first).
if the resource is preemptive and preemption occurs,
this parameter controls whether the queue_size is a hard limit. By default,
preempted arrivals go to a dedicated queue, so that queue_size may be
exceeded. If this option is TRUE, preempted arrivals go to the standard
queue, and the maximum queue_size is guaranteed (rejection may occur).
Returns the simulation environment.
Convenience functions: schedule.
