wrap: Wrap a Simulation Environment

In simmer: Discrete-Event Simulation for R

Wrap a Simulation Environment

Description

This function extracts the monitored data from a simulation environment making it accessible through the same methods. Only useful if you want to parallelize heavy replicas (see the example below), because the C++ simulation backend is destroyed when the threads exit.

Usage

wrap(.env)

Arguments

.env	the simulation environment.

Value

Returns a simulation wrapper.

See Also

Methods for dealing with a simulation wrapper: get_mon_arrivals, get_mon_attributes, get_mon_resources, get_n_generated, get_capacity, get_queue_size, get_server_count, get_queue_count.

Examples

## Not run: 
library(parallel)

mm1 <- trajectory() %>%
  seize("server", 1) %>%
  timeout(function() rexp(1, 2)) %>%
  release("server", 1)

envs <- mclapply(1:4, function(i) {
  simmer("M/M/1 example") %>%
    add_resource("server", 1) %>%
    add_generator("customer", mm1, function() rexp(1, 1)) %>%
    run(100) %>%
    wrap()
})

## End(Not run)
