Create a Trajectory

This method initialises a trajectory object, which comprises a chain of activities that can be attached to a generator. See below for a complete list of available activities by category.

Usage

trajectory(name = "anonymous", verbose = FALSE)

Arguments

name

the name of the trajectory.

verbose

enable showing additional information.

Value

Returns an environment that represents the trajectory.

Available activities by category:

• Debugging: log_, stop_if

• Delays: timeout, timeout_from_attribute, timeout_from_global

• Arrival properties: set_attribute, set_global, set_prioritization

• Interaction with resources: select, seize, release, release_all, seize_selected, release_selected, release_selected_all, set_capacity, set_queue_size, set_capacity_selected, set_queue_size_selected

• Interaction with generators: activate, deactivate, set_trajectory, set_source

• Branching: branch, clone, synchronize

• Loops: rollback

• Batching: batch, separate

• Asynchronous programming: send, trap, untrap, wait

• Reneging: leave, handle_unfinished, renege_in, renege_if, renege_abort

Manage trajectories:

• Extract or Replace Parts of a Trajectory: Extract.trajectory

• Join Trajectories: join

• Number of Activities in a Trajectory: length.trajectory, get_n_activities

Examples

## create an empty trajectory
x <- trajectory("my trajectory")
x
#> trajectory: my trajectory, 0 activities

## add some activities by chaining them
x <- x %>%
  log_("here I am!") %>%
  timeout(5) %>%
  log_("leaving!")
x
#> trajectory: my trajectory, 3 activities
#> { Activity: Log          | message: here I am!, level: 0 }
#> { Activity: Timeout      | delay: 5 }
#> { Activity: Log          | message: leaving!, level: 0 }

## join trajectories
x <- join(x, x)

## extract and replace
x[c(3, 4)] <- x[2]
x
#> trajectory: my trajectory, 6 activities
#> { Activity: Log          | message: here I am!, level: 0 }
#> { Activity: Timeout      | delay: 5 }
#> { Activity: Timeout      | delay: 5 }
#> { Activity: Timeout      | delay: 5 }
#> { Activity: Timeout      | delay: 5 }
#> { Activity: Log          | message: leaving!, level: 0 }
