dynamise

Add dynamic arrival times to nodes.

Description

Some variants of the Vehicle Routing Problem (VRP) consider static as well as dynamic customers (nodes). This function takes a Network and dynamises it, i. e., it adds dynamic arrival times to the customers via a Poisson process.

Usage

dynamise(x, n.dynamic = NULL, dyn.customers.ratio = NULL,
  arrival.limit)

Arguments

`x`	[`Network`] Network.
`n.dynamic`	[integer(1) \| NULL] Number of nodes, which should become dynamic. Ignored if `dyn.customers.ratio` is not `NULL`.
`dyn.customers.ratio`	[numeric(1) \| NULL] Ratio of dynamic nodes. If this is set to a numeric value in (0, 1), the parameter `n.dynamic` is ignored.
`arrival.limit`	[numeric(1)] Maximal arrival time.

Value

[Network] Modified network (now has an additional list element 'arrival.times') and the ratio of dynamic customers as an attribute.

Examples

x = generateClusteredNetwork(n.points = 100L, n.cluster = 4L, upper = 100, n.depots = 2L)
x = dynamise(x, dyn.customers.ratio = 0.3, arrival.limit = 400)
print(x)
