dynamise: Add dynamic arrival times to nodes.

In jakobbossek/netgen: Network Generator for Combinatorial Graph Problems

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)
