NewInput.MCCN {queueing}

Define the inputs of a MultiClass Closed Network

Description

Define the inputs of a MultiClass Closed Network

Usage

NewInput.MCCN(
  classes, vNumber, vThink, nodes, vType, vVisit, vService, method=1, tol=0.01
)

Arguments

classes

The number of classes

vNumber

A vector with the number of customers of each class

vThink

A vector with the think time of each class

nodes

The number of nodes in the network

vType

A vector with the type of node: "Q" for queueing nodes or "D" for delay nodes

vVisit

A matrix[i, j]. The rows represents the different visit count for each class i to each node j

vService

A matrix[i, j]. The rows represents the different service time for each class i in each node j

method

If method is 0, the exact MVA algorith is used. If method is 1, the Bard-Schweitzer approximation algorithm is used

tol

If the parameter method is 1, this is the tolerance parameter of the algorithm
