public class Chow
extends AMVA

This class implements the Chow approximate MVA algorithm [Cho83] for solving multiclass closed models. The Chow approximation estimates the queue length seen by each class at every station from the queue lengths of the other classes, as described in the AMVA section of the JMVA chapter of the JMT user manual.
