Class BardSchweitzer

public class BardSchweitzer
extends AMVA

This class implements the Bard-Schweitzer approximate MVA algorithm [Sch79] for solving multiclass closed models. The approximation removes the class dependence of the queue lengths by substituting the queue length seen by a class with the total queue length, as described in the AMVA section of the JMVA chapter of the JMT user manual.
