Class ClassSwitchMatrix

java.lang.Object

jline.lang.ClassSwitchMatrix

public class ClassSwitchMatrix
extends Object

Matrix representation for job class switching probabilities in queueing networks.

ClassSwitchMatrix encapsulates the class switching behavior at nodes where jobs can change their class during service. This is essential for modeling systems where jobs undergo different processing stages or priority changes during their traversal through the network.

Key features:

• Stochastic matrix representation [classes x classes]
• Entry (i,j) represents probability of switching from class i to class j
• Row sums equal 1.0 for valid probability distributions
• Support for both deterministic and probabilistic class switching
• Integration with routing matrix computations

Common applications include modeling priority upgrades/downgrades, multi-stage service processes, and feedback systems with class-dependent routing.

Since:
