Package jline.solvers.fluid

Class SolverFluid

  • All Implemented Interfaces:
    
public class SolverFluid
extends NetworkSolver

    SolverFluid is based on fluid and mean-field approximation methods. It provides fluid-based analysis for queueing networks, particularly useful for large-scale systems where discrete-event simulation would be computationally expensive.
