public class MMAP
extends MarkedMAP
implements Serializable

A Marked Markovian Arrival Process (MMAP) MMAP is a point process where arrivals are categorized into K different types (marks). Uses the standard MMAP representation: - D0: infinitesimal generator for transitions without arrivals - D1: rate matrix for transitions generating type-1 arrivals - D2: rate matrix for transitions generating type-2 arrivals - ... - Dk: rate matrix for transitions generating type-k arrivals This class is an alias for MarkedMAP, providing a consistent naming convention with other distribution classes in LINE.

Constructor Details

MMAP

public MMAP()

Default constructor creating an empty MMAP

MMAP

public MMAP(MatrixCell mmap)

Construct an MMAP from a MatrixCell containing {D0, D1, D2, ..., Dk}

Parameters:

mmap - MatrixCell where: - mmap.get(0) = D0 (transitions without arrivals) - mmap.get(k) = Dk (transitions generating type-k arrivals) for k >= 1

MMAP

public MMAP(Matrix D0,
 Matrix... Dk)

Construct an MMAP from D0 and variable number of Dk matrices

Parameters:

D0 - the infinitesimal generator for transitions without arrivals

Dk - variable number of matrices where Dk[i-1] represents transitions generating type-i arrivals

Method Details

getName

public String getName()

Returns the name of this distribution type.

Overrides:

getName in class Distribution

Returns:

"MMAP" to identify this as a Marked Markovian Arrival Process

getNumTypes

public int getNumTypes()

Get the number of arrival types (marks) in this MMAP

Returns:

the number of arrival types K

getTypeMatrix

public Matrix getTypeMatrix(int type)

Get the D_k matrix for arrival type k

Parameters:

type - the arrival type (1, 2, 3, ...)

Returns:

D_k matrix for the specified type, or null if out of range

fromMAPs

public static MMAP fromMAPs(Matrix D0,
 Matrix D1,
 Matrix D2)

Factory method to create a simple 2-type MMAP from two MAPs

Parameters:

D0 - the shared D0 matrix (transitions without arrivals)

D1 - rate matrix for type-1 arrivals

D2 - rate matrix for type-2 arrivals

Returns:

an MMAP with two arrival types

toString

public String toString()

Overrides:

toString in class Object
