public class NodeParam
extends Object
implements Serializable

Base class for node parameters in queueing network models.

NodeParam stores job class-dependent parameters that control the behavior of network nodes (stations). This includes routing weights, outbound links, memory-dependent parameters, and other node-specific configuration data.

The parameters are organized by job class, allowing different classes to have different behaviors at the same node. This is essential for multi-class queueing networks where job classes may have different service requirements, routing patterns, or other characteristics.

Subclasses extend this base functionality for specific node types such as caches, forks, joins, and service stations.

Field Details

weights

public Map<JobClass,Matrix> weights

Routing weights by job class - controls probabilistic routing decisions

outlinks

public Map<JobClass,Matrix> outlinks

Outbound link specifications by job class - defines outgoing connections

weightedOutlinks

public Map<JobClass,Matrix> weightedOutlinks

Weighted round-robin cycle by job class: the outlink node indices with each destination repeated by its integer weight. The WRROBIN pointer holds a POSITION (1..len) in this cycle rather than a node index, so repeated destinations are visited in the correct proportion.

d

public Map<JobClass,Integer> d

SQ(d): d, the number of sampled destinations, per job class (mirrors the MATLAB nodeparam.d field).

patience

public Map<JobClass,Distribution> patience

Patience distributions by job class for customer abandonment modeling

sdr

public Map<JobClass,StateDepRouting> sdr

Krzesinski (1987) state-dependent routing structure, in node indices, as declared on the entry center. The station-indexed twin lives on NetworkStruct.sdr. See jline.lang.StateDepRouting.

Constructor Details

NodeParam

public NodeParam()

Constructs an empty NodeParam with initialized parameter maps.

All parameter maps are initialized as empty HashMaps, ready to store job class-specific configuration data.

Method Details

isEmpty

public boolean isEmpty()

Checks if this NodeParam contains no configuration data.

Returns:

true if all parameter maps are null or empty, false otherwise
