public class ServiceNodeParam
extends NodeParam

Parameter container for service nodes in queueing networks.

This class stores configuration parameters for service nodes that process jobs according to externally defined service specifications. Service nodes can reference external files or configurations that define their behavior.

It is also the home of the per-station heterogeneous-server fields. These are ragged, node-type-conditional structures (server-type lists, compatibility matrices, per-type/per-class rates and processes) and therefore live in the nodeparam container rather than as flat NetworkStruct root fields. They are populated only for Queue stations that declare server types; for all other stations nservertypes stays 0 (homogeneous).

Since:

1.0

Fields

Modifier and Type	Field	Description
List<String>	fileName	List of file names or identifiers for external service definitions
Map<Integer,Map<Integer,MatrixCell>>	heteroproc	Heterogeneous service processes: heteroproc.get(serverTypeId).get(classId) -> PH matrices.
Map<Integer,Map<Integer,ProcessType>>	heteroprocid	Heterogeneous process types: heteroprocid.get(serverTypeId).get(classId) -> ProcessType.
Map<Integer,Map<Integer,Double>>	heterorates	Heterogeneous service rates: heterorates.get(serverTypeId).get(classId) -> rate.
HeteroSchedPolicy	heteroschedpolicy	Heterogeneous scheduling policy for this station.
int	nservertypes	Number of server types at this station; 0 indicates a homogeneous queue.
Matrix	servercompat	Server-class compatibility matrix: Matrix (nTypes x K), 1.0 if type t serves class r.
Matrix	serverspertype	Number of servers per server type: Matrix (nTypes x 1).
List<String>	servertypenames	Server type names; servertypenames.get(t) is the name of server type t.
