Method Details

isHomogeneous

public static Pair<Boolean,FJInfo> isHomogeneous(NetworkStruct sn)

Checks for a single fork-join pair with homogeneous parallel branches (port of MATLAB fj_is_homogeneous).

This is NOT a test for the presence of Fork/Join nodes: most fork-join models fail this predicate. It tests membership in the homogeneous class on which the FJ_codes tail approximation of Qiu, Perez and Harrison (IFIP Performance 2015) is defined: open classes only, a single fork-join pair (paired in sn.fj), no quorum, K Queue nodes routed Fork->Queue->Join, identical PH service representations across the K queues (within FineTol) for every class, and FCFS or PS scheduling.

Parameters:

sn - the network structure to test

Returns:

the verdict paired with the fork-join info; when the verdict is false the info carries the reason in FJInfo.errorMsg
