Class CycleTimeAnalysis

java.lang.Object
jline.api.wfn.CycleTimeAnalysis
public class CycleTimeAnalysis extends Object
Exact single-case analysis of a sound Workflow Net, returned by WorkflowNet.getCycleTimeAnalysis().

The case duration of one case without contention is phase-type with initial vector alpha and subgenerator Q over the tangible transient states; 1 - sum(alpha) is the probability that the case completes in zero time. MATLAB twin: the struct returned by WorkflowNet.getCycleTimeAnalysis, whose firings and placeTime tables are the name/value arrays here.
