public static java.lang.Object[] calculateDurationsUI(org.processmining.contexts.uitopia.UIPluginContext context,
                                                      org.processmining.models.graphbased.directed.petrinet.StochasticNet input_net)

Perform a duration analysis of the given net. Will open a panel, where the user can input additional parameters, such as which durations to check and whether the net should be discretized prior to the analysis.

Parameters:

context - The context of the prom instance.

input_net - The workflow net to be analyzed

Returns:

An array that contains the result of the analysis as a WorkflowNetAnalyzerResult, and the net that was analyzed. If the user enabled discretization, the returned net will be the result of this discretization.

Discretize the given net. Will take all inputs as parameters instead of via GUI.

Parameters:

context - The context of the prom instance.

input_net - The workflow net to be discretized

bucketInterval - How far apart the values in the discretized histogram will be. Smaller values lead to more accuracy.
