Stochastic BPMN and Their Conformance

Partially Ordered Earth Movers' Stochastic (POEMS) Conformance Checking for BPMN

What is it?

The first stochastic conformance checking method for BPMN is implemented as a package in ProM.

• Stochastic-aware conformance checking.
• Formal definition and specification extension of the BPMN standard with stochastic perspective. See SBPMN ProM GitHub package repo.

Usage

This method has two main inputs: a stochastic BPMN and an event log. Acquiring the event log (XES) is a standard procedure in the Process Mining community. To learn more about the format of the stochastic BPMN and how to acquire it, please refer to the SBPMN ProM GitHub package repo.

In ProM

Java

Very basic usage with default configuration.

BpmnPoemsConformanceChecking poems = BPMNStochasticConformanceChecking.poems();
POEMSConformanceCheckingResult result = poems.calculateConformance(sBpmnDiagram, xlog);
Double conformanceValue = result.conformanceValue(); // A value between 0 and 1

Advanced Usage

For more advanced usage, check out the BpmnPoemsConformanceChecking interface and the getInstance factory methods provided there.

Since this approach is based on sampling behavior from the Stochastic BPMN model, you can use this class to configure the sampling procedure and acquire samples with the desired properties.
