    Architecture blueprint for a business process simulation engine

    Simulation of business process models allows for drawing conclusions on the performance and costs of business processes before they are implemented or changed. Requirements for a business process simulation engine are specific to a concrete use case and a dedicated business domain. In this paper, we focus on the simulation of clinical pathways in a hospital. We elaborate on the requirements imposed by this use case in detail and propose an architecture blueprint for a simulation engine. It is based on annotated BPMN process models and uses timed and colored Petri nets as the underlying formalism.

    Comparing Pre Commit Reviews and Post Commit Reviews Using Process Simulation
    (Software Engineering 2017, 2017) Baum, Tobias; Kortum, Fabian; Schneider, Kurt; Brack, Arthur; Schauder, Jens
    Previous studies found that two variations of change-based code review are used in in- dustry: Pre commit review and post commit review. Which one is better in a given situation is not obvious. So we asked: Are there practically relevant performance differences between pre and post commit reviews? How are these differences influenced by contextual factors? To assess these ques- tions, we designed and validated a parametric discrete event simulation model of certain agile devel- opment processes. Our analysis indicates that the best choice does depend on the context, but also that there are many situations with no practically relevant difference between both choices. We iden- tified the main influencing factors and underlying effects and condensed our findings into heuristic rules.
