    From process to simulation - A transformation model approach
    (Enterprise modelling and information systems architectures, 2009) Kloos, Oliver; Nissen, Volker; Petsch, Mathias
    Process models are frequently used to visualise, analyse and control the flow of work in business processes. In principle, the information contained in process models could be used to simulate and optimise business processes with the help of simulation software. However, business process models are created for other purposes than simulation and, therefore, normally do not contain enough information to directly execute simulation studies using them. A process model first has to be converted to a simulation model which holds different information necessary for the simulation. In this paper, a transformation approach is presented which can be used to convert process models based on the event-driven process chain (EPC) notation to different simulation software systems.

    Service Modelling as a Basis for Simulation
    (Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 6, Nr. 2, 2011) Kloos, Oliver; Nissen, Volker; Petsch, Mathias; Schorcht, Hagen
    Process models are often created without regard to their possible later use in simulations. If a process model generated in this way is to be simulated, additional information must be gathered, the model adapted and transferred into an appropriate simulation environment. This process is complex, weakly structured and errorprone. Using practical example data from an outpatient clinic, this work introduces an approach for model transformation with which service process models can be transferred into a simulation environment in a structured way and supported by the system. The transformation concept focuses on process models generated without taking into consideration the requirements of future simulation. The concept prepares the process models for simulation and supports the transfer of the models into the appropriate simulation environment.
