Business Process Simulation on Procedural Graphical Process Models

“…The simulation property of activity duration is discussed in the vast majority of reviewed publications, only seven publications do not mention this property. However, only about a quarter of the contributions comprises detailed explanations on how to specify activity durations (Oberweis 1996; Desel et al 1999;Erwin 2000, 2003;Chan et al 2009;Cimino and Vaglini 2014;Joschko 2014;Cartelli et al 2015Cartelli et al , 2016. The majority of approaches uses a fixed time value for the duration of activities, which in several cases is determined by assuming or calculating the mean value of the process execution time (e.g., Desel and Erwin 2003;Chan et al 2009;Holzmu ¨ller-Laue et al 2013).…”

“…Petri net Oberweis (1996), Desel et al (1999), Erwin (2000, 2003), Barjis (2007) BPMN models for simulation (Kanalici et al 2009;Kloos et al 2010Kloos et al , 2011Vasilecas et al 2013;Kloos 2014;Lu ¨bbecke et al 2015) and one further publication mentioning to use data from simulation logs for this purpose (Cimino and Vaglini 2014).…”

“…Approaches starting from a Petri net Petri net-based approaches are unsurprisingly among the earliest proposals to BPS (e.g., Oberweis 1996). The Petri net-based approaches in the final sample represent a business process as Petri net and, without further transformation, simulate by generating runs of the Petri net (Oberweis 1996;Desel et al 1999;Erwin 2000, 2003). Hence all Petri net-based approaches in the review sample fall into the category of 'direct simulation approaches'.…”

“…In Desel et al (1999) and Erwin (2000, 2003), an approach to BPS, called VIP Project (Desel and Erwin 2000, p. 237), is suggested. Starting from a Place/Transition net, a class of Petri nets representing a business process, a representative set of concurrent runs of the net is selected with the aim of including standard cases and regular exceptions.…”

“…A business process simulator called VIPtool is developed and applied within the VIP Project (Desel et al 1999;Erwin 2000, 2003). The software tool allows to simulate business processes by generating concurrent runs of the Place/Transition net representing a business process (Desel and Erwin 2003, pp.…”
