Soa-Standard-Conform Modeling as a High-Level-Standard for Discrete Simulation

Summary form only given. Simulation models, created with leading simulation tools can not be exchanged between the systems, because there is no universal standard for discrete simulation. This results in very high investments and maintenance costs for simulation studies and some additional problems with flexibility in large simulations. A new approach seems now possible by using service oriented architectures (SOA). The integration of SOA-interfaces in simulation systems connects them to the IT-infrastructure of ERP-systems, business process modeling systems and web-services. This option allows a dual use of the generated models for simulation and real control software. The SOA standards BPMN and BPEE are also capable for simulation modelling and are accepted by all major IT companies. The poster presents examples, how BPMN models can be converted to single simulation programs, which eliminates the critical performance issues of SOA-Web service interfaces. In conclusion, the SOA technology can open a new chapter in discrete simulation modelling
