    Nowadays, industries are implementing heterogeneous systems from different domains, backgrounds, and operating systems. Manufacturing systems are becoming more and more complex, which forces engineers to manage the complexity in several aspects. Technical complexities bring interoperability, risk management, and hazards issues that must be taken into consideration, from the business model design to the technical implementation. To solve the complexities and the incompatibilities between heterogeneous components, several distributed and cosimulation standards and tools can be used for data exchange and interconnection. High-level architecture (HLA) and functional mockup interface (FMI) are the main international standards used for distributed and cosimulation. HLA is mainly used in academic and defense domains while FMI is mostly used in industry. In this article, we propose an HLA/FMI implementation with a connection to an external business process-modeling tool called Papyrus. Papyrus is configured as a master federate that orchestrates the subsimulations based on the above standards. The developed framework is integrated with external heterogeneous components through an FMI interface. This framework is developed with the aim of bringing interoperability to a system used in a power generation compan

    Conference of Symposium on Theory of Modeling and Simulation - DEVS Integrative M and S Symposium, DEVS 2013, Part of the 2013 Spring Simulation Multiconference, SpringSim 2013 ; Conference Date: 7 April 2013 Through 10 April 2013; Conference Code:96780International audienceModel-based engineering is becoming a de facto paradigm for designing complex systems and software. By being executable, models are easier to understand, as well as systems they abstract. UML is the most natural choice for modeling. fUML is an executable subset of UML with precise operational semantics. From causal relations defined in a model, fUML semantics only constructs partial execution orders. When considering fUML in a simulation process, this limitation is possibly an issue for engineers to observe various execution schemes and to have a representative execution of a system model. Usually simulation frameworks control the execution of an application thanks to a dedicated entity. This latter is responsible for the construction of the execution order conforming to the semantics of a specific Model of Computation (MoC). Furthermore it can be used to reflect extra-functional aspects like time. In order to overcome these limitations, this paper proposes principles to use fUML as a simulation environment. We propose to extract the execution control policy from a fUML model and to delegate it to a specific simulation library defining MoCs as fUML models. This library is responsible for controlling the execution and simulating extra-functional aspects. This approach provides the required flexibility and openness needed to support various applications domains. The solution is evaluated on a simple, but representative example
