Abstract

Manufacturing systems can be thought as production networks nodes whose relations have a strong impact on design and analysis of each system. Commercial simulators are already adopted to analyse complex networked systems, but the development of a monolithic model can be too complex or infeasible when a detailed description of the nodes is not available outside the ‘owner’ of the node. Then the problem can be decomposed modelling complex systems with various simulators that interoperate in a synchronized manner. Herein, the integration of simulators is addressed by taking as a reference the High Level Architecture (HLA). This paper proposes modifications to Commercial-off-the-shelf Simulation Package Interoperability Product Development Group protocols and to use patterns of how HLA can be effectively adopted to support Commercial Simulation Package interoperability: a new solution for the synchronous entity passing problem and modifications to the Entity Transfer Specification are presented. The resulting infrastructure is validated and tested over an industrial case.
