We build a hybrid discrete-continuous simulation model of the manufacturing enterprise system. This model consists of an overall system dynamics model of the manufacturing enterprise and connected to it are a number of discrete event simulations for selected operational and tactical functions. System dynamics modeling best fits the macroscopic nature of(More)
Multi-resolution modeling (MRM) includes many different approaches. It is very well known by the Distributed Simulation community that the High Level Architecture (HLA) is an architecture designed to facilitate interoperability and software reuse. Therefore, the unit of MRM is usually the federate. Multi-resolution representation of entities consists in(More)
This paper presents preliminary analysis of the Panama Canal Expansion from the viewpoint of salinity in the Gatun Lake and the utilization of neural networks. This analysis utilized simulation modeling and artificial intelligence. We have built several discrete and system dynamics simulation models of the current Panama Canal operations and the future(More)
Interoperation of simulation models is an important issue due to high level requirements of reusability, scalability, and eventually training effect. Achieving Live, Virtual and Constructive (LVC) simulation interoperability is a main goal and a major challenge for M&S community. High interoperability quality in LVC simulation environment is a(More)
