Modeling And Simulation Of Net Centric System Of Systems Using Systems Modeling Language And Colored Petri-nets: A Demonstration Using The Global Earth Observation System Of Systems

摘要

architecture representation using SysML demonstrates an object-oriented approach of model development. This paper discusses issues related to architecture description, development, presentation, and integration for the chosen domain. This paper also highlights some of the differences between SysML, which is used to model a wide range of systems, and Unified Modeling Language (UML), which is primarily used to model information systems only. Finally, in order to synthesize an executable model from the static views developed using SysML, Colored Petri-nets (CP-nets) have been used. The executable model, constructed using CP nets, is used to validate the architecture against the static model. Overall, this research defines a methodology to model and simulate complex network centric system of systems in order to understand and simulate their behavior using a scenario based approach.
