Survey of Simulation Composability of Complex Systems

Simulation composability is more attractive in the development and integration of complex system simulations. The basic concepts of simulation composablity were introduced, followed by the analysis of the complexity and the levels of simulation composability. The current approaches to achieve different levels of simulation composability were introduced and compared according to the hierarchy of simulation composability, such as common model repository approach, interoperability protocol approach; composition validity-based semantic approach, DEVS based formal approach and MDA based approach. The multi-level composability and MDA based approach to multi-level composability were studied according to the survey of current research on simulation composability.
