This paper describes technical enhancements implemented in the second version of the Managed Readiness Simulator (MARS V2). These enhancements were required to address limitations in the technology and implementation of the initial prototype (MARS V1). The limitations related to data volume, data structures, algorithms and performance, which prevented larger and more complex scenarios from being simulated. Therefore, a range of potential approaches was identified, and a novel model architecture was devised that would address these limitations. The approach consisted of exploiting database technology during simulation execution which was termed a Simulation Runtime Database (SRDB). This allowed the simulation to use the database’s table data structures for runtime data storage and to invoke data processing algorithms through Structured Query Language commands. A feasibility study was conducted that proved that the SRDB could be implemented in the MARS simulation engine, Arena. This justified the implementation of the MARS V2 model using the SRDB approach. Testing of the completed MARS V2 model showed that it successfully addressed all four of the limitations identified in MARS V1. Ultimately, the SRDB approach provided a much more capable platform for large, complex simulation scenarios that will meet current and future client needs.
