Interoperabilidade entre simuladores construtivos e virtuais táticos: uma abordagem para extensão do simulation object model do simulador MASA SWORD

Abstract

Differences in the desired fidelity and abstraction for the development of simulation systems provide models with distinct purposes and modelling, i.e. resolution discrepancies. In the distributed simulation field, interoperability is a feature that enables the linkage of different systems in an integrated exercise. The development of this linkage is a non-trivial task and presents many challenges. In this context, the MASA SWORD, which is an aggrega- ted constructive simulator with high-level abstraction and mainly used to strategic training, has a HLA plug-in to enable the simulator to participate in a HLA federation as a federate. However, this HLA plug-in was developed based on your constructive model that abstracts many details and works with a small set of information. This characteristic makes it unable for integration with simulator that require a higher information level. This work presents a solution for this problem, called SWAF (SWORD Auxiliary Federate), which extends the SOM (Simulation Object Model) - information set with which the simulator works through its HLA interface - of the constructive simulator to interoperate with a virtual tactical simu- lator in a HLA federation. The SWAF allows the publication of additional information about MASA SWORD through an auxiliary federate that works in parallel with the original HLA plug-in of SWORD. A discussion about interoperability is also presented and used to define requirements specification that are modeled in a new federation agreement. The work uses an indirect SOM extension methodology to overcome COTS (Commercial off-the-shelf) bar- rier and kept intact the original HLA interface of SWORD simulator. To validate the work, a study case was developed with Simulador Virtual Tático de Reconhecimento, Escolha e Ocupação de Posição (SVTat REOP).
