MTI’s Modeling and Simulation (M&S) capability is well aligned with the NASA KLXS III mission. MTI has access to numerous models and simulations that can be used for Undersea, Ground Based, Airborne (including high altitude A/C), Space and Surface Vessels. Many of these models and simulations are available for export or in the public domain, such as Qualnet’s “Modeler” used to evaluate Communication Networks of various sizes in benign and disturbed environments. Electromagnetic Propagation Models ranging from ELF (45 Hertz) to Optical ranges in the frequency spectrum are also available and many more.
These models and simulations can be used to evaluate performance of C4ISR systems in the benign and disturbed environments (jamming for example). MTI also has access to software tools that can be used to integrate and interoperate disparate models and simulations. This is important for large-scale simulations. MTI’s personnel have experience in applying Models and Simulations for the following applications within the acquisition cycle:
- Conceptual Analysis
- Steer Design and Development of Systems, Subsystems, and Platforms
- Augment Test and Evaluation (both DT and OT)
- Training Applications
- Mission/Operations Analysis
Working within the acquisition process requires models and simulations that range from engineering, platform, and mission to force-on-force levels within the hierarchy of modeling and simulation.
Within the training domain, MTI’s personnel have been engaged in the use of LIVE, Virtual and Constructive (LVC) processes. LVC has potential for other parts of the acquisition process besides training.
Integrating and networking models, simulations, associated data bases, and LVC requires scalability in terms of entity throughput and entity interactions in real time. Scalability becomes very important and MTI has a clear understanding of this issue. Essentially a scalable system is one that can handle increased workload by adding more computing hardware resources in a proportional manner. Scalability means not just the ability to operate, but to operate with consistent performance, over the given range of configurations and scales. A peer-to-peer architecture uses a network model in which each node has the same capabilities so that any node can initiate a direct communication session with another node. A peer-to-peer architecture is inherently scalable because there is no central process or facility that can become a bottleneck. Of course, the Internet uses a peer to peer approach and scales exceedingly well.
