SiMSA   Simulation Modeling for Safe AI (SiMSA)

Central to SiMSA is RTSync's Automatic Scenario Construction/Selection (ASC) technology that creates a capability to model and simulate complex System of Systems (SoS) by composing them from component system models in various combinations and configurations. Sponsored by the Missile Defense Agency (MDA), ASC aggregates models of elements, environments, threats, and defenses from repositories into simulation executable form. We are currently demonstrating ASC and SiMSA capabilities with advanced synthetic aperture radar deep learning applications sponsored by the Air Force Research Lab (AFRL).

ASC   Automatic Scenario Construction/Composition (ASC) for Smart Testing and Evaluation

The ASC supports the automatic aggregation of Ballistic Missile Defense System (BMDS) elements, environments, threats, and representations from a repository into executable form and is capable of evolving with future adversary threats, the BMDS architecture, mission evolution (e.g., Integrated Air and Missile Defense (IAMD)), stakeholder needs and BMDS Modeling & Simulation (M&S) enterprise activities.

CAMLI   Model Level Integrated Simulation Architecture for Collaborative Development (CAMLI)

CAMLI provides Advanced Modeling and Simulation Architecture Framework that enables development teams to integrate algorithmic models into a simulation solely through a collaboration layer/interface and software controls.

PathwaySim - Key Enabler for Care Coordination and Value-based Purchasing

PathwaySim is a revolutionary IT platform that provides coordination layer to orchestrate provider services and team-based care delivery for best Patient’s health outcomes.

Common goals for healthcare and other provider organizations include ;

  • monitoring, tracking, and optimizing workflow processes to save time and resources
  • detecting and eliminating bottlenecks or delays in the process value chain
  • improving communication and coordination among process participants providing each the data they need to make their decisions

MS4 Me   Discrete Event Systems Specification (DEVS) Modeling Environment

MS4 Me is a powerful DEVS-based environment for design, development, and implementation of IT-integrated systems of systems. MS4 Me is implemented with Eclipse RCP technology providing easy-to-use sequence diagram, natural language interface, and System Entity Structure ontology features.

Net-Centric Test Agent Capability (NTAC)

Net-Centric Test Agent Capability (NTAC) is a software architecture that automates generation of client agents the multilevel test observer agents that perform difficult and costly realistic operational testing.

NTAC can provide innovative SOA testing unlike current commercial SOA testing tools.

  • Load testing and regression testing in multiple locations through the DEVS/SOA environment
  • Work flow scenarios tested on the distribution environment
