4. Important developments to the RFS architecture and agent models that we have identified in this research include:
Enabling RFS agents and other models (such as MIDAS) interacting with RFS agents to remain synchronized at the same simulated time, e.g., controlled by a single master clock.
Enabling the networking agent to access information directly from agents other than vehicles
Developing a library of automatic measurement and statistical reporting agents
Upgrading the interfaces to allow dynamic updating of environmental agents (e.g., weather and CAT), which are currently assumed in RFS to be static
Developing a user interface to enable analysts other than RFS authors and programmers to construct and execute application system models out of existing component agent models.
5. Important developments to MIDAS that we have identified in this research include:
Enabling MIDAS and other models (such as RFS agents) interacting with MIDAS to be continually synchronized in simulated time, e.g., controlled by a single master clock
Enabling the MIDAS updateable world representation to be initialized dynamically as the simulation progresses for human operators that enter the simulation conditionally or otherwise at times later than the start (e.g., pilots of aircraft entering a sector)
Removing the current constraint on the number of human operators that can practically be simulated
Generalizing the code so that models of new human operators and of operator tasks and procedures can be created through data entry rather than code changes
Developing a user interface to enable analysts other than MIDAS authors and programmers to set up and execute human performance simulations.
Undertaking these recommended tests and developments will build credibility for and confidence in the application of human-centered, agent-based, fast-time simulation for aviation safety analysis.
