  • Using wind direction incorrectly or misidentifying agent type.

Finally, some of the contextual factors under which the processes from Figure 2 are performed include:

  • An awareness of high false alarm rates,

  • An awareness of high risk,

  • Fatigue,

  • Location: CONUS or OCONUS,

  • Time pressure,

  • Environmental stressors (heat, noise, etc.).

CONCLUSION

The proposed HFA will capture most of the cognitive tasks, common errors, and contextual factors via the event and evidence likelihoods in conjunction with the procedural tasks and resource knowledge programmed into the source code. Results from the initial HFA have demonstrated synthesis of information from multiple sources and formation of hypotheses on the potential types of CBRN attacks and highlight the information required for a firm conclusion about the CBRN environment.
