Chemical, Biological, Radiological, and Nuclear Warning & Reporting (CBRN W&R) is a key component of force protection. The task of CBRN W&R and CBRN defense is largely coordinated and executed by a CBRN Cell that interacts with a wide range of individuals, environmental queues, and sensors in order to collect, synthesize, and analyze data pertaining to a possible CBRN attack. The work presented here describes a qualitative model of operations in a CBRN Cell and the associated performance and decision making as well as a translation of the qualitative model into a quantitative Human Factors Agent (HFA). The software implementation of the HFA will assess situations, take actions, and make errors as would a human CBRN W&R officer.
In order to create a model of CBRN W&R as it pertains to a CBRN Cell one must attempt to capture the procedures, response times, and mistakes the individuals operating within the Cell make during exercises and real-world situations. Individuals within a CBRN Cell are often inundated with messages from multiple sources via multiple communication devices and the challenges presented by this environment need to be captured and quantified in order to accurately represent the roll of the CBRN Cell.
The HFA is designed to take the place of a human-in-the-loop for testing and evaluation purposes. It is based on a qualitative model of human performance and factors within a CBRN Cell, developed through Cognitive Task Analysis (CTA). CTA techniques provide a set of tools for eliciting domain knowledge and key aspects of human performance and expertise within a given work environment. The HFA interfaces with the Joint Warning & Reporting Network (JWARN) as well as simulated communication devices (phone, fax, email, etc) for sending and receiving messages regarding the suspected CB event, carrying out the tasks of a CBRN Cell that are consistent with real-world practices.
