Fatigue Studies

CTI has been monitoring the progress of Fatigue Risk Management initiatives for many years, and in 2009 we made the decision to integrate a bio-mathematical model into our crew pairing and rostering software. A survey of the available models revealed that none of them incorporated the improved understanding of the biological pathways for the human circadian clock due to recent advances in molecular biology and genetic sequencing technologies.

CTI made the decision to develop an improved model.  The resulting BSAFR bio-mathematical model is based on these advances, and calibrated against a large number of published laboratory studies and studies on airline pilots.  At the same time, CTI engaged with researchers in the fields of chronobiology and sleep who also believe that models based on underlying physiology would lead to greater accuracy.

CTI is now an Essential Participant in the CRC for Alertness, Safety and Productivity, collaborating with world leaders in the fields of chronobiology, sleep and brain modelling from Harvard University, Monash University and the University of Sydney who are developing a bio-mathematical model that incorporates the significant advances in research that have occurred in the last five years.
