Multiplication of Air Accidents Frequency and Hazard Desirability Coefficients for ICAO Safety Risk Tolerability Matrix Solution

Sergey Pavlovich Borsuk, Oleksiy Reva, Volodymyr Kharchenko


Using mathematical method of priorities arrangement, also known as problem “about leader”, air accidents frequency and hazard desirability coefficients were found. Those coefficients are proposed by ICAO for safety risk tolerability matrix solution. Integral index of mentioned parameters combinations hazard is found with help of Harrington desirability function. Risk levels determination index is introduced for researched matrix.
