A military aircraft safety risk evaluation method based on “human-machine-environment system”

To solve the difficulties in the safety risk decision of the military aircrafts based on full life cycles, a military aircraft safety risk evaluation model was established on the basis of “human-machine” and “environment-machine”. A grey fuzzy analytic network process was also proposed for the insufficiencies of current safety risk decision methods used in the research and development of military aircrafts. By using this method to evaluate the safety performance, we can not only quickly rank the available schemes by their safety performance, but also find out the insufficiencies of these schemes. The advantages of this method in safety evaluation were finally verified by specific examples.
