This paper aims to find the cause leading to aviation accident and put forward relevant prevention strategy from organizational level. 7 types of direct reason causing aviation accidents are analyzed and classifies by using method of System Theory and `Human-Machine-Environment' Model which was proposed out in previous. Then a Stat. on 21 Chinese civil aviation accidents happened from 1981 to 2008...
Differential Evolution (DE) is an efficient approach capable of handling non-differentiable, non-linear and multi-model objective functions. However, in convergence speed and global optimization, there is still much room for DE to be improved. In this paper, double best mutation operation and chaos Differential Evolution are proposed to improve DE algorithmpsilas optimized performance. The simulated...
