This work show an applicattion of the genetic algorithm to resolve the inverse problem of accident reconstitution and to analise colisions between vehicles of deformable structure. It is determined how, with imposing of restrictions, final positions and deformations found at vehicles after collision, the optimization algorithmcan give the set of variables and parameters that probably conduct the vehicles to true initial condition. All the developed procedures were implemented at Simulink/Matlab.The optimization technique chose to resolve the inverse problem was the genetic algorithm because it is the most popular to solve complex problems that have a very large number of variables and a elevate dimension space solutions.
