In this study, the method to infer the situation of child's downfall accident by computer simulation was constructed. In the simulation, child multi-body model based on real children's body dimensions and actual spiral stairs model were used. Objective function based on a fall point after the accident was determined and a response surface was constructed to estimate the relationship between the objective function and input variables of the simulation. The circumstances of pre-accident were inferred by using genetic algorithm. The method was applied to a real accident and the estimated situation approximately corresponded to the real accident. The method showed the possibility to estimate the accident circumstances in a real accident.
