We consider a method for evaluation of kinematic parameters of movement of material objects, when they are under disturbances and when initial data are fuzzy. The method is based on application of membership functions. We state the limit conditions, which provide a preset trajectory of the object. The estimations of sensitivity are presented; as a result, we can determine the influence of multidimensional variation of disturbing effects on the kinematic properties of the material object and predict an optimal trajectory under minimal sensitivity to disturbances.
