Our statistical analysis shows that, the classical double two-body model cannot be used to describe the kinematics of most hierarchical triple star systems on condition of observational accuracy nowadays (1mas) as a result of three-body effects. Even for the usual practical requirements, this model also cannot be used to figure those systems suffering significant three-body effects. Because it is not practical to use numerical ephemerides with a large volume of data to describe the kinematics of component stars in a star catalogue, a kinematics model, as simple and practical as possible, is needed for the hierarchical triple star systems. Based on the available observations and their associated fitting results, we obtain consistent mass parameters and initial conditions of six hierarchical triple star systems. How to outline the kinematics of these systems on the basis of practical requirements is also discussed.
