Based on the conceptual framework and measurement method of system effectiveness developed via behavior analysis,this paper presents a layered model of objective tree and a contributory model characterized the behavior relationship between inner and outer elements of system.A set of computation formula is derived from the models which can be used to calculate the system effectiveness index and the system effectiveness factor.The contribution of inner and outer elements to the system effectiveness are discussed,which shows the reasonableness of the models and method.The methodology presented in this paper can be called contributory model method,or SEIF（System effectiveness index and factor） method, can be applied to the analysis and evaluation of system effectiveness.
