Abstract: If the individual component can not completely meet users’ needs, the method of components composition can be used to solve this problem. Checking whether the behaviors of combined component completely meet users’ needs is a key problem of components composition. Aiming at this problem, components composition approach based on behavior is proposed. It uses interface automaton to describe the behavior of components. To check whether the behaviors of combined component meet the users’ needs, a check method of composition existence based on behavior mapping graph is proposed. It gives the method of extracting users’ needs from the combined component.
