Abstract: System subdivision always is involved in the information technology domain,and a commonly used method is the U/C Matrix.However, the system complexity and the factor of people will cause some critical problems,such as inefficiency,uncertainty and mistakenly division .Consequently,the relationship between system and subsystems,subsystems and functions,functions and data,as well as properties of these relationships were discussed.The subsystem hierarchically clustered according to the simulation of functions was measured by structure entropy and Hpal entropy,and a series of computational formula were given.This new way of system subdivision changes the things finished by people to computation.Meanwhile,a prototype system was accomplished and a case study was analyzed to verify the theory.

Key words: System subdivision,Hierarchical clustering,Structure entropy,U/C matrix,Function similarity
