Generally, the system evolution is oriented toward the gradual diminution of human effect on the system. TRIZ is introducing the direction of technical system through the 'Law of Technology Evolution'. And Design Structure Matrix(DSM) can show the relationship among elements in a way easy to understand. Oh and Park stated that the direction of system evolution could be modeled by applying the ‘Law of Technology Evolution’ of TRIZ to DSM. This paper aims to validate the effectiveness by applying the evolution model - which applies DSM- to the hypothetical combat helicopter.
