The Strategy of Process Innovation Based on AHP and TRIZ

Theory of the Solution of Inventive Problems (TRIZ) is an effective tool to solve the conflict in process system. Consequently, it is very important to find the key conflict in process innovation. This paper presents a new strategy of process innovation that integrates the analytical hierarchy process (AHP) and TRIZ to assist engineers in identifying and solving the key conflict. The proposed approach starts with analyzing requirements and constraints in the process system, and the AHP method is employed to investigate the most important conflict by evaluating overall criterions of the conflicts, and then TRIZ is used to solve the key conflict. Finally, the performance of the proposed approach is illustrated and validated with the case of machining blade.
