Author Name:
Jui-Chin Jiang, Thi-Anh-Tuyet Nguyen
Abstract:
ASBTRACT By integrating TRIZ methodology into the improve phase of the Lean Six Sigma approach as a quality improvement strategy, this study attempts to develop a better process to ensure high productivity and effectiveness, low waiting time to eliminate waste for the unnecessary inspection/transportation of product during the operation system, resulting in a more effective process system which becomes more stability and reliable. The corresponding design procedures and prediction models are provided. Further on, a case study on the Coffee Company is discussed with emphasis on the Robusta coffee process area. The result shows that the improved prediction models successfully reduces the waste of waiting time for inspection (46.54%) and the transportation time during the operation system (38.12%). That leads to a reduction of the Non Value Added time (38.12%). Keywords:- Lean Manufacturing, Six Sigma, Lean Six Sigma, DMAIC, D2MAIC, TRIZ
