According to the managers in manufacturing fields who is lack of the capability for evaluating the priority of improving points directly and efficiently. It causes the wastes of strengths and time, but the results are not as good as prediction. In this study, we integrate the value stream mapping and analytic hierarchy process to construct the “Hierarchical Value Stream Evaluation Process, HVSEP”. This scientific tool with logical system could assist the user to evaluate the priority of improving points. The productivity per people increased 10.64% after importing HVSEP. It proves that the HVSEP is feasible and effective by verification of real case.
