Single Minute Exchange of Die (SMED) is a method introduced by Shingo in early 1950s to reduce the setup time and provide quick equipment changeover and rapid die exchange. For 20 years, the revolution of SMED techniques helps the manufacturing field especially in production to minimize the changeover time process. During the last decade, the need of shorter setup time in changing die has increased due to market demand in all types of industries. The time reduction resulting from the conversion of internal setup to external setup time in SMED allows production time can be shortened. This makes the time reduction as a key point to improve performance in production line. However, most of the companies that are implementing the SMED pay more attention on reducing time in their activity, but do not take into consideration the performance during the entire time reduction process. During the time reduction process, without knowing, the unnecessary input such as cost, manpower and time might be consumed to obtain the targeted time that need to be reduced. Apart of that, the imbalance of inputs consumed from time to time will affect the performance and effectiveness of SMED. There are three objectives of this research which is to develop a model to measure the performance of SMED along the implementation of it in the manufacturing company. Then, to measure the fair distribution among selected parameters using Shapley Value and finally is to measure the performance of trends of activity and time using Moving Coalition Analysis (MCA) and Transpose-Moving Coalition Analysis (T-MCA). This research begin with data collection regarding activities involved in SMED for metal stamping production line. Findings the parameter that meet the scope for effectiveness measurement is most difficult part. In this research, data time of each activities is validate using DEA model which to measure SMED efficiency while Shapley Value will evaluate the fair distribution among selected players. The results from each method will be compared on which parameters and DMUs shows the best value. As a result, a suitable/relevant inputs and outputs for DEA model have been proposed to measure the SMED’s effectiveness of the conversion process in stamping production line. The activity involved in changeover process and the time consumed for activities are identified as parameter in determining the contribution of each activity in SMED. The same parameters is used for dynamic evaluation which focus on the trends in the time series for each periods and time series of overall activity respectively. The result from combination measurement technique can be used to measure how excellent the improvement done by understand the contribution of each efficiency in the changeover process. This combination method is used since the DEA model only can measure the efficiency of SMED, but Shapley Value will measure the contribution of each effectiveness throughout its implementation.
