An Effort to Increase the Assembling Process Outputs of Superstar Model Shoes by Reducing Cycle Time Based on Quantification of Fuzzy Failure Mode and Effect Analysis (Fuzzy FMEA)

Abstract

Based on observations at PT. Parkland World Indonesia, 17C assembling line is known to never reach the production target compared to other lines with the same process, this is the lowest of the 13 lines in Building 2. To analyze the assembling process, Fuzzy Failure Mode and Effect Analysis (Fuzzy FMEA) tools are used to obtain the highest risk priority number (RPN) and Fuzzy risk priority number (FRPN) as a reference for priority improvements. 8 assembling sub-processes are known to be in the not ideal category, so that the severity, occurrence, and detection must be assessed and processed into FRPN output using the matlab application. Corrective action is carried out by the Process Activity Mapping method to be able to classify each activity so that the type VA (value added), NVA (non value added), and NVAN (non value added but necessary) can be identified. Every NVA activity will be removed to reduce CT. After repairs, the total CT of the assembling process was successfully reduced. On the first day of repairs, the output produced increased by 57pairs/ day. In addition, the results of the recalculation show that the FRPN value of the repaired process has decreased, which indicates that the process has undergone improvement.
