Abstract

This study aims to analyze the production line efficiency of electric pedicab assembly using the DMAIC (Define, Measure, Analyze, Improve, Control) method combined with the Ranked Positional Weight (RPW) method. The electric pedicab assembly line experiences imbalance issues characterized by bottleneck conditions and high idle time at several workstations. The DMAIC method is used to systematically identify problems, measure performance, analyze root causes, implement improvements, and control the results. The RPW method is applied to balance the production line by distributing work elements to workstations based on positional weight and precedence constraints. The results show that the integration of DMAIC and RPW methods can reduce idle time, eliminate bottlenecks, and increase production line efficiency. This combination provides a more systematic and optimal solution compared to using a single method. The research contributes to filling the gap in previous studies that have not specifically combined DMAIC with RPW in the context of electric vehicle assembly.

Abstract

The transition from conventional vehicles to electric vehicles offers a sustainable urban transportation solution. However, the reliability of electric vehicles, as the primary propulsion component, is critical to safety and operational efficiency. This literature review aims to analyze the application of quality control methods, specifically the Seven Quality Control Tools and Failure Mode and Effect Analysis (FMEA), in maintaining electric vehicle performance in electric vehicles. The review method was conducted by synthesizing previous research related to electric vehicle failures, quality control tools, and risk management in the automotive and manufacturing industries. The review results indicate that the Seven Quality Control Tools are effective in identifying historical defect patterns such as overheating and bearing failure, while FMEA provides a proactive approach for calculating the Risk Priority Number (RPN) to prioritize mitigation actions. The integration of these two methods offers a comprehensive framework for improving product quality and operational reliability. It is concluded that the combination of reactive analysis (Seven Quality Control Tools) with proactive risk assessment (FMEA) is crucial for the development of reliable electric vehicle systems.
