Line Balancing Analysis Using the Rank Positional Weight Method to Improve OEE Value on the Machining Line in an Indonesian Automotive Company

Abstract

This study investigates the application of the Rank Positional Weight (RPW) method and line balancing techniques to improve Overall Equipment Effectiveness (OEE) and productivity on the machining line of an Indonesian automotive manufacturer. The automotive industry in Indonesia, particularly in the wake of the 2024 economic uncertainty, faces significant challenges such as reduced consumer purchasing power, rising vehicle prices, and disruptions in the global supply chain. PT XYZ, an automotive company, has faced inefficiencies in its production process, notably in its machining line, leading to high cycle times and low productivity. By implementing RPW and line balancing, the company aimed to optimize task distribution among operators and reduce production delays. This qualitative study employs a literature review methodology to examine existing research on RPW, line balancing, and OEE improvement in manufacturing systems. The findings demonstrate that RPW and line balancing significantly enhanced PT XYZ’s OEE from 75% to 89%, thereby increasing productivity and reducing operational inefficiencies. These results align with previous studies showing the effectiveness of these methods in improving manufacturing performance. The study concludes that RPW and line balancing are highly effective techniques for optimizing automotive manufacturing processes, offering practical solutions to address current challenges in the industry.
