Implementation of ergonomics and lean manufacturing principles to improve work environment and performance of soccer ball production line




lean, ergonomics, value stream mapping, REBA, performance improvement


Value addition and performance improvement are important to deal with increasing local and global market competitiveness. Interventions and automation based on Lean and ergonomics principles have strong influence on performance improvement of the production systems. This study focuses on implementation of lean manufacturing and ergonomics principles to improve work environment and performance of the soccer manufacturing production line. Work visualization and value stream mapping (VSM) techniques were employed to identify the opportunities for improvements. Time of value and non-value-added activities is recorded using time study method. Working postures and associated risk factors are evaluated using Rapid Entire Body Assessment (REBA) method. Lean manufacturing principles are employed to minimize wastes and non-value added activities. Similarly, improvements in work environment are made through ergonomics interventions. Various models comprising different levels of lean and ergonomics interventions were evaluated through simulation before actual implementation. The results of the finalized model in terms of decrease in cycle time (8.64 to 7.018 seconds), increase in daily production (20505 to 24176 soccer balls), and improved work environment are evident of performance improvements in all aspects. The integration of lean and ergonomics principles leads to improve the productivity and working environment for workers in soccer ball manufacturing industry.
