Modeling the enablers of ergonomic design with Karakuri automation for special purpose machine manufacturing industry using the DEMATEL approach

The special purpose machine (SPM) manufacturing industry plays a pivotal role in enhancing production efficiency and meeting the specific demands of various industrial sectors. However, the pursuit of efficiency should not compromise the health and well-being of the workers involved in these processes. Ergonomic design is essential in ensuring that SPMs are designed and operated in a manner that minimizes physical strain and optimizes performance. The application of Karakuri automation, an integration of lean manufacturing techniques initiated by Japan, further enhances the efficiency of the SPM manufacturing shop floor. This research article presents a comprehensive analysis of the enablers of ergonomic design with Karakuri automation for the SPM manufacturing industry using the Decision-Making Trial and Evaluation Laboratory (DEMATEL) approach. The study aims to identify the key factors influencing ergonomic design decisions and their interrelationships, ultimately aiding in the development of more ergonomic and efficient SPM manufacturing.
