Transforming MSME assembly operations: smart manual assembly table for improved productivity

Micro, Small, and Medium Enterprises (MSMEs) play a crucial role in the manufacturing sector but often face challenges in maintaining ‎efficiency and quality due to high worker attrition and skill variability. Traditional manual assembly tables (TMATs) require experienced ‎operators, making it difficult for MSMEs to sustain productivity with novice workers. To address this, authors developed and implemented ‎a Smart Manual Assembly Table (SMAT) that integrates smart assistance technologies (SAT) to enhance industrial efficiency. The system ‎incorporates real-time monitoring, automated guidance, and error detection mechanisms to improve worker accuracy and productivity. ‎Experimental evaluation compared the performance of traditional and smart assembly setups, focusing on cycle time, error rate, and overall ‎workflow efficiency. The results demonstrated a significant reduction in assembly time and errors, enabling higher production rates and ‎improved product quality. Additionally, the SMAT reduced the cognitive load on operators by providing automated alerts and digital work ‎instructions, thereby enhancing adaptability for novice workers. The study also highlights the potential of integrating Industry 4.0 principles into MSME assembly operations, thereby enhancing a collaborative human-machine environment. The findings emphasize the practical benefits of ‎smart-assisted manual assembly cells, including cost-effectiveness, scalability, and ease of implementation. Future research should focus on ‎long-term reliability, adaptability across diverse assembly tasks, and optimized scheduling techniques to further improve efficiency. The SMAT presents a promising approach for modernizing MSME assembly processes, ensuring sustainable productivity and a competitive advantage in the evolving industrial landscape.
