Industry 4.0 refers to the current trend of automation and data exchange in manufacturing technologies. It involves cyber-physical systems where physical objects are integrated with sensors and software to be monitored and controlled remotely. This allows for greater automation and customization in manufacturing. Some challenges for Indian companies adopting Industry 4.0 include the need for changes in management mindset, skills shortages, data management capabilities, and ensuring data security and standardization when implementing new technologies. Segments that could benefit most include production monitoring, supply chain management, part traceability, scheduling, and maintenance.
