Security and safety assurance of collaborative manufacturing in industry 4.0

Abstract

Industry 4.0 provides an ideal platform to support a direct interaction of humans and machines in adapting changes and uncertainties in system operations. However, a physical human-machine interaction must assure security and safety. The safety requirements of collaborative manufacturing are explored and the techniques to assure safety in different collaboration modes are investigated to identify the challenges of safety assurance of human–machine collaborations in shared workspaces. In addition, system-level safety requirements of collaborative manufacturing are discussed to reveal the importance of sustaining similar safety levels for all system components and tools in developing an integrated collaborative system.
