The vision of smart shop floor is based on the notion of Industry 4.0 that denotes technologies and concepts related to Cyber Physical Production Systems (CPPS). In smart shop floors CPPS monitors physical processes, creates a virtual copy of the physical world and makes decentralized decisions. CPPS allows virtual world to store data, process data, communicate and cooperate with each other in real time. Every physical entity in the smart shop floor is regarded as an autonomous intelligent logical unit that performs operations guided by distributed control functions. Moreover, computing power and optimization approaches are embedded into each logical unit to make decisions to agilely respond to frequent occurrence of unexpected disturbances at the shop floor. This report presents an architecture of smart shop floor based on physical, logical and communication layers that embed intelligent approaches within manufacturing processes. Future perspectives of the application of the artificial intelligent technologies in smart shop floor are also discussed with respect to both academic research and industrial implementation.
