Blockchain for cyber-physical system in manufacturing

This paper proposed a blockchain manufacturing framework that involves the utilization of secondary validation and collaborative distribution concepts. Conventional and blockchain manufacturing simulators were developed to investigate the effects of blockchain technologies on manufacturing systems in terms of time and product quality. The simulation results illustrated that the products manufactured in the blockchain-based system are of better quality than the conventional system but does not necessarily reduce the manufacturing times due to the secondary validation and collaborative distribution processes, which are also responsible for ensuring manufacturing quality. The results also emphasized the importance of utilizing collaborative distribution models to improve workcell utilization within blockchain-based systems. By implementing the collaborative distribution logic within the blockchain, the manufacturing times will be lessened. This paper highlights the potential of utilizing blockchain technologies to enhance Cyber-Physical Systems in the manufacturing industry.
