Abstract & Overview
A cyber physical system (CPS) is a complex system that integrates computation, communication, and physical processes.Digital manufacturing is a method of using computers and related technologies to control an entire production process.Industry 4.0 can make manufacturing more efficient, flexible, and sustainable through communication and intelligence; therefore, it can increase the competitiveness.Key technologies such as the Internet of Things, cloud computing, machine-to-machine (M2M) communications, 3D printing, and Big Data have great impacts on Industry 4.0.Big Data analytics is very important for cyber-physical systems (CPSs), digital manufacturing, and Industry 4.0.This paper introduces technology progresses in CPS, digital manufacturing, and Industry 4.0.Some challenges and future research topics in these areas are also presented.
