Abstract: Digital Twin technology is becoming very important in modern manufacturing systems. A digital twin is basically a virtual model which represents a physical machine, process or system. With help of sensors, IoT and data analytics the digital model continuously receives data from real environment and behaves almost same as the physical system. Because of this, industries can monitor, simulate and optimize production process without disturbing the actual machines. In recent years, the use of digital twins has grown in smart factories, predictive maintenance and process optimization. This paper presents a review on development of digital twins for manufacturing processes. The study discusses the concept, architecture, enabling technologies, and applications of digital twin in manufacturing sector. Some challenges such as data integration, modeling complexity and cyber security are also discussed. The paper also highlights future research directions in digital twin based manufacturing systems. Overall, digital twin technology is expected to play a significant role in Industry 4.0 and intelligent production systems.
