D Factories, or Digital Factories, are modern manufacturing facilities that leverage advanced technologies like automation, artificial intelligence, and data analytics to enhance production processes. These factories focus on creating smart, interconnected systems that improve efficiency, reduce waste, and enable real-time monitoring of operations. In a D Factory, machines and equipment are often connected through the Internet of Things (IoT), allowing for seamless communication and data exchange. This connectivity helps manufacturers respond quickly to changes in demand and optimize their supply chains, ultimately leading to more agile and competitive production environments.
