Typical Architecture and System Integration of Digital Factories in Discrete Industries

Intelligent manufacturing is the main direction for manufacturing transformation and upgrading. As an important carrier of product intelligence and manufacturing process intelligence, digital factory is a key component of intelligent manufacturing. This paper starts with analyzing the key characteristics of digital factories in discrete industries, and investigates the overall architecture and connotation elements of digital factories including corporate resource planning, product life cycle management, manufacturing execution systems, logistics management and automation layers. By analyzing the typical business blueprint of the digital factory including product development and process management business process, production planning and execution business process, and product quality control business process, the key factor in the digital factory-system integration is illustrated.
