How to define a digital factory and what is the relationship with smart factory and industry 4.0

The digital factory system is showing charming colors , The manufacturing industry is being attracted by its light . But in the glow , Many enterprises are also confused by various contradictory and entangled concepts , Everyone wants to have an artifact that can open everything . And the digital factory , It is indeed a light path with a clear track , It's guiding , Those who move towards understanding smart factories and industries 4.0 The only way . 

  One 、 Definition of digital factory

Although there are more and more researches on digital factory at home and abroad , But there is no unified conclusion about the definition of digital factory . For now , There are two definitions of a digital factory , One is generalized , One is in a narrow sense .

Generalized digital factory ： The core enterprise is the manufacturing enterprise that produces products or provides services , And associated members , Including core manufacturing enterprises 、 supplier 、 Software system service provider partners 、 Collaborators 、 Customer 、 distributor 、 Banks, etc , A dynamic alliance that digitises all information in its production and operation .

Digital factory in a narrow sense ： To manufacture resources （resource）、 Production operation （operation） And the product （product） At the core , Based on product life cycle data , Apply simulation technology 、 Virtual Reality Technology 、 Experimental verification technology, etc , The product is in the production station 、 Production units 、 Virtualization of all the real activities in the production line and the whole factory , And the process of machining and assembly is simulated 、 test 、 analysis 、 An optimized integrated organization .

actually , This is also in line with the actual understanding of factories and enterprises . Digital factory digitizes product information 、 Process information digitalization and resource material information digitalization , And make these three kinds of digital streams combine effectively , It is the manufacturing process of a real factory （ Including design 、 Performance analysis 、 Process planning 、 Processing and manufacturing 、 Quality inspection 、 Production process management and control ）, A mapping on a computer .

Two 、 Digital factory 、 Smart factory and industry 4.0

Industry 4.0 There are too many official words , In short , There are two dimensions , The technology dimension is the application of the Internet of things and services in the manufacturing industry , The business dimension is user driven . The two themes are familiar to readers , One is “ Smart factory ”, Focus on intelligent production system and process , And the realization of networked distributed production facilities ; Two is “ Intelligent production ”, It mainly involves the production logistics management of the whole enterprise 、 Human computer interaction and 3D Application of technology in industrial production process, etc .

Digital factory and Industry 4.0 The distance between them is a smart factory .

About industry 4.0 Phases and implementation prerequisites for , Professor liuqiang of Beihang University said a very classic “ Three don't principles ”, First of all , Don't do automation without mature technology , If the process is not mature , It's better to make a production line first , This is industry 2.0 Problem solved . second , Do not use information technology when management is not mature , This is industry 3.0 Problem solved . Third , Don't be intelligent without the foundation of networking and digitalization , This is industry 4.0 Problem solved .
