数字化工厂的概念是什么？
数字化工厂是随着数字仿真技术和虚拟现实技术发展而来的，它通过对真实工业生产的虚拟规划、仿真优化，实现对工厂产品研发、制造生产和服务的优化和提升，是现代工业化与信息化融合的应用体现。随着产品需求的不断变化、产品周期的更新换代速度提升，以及3D打印、物联网、云计算、大数据等新兴信息技术的不断应用，为了缩短研发周期，降低生产成本，提升企业产品质量和效益，先进的制造类企业开始越来越重视数字化工厂的建设，如上汽、海尔、华为、西门子等制造企业均已着手开始建设自己的数字化工厂，以支撑企业实现新的突破和发展。
作为信息化和工业化融合应用的最佳结合点，研究数字化工厂如何建设，探讨虚拟设计与物理设备之间怎样实现无缝衔接，对驱动信息化和工业化的深度融合发展、以及未来智能工厂发展具有十分重要的意义。数字化工厂具有广义和狭义的概念，其涉及的内容也随着分析的角度不同而有所区别。
本文数字化工厂结合国内离散型制造企业的实际情况（如兵器、航天等领域的部分制造企业），是以广义数字化工厂中核心制造企业为主，在满足自身生产和管理任务的同时，需要具备产品研发能力和售后服务保障能力，因此本论文中的“数字化工厂”不仅仅是生产的概念，它是向前延伸到设计，向后推移到服务，同时涵盖企业管理，包括产品研发设计过程、生产制造过程、企业管理过程、服务保障过程等产品全生命周期整个过程。

What is the concept of a digital factory?
Digital factory is with the development of digital simulation technology and virtual reality technology, it through the real industrial production of virtual planning, simulation optimization, to achieve the factory product development, manufacturing production and service optimization and improvement, is the application of modern industrialization and information integration embodiment. With the continuous change of product demand, the upgrading speed of product cycle. And the continuous application of emerging information technologies such as 3D printing, Internet of Things, cloud computing, and big data. In order to shorten the research and development cycle, reduce production costs. And improve the quality and efficiency of enterprise products, advanced manufacturing enterprises have begun to pay more and more attention to the construction of digital factories. Such as SAIC, Haier, Huawei, Siemens and other manufacturing enterprises have begun to build their own digital factories to support enterprises to achieve new breakthroughs and development.
As the best combination of informatization and industrialization, studying how to build digital factories and exploring how to achieve seamless connection between virtual design and physical equipment is of great significance to drive the deep integration of informatization and industrialization and the development of future smart factories.
The digital factory has broad and narrow concepts, and the content involved varies with the perspective of analysis.
In this paper, based on the actual situation of domestic discrete manufacturing enterprises (such as some manufacturing enterprises in the fields of weapons and aerospace). The digital factory is mainly a core manufacturing enterprise in the broad digital factory. While meeting its own production and management tasks. It needs to have the ability of product research and development and after-sales service guarantee. Therefore, the “digital factory” in this paper is not only the concept of production. It extends forward to design, backward to service. And covers enterprise management, including product development and design process, production and manufacturing process, enterprise management process, service guarantee process and other product life cycle.
