The advent of new technologies brings a significant impact on systems management. The Industry 4.0 looks for increasingly automated, integrated, and digitised processes. We highlight the use of simulation as a Digital Twin, a virtual and intelligent copy capable of mirroring real processes and optimise decision making. This paper analyses the applicability of the Discrete Event Simulation as a Digital Twin in a non-automated process, a challenging scenario on the implementation of Industry 4.0 solutions. Amethod for conducting simulation projects of this nature was proposed, considering its integration with the process data, as well as its constant updating due to changes in the real environment. To verify its applicability, the method was used in a real study object. The proposed approach proved possible from the present research. We also present some discussions related to the use of simulation as Digital Twins, highlighting the main characteristics of such an application.

新技术的出现对系统管理产生了重大影响。工业4.0寻求日益自动化，集成和数字化的流程。我们重点介绍了将仿真用作Digital Twin，它是一种虚拟的智能副本，能够镜像实际流程并优化决策。本文分析了离散事件模拟作为数字孪生在非自动化过程中的适用性，这是实现工业4.0解决方案的极具挑战性的方案。考虑到它与过程数据的集成以及由于实际环境的变化而不断更新，提出了一种进行这种性质的仿真项目的方法。为了验证其适用性，该方法被用于实际的研究对象中。从目前的研究中证明了提出的方法是可能的。
