Cyber-Physical Systems (CPSs) combine the use of components from the physical and the digital worlds in a synergistic way. Cyber-Physical Production Systems (CPPSs), essential in Industry 4.0, result from the application of CPS principles to production environments. To promote the widespread implementation of CPPSs, it is necessary to study how to transform an existing production system with its integrated Enterprise Information Systems (EISs) into a CPPS. This is a very broad question and the scope of this work is limited to the concept development stage. The purpose of the paper is twofold: (1) to elaborate a meta-model for formalizing the elements that constitute CPPSs, with a particular emphasis on the involved EISs, and (2) to propose a method for supporting the transformation of an existing production system with its integrated EISs into a CPPS. Firstly, a literature review on the transformation methods towards CPPSs is carried out. It concludes that existing studies do not consider all aspects of CPPSs, especially its EISs, and that there is a lack of a method that analyzes the gap between the As-Is system and the To-Be system. As a result, a meta-model describing the main object classes that constitute CPPSs and the interrelationships among these classes, is proposed. Next, a method based on the meta-model is proposed to support the transformation into a CPPS. It provides a checking matrix to immediately visualize which improvement actions in the As-Is system are required. Furthermore, a case study illustrating the use of the method is presented. Finally, the contributions of the study are summarized and future work is highlighted.

网络物理系统（CPS）以协同方式结合了来自物理和数字世界的组件的使用。网络物理生产系统（CPPS）在工业4.0中必不可少，其源于将CPS原理应用于生产环境。为了促进CPPS的广泛实施，有必要研究如何将具有集成企业信息系统（EIS）的现有生产系统转换为CPPS。这是一个非常广泛的问题，这项工作的范围仅限于概念开发阶段。本文的目的是双重的：（1）精心设计一个元模型，以对构成CPPS的要素进行形式化，并特别强调所涉及的EIS，（2）提出一种方法，以支持将具有集成EIS的现有生产系统转换为CPPS。首先，对向CPPSs转化的方法进行了文献综述。结论是，现有研究并未考虑CPPS的所有方面，特别是其EIS，并且缺乏一种分析As-Is系统与To-Be系统之间差距的方法。结果，提出了描述构成CPPS的主要对象类别以及这些类别之间的相互关系的元模型。接下来，提出了一种基于元模型的方法来支持向CPPS的转换。它提供了一个检查矩阵，可以立即可视化按原样在系统中需要采取哪些改进措施。此外，还提供了一个案例研究，说明了该方法的使用。最后，
