Abstract：
The concept of digital twins is one of the fundamental pillars of Industry 4.0. Digital twin allows the realization of a virtual model of a real system, enhancing the relevant performance (e.g., in terms of production rate, risk prevention, energy saving, and maintenance operation). Current literature presents many contributions pointing out the advantages that may be achieved by the definition of a digital twin of a water supply system. The Reference Architecture Model for Industry 4.0 introduces the concept of the Asset Administration Shell for the digital representation of components within the Industry 4.0 ecosystem. Several proposals are currently available in the literature considering the Asset Administration Shell for the realization of a digital twin of real systems. To the best of the authors\' knowledge, at the moment, the adoption of Asset Administration Shell for the digital representation of a water supply system is not present in the current literature. For this reason, the aim of this paper is to present a methodological approach for developing a digital twin of a water supply system using the Asset Administration Shell metamodel. The paper will describe the approach proposed by the author and the relevant model based on Asset Administration Shell, pointing out that its implementation is freely available on the GitHub platform.
摘要：
数字孪生的概念是工业4.0的基本支柱之一。数字孪生允许实现真实系统的虚拟模型，增强相关性能(例如，在生产率方面，风险防范,节能,和维护操作)。当前文献提出了许多贡献，指出了通过定义供水系统的数字孪生可以实现的优势。工业4.0参考体系结构模型引入了资产管理外壳的概念，用于工业4.0生态系统中组件的数字表示。目前，在考虑资产管理外壳的文献中，有几种建议可用于实现真实系统的数字孪生。据作者所知，此刻,目前的文献中没有采用AssetAdministrationShell进行供水系统的数字表示。出于这个原因,本文的目的是提出一种使用AssetAdministrationShell元模型开发数字供水系统孪生的方法论方法。本文将描述作者提出的方法和基于资产管理壳牌的相关模型，指出其实现可在GitHub平台上免费获得。
