供应链数字孪生框架设计--供应链运作参考模型与系统体系研究

Supply Chain Digital Twin Framework Design: An Approach of Supply Chain Operations Reference Model and System of Systems

Jie Zhang, Alexandra Brintrup, Anisoara Calinescu, Edward Kosasih, Angira Sharma

摘要:

数字孪生技术被认为是供应链发展的有益途径。与传统的数字孪生(时间动态)不同,供应链数字孪生是一个时空动态系统。本文阐述了供应链数字孪生中的“双”是什么,以及如何将两者“孪生”来处理时空动态问题。基于系统论和供应链运作参考模型理论,提出了一个供应链数字孪生模型框架。该框架具有通用性,可以应用于各种类型的供应链系统。我们首先将供应链系统分解为统一的标准块,为采用数字孪生做准备。其次,采用供应链运作参考模型的思想,将每个区块内的基本供应链活动数字化,并解释如何使用现有的信息系统。然后,为供应链系统中的每个成员建立单独的子数字孪生模型。然后,运用系统的系统的概念,从供应链业务集成和信息系统集成的角度,将子数字孪生整合协调为供应链数字孪生。最后以一个简单的供应链系统为例说明了该模型的应用。

英文摘要:

Digital twin technology has been regarded as a beneficial approach in supply chain development. Different from traditional digital twin (temporal dynamic), supply chain digital twin is a spatio-temporal dynamic system. This paper explains what is 'twined' in supply chain digital twin and how to 'twin' them to handle the spatio-temporal dynamic issue. A supply chain digital twin framework is developed based on the theories of system of systems and supply chain operations reference model. This framework is universal and can be applied in various types of supply chain systems. We firstly decompose the supply chain system into unified standard blocks preparing for the adoption of digital twin. Next, the idea of supply chain operations reference model is adopted to digitise basic supply chain activities within each block and explain how to use existing information system. Then, individual sub-digital twin is established for each member in supply chain system. After that, we apply the concept of system of systems to integrate and coordinate sub-digital twin into supply chain digital twin from the views of supply chain business integration and information system integration. At last, one simple supply chain system is applied to illustrate the application of the proposed model.
