Traditional manufacturing and production systems are in the throes of a digital transformation. By blending the real and virtual production worlds, it is now possible to connect all parts of the production process: devices, products, processes, systems and people, in an informational ecosystem. This paper examines the underpinning issues that characterise the challenges for transforming traditional manufacturing to a Cyber Physical Production System. Such a transformation constitutes a major endeavour for requirements engineers who need to identify, specify and analyse the effects that a multitude of assets need to be transformed towards a network of collaborating devices, information sources, and human actors. The paper reports on the e-CORE approach which is a systematic, analytical and traceable approach to Requirements Engineering founded on a ‘capability-oriented’ paradigm with particular emphasis on ‘early requirements’. The utility of the approach is demonstrated using two use cases from an industrial-size application in the automotive industry and specifically the case of requirements of Fiat Chrysler Automobiles.

传统的制造和生产系统正处于数字化转型的阵痛之中。通过融合真实和虚拟的生产世界，现在可以在信息生态系统中连接生产过程的所有部分：设备，产品，过程，系统和人员。本文探讨了将传统制造业转变为网络物理生产系统所面临挑战的基本问题。对于需要识别，指定和分析需要将大量资产转换为协作设备，信息源和人类行为者网络的影响的需求工程师而言，这种转换是一项主要工作。该论文报告了一种系统的e-CORE方法，需求工程的分析和可追溯方法基于“面向能力”范式，特别强调“早期需求”。使用两个来自汽车行业工业规模应用的用例，特别是菲亚特克莱斯勒汽车的要求，证明了该方法的实用性。
