Research into the development methods of Cyber-Physical Systems (CPSs) and their requirements within the lifecycle of Electrical and Electronic Equipment (EEE) is presented in this thesis. CPSs are a prominent research area, building on concepts such as the Internet of Things, Ambient Intelligence and Intelligent Products. There is an industry led view that CPSs are a core aspect of the fourth industrial revolution (Industrie 4.0). There is currently a lack of documented CPS deployments within industrial environments, and available development tools and investigations into the challenges to consider when constructing them. For CPSs to be adopted within industry it is important that they are developed robustly and methodically, meeting the requirements of the domain. Within this thesis the requirements of stakeholders at the Beginning of Life (BoL) and End of Life (EoL) stages of the EEE lifecycle have been recorded and compared.
