This thesis presents a Spine Design Process (SDP) combining Axiomatic Design Theory to provide a unified understanding of the design process for Cyber Physical System (CPS) early stage design analysis.The thesis begins with an overview of CPS and recent literature relating to problem solving and creative thinking process, design principles and philosophies, and design process models in the areas of mechanical, software, and multidisciplinary. The literature found that there is lacking a unified view of process models in different engineering domains that could fully support the design and analysis of CPS. For the scope of CPS, it is necessary to form a model that capable of covering several process models to generate a unified design process.Following the literature review, a SDP process model is proposed to serve as a unified approach for CPS system design, adapting concepts from problem solving process, axiomatic design, and engineering design process models. The SDP process consists of six main stages namely: analysis, interpretation, concept, elaboration, construction, and operation. Axioms, the essence of design described in Axiomatic Design Theory, are used in each design stage for design evaluation and validation. The process illustrating a sequential prescriptive design approach potentially can be used in general cases of CPS design. The unified approach in SDP provides a new way of combining design processes in different engineering domains by using Axiomatic Design Theory. Two case studies were conducted to evaluate the use of the proposed process model. The first case study describes the use of the process in designing and analysing of an automation cake icing forming system. The system uses a four degrees of freedom robotic arm and a vision system to complete the task. The process was used to analysis the hierarchy structure of the system as well as design validation and evaluation. The second case study presented in the thesis analyses the architecture design of a virtual reality system that is used to simulate and model coal shearer. The use of the process took a top down approach in analysing the existing structure of the system.In conclusion, it is found that a unified view of design process can be used to support design analysis and systematic thinking of a design project and Axiomatic Design Theory is useful for design and validation of CPS. In addition, the thesis extends the use of Axiomatic Design Theory to CPS systems for it provides strong analytical method for system evaluation which is useful in SDP process model.
