요약Increasing complexity in engineering design has resulted from the continuous advancement of technology over the past few decades. Over the years, engineers haveexplored various ways to manage complexity during the different design phases. Thishas led to the emergence of Systems Engineering. The initial and traditional effortsin systems engineering were document-centric. Documents were used to describe systems, communicate with stakeholders, and collaborate with teams. However, thiscame with certain challenges, including difficulty updating these documents due tothe static nature of paper, some valuable information lost in the communication process, and difficulty managing large amounts of information.Recent years have seen a paradigm shift from document-based to model-basedapproaches in the form of Model-Based Systems Engineering (MBSE). In MBSE, theengineer's work is centered around the model, which is the key artifact of the systembeing designed. The model also serves as a single source of truth for the system,allowing for improved communication, quality, productivity, reduced risks, and cost.Though, with MBSE being a relatively new area of systems engineering, it comes withits challenges. Existing MBSE methodologies are high-level and lack clear criteria onhow to properly decompose a system. In addition to its high learning curve and highinvestment cost, the adoption of MBSE may lead to issues with tool integration andcompatibility, depending on the organization.Despite the introduction of MBSE, many systems engineering practices are stillbased on heuristics, and engineers rely on prior experience or trial and error approaches to implement systems engineering methods. Although existing methodologies outline important aspects of the system design process, they do not define orprovide guidance on how these aspects should be achieved. Recently, InternationalCouncil on Systems Engineering (INCOSE), the systems engineering professional society, together with engineers have tried to establish industry standards to formalizethe application of systems engineering. Some of these include the use of SystemsModeling Language (SysML) as the de facto language to describe general-purposesystems and the establishment of various methodologies for designing complex systems. INCOSE has also sought to establish formal and theoretical methods in systemsengineering that are grounded in science and mathematics. Using formal and theoretical methods, a system can be represented and the relationships between its elementscan be better understood.Integrated Product and Process Development (IPPD) has emerged as a systematic approach to manage the development of complex systems from early integrationthrough a system's life cycle and could be considered the overall construct for systemdesign problems. A fundamental aspect of the IPPD process is the decompositionaspect of the system. The decomposition of a system consists of the different viewsused to understand and represent a system, from the customer and stakeholder requirements to the physical design. With the emergence of MBSE, Requirements,Functional, Logical, and Physical (RFLP) is an important framework used in systemdecomposition. However, similar to many MBSE approaches, the RFLP frameworkoperates at a high level and does not provide guidance on decomposing stakeholderrequirements into the system's functional, logical, and physical architecture. This ledto the motivating question for this dissertation, with the aim to explore ways to improve and effectively translate the decomposition process within the RFLP frameworkinto a system design that satisfies stakeholder requirements.
