  7. Abstract:
  8. Functional Requirements (FR) are traditionally known to be "input" as far as an engineering process is concerned. However, for a Systems Engineer (SE), this is not the case. A well-known task of a SE is, in fact, to develop FRs from what is considered as the customer needs. The traditional approach to develop suitable FRs involves an algorithmic procedure; which mostly relies on the skills, knowledge, attitude, and experiences of the SE or experts members of design team. It is therefore an ad-hoc method which results in quite a few numbers of trial-errors and its effectiveness only reveals itself as time goes on. The current work aims to address such a shortcoming in Systems Engineering Process (SEP). We effectively employ the principles of Axiomatic Design (AD) to develop a set of FRs which are logical and follow some mathematics to the extent that they are close to being "provable". In fact, being provable, in real scenarios, corresponds to being "Traceable". Furthermore, the current work is quite efficient in mathematically addressing the coupling phenomenon in large-scale systems and so it would be helpful to improve any existing engineering system. Some case studies on power-generation and distribution reveals the strength of the current approach; nevertheless, further researches are necessary to investigate the emergencies and unseen abnormalities in the system; as far as the functional requirements are concerned
