Definition of value in the framework of systems engineering design methodologies with aeronautics insight

Abstract

Value is a polysemic word when used in engineering design, suitable to create fully-optimized entities. However, its multifaceted nature can hinder the development of effective design approaches. To address that, this research aimed at systematically reviewing the value definitions found across literature to establish a common theoretical basis for future value-based design methodologies. Considering the importance of value in the aeronautical sector, this research was performed both from a general viewpoint and focusing only on aeronautical papers. The main result achieved is the lack of a general-valid value definition, requiring deeper investigations of every element concurring to generate value.
