Abstract—The existing approach of SE to design of Socio-Economic Systems is an algorithmic method completed only through several iterative processes. Such an approach which depends on skill, knowledge, attitude, and experience (SKAE) of members of the design team is considered heuristic and does not give a formal theoretical framework to systems designers. This study has utilized principles of Axiomatic Design (AD) to resolve shortcomings of the existing models of SE; it serves to present a science-based model of SE to help design systems in a well-defined approach. In this regard, both “Cost” and “Complexity”; which arise from coupling among “System Requirements (FRs)” are eliminated. With the help of suitable examples, we show this approach to be superior to the existing ones in the field of SE. For the case-study, we use the existing design of demand-supply subsystem of U. S. electric power sector, based on data provided by the U.S. Energy Information Administration (EIA). The result for 2012 shows the symptoms of a poor design and ineffectiveness due to coupling among the FRs of this subsystem.
