ABSTRACT

According to the International Council on Systems Engineering (INCOSE), the definition of System-of-Systems (SoS) applies to a system of whose system elements are themselves systems; typically these entail large scale interest inter-disciplinary problems with multiple, heterogeneous, distributed systems. The perspective of System-of-Systems thinking supports system engineering techniques useful for conceiving and designing large and complex projects; these techniques must, of course, include the consideration of life cycle costs. COSYSMO follows a parametric modelling approach used to estimate the quantity of systems engineering labour, in terms of person-months, required for the initial life cycle stages until the deployment of large-scale software and hardware segments in a SoS. COSOSIMO (Constructive System-of-Systems Integration Cost Model), another current parametric model from the University of Southern California, includes activities such as the definition of the SoS architecture, the solicitation and procurement process for the SoS components and the integration of the SoS components into the SoS framework.
