Set-Based Design, Model-Based Systems Engineering, and Sequential Decision Processes

摘要

An emerging concept to overcome the challenges of exploring a large, complex and expensive solution space such as with Department of Defense systems is to employ Set-Based Design tightly coupled to Model-Based Systems Engineering, and to treat the design process formally as a Sequential Decision Process in order to enable its analysis. This concept recognizes that designers start with a broad set of potential solutions, apply models of lower fidelity and analysis techniques in the design process to reduce the size of the consideration set. and then sequentially advance through smaller sets of solutions using models of increasing fidelity that help provide tighter bounds until a design is selected. This paper summarizes ongoing research and presents theoretical developments in the formalization of the Sequential Decision Process modeling coupled to Set-Based Design and Model-Based Systems Engineering.
