An Exploration of the Role of System Level Variable Choice in Multidisciplinary Design

摘要

The process of designing large engineering systems can involve extensive sharing ofresources among many competing subsystems. These resources may be represented asdesign parameters that are shared between the system level and each subsystem.Frameworks for understanding the role of the choice of system level design variables onoverall system design may be valuable for the synthesis of complex engineering systems. Thispaper examines the outcome of Multidisciplinary Design Optimization (MDO) using threedistinct combinations of system level variables on a satellite design example. The results ofthese sets of system level variables are compared on their convergence time and robustness.
