Decomposition and Coordination to Support Tradespace Analysis for Ground Vehicle Systems
Tradespace analysis is used to define the characteristics of the solution space for a vehicle design problem enabling decision-makers (DMs) to evaluate the risk-benefit posture of a vehicle design program. The tradespace itself is a defined by a multi-objective solution space (the tradespace) populated by individual design solutions including a set of Pareto design solutions. Designs within the tradespace are defined by a set of input variables whose performance is assessed through a set of functional objectives defined by vehicle simulations. These functional objectives represent individual objectives in a multi-objective optimization problem (MOP). The functional objectives are derived from a combination of simulations to determine vehicle performance metrics and direct calculations using vehicle characteristics. The vehicle characteristics represent vendor specifications of vehicle subsystems representing various technologies.
