“…However, near Pareto solutions are often recognized as being valuable and perhaps even superior solutions to true Pareto solutions from an engineering standpoint. These near Pareto solutions can be found using a decomposition and coordination approach, as described in (de Castro et al, 2022;Wiecek and de Castro, 2022). The ability to decompose the multi-dimensional tradespace into subspaces may provide more solutions for decisionmakers to work with.…”

This paper discusses approaches for tradespace analysis, exploration, and visualization to address multi-objective decision-making. Next, computational tools for early-stage tradespace analysis to enhance programmatic decision-making are introduced via a vehicle design example to demonstrate the effectiveness and capability of the method. Using a smaller sample of technologies in this problem a synthetic tradespace spans the space of potential and available solutions and provides an opportunity for design engineers to develop an insight into possible technologies and solutions within the tradespace.
