Taxonomy MATE-CON buzzwords Decision Maker - Person who makes decisions that impact a system at any stage of its lifecycle Design Variable - Designer-controlled quantitative parameter that reflects an aspect of a concept Design Vector - Set of design variables that, taken together, uniquely define a design or architecture Attribute - Decision maker perceived metric measuring how well a defined objective is met Utility - Perceived value under uncertainty of an attribute Tradespace - Space spanned by completely enumerated design variables Pareto Frontier - Set of efficient allocations of resources forming a surface in metric space Exploration - Utility-guided search for better solutions within a tradespace Concurrent Design - Techniques of design that utilize information technology for real-time interaction among specialists Architecture - Level of segmentation for analysis that represents overall project form and function 9 Oct 2009 3
