New approaches and tools are needed to enable engineersto assess and deal with the environmental attributes ofmanufacturing processes. A special concern of addingenvironmental attributes to products and processes is dealingwith the tradeoffs associated with those attributes. Thepaper demonstrates the utility of the Analytic HierarchyProcess (AHP) when applied to the environmental streamlinedlife-cycle assessment (SLCA) of two manufacturingprocesses (chromic acid and boric/sulfuric acid anodizing).Two methods are detailed in the paper and the accompanyingSupporting Information. The application of AHP toabridged matrix-based tools adds value to a SLCA approachby providing logical consistency to valuing the matrixcells and increasing the speed of analysis. AHP also providesa built-in check on consistency that enables the user tomonitor the various comparison matrixes for logicalconsistency in assigning numbers to the cells of thematrixes.
