[1234] Behavior-Based Indicator Reduction Technique for Evaluating the Sustainability of Concrete
キーワード：analytic hierarchy process, indicator selection, indicators, sustainable concrete
Concrete sustainability evaluation needs less but valuable indicators. A technique using the coefficient of variation to eliminate progressively indicators from an exhaustive set to form reduced sets of indicators is presented. The effect of the reduction was evaluated using analytic hierarchy process, suggesting that the ranking of alternatives is less sensitive to the omission of trivial indicators, thereby, leading to the identification of the relatively most sustainable concrete mix. This technique, therefore, has significant applications in indicator selection for sustainable concrete analysis.
