Résumé

Sensitivity analysis (SA) determines the effect of changing input quantities on the output quantities (solution) of an engineering model, but appears to be little emphasized pedagogically as a theme. It is an important tool for studying a variety of engineering analysis and design problems. In this paper (Part 1 of a 2-part series), we describe the fundamental concepts of SA and show its application to explicit engineering models in determining the relative importance of each input and of combinations of inputs, and in uncertainty analysis. We give a numerical example for pressure drop in a fixed-bed reactor.
