Decision analysis and decision support are an area in which applications of fuzzy set theory have been found since the early 1970s. Still, there are areas, such as fuzzy control, that have gained much wider acceptance in practice than fuzzy decision analysis. This paper describes where fuzzy decision support stands now, and what would have to be done for it to gain wider acceptance. One of the major conclusions is that experimentation is needed and that empirical work in the engineering area is quite different from empirical work in human decision-making. Interdisciplinary teamwork may be much more important in the latter area than in the former.
