Abstract: | This paper presents summary statistics regarding the characteristics of decisions identified in a recent review of 86 applications of decision analysis. The goals of this summary are (1) to identify values for important parameters which characterize the structure of decisions which have been analysed using decision analysis; (2) to see what proportion of studies use the various available analysis tools; and (3) to draw implications from these results, particularly in terms of simplifying applied decision analysis. The results show that decisions tend to be multiattributed, involve a modest number of alternatives, and uncertainties appear to be the major source of influence on the chosen alternative. Furthermore, applications generally appear to take advantage of tools dealing with problem structuring, assessing uncertainty and performing sensitivity analysis. |
