This applies to both the robustness and opportuneness models. The robustness and opportuneness functions can inform decision. Therefore, lower opportuneness is preferred to higher opportuneness. There are of course other valid representations of the robustness/opportuneness models. The opportuneness may be considered as the immunity to windfall success. Unlike the robustness function, the opportuneness function does not satisfice, it "windfalls". With this in mind, consider now info-gap's robustness and opportuneness models. For example, a change in decision increasing robustness may increase or decrease opportuneness. The robustness and opportuneness functions address, respectively, the pernicious and propitious facets of uncertainty. Clearly, info-gap's opportuneness model is an instance of the generic minimin model. Info-gap robustness and opportuneness analyses can assist in portfolio design, credit rationing, and other applications. The opportune-windfalling decision, formula 121, "minimizes" the opportuneness function on the set of available decisions.
