On decision criteria for one-shot decision with possibilistic information

In this paper, approaches for one-shot decision problems with partially known information characterized by possibility distributions are proposed. The procedure for one-shot decision consists of two steps. The first step is to identify which state of nature should be considered for each alternative. Eight kinds of criteria are introduced for choosing the states of nature called focus points. The second step is to evaluate alternatives based on the focus points. Using the proposed one-shot decision approach, a newsvendor problem with possibilistic information is analyzed.
