document: Application of normal possibility decision rule to silence The paper presents the way of combining two decision problems concerning a single -LRB- or a common -RRB- dimension , so that an effective fuzzy decision rule can be obtained . Normality of the possibility distribution is assumed , leading to possibility of fusing the respective functions related to the two decision problems and their characteristics -LRB- decisions , states of nature , utility functions , etc. -RRB- . The approach proposed can be applied in cases when the statement of the problem requires making of more refined distinctions rather than considering simply a bi-criterion or bi-utility two-decision problem
