摘要: Abstract The theory of three-way decision provides an effective tool for decision-making under uncertainty and incomplete information, when a two-way is difficult to make. Soft sets conceptualize represent special types uncertainty. In this paper, we suggest two plausible semantics soft modeling uncertainty, namely, multi-context possible-world semantics. Under the semantics, investigate represented by sets. We introduce qualitative model based on core support set. formulate quantitative a) transforming set into fuzzy set, b) resulting shadowed (i.e., approximation set), c) making with results bring additional insights sets, interval
