this paper processes a combined method, based on vikor and data envelopment analysis (dea) to select the units with most efficiency. we utilize the vikor as compromise solution method. this research is a two-stage model designed to fully rank the alternatives, where each alternative has multiple inputs and outputs. the problem involves belief parameters in the solution procedure. first, the alt...

We study relations between evidence theory and S-approximation spaces. Both theories have their roots in the analysis of Dempsterchr('39')s multivalued mappings and lower and upper probabilities, and have close relations to rough sets. We show that an S-approximation space, satisfying a monotonicity condition, can induce a natural belief structure which is a fundamental block in evidence theory...

A syntactical and a semantical framework are proposed for the modeling of a hierarchical belief structure and of a message characterized by its content and status. For a given message, a multiplayer belief revision rule that transforms any initial belief structure into a &nal belief structure is designed. Several accuracy relations are introduced in order to express the formal conditions under ...

There are important theoretical and practical reasons to study belief structures. Similar to qualitative probability, qualitative belief can also be described in terms of a preference relation. One of the objectives in this study is to specify the precise conditions that a preference relation must satisfy such that it can be faithfully represented by a belief function. Two special classes of pr...

For explaining theory change, it is important to be able to express which theory is believed to be fundamental and which theory is thought to be true. To achieve this expressive power, I propose theory of belief structures (TBS) that describes belief states not in terms of a set of sentences but by a structure. The dominant formal approach of belief revision, the AGM theory, adopts a conservati...
