Tripled partially ordered sets
In this paper, we introduce tripled partially ordered sets and monotone functions on tripled partiallyordered sets. Some basic properties on these new dened sets are studied and some examples forclarifying are given.
متن کاملA possibilistic handling of partially ordered information
In standard possibilistic logic, prioritized in formation are encoded by means of weighted knowledge bases. This paper proposes an exten sion of possibilistic logic to deal with partially ordered information which can be viewed as a family of possibilistic knowledge bases. We show that all basic notions of possibilis tic logic have natural counterparts when dealing with partially ordered inf...
متن کاملRectangles are Better than Chains for Encoding Partially Ordered Sets
Partial orders have applications in various areas in computer science such as distributed systems, object oriented languages, knowledge representation systems and databases. In this paper we present a new technique to encode partially ordered sets or posets. Specifically, we use the family of two-dimensional posets, which we refer to as rectangles, to encode a given poset; an element x is less ...
متن کاملRevision of Partially Ordered Information: Axiomatization, Semantics and Iteration
This paper deals with iterated revision of partially ordered information. The first part of this paper concerns the Katsuno-Mendelzon’s postulates: we first point out that these postulates are not fully satisfactory since only a class of partially ordered information can be revised. We then propose a suitable definition of faithful assignment, followed by a new set of postulates and a represent...
متن کاملReasoning with partially ordered information in a possibilistic logic framework
In many applications, the reliability relation associated with available information is only partially defined, while most of existing uncertainty frameworks deal with totally ordered pieces of knowledge. Partial pre-orders offer more flexibility than total pre-orders to represent incomplete knowledge. Possibilistic logic, which is an extension of classical logic, deals with totally ordered inf...
