On location problems on fuzzy graphs.

José A. Moreno Pérez, J. Marcos Moreno-Vega, José Luis Verdegay (2001)

Mathware and Soft Computing

Similarity:

Location problems concern a wide set of fields where it is usually assumed that exact data are known. However, in real applications, the location of the facility considered can be full of linguistic vagueness, that can be appropriately modeled using networks with fuzzy values. In that way arise Fuzzy Location Problems; this paper deals with their general formulation and the description solution methods. Namely we show the variety of problems that can be considered in this context and,...

Fuzzy XML queries via context-based choice of aggregations

Ernesto Damiani, Letizia Tanca, Francesca Arcelli Fontana (2000)

Kybernetika

Similarity:

A flexible query model is presented for semi-structured information stored in well-formed XML documents, modeled as XML fuzzy graphs by computing estimates of the importance of the information associated to XML elements and attributes. The notion of fuzzy graph closure with threshold is then used to obtain a fuzzy extension of the XML fuzzy graphs’ topological structure. Weights associated to closure arcs are computed as a conjunction of the importance values of the underlying arcs in...

A Method to Construct an Extension of Fuzzy Information Granularity Based on Fuzzy Distance

Thien, Nguyen Van, Demetrovics, Janos, Thi, Vu Duc, Giang, Nguyen Long, Son, Nguyen Nhu (2016)

Serdica Journal of Computing

Similarity:

In fuzzy granular computing, a fuzzy granular structure is the collection of fuzzy information granules and fuzzy information granularity is used to measure the granulation degree of a fuzzy granular structure. In general, the fuzzy information granularity characterizes discernibility ability among fuzzy information granules in a fuzzy granular structure. In recent years, researchers have proposed some concepts of fuzzy information granularity based on partial order relations. However,...

On somewhat fuzzy semicontinuous functions

G. Thangaraj, Ganesan Balasubramanian (2001)

Kybernetika

Similarity:

In this paper the concept of somewhat fuzzy semicontinuous functions, somewhat fuzzy semiopen functions are introduced and studied. Besides giving characterizations of these functions, several interesting properties of these functions are also given. More examples are given to illustrate the concepts introduced in this paper.
