Fuzzy XPath through Fuzzy Logic Programming

New Generation Computing, 2015
In this paper we present a fuzzy variant of the XPath query language for the flexible information retrieval on XML documents. Our main purpose is to provide a repertoire of operators that offer the possibility of managing satisfaction degrees by adding structural constraints and fuzzy operators inside conditions, in order to produce a ranked sorted ...

Fuzzy solution in fuzzy linear programming problems

IEEE Transactions on Systems, Man, and Cybernetics, 1984
Conventional mathematical programming problems are to maximize an objective function subject to constraints. In the real decision problems, however, a satisfaction criterion might be more useful than a criterion of maximizing an objective function in making the decision under fuzzy constraints.

Fuzzy mathematical programming

Computers & Operations Research, 1983
This chapter introduces a type of mathematical programming, in which not all constraints have to be crisp, i.e. in which certain violations of the constraints are tolerable. Also the goals do not have to be maximized or minimized as in classical mathematical programming, they are substituted by aspiration levels, that have to be met as well as possible.

Interactive fuzzy programming for multi-level linear programs with fuzzy numbers

1998 Second International Conference. Knowledge-Based Intelligent Electronic Systems. Proceedings KES'98 (Cat. No.98EX111), 2002
In the fuzzy programming for multi-level linear programming problems developed by Lai et al. (1996), since the fuzzy goals are determined for both an objective function and decision variables at the upper level, undesirable solutions are produced when these fuzzy goals are inconsistent.

FUZZY PROGRAMMING WITH RECOURSE

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2005
In this study, we deal with the optimization methodology in fuzzy decision-making systems. The issue of convergence for sequences of integrable fuzzy variables is discussed. Based on credibility theory, a new class of fuzzy programming—two-stage fuzzy programming or fuzzy programming with recourse problem is introduced, and a discussion about basic ...

Fuzzy arithmetic on LR fuzzy numbers with applications to fuzzy programming

Journal of Intelligent & Fuzzy Systems, 2015
In practice, some special LR fuzzy numbers, like the triangular fuzzy number, the Gaussian fuzzy number and the Cauchy fuzzy number, are widely used in many areas to deal with various vague information. With regard to these special LR fuzzy numbers, called regular LR fuzzy numbers in this paper, an operational law is proposed for fuzzy arithmetic ...

Fuzzy and probabilistic programs

Information Sciences, 1976
In this paper, a general formulation of fuzzy programs or fuzzy algorithms is introduced. The relationship between this formulation and other existing formulations is studied.
