In this paper, we focus on multiobjective integer programming problems with random variable coefficients in objective functions and/or constraints. For such multiobjective problems, after reformulation of them on the basis of an expectation optimization model and a variance minimization model for the chance constrained programming, incorporating fuzzy goals of the decision maker for the objecti...

a r t i c l e i n f o In this study, a fuzzy-boundary interval-stochastic programming (FBISP) method is developed for planning water resources management systems under uncertainty. The developed FBISP method can deal with uncertainties expressed as probability distributions and fuzzy-boundary intervals. With the aid of an interactive algorithm woven with a vertex analysis, solutions for FBISP m...

We present smooth formulations of common vortex detectors that allow a seamless integration into the concept of interactive visual analysis of flow simulation data. We express the originally binary feature detectors as fuzzy-sets that can be combined using the linking and brushing concepts of interactive visual analysis. Both interaction and visualization gain from having multiple detectors con...

It presents original resolution rule together with algorithm DCF Detection of Consequent Formulas developed especially for fuzzy logic with evaluated syntax. REASONING IN FUZZY PREDICATE LOGIC WITH EVALUATED SYNTAX The prob...

This text motivates and defines a generic model for interactive (online or offline) product catalogs. Based on a detailed requirements analysis, the data model is defined using an object-oriented design notation and the querylanguage for expressing customer interests on the catalog is defined using techniques from fuzzy set theory. The model provides the basis for the implementation of a generi...

The concept of (fuzzy) probability density function of fuzzy random variable is proposed in this paper. Due to the "resolution identity", we can construct a closed fuzzy number from a family of closed intervals. Using the same technique, we can construct the (fuzzy) probability density function of fuzzy random variable from the known probability density function. The basic idea of the new metho...

We present a fuzzy-theory based approach to coreference resolution and its application to text summarization. Automatic determination of coreference between noun phrases is fraught with uncertainty. We show how fuzzy sets can be used to design a new coreference algorithm which captures this uncertainty in an explicit way and allows us to define varying degrees of coreference. The algorithm is e...

Fuzzy Predicate Logic with Evaluated Syntax (FPL) (Novák, V.) is a well-studied and wide-used logic capable of expressing vagueness. It has a lot of applications based on robust theoretical background. It also requires an efficient formal proof theory. However the most widely applied resolution principle (Dukić, N.) brings syntactically several obstacles mainly arising from normal form transfor...
