  • SOME PROPERTIES OF FUZZY HILBERT SPACES AND NORM OF OPERATORS 

    Hasankhani, Abbas؛ Nazari, Akbar؛ Saheli, Morteza (University of Sistan and Baluchestan, 2010-10-01)
    In the present paper we define the notion of fuzzy inner productand study the properties of the corresponding fuzzy norm. In particular, it isshown that the Cauchy-Schwarz inequality holds. Moreover, it is ...

  • BEST SIMULTANEOUS APPROXIMATION IN FUZZY NORMED SPACES 

    Goudarzi, Mozafar؛ Vaezpour, S. Mansour (University of Sistan and Baluchestan, 2010-10-01)
    The main purpose of this paper is to consider the t-best simultaneousapproximation in fuzzy normed spaces. We develop the theory of t-bestsimultaneous approximation in quotient spaces. Then, we discuss the ...

  • Optimization of linear objective function subject to Fuzzy relation inequalities constraints with max-product composition 

    Shivanian, Elyas؛ Khorram, Esmaile (University of Sistan and Baluchestan, 2010-10-01)
    In this paper, we study the finitely many constraints of the fuzzyrelation inequality problem and optimize the linear objectivefunction on the region defined by the fuzzy max-product operator.Simplification ...

  • A RELATED FIXED POINT THEOREM IN n FUZZY METRIC SPACES 

    Merghadi, Faycel؛ Aliouche, Abdelkrim (University of Sistan and Baluchestan, 2010-10-01)
    We prove a related fixed point theorem for n mappings which arenot necessarily continuous in n fuzzy metric spaces using an implicit relationone of them is a sequentially compact fuzzy metric space which ...

  • FUZZY BASIS OF FUZZY HYPERVECTOR SPACES 

    Ameri, Reza؛ dehghan, omid reza (University of Sistan and Baluchestan, 2010-10-01)
    The aim of this paper is the study of fuzzy basis and dimensionof fuzzy hypervector spaces. In this regard, first the notions of fuzzy linearindependence and fuzzy basis are introduced and then some related ...

  • ON PRIME FUZZY BI-IDEALS OF SEMIGROUPS 

    Shabir, Muhammad؛ Jun, Young Bae؛ Bano, Mahwish (University of Sistan and Baluchestan, 2010-10-01)
    In this paper, we introduce and study the prime, strongly prime,semiprime and irreducible fuzzy bi-ideals of a semigroup. We characterize thosesemigroups for which each fuzzy bi-ideal is semiprime. We also ...

  • Numerical Methods for Fuzzy Linear Partial Differential Equations under new Definition for Derivative 

    Allahviranloo, Tofigh؛ Afshar Kermani, M (University of Sistan and Baluchestan, 2010-10-01)
    In this paper difference methods to solve "fuzzy partial differential equations" (FPDE) such as fuzzy hyperbolic and fuzzy parabolic equations are considered. The existence of the solution and stability of the method are ...

  • SOLVING BEST PATH PROBLEM ON MULTIMODAL TRANSPORTATION NETWORKS WITH FUZZY COSTS 

    Golnarkar, Ali؛ Alesheikh, Ali Asghar؛ Malek, Mohamad Reza (University of Sistan and Baluchestan, 2010-10-01)
    Numerous algorithms have been proposed to solve the shortest-pathproblem; many of them consider a single-mode network and crispcosts. Other attempts have addressed the problem of fuzzy costs ina single-mode ...

  • EXTRACTION-BASED TEXT SUMMARIZATION USING FUZZY ANALYSIS 

    Kyoomarsi, Farshad؛ Khosravi, Hamid؛ Eslami, Esfandiar؛ Davoudi, Mohsen (University of Sistan and Baluchestan, 2010-10-01)
    Due to the explosive growth of the world-wide web, automatictext summarization has become an essential tool for web users. In this paperwe present a novel approach for creating text summaries. Using fuzzy ...
