  • CHARACTERIZATION OF REGULAR $Gamma$−SEMIGROUPS THROUGH FUZZY IDEALS 

    Dheena, P.؛ Coumaressane, S. (University of Sistan and Baluchestan, 2007-10-01)
    Notions of strongly regular, regular and left(right) regular $Gamma$−semigroupsare introduced. Equivalent conditions are obtained through fuzzy notion for a$Gamma$−semigroup to be either strongly regular or ...

  • PRICING STOCK OPTIONS USING FUZZY SETS 

    Buckley, James J.؛ Eslami, Esfandiar (University of Sistan and Baluchestan, 2007-10-01)
    We use the basic binomial option pricing method but allow someor all the parameters in the model to be uncertain and model this uncertaintyusing fuzzy numbers. We show that with the fuzzy model we can, with ...

  • SOME PROPERTIES OF NEAR SR-COMPACTNESS 

    Bai, Shi-Zhong (University of Sistan and Baluchestan, 2007-10-01)
    In this paper, we study some properties of the near SR-compactnessin L-topological spaces, where L is a fuzzy lattice. The near SR-compactness isa kind of compactness between Lowen's fuzzy compactness and ...

  • RESIDUAL OF IDEALS OF AN L-RING 

    PRAJAPATI, ANAND SWAROOP (University of Sistan and Baluchestan, 2007-10-01)
    The concept of right (left) quotient (or residual) of an ideal η by anideal ν of an L-subring μ of a ring R is introduced. The right (left) quotients areshown to be ideals of μ . It is proved that the right ...

  • A NOTE ON THE ZIMMERMANN METHOD FOR SOLVING FUZZY LINEAR PROGRAMMING PROBLEMS 

    SAFI, MOHAMMADREZA؛ MALEKI, HAMIDREZA؛ ZAEIMAZAD, EFFAT (University of Sistan and Baluchestan, 2007-10-01)
    There are several methods for solving fuzzy linear programming (FLP)problems. When the constraints and/or the objective function are fuzzy, the methodsproposed by Zimmermann, Verdegay, Chanas and Werners are ...

  • COUNTABLY NEAR PS-COMPACTNESS IN L-TOPOLOGICAL SPACES 

    Bai, Shi-Zhong (University of Sistan and Baluchestan, 2007-10-01)
    In this paper, the concept of countably near PS-compactness inL-topological spaces is introduced, where L is a completely distributive latticewith an order-reversing involution. Countably near PS-compactness ...
