  • MINIMAL SOLUTION OF INCONSISTENT FUZZY MATRIX EQUATIONS 

    Mosleh, M.؛ Otadi, M. S.؛ Bagher Abadi, S. M. (Islamic Azad University, Central tehran Branch, 2011-01-01)
    Fuzzy liner systems of equations, play a major role in several applications in various area such as engineering, physics and economics. In this paper, we investigate the existence of a minimal solution of inconsistent fuzzy ...

  • IMPRECISE DATA ENVELOPMENT ANALYSIS APPROACH IN PERFORMANCE EVALUATION OF SUPPLY CHAIN 

    Mamizadeh Chatghayeh, S.؛ Abbasi, V. (Islamic Azad University, Central tehran Branch, 2011-01-01)
    Spurred by intensifying competition in global markets, most companies have been increasingly implementing supply chain management (SCM) and information systems (IS) practices. As well, globalization policies have created ...

  • APPLICATION OF PARTIAL DIFFERENTIAL EQUATIONS IN SNOW MECHANICS 

    Ahmadi, S. (Islamic Azad University, Central tehran Branch, 2011-01-01)
    In the present work, failure of a snow slab is analyzed by accounting Normal mode criteria. The analysis has been extended to include residual stress into the model (in addition to body forces). Intensity of crack energy ...

  • UNBOUNDEDNESS IN MOILP AND ITS EFFICIENT SOLUTIONS 

    Tohidi, G.؛ Razavyan, S. (Islamic Azad University, Central tehran Branch, 2011-01-01)
    In this paper we investigate Multi-Objective Integer Linear Programming (MOILP) problems with unbounded feasible region and introduce recession direction for MOILP problems. Then we present necessary and sufficient conditions ...

  • ON AN EXTENSION OF A QUADRATIC TRANSFORMATION FORMULA DUE TO GAUSS 

    Rakha, M. A.؛ Rathie, A. K.؛ Chopra, P. (Islamic Azad University, Central tehran Branch, 2011-01-01)
    The aim of this research note is to prove the following new transformation formula begin{equation*} (1-x)^{-2a},_{3}F_{2}left[begin{array}{ccccc} a, & a+frac{1}{2}, & d+1 & & & & & ; & -frac{4x}{(1-x)^{2}} & c+1, & d & ...

  • VARIATIONAL HOMOTOPY PERTURBATION METHOD FOR SOLVING THE NONLINEAR GAS DYNAMICS EQUATION 

    Matinfar, M.؛ Raeisi, Z. (Islamic Azad University, Central tehran Branch, 2011-01-01)
    A. Noor et al. [7] analyze a technique by combining the variational iteration method and the homotopy perturbation method which is called the variational homotopy perturbation method (VHPM) for solving higher dimensional ...

  • THE ROLE OF TREATMENT ON CONTROLLING CHANCROID PREVALENCE 

    Mushayabasa, S.؛ Bhunu, C. P. (Islamic Azad University, Central tehran Branch, 2011-01-01)
    Chancroid is a highly infectious and curable sexually transmitted disease caused by the bacterium Haemophilus Ducreyl (also known as H. Ducreyl). A deterministic mathematical model for investigating the role of treatment ...

  • INTERPOLATION BY HYPERBOLIC B-SPLINE FUNCTIONS 

    Amirfakhrian, M.؛ Nouriani, H. (Islamic Azad University, Central tehran Branch, 2011-01-01)
    In this paper we present a new kind of B-splines, called hyperbolic B-splines generated over the space spanned by hyperbolic functions and we use it to interpolate an arbitrary function on a set of points. Numerical tests ...
