  • Supplier selection in the sustainable supply chain: The application of analytic hierarchy process and fuzzy data envelopment analysis 

    Rezaei, Hamid Reza؛ Taleghani, Mohammad؛ Shafieyan, Mohsen؛ Nikandam, Tara (Islamic Azad University, Rasht Branchدانشگاه آزاد اسلامی واحد رشت, 2019-06-01)
    The development and management of an effective and efficient supply chain involve the selection of the suppliers. Only economic criteria, including cost and delivery, once used to be considered in the process of supplier ...

  • A study of Financing Decisions and Capital Structure in Real Investment 

    Aghajan Nashtaei, Reza؛ Chirani, Ebrahim؛ GoudarzvandChegini, Mehrdad (Islamic Azad University, Rasht Branchدانشگاه آزاد اسلامی واحد رشت, 2019-06-01)
    In real investment, there is a relationship between external financing and abnormal stock returns. This study predicts a negative correlation between external financing and stock returns. The dependent variable of the ...

  • Forecast of climatologically events using improved grey model (Case Study: Qazvin Province Climatology) 

    Karimi Khajehghiasi, Maryam؛ Alinezhad, Alireza (Islamic Azad University, Rasht Branchدانشگاه آزاد اسلامی واحد رشت, 2019-06-01)
    The theory of grey system is used when sufficient information of the community under study is not in hand. The grey forecast model is proper when the information variety is fix and certain. Grey model can apply some ...

  • A New Approach for Solving Interval Quadratic Programming Problem 

    Taghi-Nezhad, N. A.؛ Taleshian, Fatemeh؛ Shahini, M. (Islamic Azad University, Rasht Branchدانشگاه آزاد اسلامی واحد رشت, 2019-06-01)
    This paper discusses an Interval Quadratic Programming (IQP) problem, where the constraints coefficients and the right-hand sides are represented by interval data. First, the focus is on a common method for solving Interval ...

  • An efficient technique for solving systems of integral equations 

    Ebrahimi, Hamideh (Islamic Azad University, Rasht Branchدانشگاه آزاد اسلامی واحد رشت, 2019-06-01)
    In this paper, the wavelet method based on the Chebyshev polynomials of the second kind is introduced and used to solve systems of integral equations. Operational matrices of integration, product, and derivative are obtained ...

  • Comparative Study of Particle Swarm Optimization and Genetic Algorithm Applied for Noisy Non-Linear Optimization Problems 

    Towsyfyan, Hossein؛ Kolahdooz, Amin؛ Esmaeel, Hazem؛ Mohammadi, Shahed (Islamic Azad University, Rasht Branchدانشگاه آزاد اسلامی واحد رشت, 2019-06-01)
    Optimization of noisy non-linear problems plays a key role in engineering and design problems. These optimization problems can't be solved effectively by using conventional optimization methods. However, metaheuristic ...

  • A Recurrent Neural Network Model for solving CCR Model in Data Envelopment Analysis 

    Abbasi, Masomeh؛ Ghomashi, Abbas (Islamic Azad University, Rasht Branchدانشگاه آزاد اسلامی واحد رشت, 2019-06-01)
    In this paper, we present a recurrent neural network model for solving CCR Model in Data Envelopment Analysis (DEA). The proposed neural network model is derived from an unconstrained minimization problem. In the theoretical ...

  • Optimization of solution stiff differential equations using MHAM and RSK methods 

    Sadigh Behzadi, Shadan (Islamic Azad University, Rasht Branchدانشگاه آزاد اسلامی واحد رشت, 2019-06-01)
    In this paper, a nonlinear stiff differential equation is solved by using the Rosenbrock iterative method, modified homotpy analysis method and power series method. The approximate solution of this equation is calculated ...
