  • Evaluation of the efficiency by DEA a case study of hospital 

    Ghaziyani, Kh.؛ Ejlaly, B.؛ Bagheri, S. F. (Ayandegan Institute of Higher Education, Iran, 2019-09-01)
    Data Envelopment Analysis (DEA) is a nonparametric technique used to determine the relative efficiency of Decision Making Units (DMUs). Results from DEA analysis yield important information regarding the optimal operating ...

  • A signed distance method for solving multi-objective transportation problems in fuzzy environment 

    Abd El-Wahed Khalifa, H. (Ayandegan Institute of Higher Education, Iran, 2019-09-01)
    This paper aims to study the multi-objective transportation problem with fuzzy parameters. These fuzzy parameters represented as (α, β) interval-valued fuzzy numbers instead of the normal fuzzy numbers. Using the signed ...

  • A framework to evaluate and improve supply chain: FAHP based case study on a supermarket 

    Haldar, Sh.؛ Karmaker, Ch.؛ Hossain, Sk. (Ayandegan Institute of Higher Education, Iran, 2019-09-01)
    Nowadays, the supply chain has become a buzzword in the business field. Only the supply chain can help to lead a business in an organized way. However, in a supermarket, the supply chain is very important, but it needs to ...

  • An optimization model for cold chain food distribution 

    Garside, A. K. (Ayandegan Institute of Higher Education, Iran, 2019-09-01)
    Food product has a characteristic of continuous quality deterioration until the food is consumed. Cold chain distribution can improve the sustainability of the product quality but requires a more significant investment for ...

  • Some fixed point results involving a general LW-type cyclic mapping in complete b-metric-like spaces 

    Weng, S. Q. (Ayandegan Institute of Higher Education, Iran, 2019-09-01)
    In recent years, the research of the fixed point theorem is a hot topic all the time. In this paper, we propose the notion of new mapping, that is, a general LW-type cyclic mapping, in a complete b-metric-like spaces. Then, ...

  • Calculation of fuzzy matrices determinant 

    Babakordi, F.؛ Taghi-Nezhad, N. A. (Ayandegan Institute of Higher Education, Iran, 2019-09-01)
    Matrix and its determinant are two basic tools, which are important in financial, accounting, and economic affairs. Therefore, in this paper, a simple and effective method is proposed to obtain the determinant of fuzzy ...

  • An optimization model for aggregate production planning and control: a genetic algorithm approach 

    Ahmed, S. M.؛ Biswas, T. K.؛ Nundy, C. K. (Ayandegan Institute of Higher Education, Iran, 2019-09-01)
    In this paper, an optimization model for aggregate planning of multi-product and multi-period production system has been formulated. Due to the involvement of too many stakeholders as well as uncertainties, the aggregate ...
