  • Multi-start simulated annealing for dynamic plant layout problem 

    Ashtiani, B؛ Aryanezhad, M.B؛ Farhang Moghaddam, B (Islamic Azad University, South Tehran Branch, 2007-04-01)
    In today's dynamic market, organizations must be adaptive to market fluctuations. In addition, studies show that material-handling cost makes up between 20 and 50 percent of the total operating cost. Therefore, this paper ...

  • The trim loss concentration in one-dimensional cutting stock problem (1D-CSP) by defining a virtual cost 

    Javanshir, H؛ Shadalooee, M (Islamic Azad University, South Tehran Branch, 2007-04-01)
    Nowadays, One-Dimensional Cutting Stock Problem (1D-CSP) is used in many industrial processes and re-cently has been considered as one of the most important research topic. In this paper, a metaheuristic algo-rithm based ...

  • On the multivariate variation control chart 

    Noorossana, R؛ Seyedaliakbar, S.M (Islamic Azad University, South Tehran Branch, 2007-04-01)
    Multivariate control charts such as Hotelling`s T^ 2 and X^ 2 are commonly used for monitoring several related quality characteristics. These control charts use correlation structure that exists between quality characteristics ...

  • Two optimal algorithms for finding bi-directional shortest path design problem in a block layout 

    Hamzeei, M؛ Zanjirani Farahani, R (Islamic Azad University, South Tehran Branch, 2007-04-01)
    In this paper, Shortest Path Design Problem (SPDP) in which the path is incident to all cells is considered. The bi-directional path is one of the known types of configuration of networks for Automated Guided Vehi-cles ...

  • An optimization technique for vendor selection with quantity discounts using Genetic Algorithm 

    Arunkumar, N؛ Karunamoorthy, L؛ Uma Makeshwaraa, N (Islamic Azad University, South Tehran Branch, 2007-04-01)
    Vendor selection decisions are complicated by the fact that various conflicting multi-objective factors must be considered in the decision making process. The problem of vendor selection becomes still more compli-cated ...
