  • EPQ model with depreciation cost and process quality cost as continuous functions of time 

    Afshar Nadjafi, B؛ Abbasi, B (Islamic Azad University, South Tehran Branch, 2009-06-01)
    Extensive research has been devoted to economic production quantity (EPQ) problem. However, little atten-tion has been paid to problems where depreciation cost and process quality cost must be considered, simulta-neously. ...

  • The optimal number of yard cranes in container terminal 

    Amin, GH.R؛ Golchubian, H (Islamic Azad University, South Tehran Branch, 2009-06-01)
    The aim of this study is to propose a new mixed integer linear programming (MILP) model to find the minimum required number of yard cranes, Rubber tyred gantry cranes (RTGCs), for completion the total amount of works at ...

  • A weighted metric method to optimize multi-response robust problems 

    Noorossana, R؛ Kamali Ardakani, M (Islamic Azad University, South Tehran Branch, 2009-06-01)
    In a robust parameter design (RPD) problem, the experimenter is interested to determine the values of con-trol factors such that responses will be robust or insensitive to variability of the noise factors. Response sur-face ...

  • Flexible job shop scheduling under availability constraints 

    Taghavi-Fard, M.T؛ Dehnar Saidy, H.R (Islamic Azad University, South Tehran Branch, 2009-06-01)
    In this paper, an exact geometric algorithm is presented for solving two-job sequencing and scheduling problems in flexible flow shop and job shop environments while the resources are (un)available in some time periods and ...

  • Multi-factor failure mode critically analysis using TOPSIS 

    Sachdeva, a؛ Kumar, D؛ Kumar, P (Islamic Azad University, South Tehran Branch, 2009-06-01)
    The paper presents a multi-factor decision-making approach for prioritizing failure modes as an alternative to traditional approach of failure mode and effect analysis (FMEA). The approach is based on the ‘technique for ...

  • Solving the tandem AGV network design problem using tabu search: Cases of maximum workload and workload balance with fixed and non-fixed number of loops 

    Miandoabchi, E؛ Zanjirani Farahani, R (Islamic Azad University, South Tehran Branch, 2009-06-01)
    A tandem AGV configuration connects all cells of a manufacturing area by means of non-overlapping, sin-gle-vehicle closed loops. Each loop has at least one additional P/D station, provided as an interface between adjacent ...

  • Study on implementation of one-piece lean line design using simulation techniques: A practical approach 

    Ramesh, V؛ Sreenivasa Prasad, K.V؛ Srinivas, T.R (Islamic Azad University, South Tehran Branch, 2009-06-01)
    This paper discusses the simulation study carried out for proposing one-piece lean line layout with features of Lean Manufacturing. The lean initiatives that can be addressed are, introducing Kanban replenishment sys-tem, ...

  • Policy options for value added to different levels of production 

    Anyaeche, C.O (Islamic Azad University, South Tehran Branch, 2009-06-01)
    This paper presents an analytic procedure for the value added to different production levels with different policy options. The approach is stochastic and thus provides a framework for informed decision-making on productivity ...
