  • Solving a bi-objective project capital budgeting problem using a fuzzy multi-dimensional knapsack 

    Khalili-Damghani, A؛ Taghavifard, M (Islamic Azad University, South Tehran Branch, 2011-03-01)
    In this paper, the researchers have proposed a multi-dimensional knapsack model for project capital budgeting problem in uncertain situation which has been modeled through fuzzy sets. The optimistic and pessimistic situations ...

  • A neuro-fuzzy approach to vehicular traffic flow prediction for a metropolis in a developing country 

    Ogunwolu, L؛ Adedokun, O؛ Orimoloye, O؛ Oke, S.A (Islamic Azad University, South Tehran Branch, 2011-03-01)
    Short-term prediction of traffic flow is central to alleviating congestion and controlling the negative impacts of environmental pollution resulting from vehicle emissions on both inter- and intra-urban highways. The strong ...

  • Maintenance management decision model for preventive maintenance strategy on production equipment 

    Ahmad, R؛ Kamaruddin, S؛ Azid, I؛ Almanar, I (Islamic Azad University, South Tehran Branch, 2011-03-01)
    In industries, Preventive Maintenance (PM) is not a new practice to minimise the sudden breakdown of production machine. PM will be performed at predetermine intervals to provide a balance between failure cost and component ...

  • Flexible flowshop scheduling with equal number of unrelated parallel machines 

    Mahdavi, L؛ Zarezadeh, V؛ Shahnazari-Shahrezaei, P (Islamic Azad University, South Tehran Branch, 2011-03-01)
    This article addresses a multi-stage flowshop scheduling problem with equal number of unrelated parallel machines. The objective is to minimize the makespan for a given set of jobs in the system. This problem class is ...

  • A genetic algorithm approach for problem 

    Mehdizadeh, E؛ Tavakkoli-Moghaddam, R (Islamic Azad University, South Tehran Branch, 2011-03-01)
    In this paper, a genetic algorithm is presented for an identical parallel-machine scheduling problem with family setup time that minimizes the total weighted flow time ( ). No set-up is necessary between jobs belonging to ...

  • B2B electronic market analysis using game theory

    In the explosive growth of Business to Business (B2B) Electronic Trades, electronic markets have received a great deal of attention recently. The obtained profit of trading in E-B2B market encourage market participants to ...

  • A fuzzy random multi-objective approach for portfolio selection 

    Aryanezhad, M.B؛ Malekly, H؛ Karimi-Nasab, M (Islamic Azad University, South Tehran Branch, 2011-03-01)
    In this paper, the portfolio selection problem is considered, where fuzziness and randomness appear simultaneously in optimization process. Since return and dividend play an important role in such problems, a new model is ...

  • A new heuristic method based on CPM in SALBP 

    Fathi, M؛ Jahan, A؛ Ariffin, M.K؛ Ismail, N (Islamic Azad University, South Tehran Branch, 2011-03-01)
    The task of balancing of assembly lines is well-known in mass production system but this problem is NP-hard even for the simple straight line. Therefore, utilizing heuristic methods for these problems is totally unquestionable. ...
