    • A beam search-based algorithm and evaluation of scheduling approaches for fexible manufacturing systems 

      Sabuncuoglu İ.; Karabuk, S. (Taylor & Francis, 1998)
      This paper presents a new algorithm for the flexible manufacturing system (FMS) scheduling problem. The proposed algorithm is a heuristic based on filtered beam search. It considers finite buffer capacity, routing and ...

    • Binary integer formulation for mixed-model assembly line balancing problem 

      Gökçen, H.; Erel, E. (Pergamon Press, 1998-04-01)
      The assembly line balancing problem has been a focus of interest to the academicians of production/operations management for the last 40 years. Although there are numerous studies published on the various aspects of the ...

    • Economic design of EWMA control charts based on loss function 

      Serel, D. A. (Elsevier, 2009)
      For monitoring the stability of a process, various control charts based on exponentially weighted moving average (EWMA) statistics have been proposed in the literature. We study the economic design of EWMA-based mean and ...

    • Generalizing predicates with string arguments 

      Cicekli, I.; Cicekli, N. K. (Springer New York LLC, 2006-06)
      The least general generalization (LGG) of strings may cause an over-generalization in the generalization process of the clauses of predicates with string arguments. We propose a specific generalization (SG) for strings to ...

    • An integrated process planning approach for CNC machine tools 

      Aktürk, M. S.; Avcı, S. (Springer-Verlag, 1996)
      In view of the high investment and tooling cost of a CNC machining centre, the cutting and idle times should be optimised by considering the tool consumption and the non-machining time cost components. In this paper, we ...

    • Integrated scheduling and tool management in flexible manufacturing systems 

      Aktürk, M. S.; Özkan, S. (Taylor & Francis, 2001)
      A multistage algorithm is proposed that will solve the scheduling problem in a flexible manufacturing system by considering the interrelated subproblems of processing time control, tool allocation and machining conditions ...

    • Joint lot sizing and tool management in a CNC environment 

      Aktuük, M. S.; Önen, S. (Elsevier, 1999)
      We propose a new algorithm to solve lot sizing, tool allocation and machining conditions optimization problems simultaneously to minimize total production cost in a CNC environment. Most of the existing lot sizing and tool ...

    • Match-up scheduling under a machine breakdown 

      Aktürk, M. S.; Görgülü, E. (Elsevier, 1999)
      When a machine breakdown forces a modified flow shop (MFS) out of the prescribed state, the proposed strategy reschedules part of the initial schedule to match up with the preschedule at some point. The objective is to ...

    • Optimal timing of project control points 

      Raz, T.; Erel, E. (Elsevier, 2000)
      The project control cycle consists of measuring the status of the project, comparing to the plan, analysis of the deviations, and implementing any appropriate corrective actions. We present an analytical framework for ...

    • A simulation based learning meachanism for scheduling systems with continuous control and update structure 

      Metan, G.; Sabuncuoğlu, İhsan (IEEE, 2005)
      A simulation based learning mechanism is proposed in this study. The system learns in the manufacturing environment by constructing a learning tree and selects a dispatching rule from the tree for each scheduling period. ...
