    • Architecture framework for software safety 

      Gürbüz H.G.; Pala Er, N.; Tekinerdogan, B. (Springer Verlag, 2014)
      Currently, an increasing number of systems are controlled by soft- ware and rely on the correct operation of software. In this context, a safety- critical system is defined as a system in which malfunctioning software could ...
    • 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 ...
    • 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 ...
    • Reconfigurable hardened latch and flip-flop for FPGAs 

      Ahangari, H.; Alouani, I.; Ozturk, O.; Niar, S. (IEEE Computer Society, 2017)
      In this paper, we propose Joint Latch (JLatch) and Joint Flip-Flop (JFF), two novel reconfigurable structures which bring the reconfigurability of reliability to user latches and flip-flops (FFs) in reconfigurable devices ...
    • Scheduling in a three-machine flexible robotic cell 

      Gultekin H.; Akturk, M.S.; Karasan O.E. (2006)
      In this study, a three-machine flexible robotic manufacturing cell in which the CNC machines are used is considered. These machines are highly flexible and are capable of performing several different operations. Each machine ...
    • Scheduling with tool changes to minimize total completion time: a study of heuristics and their performance 

      Aktürk, M. S.; Ghosh, J. B.; Güneş, E. D. (John Wiley & Sons, Inc., 2003)
      The machine scheduling literature does not consider the issue of tool change. The parallel literature on tool management addresses this issue but assumes that the change is due only to part mix. In practice, however, a ...
    • Tool allocation and machining conditions optimization for CNC machines 

      Aktürk, M. S.; Avcı, S. (Elsevier, 1996)
      In the literature, there exist many variations of machining economics problem in terms of modelling approaches and solution methodologies. However most of the existing studies focus on the single machining operation which ...
    • Two-machine flowshop scheduling with flexible operations and controllable processing times 

      Uruk, Z.; Gultekin H.; Akturk, M. S. (2013)
      We consider a two-machine flowshop scheduling problem with identical jobs. Each of these jobs has three operations, where the first operation must be performed on the first machine, the second operation must be performed ...
