Makine çizelgeleme problemlerinde tüm makineler daima kullanılabilir durumda değildirler. Planlı bakım, öğle yemeği ve dinlenme molaları gibi nedenlerle periyodik olarak kesintilere uğrayabilmektedirler. Ancak literatürde genellikle bu durum göz ardı edilmektedir. Bu çalışmada kullanılamayan zaman dilimlerinin sıra bağımlı hazırlık sürelerinin olduğu ilişkisiz paralel makine problemi ele alınmı...

This paper considers the hybrid flow shop scheduling problem with two types of sequence-dependent setup times, one depending on order jobs and other both machines where are allocated. Three constructive heuristic algorithms based NEH algorithm developed object minimizing total energy consumption cost. The first algorithm, called EPRA, obtains using cost processing time. second ESRA, third ESPRA...

Minimizing the total completion time (TCT) is essential in numerous manufacturing settings. Since such a problem considered NP-hard, it not likely that an optimal solution exists. Accordingly, many papers scheduling literature look for dominance relation as to minimizing TCT. Furthermore, due wide range of unpredictability settings, consider settings with uncertain and bounded setup times. None...
