In this article I show a firefly optimization based algorithm which helps to choose the appropriate suppliers in a case of given order quantity of a given product. The developed algorithm takes account of the minimum and maximum order quantities at the different suppliers as constraints. It also...

The study describes the simulation testing conducted in connection with the expansion of the department of Audi Hungaria Motor Ltd. for manufacturing small-scale bodyworks, during which the future operation of an extremely complex manufacturing system was modelled. The reason for demand of...
