An optimization approach for brass casting blending problem under aletory and epistemic uncertainties

SakallI, Ümit Sami; Baykoç, Ömer Faruk - In: International Journal of Production Economics 133 (2011) 2, pp. 708-718

A critical process in brass casting is the determination of the materials and their quantities to be added into the blend. The reason of being critical is the uncertainty about metal percentages in scrap raw materials. In this paper, the aleatory and epistemic uncertainties, which are modeled by...
