I am looking to optimise the blending of different types of coal for the coke making process of a steel plant. I want to take into account the statistical variation of each coal’s qualities, so for this reason I looked at a chance constrained model. I also want to have multiple objectives, one to minimise cost and another to maximise yield, and possibly a third to maximise coke quality. So I have thought about doing a chance constrained multiple objective model, but I am not very experienced in this area. Is there any advice or recommendations for literature to read about this problem? Thank you in advance!
