Mathematical modeling and hybridized evolutionary LP local search method for lot-sizing with supplier selection, inventory shortage, and quantity discounts

•A multi-period lot-sizing problem with supplier selection and shortage is tackled.•A mixed integer non-linear programming (MINLP) model is developed.•A hybridized search Evolutionary LP-driven local search method is developed.•Overall results show superiority of developed hybridized search method.•...
