A New Formulation for the Capacitated Lot Sizing Problem with Batch Ordering Allowing Shortages
Mathematics, 2020 This paper addresses the multi-product, multi-period capacitated lot sizing problem. In particular, this work determines the optimal lot size allowing for shortages (imposed by budget restrictions), but with a penalty cost.
