Discrete multi-module capacitated lot-sizing problems with multiple items

We study single-item discrete multi-module capacitated lot-sizing problems without and with backlogging where the amount produced in each time period is equal to the summation of binary multiples of the capacities of n available different modules (or machines). For fixed n≥2, we develop fixed-parame...

Abstract We study single-item discrete multi-module capacitated lot-sizing problems without and with backlogging where the amount produced in each time period is equal to the summation of binary multiples of the capacities of n available different modules (or machines). For fixed n≥2, we develop fixed-parameter tractable (polynomial) exact algorithms that generalize the algorithms of van Vyve (2007) for n=1. We utilize these algorithms within a Lagrangian decomposition framework to solve their multi-item versions. Our algorithms are computationally efficient and stable, in comparison to Gurobi 9.0.
