This paper focuses on an industrial lot-sizing and scheduling problem that arises in the food industry includes lost sales, overtimes sequence-dependent setups parallel machines. We propose a preliminary version of three-phase iterative approach to optimize separately affectation, sequencing production items. Our first numerical results suggest with some additional improvements, this could be u...

The Capacitated Lot-Sizing Problem (CLSP) and its variants are important challenging optimization problems. Constructive heuristics known to be the most intuitive fastest methods for finding good feasible solutions CLSPs therefore often used as a subroutine in building more sophisticated exact or metaheuristic approaches. Classical constructive heuristics, such period-by-period lot elimination ...
