MODELS and METHODS for LOT SIZING and SCHEDULING

The intent of this extended abstract is to briefly describe the work developed by the PhD student Carina Pimentel during her PhD studies, since 2007 until now. The core subject of this work is the development of models and methods for solving medium/short term production planning problems. Two different problems are studied. The first one is a classical lot sizing problem. For this problem several exact approaches were developed and compared. The second problem, motivated by a real situation, is a lot splitting and scheduling problem. For the latter, a new mixed integer programming model is developed, as well as several heuristic approaches that efficiently solve it.
