This paper deals with the single-item capacitated lot sizing problem with concave production and storage costs, and minimum order quantity (CLSP-MOQ). In this problem, a demand must be satisfied at each period t over a planning horizon of T periods. This demand can be satisfied from the stock or...

Defining an efficient bill of materials for a family of complex products is a real challenge for companies, largely because of the diversity they offer to consumers. To remain competitive, their products are available with many variants and options, which leads to a difficult question: "How can...

This paper introduces new environmental constraints, namely carbon emission constraints, in multi-sourcing lot-sizing problems. These constraints aim at limiting the carbon emission per unit of product supplied with different modes. A mode corresponds to the combination of a production facility...
