Purpose: We aim to examine the capacitated multi-item lot sizing problem which is a typical example of a large bucket model, where many different items can be produced on the same machine in one time period. We propose a new approach to determine the production sequence and lot sizes that...

Lot sizing and scheduling problems arise when a variety of products are manufactured in a plant of finite capacity in which a single product variant at one time can be manufactured, and changeover costs (and/or times) depend on the products scheduling sequence. MIP models developed to solve...
