Abstract


Due to their importance in industry, dynamic demand lot-sizing problems are frequently studied.
This study consider dynamic lot-sizing problems with recent advances in problem and model
formulation, and algorithms that enable large-scale problems to be effectively solved.
Comprehensive review is given on model formulation of dynamic lot-sizing problems, especially
on capacitated lot-sizing (CLS) problem and the coordinated lot-sizing problem. Both
approaches have their intercorrelated, where CLS can be employed for single or multi
level/stage, item, and some restrictions. When a need for joint setup replenishment exists, then
the coordinated lot-sizing is the choice. Furthermore, both algorithmics and heuristics solution
in the research of dynamic lot sizing are considered, followed by an illustration to provide an
efficient algorithm.
