Abstract

Perishability is an important phenomenon that has a widespread impact on food industries. Although perishability has received much recent attention in the literature, research incorporating perishability into mathematical models for the simultaneous lot sizing and scheduling problems is relatively rare. In this article, we review the literature discussing the integration of perishability into lot sizing and scheduling models. We describe key characteristics of lot sizing and scheduling problems, give a review of single-level lot sizing and scheduling problems, and discuss how perishability can be incorporated, reflecting the complexity of the problems proposed in the literature. We conclude the article by suggesting some directions for future research.
