Mathematical modeling of inventory dynamics in a two-level supply chain with freshness constraints
Resumen
This paper explores the inventory dynamics of a two-level supply chain, where distribution centers supply fresh products to supermarkets while considering the impact of freshness degradation. We develop a mathematical model to analyze the inventory levels of a product at a distribution center over a supply interval, incorporating the coefficient of freshness decay, $\theta$. The study derives equations governing inventory changes, initial stock levels, and replenishment quantities. The results indicate how freshness degradation influences inventory replenishment requirements, helping optimize stock levels at supermarkets. A graphical analysis further illustrates the impact of key parameters on inventory management and profit margins.
