Inventory model for multi-perishable goods with limited storage capacity

Abstract

The warehouse has an important role, namely storing finished products as well as semi-finished, especially in the Agrifood Supply Chain (ASC) which has special characteristics such as limited shelf life, changing variations in demand and prices that can be adjusted to make ASC look more complex and more difficult than other supply chains. In this study, various thoughts are offered to fit the real conditions. Stochastic demand distribution, the presence of constant lead time on each product, exponential decay rates, to limited storage space capacity. Related to this assumption, the ongoing review (Q, r) is aimed at supply policies that are relevant to the agricultural-food supply chain problem. The development of a mathematical model with decision variables Q and r to minimize costs on warehouse procurement is then analyzed using a comparison using parameter ordering costs, storage costs, and shortage costs that have been determined in this study. on items with limited warehouse capacity. In previous research, the process of storing and procuring multi-products did not contain short-lived products. Also, other studies also explain the storage of products in a short shelf life does not contain a shortage of limited storage capacity. It can be done on research that will be carried out adjusted to conditions that occur in the real world It is estimated that it will make a practical contribution and be a reference model of inventory policies for warehouses that have relevant requirements.
