Abstract

This study develops a comprehensive inventory model for deteriorating items by incorporating realistic market and sustainability factors, including stock-level and selling price-dependent demand, preservation technology, green technology investment, and partial backlogging. The model captures the inverse relationship between selling price and demand while also considering that higher stock levels can positively influence customer perception, enhancing demand. To counteract deterioration and environmental impact, the model integrates preservation technology and green technology initiatives that reduce product decay and carbon emissions, respectively. Partial backlogging is allowed, assuming that only a fraction of unsatisfied demand during stockouts is backordered based on waiting time. The objective is to minimize the total inventory cost, including holding, preservation, green investment, deterioration, and shortage costs. Analytical and numerical approaches are employed to determine optimal replenishment policies under varying parameter settings. The results demonstrate the effectiveness of combining sustainability practices with advanced inventory strategies to improve both economic and environmental performance. Sensitivity analysis further illustrates how preservation efforts and green investment significantly influence system efficiency and cost minimization.
