A Comparative Study of Extended Inventory Management in Two-Warehouse System

Abstract

Modern inventory management, environmental concerns, and supply chain management challenges have made the two-warehouse system a necessary and strategic approach. Early studies explored demand patterns, this system increases flexibility, reduces risk, and improves efficiency, while also facilitating the implementation of modern strategies such as green sustainability practices, the use of renewable resources, preservation technologies, and carbon-efficient supply chain management. Studies began with exploring demand patterns, backlogging, LIFO and FIFO dispatching systems, trade credit financing, and various modelling methods related to product deterioration over time. More recent research has incorporated factors aimed at improving ecological performance, such as reverse logistics, carbon emission control, sustainable transportation, preservation methods, and green technologies. This review paper emphasizes the urgent need to optimize sustainable two-warehouse inventory models within an economically beneficial, sustainable, smart, and climate-resilient framework, and to integrate preservation and green technologies, carbon emission regulations, and multi-echelon supply chain frameworks into future research and practice.
