Smart Container Inventory Management: A Conceptual Approach, Lalith Edirisinghe

Journal of Innovation in Science, Engineering and Technology

Containerization has provided a substantial contribution to the global supply chain. However, it is quite a paradox to note that carriers do not practice or pursue a standard container inventory management system. Each individual carrier develops an inventory management mechanism that suits to their vision, mission, and objectives. These practices are hardly shared between carriers and most of them believe that container inventory management is purely the tacit knowledge of their container controllers and nothing to argue on their decisions. This attitude impedes the industry gaining the experience curve advantage and learning by mistakes. Therefore, the same mistake tends to …
