A successful trader must have a sophisticated inventory management system and be concerned about optimal stock levels. A quality inventory management model is necessary to make a profit while satisfying customer demand. Optimal inventory levels ensure the continuous functioning of the system with the lowest procurement and storage costs. Different inventory management models have their advantages and disadvantages, so it is crucial to plan in advance which model fits the company's needs. An additional challenge is posed by goods with a limited shelf life (fruit, newspapers, clothing). Consumers are increasingly less tolerant of shortages and will not hesitate to turn to the competition if they cannot find the desired product in perfect condition. Consequently, companies selling goods with a limited shelf life need to maintain sufficient stock to meet customer demand while keeping a minimum number of products in stock after the selling season. For companies, this means that they need to carefully estimate the optimal amount of inventory to hold for their products. One of the models that can be used to determine optimal inventory levels for products with limited shelf life is the newsvendor model, which is one of the most popular analytical models in decision science and operations management.
