- 1. Inventory theory is a fundamental concept in supply chain management that deals with the optimization of inventory levels within an organization. The main objective of inventory theory is to strike a balance between meeting customer demand and minimizing the costs associated with holding excess inventory. By carefully managing inventory levels, businesses can ensure timely fulfillment of customer orders while simultaneously reducing carrying costs and avoiding stockouts. Inventory theory involves various models and techniques, such as economic order quantity (EOQ), just-in-time (JIT) inventory systems, and safety stock analysis, to effectively manage the flow of goods and materials through the supply chain. Through the application of inventory theory, organizations can improve operational efficiency, enhance customer satisfaction, and ultimately achieve a competitive advantage in the marketplace.
