REVIEW OF RELATED LITERATURE
INVENTORY MANAGEMENT
Inventory management is a critical component of supply chain operations, encompassing the systematic process of ordering, storing, tracking, and controlling inventory to ensure that the right quantity of products is available at the right time and place. Effective inventory management balances the costs associated with holding inventory against the need to meet customer demand, thereby optimizing operational efficiency and profitability. (Ivanov et al., 2023).
Fundamental Concepts
At its core, inventory management involves several key principles
Inventory Control: Maintaining optimal stock levels to prevent overstocking or stockouts.
Demand Forecasting: Predicting future customer demand to inform inventory decisions.
Reorder Point and Safety Stock: Determining when to reorder stock and how much buffer inventory to maintain to mitigate uncertainties.
Inventory Turnover Ratio: Measuring how often inventory is sold and replaced over a period, indicating the efficiency of inventory management.
Advertisements
These principles are applied through various models and systems, such as Economic Order Quantity (EOQ), Just-In-Time (JIT), and Material Requirements Planning (MRP), each tailored to specific operational contexts. (Chopra & Meindl, 2022).
Technological Advancements
Recent years have witnessed significant technological advancements in inventory management:
Automation and AI: The integration of automation and artificial intelligence (AI) has revolutionized inventory processes. AI-powered systems can analyze historical data to forecast demand, optimize stock levels, and automate replenishment, reducing manual errors and improving efficiency. (Disney et al., 2023).
Real-Time Data Analytics: The use of real-time data analytics enables businesses to monitor inventory levels continuously, respond swiftly to demand fluctuations, and make informed decisions.
Blockchain Technology: Blockchain offers enhanced transparency and security in inventory management by providing immutable records of transactions, improving traceability, and reducing fraud.
Internet of Things (IoT): IoT devices facilitate real-time tracking of inventory, providing detailed information on location, condition, and movement, thereby enhancing visibility across the supply chain.
