The primary goal of inventory management is to ensure that supply meets demand without leading to oversupply or stockouts. Effective inventory control optimizes resources and minimizes costs.
ABC Analysis categorizes inventory into three classes (A, B, and C) based on importance and value, allowing managers to focus on items that have the greatest impact on overall inventory cost.
Recruitment costs are unrelated to inventory holding. Holding costs typically include expenses like storage, insurance, and spoilage loss associated with maintaining inventory.
In a fixed-order quantity system, orders are placed when inventory levels drop to a predetermined reorder point to ensure supply meets demand without delay.
Lead time is the duration from placing an order to receiving it, including processing and transport time. Accurate lead time estimates help prevent inventory shortages.
Buffer stock refers to additional inventory maintained to meet unexpected demand spikes, ensuring that supply remains consistent despite variability.
The just-in-time inventory system reduces carrying costs by receiving goods only as they are needed for production, minimizing storage expenses and waste.
EOQ, or Economic Order Quantity, is a principle used to determine the optimal order quantity that minimizes total inventory costs such as holding and ordering costs.
Inventory turnover analysis helps identify fast-moving products and reduce the cash tied up in holding surplus stock, thus improving cash flow and operational efficiency.
Cycle counting is a method of internal inventory control where inventory subsets are regularly counted and verified, helping maintain accurate stock records without annual full counts.
