Inventory control

Inventory control techniques include ABC analysis, economic order quantity (EOQ), perpetual inventory system, review of slow and non-moving items, input-output ratio analysis, and setting various inventory levels. EOQ determines the optimal order quantity to minimize total inventory costs. Perpetual inventory involves continuously updating inventory records as items are received or used to prevent closing down for stocktaking. Input-output ratio analysis examines the relationship between raw materials used and final outputs. Setting inventory levels such as maximum, minimum, reorder helps maintain appropriate stock levels.
