Smart Inventory: Reorder Point & Safety Stock

Interactive 3D simulation of a smart inventory management system: watch a warehouse stock level rise and fall against random daily demand, trigger reorders at the reorder point, and see how safety stock trades holding cost against stockout risk.

Every smart inventory management system is, underneath the dashboards, running the same trade-off: order too little safety stock and a random demand spike causes a stockout; carry too much and holding cost quietly eats the margin. This simulation runs a warehouse's (s, Q) reorder policy live — daily demand draws down a stock column, a reorder fires automatically when the reorder point is crossed, and a delivery arrives after the supplier's lead time. Adjust demand variability, the reorder point, order quantity and lead time to see how each pulls the balance between holding cost and stockout risk.
