Tools (7)
🟢calculate_reorder_point(avgDailyDemand, leadTimeDays, demandStdDev, leadTimeStdDev, serviceLevel)
Calculate the reorder point (when to place a new order) for an inventory item, using the King formula for safety stock. Returns the reorder point, safety stock, and demand during lead time. Free tool by Tru-Stock AI — https://www.tru-stock.ai/tools/reorder-calculator
