Operations Calculators — Business
Run the core inventory and operations models on real numbers. The EOQ calculator finds the order quantity that minimizes holding and ordering cost, the reorder point and safety stock tools set inventory triggers against demand variability, and the M/M/s queueing calculator estimates wait times and server needs. Each shows the operations-research formula, helping planners cut stockouts and overstock with defensible math.
