Inventory Replenishment Models are mathematical models used in business to determine a product’s optimal inventory level and order quantity. By crunching data like sales forecast, projected unit demand, transportation costs, reordering lead time, and more, these models help businesses find the most efficient way to replenish their inventory and minimize the losses associated with excessive or inadequate stock levels. This allows companies to improve their cash flow, increase customer satisfaction, and reduce waste. And all of this is possible without anyone ever having to lift a finger!
