Final answer:
The optimal stocking level in the single-period model is determined by balancing the costs of overstocking with the costs of understocking, considering factors like demand forecasts, product costs, and selling prices to maximize profit or minimize costs.
Step-by-step explanation:
In the single-period model, the key to determining the optimal stocking level is to balance the cost of understocking against the cost of overstocking.
The model seeks to minimize potential losses due to unsold inventory (overstock) while also avoiding lost sales opportunities due to insufficient inventory (understock). To find the optimal stocking quantity, a business must consider the cost of ordering too many items (which can lead to markdowns or spoilage) versus the profit lost when items are out of stock.
This involves calculating the service level, and the probability of not running out of stock, which is based on the forecasted demand and the product's cost and selling price. By considering these factors, businesses can set a stock level that maximizes expected profit or minimizes expected costs.
