A manufacturing company is analyzing its production data to optimize its supply chain operations. They have collected historical data on production rates, inventory levels, and demand forecasts. The company wants to implement prescriptive analytics to determine the optimal inventory levels that minimize costs while meeting customer demand. If the cost of holding inventory is represented by the function \\( C_h = h \\cdot I \\), where \\( h \\) is the holding cost per unit and \\( I \\) is the inventory level, and the cost of stockouts is represented by \\( C_s = s \\cdot D \\), where \\( s \\) is the stockout cost per unit and \\( D \\) is the demand, how can the company effectively balance these costs to find the optimal inventory level?
