Develop a solution with PPB Lot-Sizing technique and calculate the total relevant costs for the gross requirements in the following table*. Period 1 2 3 4 5 6 7 8 9 10 11 12 Gross requirements 20 40 40 70 30 10 80 40 *Holding cost = $2.50/unit/week; setup cost = $150; lead time = 1 week; beginning inventory = 40. Develop a PPB solution (enter your responses as whole numbers).
