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 6 7 8 9 10 11 12 Gross requirements 20 40 40 60 30 10 80 50 *Holding cost = $2.50/unit/week; setup cost = $200; lead time = 1 week; beginning inventory = 40. Develop a PPB solution (enter your responses as whole numbers). Period 1 2 3 4 6 7 8 9 10 11 12 |5| 20 40 40 60 30 10 80 50 40 Gross requirements On-hand at beginning of period On-hand at end of period Order receipt Order release The total cost is $ (enter your response as a whole number)
