Sailco Corporation must determine how many sailboats should be produced during each of the next four quarters. The demand during each of the next four quarters is as follow: Sailco must meet demands on time. At the beginning of the first quarter, Sailco has an inventory of 10 sailboats. For simplicity, we assume that sailboats manufactured during a quarter can be used to meet demand for that quarter. During each quarter, Sailco can produce up to 40 sailboats with regular-time labor at a total cost of $400 per sailboat. By having employees work overtime during a quarter, Sailco can produce additional sailboats with overtime labor at a total coat of $450 per sailboat. At the end of each quarter, a carrying or holding cost of $20 per sailboat is incurred. The company needs to determine a production plan which minimizes the total production and inventory costs during the next four quarters. Solve the planning problem using What'sBest
