Show transcribed image text Gearbox Express in Mukwonago, Wl repairs gearboxes for wind turbines. The company works seven days per week and last week had the following new orders and end of day inventory levels. This company should be assumed to be operating at steady state so Little's Law can be applied. a) What is the average arrival of orders per day? b) What is the average ending on hand (inventory level) per day? c) Using Little's Law, how many hours on average did an order spend at Gearbox Express last week? Given these sales figures over the first 7 months of the year, your boss needs you to test two different forecasting methods (parts a and b below) to determine which method is best. For your measure of "best", recommend to your boss that the company should use the method with the lowest mean absolute deviation (MAD). Then use that method to provide your forecast for August in part c. a) Calculate the MAD for the 4 period moving average forecasting technique. b) Calculate the MAD for the 2 period weighted moving average forecasting technique. Use weights of 0.6 and 0.4, with the most recent observation weighted higher. c) How many units would you forecast will be sold in August?
