O’Neill uses A/F ratios to measure the quality of their forecasting of seasonal items. They use the newsvendor model to choose order quantities. O’Neill improves its forecasting with time. After several seasons of implementing this process which of the following should O’Neill observe: A)The average A/F ratio should get closer to the average critical ratio of the products. B)The average A/F ratio should get closer to the target fill rate (which is the same across all products). C)The average A/F ratio should get closer to the stock-out probability (which is the same across all products). D)The standard deviation of the A/F ratios should get closer to 1. E)The maximum A/F ratio should decrease and/or the minimum A/F ratio should increase. F)None of the above.
