Problem
Supply chain consultant Marissa Lopez and Sony are trying to determine the safety stock, Base Stock and Order Quantity for circuit cards. It takes 4 days for Sony to receive its cards, and Sony uses a review period of 11 days. Marissa estimates that the daily demand for Sony is 250 cards on average with a daily standard deviation of 49 units. After long conversations with the management team, Sony agrees to target a service level of 92%. Suppose that Sony observes that at the end of the review period, there are 745 units of its circuit cards left in inventory. What should be Sony's Order Quantity (use two decimal places in your answer)?
