Consider the case when Sony uses a Periodic Review Policy (I, S). Sony plans to order from its supplier once in fourteen business days, corresponding to a Review Period of I = 14 business days. The supplier delivers each order in a lead-time of 6 business days. Sony has an expected (average) daily demand of 150 units with a standard deviation (of daily demand) of 30 units. The management team at Sony continues to target a 93% service level. What is the appropriate safety stock (SS) ? Given the appropriate safety stock (SS) and the same information as in question 4, what is the appropriate base stock (S)? (Considering your answers to questions 4 and 5) What happens to SS and S (increase or decrease) if the service level is increased from 93% to 95%? Given all information from question 4,5, and 6, if Sony has 220 cards leftover in inventory at the end of a review period, how much should it order from its supplier to have a 93% service level? Given all information from question 4,5,6. If Sony has 220 cards leftover in inventory at the end of a review period, how much should it order from its supplier to have a 95% service level?
