please answer question 7

In some nuts and crackers store, let the demand for nuts be tons per month with a standard deviation of 2 tons. The holding cost is $20 per ton per year and the ordering cost is $80. The lead-time is 2months. Under the assumption of normal distribution of the demand, 1. Find the EOQ of this inventory. 2. If a periodic review system is employed, use EOQ to find the best review period. 3. Find the target level if zero safety stock is used. 4. Find the target level at a service level of 73%. 5. If the demand standard deviation per month changes to 4, what is the new Target at 73% service level. 6. Sketch the normal distribution of the demand during the protection period for both lead times (2 and 4 months) on the same diagram and show both Targets. Let the demand (i.e., X-axis) be between 0-80 tons. 7. If the demand over the next year is found to be as follows, establish a table for periodic review that shows the OH, SR, IP for the 12 months. Currently there are no schedules receipts. Use a target level of 42 and assume that the review start at month 3.: Assume OH is Month Review times Demand(tons) zero at the 1 beginning and 2 consider a review 3 Begin review here period of 4 months. 5 3 5 5 8 8 4 4 5 6 7 8 9 10 11 12 6 6 8 9 4 In some nuts and crackers store, let the demand for nuts be tons per month with a standard deviation of 2 tons.
