Demand for a power steering gear assembly is given by Period 1 2 3 4 5 6 7 8 9 10 Gear 14 12 12 13 5 90 20 20 20 20 Currently there are 50 parts on hand. The lot-sizing rule is, again, fixed order period using two periods. Lead time is three periods. Determine the planned order release schedule for the gear.   Suppose each gear assembly requires two pinions. Currently there are 100 pinions on hand, the lot-sizing rule is lot-for-lot, and the lead time is one period. Determine the gross requirement and then the planned order release schedule for pinions.

The MRP gross requirements for Item X are shown here for the next 10 weeks. Lead time for A is two weeks, and setup cost is $10. There is a carrying cost of $0.02 per unit per week. Beginning inventory is 72 units.

Exercise 2: The demand per year (D) for product X is 12,100 units. The costs of placing an order (S) are $4.50. The unit cost (C) of the item is $25.00. The maintenance cost (H) per unit per year is 30% of the item's cost. 1. Use the economic order quantity (EOQ) model to determine: *Optimal quantity to order* The expected number of orders*Optimal time between orders*The total annual cost of maintaining that optimal amountNOTE: Show calculations of how you arrived at each amount 2. Answer, what are the potential benefits of using EOQ analysis for inventory management? How can you help businesses strike a balance between inventory holding costs and ordering costs?
