Part (A)
To control the inventory, organizations have three alternate approaches: Economic Order Quantity (EOQ).
Materials Requirements Planning (MRP) and Just-in-Time (JIT).
Discuss those three approaches identify the goal of each one? And how the organization can achieve such a goal?
Part (B)
Some threats could be happened in the production cycle, one of them is over or under production threat.
Discuss two problems and two controls related to this threat.

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?
