Value Gadgets Corp. produces J-Pods, music players that can download thousands of songs. Value Gadgets forecasts that demand in 2017 will be 19,500 J-Pods. The variable production cost of each J-Pod is $50. In its MRP system, due to the large $22,750 cost per setup, Value Gadgets plans to produce J-Pods once a month in batches of 1,625 each. The carrying cost of a unit in inventory is $21 per year.

Question:

1.	Using the MRP system, what is the annual cost of producing and carrying J-Pods in inventory? (Assume that, on average, half of the units produced in a month are in inventory.)
2.	A new manager at Value Gadgets has suggested that the company use the EOQ model to determine the optimal batch size to produce. (To use the EOQ model, Value Gadgets needs to treat the setup cost in the same way it would treat ordering cost in a traditional EOQ model.) Determine the optimal batch size and number of batches. Round up the number of batches to the nearest whole number. What would be the annual cost of producing and carrying J-Pods in inventory if it uses the optimal batch size? Compare this cost to the cost calculated in requirement 1. Comment briefly.
3.	Value Gadgets is also considering switching from an MRP system to a JIT system. This will result in producing J-Pods in batch sizes of 500 J-Pods and will reduce obsolescence, improvequality, and result in a higher selling price. Value Gadgets will reduce setup time and setup cost. The new setup cost will be $400 per setup. What is the annual cost of producing and carryingJ-Pods in inventory under the JIT system?
4.	Compare the models analyzed in the previous parts of the problem. What are the advantages and disadvantages of each?
