for

OM Explorer

A community hospital in Southeast Ohio consumes 1,000 boxes of bandages per week. The price of bandages is $35 per box, and the hospital operates 52 weeks per year. The ordering cost is $15, and the cost of holding one box is 15% of the price of the material. The lead time to receive materials is 2 weeks.

Problem a) Currently, the hospital orders bandages in lot sizes of 900 boxes for total costs of $3,229.16.

Problem i. Calculate the EOQ quantity using OM explorer. Enter 50% for cycle-service level on Inputs tab. What is the EOQ quantity? (see Inputs tab)

Problem ii. What are the costs for this EOQ quantity? (see Results tab)

Problem iii. How much money could the hospital save by using the EOQ quantity instead of the lot size of 900?

Problem b) What happens to the EOQ quantity when the unit price doubles? How does that change the ordering behavior of the manager? Why does that make economic sense?

Problem c) What happens to the EOQ quantity if the ordering costs go down by 20% - to $12 per order (use original unit price, $35/box)?

Problem d) The EOQ is the optimal lot size that minimizes the sum of holding & ordering costs. Is there any reason a company wouldn't want to use the EOQ?

UNCERTAIN DEMAND (STANDARD DEVIATION ≠ 0)

Problem e) Demand is still 1000 boxes per week and is normally distributed, with a standard deviation of weekly demand of 100 boxes. Use cost information from original problem statement.

Problem i. What safety stock is necessary if the hospital uses a continuous review system and a 97% cycle-service level is desired?

Problem ii. What is the reorder point? (HINT: Use weekly demand numbers for this calculation)

Problem iii. What is the cost of using the continuous review system?

Problem iv. How does the safety stock change if lead time is reduced from 2 weeks to 1 week?

Problem v. What happens to overall costs if cycle-service level is reduced to 80% (use original lead time = 2 weeks)? Which industries/business might use a lower cycle-service level?

Problem f) If the hospital uses a periodic review system, with the review period (P) equal to 2 weeks and cycle-service level of 97%:

Problem i. What would be the target inventory level, T? (Use the original information from part e)

Problem ii. What is the cost of using the periodic review system?

Problem iii. Compare/Contrast the continuous review system and periodic review system in terms of safety stock and costs. What are the managerial implications of each?
