A machine needs to be immediately replaced in a certain manufacturing facility, as the machine downtime costs are $2,000 per hour. The supply manager looking to purchase a machine was evaluating two alternatives.
Machine A |
Machine B |
|
Cost |
$100,000 |
$125,000 |
Delivery time |
50 days |
45 days |
Downtime costs |
$2,000 / hour |
$ 2,000 / hour |
- Calculate the lost revenue based on delivery time difference and downtime costs, considering the machines will run 8 hours a day / 7 days a week.
- Based on your results, what is the best alternative and why? Explain quantitively.
- Consider now a different scenario. You have acquired Machine B, but just realized the production capacity of machine A is 10% higher. Your demand forecast has been stable, until your part sales have suddenly increased from $10,000 to $11,000 per day.
- Considering you have acquired machine B, what would be the daily lost revenue in sales during a 15 days period?
- Considering lost sales in a 15-day period against lost revenues based on delivery time (question a), would you still have acquired machine B? Why?
