A component must have reliability of .9925. Two technologies are available for this component: one produces a component with .999 reliability at a cost of $2000. Another produces a component with .73 reliability at a cost of $450. Which is cheaper: one high quality component or a parallel set of inferior components?
Component Reliability
The likelihood of a component to perform its required function under stated conditions for a specific period.
Parallel Set
A visualization technique used to display the relationships across multiple categorical variables.
- Recognize the importance of redundancy along with component quality in maintaining superior system reliability.
- Evaluate the cost-effectiveness of preventive maintenance versus breakdown repair.

Final Answer :
First determine how many of the 0.73 reliable components are needed: 2: 0.9271 3: 0.980317 4: 0.994686 Four are needed, which will cost $1800. This is cheaper than the $2000 single high-quality component.
