Abstract: Corrective Maintenance Cost is the percentage of total maintenance cost that is used to restore equipment to a functional state after a failure or when failure is imminent. This metric quantifies the financial impact of work done on corrective maintenance tasks.
The Middle Way provides a way forward in all kinds of judgements, whether scientific, moral or aesthetic. 1  Its key insight is one that joins psychology to philosophy: that there are certain types of views that can only be held in a state that involves psychological rigidity, and thus are not well justified in a wider philosophical perspective.
I take middle class to mean: - You own a home, can afford mortgage, insurance, taxes and upkeep - You can afford to raise a family (a middle class that does not reproduce it self is not sustainable. We should not have to live like monks.) - You can afford to send your kids to college (ok, maybe a state school, but still send to college)
