Introduction Mortality calculations are an important part of a product's life cycle. Ideally, an engineer should know how long a system will last for, and a company can then know how long they will have to provide maintenance services for that system.
From the customer perspective, the lifespan calculation serves as a useful life estimate: However, there are mitigating circumstances which may keep a system operating after its estimated lifespan. These circumstances can range from customer loyalty to a product line to spectacularly botched system upgrades; and despite the best intentions and loudest warnings of system designers, systems will be used past the end of their lifespan.
It is consequently important not only to understand that this does happen, but why. The bathtub curve illustrates the expected failure rates for systems.
As can be seen, systems start out with a high failure rate the infant mortality periodthen settle down to a life of fairly stable operation.
However, as the system reaches the end of its lifespan, its failure rate increases once again as various physical failures accumulate: End of lifespan wearout is concerned with how systems behave once they reach this far end of the curve.
End of lifespan behavior is a somewhat thorny issue when dealing with safety critical systems. Systems should fail in a safe fashion, but the unpredictable nature of failure modes means that the safest option is to completely shut off and remove the system.
Unfortunately, there are a variety of systems, such as Air Traffic Control systems, which require continuous operation. Frustratingly, these systems are also inordinately difficult to replace.
In other cases, shutting off a segment of a system may have political implications. Cars tend to be sold and resold, going through one or more income brackets with each sale.
As cars become more sophisticated, certain expensive and sophisticated systems are becoming commonplace. Cruise control is a good example. A car without cruise control can still operate, but a faulty cruise control system can easily cost lives. While the obvious solution is to completely eliminate the cruise control system once it reaches the end of its safe lifespan, this raises unpleasant legal issues.
As noted below, systems tend to be passed down in hierarchies - in the case of cars, the hierarchy is economic. Shutting down cruise control could be considered the equivalent of limiting safety to those who can afford it.Suggested Essay Topics.
