Answer to Question #279427 in Mechanical Engineering for aaron

Question

a) Define Maintainability and availability and compare it with reliability.

b) What is inspection and repair availability model? Explain a case for it.  

Answer 1

• Maintainability refers to how much time or resources are required to fix failures. It’s also known as serviceability and essentially measures how easily something can be repaired.

• Availability refers to the probability that the hardware or software in question is operational and ready to use. It’s also often known as the time it’s expected to function.

• reliability is the probability of a piece of hardware or software performing its intended purpose well and for a certain amount of time. Of course, different systems will have their own criteria for what counts as ‘working well’ and different amounts of time expected.
