Find the decrement of failure intensity per failure, Software Engineering

Assignment Help:

Q. Assume that a program will experience 200 failures in infinite time. It has now experienced 100. The initial failure intensity was 20 failures/CPU hr.

(i) Determine the current failure intensity

(ii) Find the decrement of failure intensity per failure.

Ans: Here

Vo=200failure

μ=200failure

l o=200failure/ CPUhr

 (i) Current failure intensity:
