problem 1: The steady state operational availability of a complex system is associated to the system MTBF, MTTR, MLDT and MADT as shown below:
Ao = MTBF/(MTBF + MTTR + MLDT + MADT)
The contractual needs are as shown below:
MTBF = 6 hrs,
MTTR = 1.5 hour,
Ao = 0.95.
describe the process and establish contractual needs for MLDT and MADT. Use sketches and computations to justify your required values.
