Exercise 1: MTBF and MTT
- A system has three components and requires all three to be operational for 24 hours from Monday to Friday. Failure of component 1 occurs as follows:
- Monday = No failure
- Tuesday = 5 am to 7 am
- Wednesday = No failure
- Thursday = 4 pm to 8 pm
- Friday = 8 am to 11 am
Calculate the MTBF and MTTR of component 1.
Exercise 2: Information Availability
- A system has three components and requires all three to be operational from 8 am to 5 pm business hours, Monday to Friday. Failure of component 2 occurs as follows:
- Monday = 8 am to 11 am
- Tuesday = No failure
- Wednesday = 4 pm to 7 pm
- Thursday = 5 pm to 8 pm
- Friday = 1 pm to 2 pm
Calculate the availability of component 2.
