A company has three (3) components in a system and requires all three to be operational for 24 hours, Monday to Friday. Failure of component 1 occurs as follows: Monday = No failure. Tuesday = 5 a.m. to 7 a.m. Wednesday = No failure. Thursday = 4 p.m. to 8 p.m. Friday = 8 a.m. to 11 a.m. Directions: Using the scenario above, respond to the items below. Calculate the MTBF (Mean Time Between Failures) and MTTR of component 1. Show your steps of how you calculated the MTBF. Steps: MTBF = Total Uptime / Number Failures Total Uptime = (Number of Days Required Operational x Hours per Day Available) - Number of Hours Not Available MTTR = Total Downtime / Number of Failures What does the MTBF measurement tell you about the goal of having 99.999% uptime or Information Availability on system components?

Solution

#include<iostream>
using namespace std;
int main()
{
float MTBF, MTTR, Tup;
// Calculates Total Uptime
//Total Uptime = (Number of Days Required Operational x Hours per Day Available) - Number of Hours Not Available
Tup = (4 * 24) - 9;
//Calculates Mean Time Between Failures
//MTBF = Total Uptime / Number Failures
MTBF = Tup / 3.0;
//MTTR = Total Downtime / Number of Failures
MTTR = 9 / 3;
cout<<\"\ MTBF = \"<<MTBF;
cout<<\"\ MTTR = \"<<MTTR;
}

Output:

MTBF = 29
MTTR = 3
