To calculate the availability of Port 7, we need to determine the total downtime during the specified operational hours and the total operational hours for the week.

Total operational hours:

Monday to Friday: 12 hours/day * 5 days = 60 hours

Total downtime during operational hours:

Monday: 1 hour (11 AM to 12 PM)

Wednesday: 5 hours (4 PM to 9 PM)

Thursday: 0 hours (4 AM to 9 AM is outside operational hours)

Friday: 4 hours (2 PM to 6 PM)

Saturday: 0 hours (Saturday is outside operational hours)

Total downtime = 1 + 5 + 4 = 10 hours

Total available hours= 60 hours - 10 hours = 50 hours

Availability= (Total available hours / Total operational hours) * 100Availability=(5060)×100=83.3%Availability=(6050​)×100=83.3%
