A plant operates three continuous daily shifts of eight hours each for five days in a week. One unit of the
resource R1 within the plant is assigned for two shifts to work area W1. On a particular day in a given week,
due to unscheduled maintenance that needed to be performed on the resource R1, it was not available for two
hours during each of the assigned shifts.
Determine the available capacity of the resource R1 for that week.
