Maintenance $121201690865$ What is the design capacity of the machines? Specifically, what are the available hours of operation when only considering days of closure? To find the design capacity of the machines, we need to calculate the total time available for production each year. We can do this by finding the number of minutes in a year and subtracting the time required for maintenance and closure.
