What is the result of multiplying available time, utilisation, and efficiency?

Multiplying available time, utilization, and efficiency yields rated capacity, which represents the maximum output that can theoretically be produced under ideal conditions. Rated capacity takes these factors into account: available time is the total time an operation is open for production, utilization measures how effectively that available time is being used (expressed as a percentage of the time available), and efficiency assesses how well the actual work being produced aligns with the expected output during that time, factoring in any potential delays or inefficiencies.

While effectiveness, useful capacity, and demonstrated capacity are relevant concepts, they do not accurately represent the formula in question. Effectiveness is more about how well outputs meet desired outcomes. Useful capacity can refer to the capacity that can actually be used for production after considering constraints, whereas demonstrated capacity reflects the output actually achieved in practice but does not combine the elements of time, utilization, and efficiency in the manner outlined in the question. Therefore, rated capacity is the correct outcome of the multiplication of these specific variables.
