A manager must decide between two machines. The manager will take into account each machine's operating costs and initial costs, and its breakdown and repair times. Machine A has a projected average operating time of 140 hours and a projected average repair time of 7 hours. Projected times for machine B are an average operating time of 70 hours and a repair time of 6 hours. What are the projected availabilities of each machine? (Round your answer to 3 decimal places). I don't want the answer. I just want to know HOW to do it.
An airline company must plan its fleet capacity and long-term schedule of aircraft usage. For one flight segment, the average number of customers per day is 70, which represents a 65 percent utilization rate of the equipment assigned to the flight segment. If demand is expected to increase to 84 customers for this flight segment in three years, and management requires a capacity cushion of 25 percent, calculate the following:-
the planned capacity requirement.
the maximum number of customers the flight segment can accommodate.
the efficiency rate of the flight segment assuming that the current effective capacity of the
flight segment is 93 customers.
