One million units of a certain product are to be manufactured annually on dedicated production machines that run 24 hours per day, five days per week, and 50 weeks per year.
(a) If the cycle time of a machine to produce one part is 1.0 minute, how many of the dedicated machines will be required to keep up with demand? Assume that availability, utilization, worker efficiency = 100%, and that no setup time will be lost.
(b) Solve part (a) except that availability = 0.90.
