A manufacturer produces shirts in two steps. The first step, cutting fabric, is an automated batch process (which requires no labor) that takes 1 hr per batch, regardless of the size of the batch. The second step is sewing, with a capacity of 50 shirts/hr (10 workers, each taking 12 mins per shirt). The manufacturer is currently using a batch size of 30. Suppose the batch size is increased to 60 shirts. Choose the only correct alternative.
a) The capacity of the overall process is doubled.
b) The capacity of the overall process is 50 shirts/hr.
c) The capacity of the overall process does not change.
d) None of the above.
