There are 20 automatic turning machines in the lathe department. batches of parts are machined in the department. each batch consists of setup and run times. batch size = 100 parts. the standard time to set up a machine for each batch is 5.0 hours. four setup workers perform the setups. they each work 40 hours per week. once a machine is set up, it runs automatically, with no worker attention until the batch is completed. cycle time to machine each part = 9.0 min; thus, it takes 15 hours of run time to produce a batch. assume all machines are perfectly reliable. what is the production output of the lathe department in 40 hours of operation per week?
