The repetitive work cycle in a worker-machine system consists of the work elements and
associated times given in the table below. As the table shows, all of the operator’s elements
are external to the machine time. (a) Construct a worker-machine activity chart for this work cycle. (b) Can some of the worker’s elements be made internal to the machine cycle? If so, construct a worker-machine activity chart for the revised work cycle. What is the approximate cycle time for the revised cycle?
