3. Four workers of different experience levels are used to pick orders in a warehouse aisle. The
pickers work like a bucket brigade and the demand for items in each order is evenly distributed
across the aisle. Alice can pick four items per minute, Bruce can pick athree items per minute,
Carol can pick five items per minute and Dennis can pick six items per minute. Arrange the
workers to maximize the throughput rate for picking orders and determine the portion of the line
each will occupy in steady state. If the typical order has twenty line items to be picked, how
many orders will this team pick per hour?
