(Production constraints) Office Provisions produces commercial calendars in a two-department operation: Department 1 is labor intensive and Depart¬ ment 2 is automated. The average output of Department 1 is 45 units per hour. Units from Department 1 are transferred to Department 2 to be com¬ pleted by a robot. The robot can finish a maximum of 45 units per hour. Office Provisions needs to complete 180 units this afternoon for an order that has been backlogged for four months. The production manager has in¬ formed the people in Department 1 that they are to work on nothing else except this order from 1 p.m. until 5 p.m. The supervisor in Department 2 has scheduled the same times for the robot to work on the order. Depart¬ ment l’s activity for each hour of the afternoon follows:

Each unit moves directly from Department 1 to Department 2 with no lag time. Did Office Provisions complete the 180 units by 5 p.m.? If not, explain and provide detailed computations.
