The Port of Endover operates six berths and 12 cranes for loading and unloading freight containers from ships, organized into two areas known as the north terminal and the south terminal. The Port of Endover's north ter- minal contains two of the ship berths and four of the cranes, which worked together almost continuously last week, handling (loading or unloading) a total of 14,599 freight containers during 151 hours of operation. Similarly, the eight cranes of the larger south terminal operated together over 160 hours last week, collectively handling 29,753 containers.

Questions 

1. Consider the simple partial productivity measure "per crane." What was the overall per crane productivity of the Port of Endover last week?

2. What was the "per hour of operation" productivity of the north terminal last week? What was the "per hour of operation" productivity of the south terminal last week?

3. The four cranes of the north terminal require one crane operator each, plus two additional employees on the ground as "spotters." The south terminal also requires one crane operator for each of the cranes, plus three spotters on the ground as this group of cranes operates. Taking the crew sizes and their operating times into con- sideration, what is the labor productivity of the north terminal? What is the labor productivity of the south terminal?
