Question:
1.Global Airspan Freightways must determine the best location for a new aircraft maintenance center to support its fleet of 56 airplanes. The company has identified five airports as candidate locations for the new maintenance center: Narita Airport in Tokyo (NRT), Changi Airport in Singapore (SIN), Los Angeles Airport in California (LAX), Guarulhos International Airport in Sao Paulo (GRU) or the Buffalo/Niagara Falls Airport (BUF). Global Airspan Freightways only considers two issues as important when choosing one of these locations for its new maintenance center. The first issue is the airports’ ‘Centrality within Global Airspan Freightways’ Network’, which refers to how far, on average, any one of its airplanes would need to fly to and from its assigned freight route to receive maintenance at the new maintenance center. The second issue is ‘Local Operating Costs’, in that the cost of operating the center at each of the five airports varies. Global Airspan Freightways has created a ten-point scale, in which higher scores always indicate more favorable conditions, and has rated each of the five airports according to this scale:
NRT | SIN | LAX | GRU | BUF | |
Centrality within Global Airspan Freightways’ Network | 4 | 7.5 | 5 | 5.5 | 4 |
Local Operating Costs | 2.5 | 6 | 3 | 7.5 | 8 |
Please answer the following two questions, based on this information.
Which of the following statements is (are) true?
I. SIN has lower local operating costs than GRU.
II. SIN is the least convenient in terms of ‘Centrality within Global Airspan Freightways’ Network’.
III. NRT has the highest local operating costs of all five airports.
Select one or more:
a. I and II
b. I, II, and III
c. I
d. II and III
e. III only
