| 2010 | 172,177 | $63,123,887,517,709.30 |
Based on the information provided in the above table, answer the following two questions.
(1) Develop one graph to display the historical annual world air freight traffic and world GDP from 2001 to 2010, using 2001 as the baseline year.
(2) Based on the historical world air freight traffic and world GDP data during 2001 and 2010, do you find the support for the argument that the world air freight grows about twice as fast as world GDP in the time period concerned? Explain how you prove whether this argument holds true
Question 3 (10 points):
Using the same information provided in the class simulation exercise “DHL Supply Chain (02/27/14)” and the corresponding SOLVER template available on Blackboard, calculate the minimum carbon emission associated with having a budget of CNY 3.63 billion for the total production and shipping costs.
Based on the optimization solutions derived from SOLVER, put the results into the corresponding blanks to complete the following supply chain matrix.
