Part II: Problem-Solving Questions (25 points)
Question 1 (5 points):
Hindustan Aeronautics Ltd. supplied aircraft doors to a
leading aircraft manufacturer. In 2013, it made a total of 120 deliveries. The
following table presents a summary of lead time performance for all the 120
delivery cycles. Based on the information provided in the table, calculate the
mean lead time and its coefficient of variation.

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.
