Jackie Chen, vice president of China Imports, was look$-$ ing to design a framework to select transportation modes for various products imported from China to the United States. His basic options were to either use air freight or ocean shipping in $20-$foot containers. Air freight was faster and more reliable, but ocean shipping was much cheaper. He decided to evaluate the shipping decision for two very different product categories$$consumer electronics, such as smartphones, and decorative hard$-$ ware, such as door handles and hinges.
