You have just been promoted as the head of the shipping department for your office supply company, and it is now your responsibility to determine routing. The company is located on the eastern seaboard near major highways as well as the ocean. In the past, trucking has been the preferred method of shipping, as it was deemed the most cost effective. Shipping by boat, however, would greatly reduce the negative effects on the environment caused by truck emissions. After calculating the cost on paper, you realize that shipping by sea would have a negative effect on the overall profit margin, but the company would still generate solid profits.
