This case is based on a project conducted for a pharmaceutical company, Pfizer. Sales representatives of pharmaceutical companies typically visit medical doctors regularly to promote their products. There are a number of criteria that may be of interest in assigning representatives to a group of doctors: minimizing total distance traveled by representatives, balancing the workload of representatives, and minimizing the disruption in the assignments of each representative are three main concerns. In this case study, a realistic scenario is created for students to attempt to find meaningful solutions to this multiple criteria problem from practice.
