Abstract:

NORC has integrated GIS and linear programming to automatically assign cases with the goal of minimizing distance between interviewers and cases in recent years. Traditionally, this assignment process had been performed manually by field managers using their local knowledge. While our new automatic assignment method took advantage of distances calculated in GIS to considerably improve efficiency, there remained room for improvement as factors other than distance to case were often salient in assigning cases to interviewers. In 2009, NORC enhanced its assignment making software to incorporate additional factors such as language of cases and interviewers, experience of interviewers and case history. This paper summarizes these improvements and introduces an off-shoot of the assignment making program which assigns entire target segments based on distance and number of cases in each segment.
