Ohio University's College of Business uses integer programming to schedule classes

Ohio University's College of Business uses an integer-programming model to assign instructors to courses, classrooms, and time slots. The model deals with a variety of issues, such as back-to-back classes, maximum number of teaching days, time slots of any configuration, multiple instructors for courses, department balance, and preassignments. CPLEX solves the problem for the College of Business quite easily. The college has used the model for about six years, and the administration and faculty view it very favorably.
