Areas of Focus
Scheduling is big business. In fact, producing a balanced schedule is more than a matter of simply running the numbers. Whether you are scheduling personnel, aircraft fleets, ocean containers, or even Major League Baseball games, creating a balanced schedule is extremely complex because of the vast number of factors that must be taken into account. As financial and competitive stakes in industry continue to rise, so does the complexity of scheduling.
In response to industry challenges, the Stewart School of ISyE established a Center of Focused Research in Resource Scheduling. Housed in the Supply Chain and Logistics Institute (SCL), the Resource Scheduling Center is directed by Dr. George Nemhauser, the A. Russell Chandler III Chaired Professor. Along with Dr. Nemhauser, Professors Shabbir Ahmed, Martin Savelsbergh, and Joel Sokol also work in resource scheduling for a wide variety of industries. Their work involves developing models and algorithms that provide practical solutions for large-scale scheduling problems, scheduling scarce resources under complex constraints, scheduling issues including variability and uncertainty, and integrating-collaboration and optimization in the development of schedules.
Applications range from scheduling machines in a factory to an airline assigning thousands of pilots to flights to major league baseball creating schedules of 162 games for each of 30 teams. All of these problems have complex constraints and many variables. The resource scheduling center employs faculty and PhD student expertise to develop models and algorithms to solve such problems.
