Professor Bodin's major research activities in in developing models and algorithms to solve like optimization models - primarily combinatorial optimization and vehicle routing problems. Most of Professor Bodin's activities have been concerned with the solution of these routing problems over geographic data bases and the problems that are encountered when the solution has to be imbedded on top of a street network. The systems that Professor Bodin has helped develop are being used by some of the major delivery companies, newspaper delivery companies, public utilities and sanitation companies. Professor Bodin spent a year on sabbatical at the University of Bologna in Italy. There, he worked with Professor Aristede Mingozzi and his colleagues on the analysis of the Rollon-Rolloff problem, a problem encountered by most major sanitation companies. Additionally Professor Bodin gave a series of lectures at the University of Bologna on mathematical modeling and vehicle routing over street networks.
