Antonio Sassano is currently Full Professor of Operations Research at the Faculty of Engineering of the University of Rome “La Sapienza”. His scientific and professional activity has been focused in two complementary areas: the study of the Mathematical Structure of Hard Optimisation Problems and the Use of this Knowledge to Model and Solve Challenging “real life instances”. His research activity has been mainly devoted to the study of the polyhedral structure of combinatorial problems and to the design and testing of optimisation algorithms. His consulting experience includes the design of the Italian Frequency Plan for Terrestrial Analog Television in 1998, the study of the Frequency Plan for FM-Radio and, more recently, the design of the DAB Frequency Plan, of the 3-SFN DVB-T Frequency Plan, and the SFN DVB_T Frequency Plan. Has been one of the advisors of the Italian Government (as a consultant of Crediop-Nera) in the auction procedures for the UMTS licenses (2001) and the WLL licenses (2002).
