Modelling a timetabling problem related to academic conferences and solutions throught exact method

This study has approched timetabling problems and use them in academic conferences in order to arrange the submitted papers to scheduled presentations, those have assigned one theme among several, to be presented in a given room and timeslot provided by the conference. Futhermore, applied timetabling problems were reviewd to gather knowledge in how those were mathematically modelled and which solution methods were used to solve them. In the case study conducted in a large scientific conference in Brazil, an optimization model was built and an exact method (Simplex by Gurobi solver) was employed to solve the problem. The outcomes are promissing and this study remains in the authors agenda.
