We are pleased to welcome you to the XVth Conference of the International Association for Fuzzy-Set Management and Economy (SIGEF). The meeting will be held October 29-30 at the School of Business Administration of the University of Santiago de Compostela in Lugo, Spain.

Lugo is the name of a city and a province in the north west region of Spain called Galicia. The city of Lugo was "formally" founded by the romans sometime around 70 B.C. Among its various important monuments it has the only complete round roman wall in Spain. The wall was built by the romans as a way to keep the city safe from enemy attacks. Lugo is located in a hill and the wall surrounds its top. During the following centuries, numerous modifications and repairs were needed to preserve it, but it still stands today as the most prominent symbol of the city. It has a perimeter of around 2.200 meters (1.375 miles). It surrounds the "downtown" part of the city and it has several entrances. Inside this roman wall, we find its beautiful Romanesque cathedral. Currently, the walls are protected by UNESCO as a World Heritage .
