“…The UA-FLP has been tackled before in a large number of research works. Among them, we can highlight some Deterministic Methods (Montreuil, 1991;Meller et al, 1998;Sherali et al, 2003;Castillo et al, 2005;Norman and Smith, 2006;Saraswat et al, 2015;Purnomo and Wiwoho, 2016) that have optimally solved the problem with up to 12 facilities (Chae and Regan, 2016). However, meta-heuristic proposals (Ramadas and Abraham, 2019) have been much more used to solve the UA-FLP, especially in problems with a large number of facilities, where deterministic approaches cannot be applied due to their excessive computational complexity.…”
