  The International Workshop on Locational Analysis and Related Problems will
take place during January 23-24, 2020 in Seville (Spain). It is organized by
the Spanish Location Network and the Location Group GELOCA from the Spanish
Society of Statistics and Operations Research(SEIO). The Spanish Location
Network is a group of more than 140 researchers from several Spanish
universities organized into 7 thematic groups. The Network has been funded by
the Spanish Government since 2003.
  One of the main activities of the Network is a yearly meeting aimed at
promoting the communication among its members and between them and other
researchers, and to contribute to the development of the location field and
related problems. The last meetings have taken place in C\'adiz (January
20-February 1, 2019), Segovia (September 27-29, 2017), M\'alaga (September
