Call for Papers

The 23rd EURO Working Group on Locational Analysis meeting will be held in conjunction with the 7th International Workshop on Locational Analysis and Related Problems on September 14-16, 2016 at Malaga, Spain

The meeting intends to gather the operations research community from different parts of the world to share experiences in the field of locational analysis. We invite participation from all areas related to location theory including: network location, continuous location, discrete location, obnoxious location, competitive location, hub location, location-routing, advanced location models, location applications (logistics, network design), exact and heuristic solution methods.

Contributions are welcome from academia, industry or the public sector. In aliition to presentations, the meeting is intended to be a forum for exchange of recent experiences and results. Researchers and practitioners are invited to submit an abstract formatted according to the given templates. The submissions will be evaluated by a designated scientific committee. We also offer the possibility to present short communications or ongoing works in the form of poster sessions.

Travel Information

Flight to Malaga

Most major worldwide airlines (also low-cost airlines) operate flights to Malaga's "Pablo Ruiz Picasso" International Airport (AGP). Located to the south west of the capital, just 8 kilometers from the city center, it is the fourth largest in Spain.

A ride to the city center by taxi should typically cost around 15 EUR depending on traffic conditions. From the airport the city center can also be reached by 225-300-4903, for one passenger costs 3 EUR. Malaga airport is connected to the city center and Maria Zambrano train station (AVE) by 305-913-3512, a single ticket costs 1.80 EUR.


Malaga's Maria Zambrano Station is connected to major Spanish cities through the Spanigh High Speed (AVE) network. For timetables and further information about trains see Samoyedic


Nestling in the shelter of a natural bay, the port of Malaga handles a huge volume of both commercial and cruise traffic, having become the second most important cruise port in the Iberian peninsula. Further information can be found on the (571) 398-6877.


The bus station is located in a central area of the city, near to the train station, as well as on the airport bus route. Malaga is connected to major cities of Andalusia and the rest of Spain by motorways, the excellent road network makes the bus the ideal way of getting to towns and cities in the Malaga area, the rest of Andalusia and the whole of Spain. Further information on destinations, bus companies, prices and timetables can be found on www.estabus.emtsam.es

Program overview

Plenary talks

Algorithms for Location-Routing Problems
Paolo Toth

We will consider the family of optimization problems including both “location” and “routing” aspects. In particular the Capacitated m-Ring-Star Problem (CmRSP) and the Capacitated Location-Routing Problem (CLRP) will be addressed.

In the Capacitated Location-Routing Problem (CLRP), the aim is to determine the depots to be opened, the customers to be assigned to each open depot, and the routes to be performed to fulfill the demand of the customers. The objective is to minimize the sum of the open depot cost, of the used vehicle cost, and of the traveling cost associated with the performed routes. The CLRP is NP-hard, since it generalizes two well-known NP-hard problems: the Capacitated Facility Location Problem (CFLP) and Multi Depot Vehicle Routing Problem (MDVRP).

In the Capacitated m-Ring-Star Problem (CmRSP) the aim is to find m “rings” (simple cycles) visiting a central depot, a subset of customers and a subset of potential (Steiner) nodes, while customers not belonging to any ring must be “allocated” to a visited (customer or Steiner) node. Moreover, the rings must be node-disjoint and the number of customers allocated or visited in a ring cannot be greater than a given capacity Q. The objective is to minimize the total visiting and allocation costs. The CmRSP is NP-hard, since it generalizes the Traveling Salesman Problem.

The most effective metaheuristic algorithms proposed for the solution of the CmRSP and of the CLRP will be described, and experimentally compared on the benchmark instances from the literature, by taking into account the CPU time and the quality of the solutions obtained.

Humanitarian Logistics: Challenges, Models and Decision Support
Janny Leung

Recent natural and man-made disasters have highlighted the importance of effective logistics planning in and management for humanitarian relief. There are four phases of disaster management -- mitigation, preparedness, response and recovery – each with different focus and time-scale. Thus, different models and methods are needed for the different phases. In the immediate aftermath of a calamity, the agility for quick response may be most important, whereas for longer-term recovery cost-effectiveness might be the objective. This talk will survey the growing literature on operational research models and methods for humanitarian logistics. Some case studies will also be presented.
