We conduct a comprehensive review on multi-level facility location problems which extend
several classical facility location problems and can be regarded as a subclass within the …

The Steiner tree problem (STP) in graphs is one of the most studied problems in
combinatorial optimization. Since its inception in 1970, numerous articles published in the …

In this paper we study the cost-optimal deployment of optical access networks considering
variants of the problem such as fiber to the home (FTTH), fiber to the building (FTTB), fiber to …

Abstract The Workforce Problem (WP) can be classified in three categories: strategic
planning, tactical planning and operational planning. The WP can be applied to any type of …

An influential factor affecting the efficiency of a manufacturing facility is its layout. In a
production facility, measure for efficiency can be based on the total cost of transporting the …

We introduce a two-level distribution network design problem to serve a set of demand
points. At the higher level, primary facilities with source capabilities feed secondary facilities …

Telecommunications is an important area of application in combinatorial optimization. A
large class of problems encountered by telecommunications operators are related to …

We consider the incremental connected facility location problem (incremental ConFL), in
which we are given a set of potential facilities, a set of interconnection nodes, a set of …

We introduce the bi-objective prize-collecting Steiner tree problem, whose goal is to find a
subtree considering the conflicting objectives of minimizing the edge costs for building that …

In this paper, we deal with two routing problems that integrate coverage and cardinality
constraints to optimize the wireless sensor networks lifetime. Problems based on …
