As diferentes relaxações de um problema de programação inteira permitem que se obtenham limites da solução ótima do mesmo. Entre as relaxações mais usadas destacam-se as de programação linear, Lagrangeana, surrogate e combinada Lagrangeana

We present a 3-level hierarchical model for the location of maternal and perinatal health care facilities in Rio de Janeiro. Relaxations and heuristics are developed for this model and computational results are given for problems available in the lit

Variations of the classical Vehicle Routing Problem (VRP) consider clients that require pick-up and delivery service, simultaneously or not. Each variation corresponds to a specific routing policy, applicable to a given context. Although several rout

The objective of the present paper is to analyze the use and solution of the hypercube model for the case of non-homogeneous servers (servers with different mean service times). Systems with non-homogeneous servers can be found in several real world

We compare heuristics based on Lagrangean and surrogate relaxations of the Maximal Covering Location Problem (MCLP). The Lagrangean relaxation of MCLP used in this paper has the integrality property and the surrogate relaxed problem we solve is the L

We present a statistical analysis of simulated annealing applied to the p-median problem. The algorithm we use combines elements of the vertex substitution method of Teitz and Bart with the general methodology of simulated annealing. The cooling sche

Modelos matemáticos de localização têm tido aplicação crescente na área de saúde em nível internacional. No Brasil, embora de uso incipiente, existe enorme potencial para a utilização desses modelos na área de saúde pública. Nesse senti
