The Variance Location Problem on a Network with Continuously distributed demand

Ma Cruz López de los Mozos, Juan A. Mesa (2010)

RAIRO - Operations Research

Similarity:

Most location problems on networks consider discrete nodal demand. However, for many problems, demands are better represented by continuous functions along the edges, in addition to nodal demands. Several papers consider the optimal location problem of one or more facilities when demands are continuously distributed along the network, and the objective function dealt with is the median one. Nevertheless, in location of public services it is desirable to use an equity criterion. One...

The Capacitated Arc Routing Problem. A heuristic algorithm.

Enrique. Benavent, V. Campos, Angel Corberán, Enrique Mota (1990)

Qüestiió

Similarity:

In this paper we consider the Capacitated Arc Routing Problem, in which a fleet of K vehicles, all of them based on a specific vertex (the depot) and with a known capacity Q, must service a subset of the edges of the graph, with minimum total cost and such that the load assigned to each vehicle does not exceed its capacity. A heuristic algorithm for this problem is proposed consisting of: the selection of K centers, the construction of K connected graphs with associated loads...

Lexicographic -robustness: an application to the 1-median problem

R. Kalaï, M. A. Aloulou, Ph. Vallin, D. Vanderpooten (2010)

RAIRO - Operations Research

Similarity:

In the last decade, several robustness approaches have been developed to deal with uncertainty. In decision problems, and particularly in location problems, the most used robustness approach rely either on maximal cost or on maximal regret criteria. However, it is well known that these criteria are too conservative. In this paper, we present a new robustness approach, called , which compensates for the drawbacks of criteria based on the worst case. We apply this approach to the 1-median...
