Efficient implementation of closed‐loop supply chains requires setting up appropriate logistics
structures for the arising flows of used and recovered products. In this paper we consider …

In this paper, a multi-objective decision aiding model is introduced for allocation of beds in a
hospital. The model is based on queuing theory and goal programming (GP). Queuing …

In this article, we examine how an Operational Research (OR) modeling approach can help
in identifying how structural components in the supply process of a food product subject to a …

This paper presents a new local search algorithm for the capacitated arc routing problem (CARP).
The procedure uses single vehicle moves and moves that operate on two routes, both …

This paper expands previous work dealing with oligopolistic supply chains to the field of
closed-loop supply chains. The model presented has been formulated with the intent of …

The different chapters of this book highlight manifold examples of reverse logistics programs.
While these cases vary substantially with respect to products, actors, and underlying …

In this paper, we propose a general agent-based distributed framework where each agent is
implementing a different metaheuristic/local search combination. Moreover, an agent …

Transport companies may cooperate to increase their efficiency levels by, for example, the
exchange of orders or vehicle capacity. In this paper a new approach to horizontal carrier …

Many organisations are composed of multiple departments connected either in series or in
parallel, which may be further decomposed into a number of functions arranged in a …

It is not yet known to what extent reverse logistics might increase the total amount of transportation
in supply chains-partially since it will also reduce activities related to the use of new, …
