Background Health Logistics Association (HLA) is an association of logistics professionals committed to humanitarian logistics effectiveness by creating opportunities for dialogue and cooperative relationships with its members and partners to build a community of practice for advancing the humanitarian logistics profession through the promotion of cross organisational learning and collaboration...

The goals of hub location problems are finding the location of hub facilities and determining the allocation of non-hub nodes to these located hubs. In this work, we discuss the multi-modal single allocation capacitated p-hub covering problem over fully interconnected hub networks. Therefore, we provide a formulation to this end. The purpose of our model is to find the location of hubs and the ...

Disasters trigger the need for relief items. The flows of relief items to the beneficiaries in the disaster area are determined by humanitarian logistics networks. The setup and operations of such networks can be supported by employing Operations Research models. Several models, based on different methodologies are available to support decision-making in the field of humanitarian logistics. Thi...

We consider the class of integrated network design and scheduling (INDS) problems that focus on selecting and scheduling operations that will change the characteristics of a network, while being specifically concerned with the performance of the network over time. Motivating applications of INDS problems include infrastructure restoration after an extreme event and building humanitarian logisti...

We introduce a new class of distributionally robust optimization problems under decision-dependent ambiguity sets. In particular, as our sets, we consider balls centered on probability distribution. The are based earth mover’s distances that includes both the total variation distance and Wasserstein metrics. discuss main computational challenges in solving interest provide an overview various s...

Hubs are critical elements of transportation networks. Location of hubs and allocation of demands to them are of high importance in the network design. The most important purpose of these models is to minimize the cost, but path reliability is also another important factor which can influence the location of hubs. In this paper, we propose a P-center hub location model with full interconnection...

restructuring the recent developments in the power system and problems arising from construction as well as the maintenance of large power plants lead to increase in using the distributed generation (dg) resources. dg units due to its specifications, technology and location network connectivity can improve system and load point reliability indices. in this paper, the allocation and sizing of di...

The general facility location problem and its variants, including most location-allocation and P-median problems, are known to be NP-hard combinatorial optimization problems. Consequently , there is now a substantial body of literature on heuristic algorithms for a variety of location problems, among which can be found several versions of the well-known simulated annealing algorithm. This paper...

This chapter focuses on an auction-based procurement framework for single coordinating platforms in humanitarian logistics. It first covers disaster relief operations, humanitarian logistics, and procurement in this context and illustrate many of the issues that make the management and coordination of procurement functions complex and challenging. Then the proposed framework along with the auct...
