The International Federation of the Red Cross and Red Crescent (IFRC), is one of the many humanitarian organizations that are further developing their logistics network more decentralized structures with sub-regional networks. One of the main challenges identified is the need of monitoring tools to have a real-time overview of the whole logistics network state, and optimization of the associate...

A filtering power divider/power combiner based on half mode substrate integrated waveguide technology for high power applications is proposed. This design includes one half mode substrate integrated waveguide cavity, one matched load, and four sections of quarter-wavelength transmission lines. The high isolation between output ports is obtained by combining the half mode substrate integrated wa...

The present study implements a generic methodology for describing and analyzing demand supply networks, that is, networks from a company’s suppliers to its customers. There can be many possible demand supply networks with different logistics costs for a product. Therefore, we introduce a Petri Net-based formalism, and a reachability analysis based algorithm that finds the optimum demand supply ...

This paper presents a study that characterizes, formulates, and solves the reverse logistic network design. A Mixed Linear Program model is formulated that systematically minimizes reverse logistics operating costs for the strategic problem facility location of collection sites, cannibalization and recycling. The facility location is a central issue of the logistics networks. In this paper we a...

During the last decade, the stringent pressures from environmental and social requirements have spurred an interest in designing a reverse logistics (RL) network. The success of a logistics system may depend on the decisions of the facilities locations and vehicle routings. The location-routing problem (LRP) simultaneously locates the facilities and designs the travel routes for vehicles among ...

Traditionally, the design of a transportation system has focused on one of the two systems that comprise the transportation architecture, the vehicle or the network design. However, to define a systems level architecture for a transportation system, it is necessary to expand the system definition during the design process to include the network definition, the vehicle architecture, and the oper...

Hitherto, instrumentation network design methodologies have been based solely upon sensor capital costs. Within this framework the cost of new instrumentation is minimized subject to constraints indicating the desired level of performance. While, these formulations account for the cost of a network, they do not reflect the potential benefit of adding sensors. To capture this potential profit, w...

An important service provided by third-party logistics (3PL) firms is to manage the inbound logistics of raw materials and components from multiple suppliers to several manufacturing plants. A key challenge for these 3PL firms is to determine how to coordinate and consolidate the transportation flow, so as to get the best overall logistics performance. One tactic is to establish consolidation h...
