Assessing the carbon emission effects of consolidating shipments

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1493692

This paper studies the effect on carbon emissions of consolidation of shipments on trucks. By utilizing existing vehicle capacity better, one can reduce distance and thereby carbon emission reductions. Our analysis determines the emission savings obtained by a transport provider that receives custom...

Combining pickups and deliveries in vehicle routing - An assessment of carbon emission effects

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1485149

This paper studies the effect on carbon emissions of consolidation of shipments on trucks. By utilizing existing vehicle capacity better, one can reduce distance and thereby carbon emission reductions. Our analysis determines the emission savings obtained by an individual transport provider who rece...

Combining pickups and deliveries in vehicle routing – An assessment of carbon emission effects

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1472159

This paper studies the effect on carbon emissions of consolidation of shipments on trucks. New positioning and communication technologies, as well as decision support systems for vehicle routing, enable better utilization of vehicle capacity, reduced travel distance, and thereby carbon emission redu...

Adaptive Large Neighborhood Search on the Graphics Processing Unit

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1395197

For computationally hard discrete optimization problems, we rely on increasing computing power to reduce the solution time. In recent years the computational capacity of the Graphics Processing Unit (GPU) in ordinary desktop computers has increased significantly compared to the Central Processing Un...

Anticipation of Emission-Driven Traffic Management in Dynamic Delivery Routing

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1371247

City authorities monitor emissions in critical regions of the city. If the emissions reach a certain threshold, city’s traffic management (TM) restricts vehicles’ access to these areas or provides alternative traffic routes. Therefore, TM changes the city’s traffic strategy. These changes impact the...

GPU parallelization of ALNS for the DCVRP

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1360725

In recent years the computational capacity of the Graphics Processing Unit (GPU) in ordinary desktop computers has increased significantly compared to the Central Processing Unit (CPU). It is interesting to explore how this alternative source of computing power can be utilized. Most investigations o...
