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...

Stuck between a rock and a hard place – The pleasures of practicing OR in a contract research organization

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1354215

In this talk I will touch upon on the pleasures and hardships of being stuck between academia and industry. I will give a few examples of how OR is used at SINTEF, and address the balance between academic research and consultancy. The main topic will be research and technology development in the are...

Anticipation of Stochastic Travel Times Matrices Changes for Dynamic Vehicle Routing Induced by Emission-Driven Traffic Management

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1360722

Many European cities have experienced an increase in congestion and pollution through the growth of urban traffic. To reduce pollution and to meet a new pollution limiting EU regulation, cities can install dynamic emission-driven traffic management systems (TMs). If the air pollution at a supervised...

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...

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...

Adaptive Large Neighborhood Search on the Graphics Processing Unit

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1395194

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...
