Extending designated pick-up and delivery times and improving coordination of the regulations imposed by the various cities would reduce harmful emissions and would also be cheaper. In addition to this, there is much that retail chains can do themselves to improve matters.
Quak will defend his dissertation 'Sustainability of Urban Freight Transport. Retail Distribution and Local Regulations in Cities' on Thursday 20 March 2008.
For most people, urban freight transport conjures up visions of big, exhaust-spewing trucks that are a source of great nuisance. The fact that these trucks are necessary to keep the shelves filled is often conveniently forgotten. Local governments introduce all sorts of measures to minimise nuisance in cities, but in practice these measures seem to focus more on prohibiting or limiting urban retail distribution rather than contributing to a cleaner and more efficient organisation of transport. Hans Quak discovered that local governments often lack knowledge of logistical matters and as a result of this, many measures have a limited or sometimes even counterproductive effect.
Quak described in detail the many different initiatives that have been taken in the area of the development of sustainable urban retail distribution, and sought factors to explain their limited success. According to Quak, the absence of actual incentives for players who should modify their behaviour plays a major role in this. The last thing a carrier wants are additional costs, while the benefits lie elsewhere or are unseen. Quak also studied the effect of the rules most commonly used to improve urban liveability. He found that municipalities and carriers who work at different geographical levels hardly have any contact with each other. As a result of this, they know little about each other’s problems and therefore also have little understanding of the measures needed to tackle those problems.
On the basis of a case study involving 14 large retail chains, Quak concludes that the regulations which currently govern designated pick-up and delivery times are unnecessarily inefficient and often actually increase pollution. Quak demonstrates that extended and/or more limited designated pick-up and delivery times result in cleaner as well as cheaper urban freight transport. An experiment conducted with two sorts of retail chains also showed that the current rules in cities turn out differently for each carrier. “Something that resulted in a huge cost increase for one carrier, had hardly any effect on the other”. More flexible regulations could ensure that urban freight transport becomes cleaner and cheaper.
Retail chains can also implement their own measures to improve the sustainability of their operations and, at the same time, reduce the problems created by local regulations. If large chains would orchestrate the distribution of their deliveries from suppliers and combine this transport with their own shop provisioning, they would become less susceptible to designated pick-up and delivery times, for example, and could achieve significant reductions in CO2 emissions.
Hans Quak conducted his study at the Erasmus Research Institute of Management (ERIM), the combined research institute of the RSM Erasmus University and the Erasmus School of Economics of Erasmus University Rotterdam in the Netherlands. ERIM is officially accredited by the Royal Netherlands Academy of Arts and Sciences (KNAW). Over 300 researchers are affiliated to ERIM. ERIM also organises the Erasmus Doctoral Programme in Business and Management for the training of promising young scholars.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
