Dynamische Modellierung nationaler Aluminiumflüsse zur Abschätzung zukünftiger Sekundärrohstoffpotenziale Dynamic modelling of national aluminium flows in order to evaluate future secondary resource potentials

چکیده
The continuous increasing consumption of metals during the last decades caused a considerable growth of anthropogenic stocks. But, knowledge regarding quantity, quality and availability of material from these stocks is still quite limited. This study aims at analysing anthropogenic aluminium (Al) stocks and flows in Austria utilising a dynamic material flow model. The amount of Al currently store in in-use stocks is about 360 kg/cap, total annual old scrap generation amounts to approx. 12 kg/cap and year. Through the combination of the existing dynamic material flows model with forecasts on future Al consumption the prospective trend of old scrap as well as the degree of self-supply from secondary resources is calculated.

Modellierung von dynamischen Zielen in Agentensystemen mit Ziel/Transitions-Netzen
Die geeignete Darstellung von Zielen ist ein wichtiger Aspekt bei der Modellierung von Agentensystemen. Ziele stellen mentale Zustände eines Agenten dar und können sich zur Laufzeit ändern (dynamische Ziele). Sie sind deshalb als dynamische Elemente auf der Modellebene abzubilden. Für die Modellierung von Agentensystemen mit dynamischen Zielen wird in dieser Arbeit die Klasse der Ziel/Transitio...

Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...
متن کاملDynamic modelling of hardness changes of aluminium nanostructure during mechanical ball milling process
In this research, the feasibility of using mathematical modelling in the ball milling process has been evaluated to verify the hardness changes of an aluminium nanostructure. Considering the model of normal force displacement (NFD), the radius of elastic-plastic and normal displacement of two balls were computed by applying analytical modelling and coding in MATLAB. Properties of balls and alum...
