This paper describes the magmaOffenburg 3D simulation team trying to qualify for RoboCup 2011. While last year’s TDP focused on the tool set created for 3D simulation in this year we describe the further improvement in this tools as well as some new features we implemented focusing on heterogeneous robot models which seem to be used in RoboCup 2012.
An additional tool was written to simply generate situation-dependent strategies. Furthermore some tools, described last year, are now integrated in one single GUI to easy things up.
Existing approaches solving multi-vehicle pickup and delivery problems with soft time windows typically use common benchmark sets to verify their performance. However, there is a gap from these benchmark sets to real world problems with respect to instance size and problem complexity. In this paper we show that a combination of existing approaches together with improved heuristics is able to deal with the instance sizes and complexity of real world problems. The cost savings potential of the heuristics is compared to human dispatching plans generated from the data of a European carrier.
Seit 1997 finden jährlich Weltmeisterschaften im Roboterfußball statt. Das Ziel ist es dabei, bis 2050 eine Mannschaft aus Robotern zu stellen, die gegen den menschlichen Fußballweltmeister gewinnt. Dazu müssen die Roboter in der Lage sein, das Verhalten ihrer menschlichen Gegner einzuschätzen und ihre Entscheidungen vorauszuahnen. Während die gängigen Verfahren zur Entscheidungsfindung in unsicheren Umgebungen in der Regel auf rationalen Entscheidungen nach der Entscheidungstheorie basieren, zeigt sich, dass menschliches Entscheiden teilweise nicht dieser Rationalität folgt. Daniel Kahneman und Amos Tversky zeigten das in vielen Studien und entwickelten daraus die bekannte Prospect Theory für die Kahneman 2002 den Wirtschaftsnobelpreis erhielt. In diesem Artikel wird beschrieben, wie Extended Behavior Networks (EBNs) auf einfache Weise erweitert werden können, um menschliches Entscheidungsverhalten auch in Situationen reproduzieren zu können, die von der rationalen Entscheidungstheorie abweichen.
In previous work we [1] and other authors (e.g. [2]) have shown that agent-based systems are successful in optimizing delivery plans of single logistics companies and are meanwhile successfully productive in industry. In this paper we show that agent-based systems are particularly useful to also optimize transport across logistics companies. In intercompany optimization, privacy is of major importance between the otherwise competing companies. Some data has to be treated strictly private like the cost model or the constraint model. Other data like order information has to be shared. However, typically the amount of orders released to other companies has also to be limited. We show that our agent-based approach can be easily fine tuned to trade off privacy against the benefit of cooperation.
