Cable Tree Wiring -- Benchmarking Solvers on a Real-World Scheduling Problem with a Variety of Precedence Constraints
Koehler, Jana, Bürgler, Joseph, Fontana, Urs, Fux, Etienne, Herzog, Florian, Pouly, Marc, Saller, Sophia, Salyaeva, Anastasia, Scheiblechner, Peter, Waelti, Kai
Cable trees are widely used in industrial products to transmit energy and information between different product parts. For example, cable trees are needed in cars to automate many previously mechanical functions such as moving seats or opening windows and to add new functions such as a voice-controlled navigation or an onboard entertainment system. It is thus not surprising that for example a car like the VW Golf 7 contains 14 cable trees with a total of 1633 cables. The manufacturing of cable trees usually relies on cheap manual labour performed in low-cost countries where humans plug cables into harnesses following a wiring plan. Only few automated manufacturing solutions exist, which rely on complex robotic machines. These machines execute a sequence of wiring operations that highly qualified technicians develop by analyzing the wiring plan. With the continuing tendency towards customer-specific and resource-efficient justin-time manufacturing, smaller batch sizes of cable trees need to be manufactured requiring a frequent change of wiring plans, for which wiring sequences should be derived instantly. Scaling up human expertise to such frequent changes is simply impossible, which explains a growing interest in the intelligent automated manufacturing of cable trees. This interest is also nourished by a further miniaturization of cable harnesses, which will make their manual manufacturing impossible.
AI in Switzerland
Dessimoz, Jean-Daniel (West Switzerland University of Applied Sciences) | Koehler, Jana (University of Applied Sciences and Arts) | Stadelmann, Thilo (Zurich University of Applied Science)
Although Switzerland is a small country, it is home to many internationally renowned universities and scientific institutions. The research landscape in Switzerland is rich, and AI-related themes are investigated by many teams under diverse umbrellas. This column sheds some light on selected developments and trends on AI in Switzerland as perceived by members of the Special Interest group on Artificial Intelligence and Cognitive Science (SGAICO) organizational team, which has brought together researchers from Switzerland interested in AI and cognitive science for over 30 years.

The Fourteenth International Conference on Automated Planning and Scheduling (ICAPS-04)
Zilberstein, Shlomo, Koehler, Jana, Koenig, Sven
The Fourteenth International Conference on Automated Planning and Scheduling (ICAPS-04) was held in Canada in June of 2004. It covered the latest theoretical and empirical advances in planning and scheduling. The conference program consisted of tutorials, workshops, a doctoral consortium, and three days of technical paper presentations in a single plenary track, one day of which was jointly organized with the Ninth International Conference on Principles of Knowledge Representation and Reasoning. ICAPS-04 also hosted the International Planning Competition, including a classical track and a newly formed probabilistic track.

The Twenty-Fifth Annual German Conference on Artificial Intelligence (KI-2002)
Koehler, Jana, Lakemeyer, Gerhard
The Twenty-Fifth Annual German Conference on Artificial Intelligence (KI- 2002) was held 16 to 20 September 2003 in Aachen (Aix-La-Chapelle), Germany. KI is the main German national conference in AI, but it addresses an international audience by adopting English as the conference language and having the proceedings published in the Springer Lecture Notes in AI series.

In this regard, the presentation of the three priority programs on agent technology, sponsored by the German Science Foundation (DFG), deserve special mention. André gave an Aachen, was the general chair. This description will transform the web into a workshops preceding the main conference. Except for the workshop on other things, how lazy unfolding of He spoke, among other things, about applications of description logics, concept definitions can dramatically ongoing efforts to develop a modeling fitting with the special focus of KIspeed up the computation of least framework for web services, 2002, all others were concerned with common subsumers in practice. Sponsored by: International Society of Applied Intelligence - Organized in Cooperation with: AAAI, ACM/SIGART, CSCSI/SCEIO, ECCAI, ENNS, INNS, JSAI, NRC, and SWT IEA/AIE-2004 continues the tradition of emphasizing applications of artificial intelligence and expert/knowledge-based systems to engineering and industrial problems as well as application of intelligent systems technology to solve real-life problems.
An AI-Based Approach to Destination Control in Elevators
Koehler, Jana, Ottiger, Daniel
Not widely known by the AI community, elevator control has become a major field of application for AI technologies. Techniques such as neural networks, genetic algorithms, fuzzy rules and, recently, multiagent systems and AI planning have been adopted by leading elevator companies not only to improve the transportation capacity of conventional elevator systems but also to revolutionize the way in which elevators interact with and serve passengers. In this article, we begin with an overview of AI techniques adopted by this industry and explain the motivations behind the continuous interest in AI. In the second part, we present in more detail a recent development project to apply AI planning and multiagent systems to elevator control problems.

The AIPS-98 Planning Competition
Long, Derek, Kautz, Henry, Selman, Bart, Bonet, Blai, Geffner, Hector, Koehler, Jana, Brenner, Michael, Hoffmann, Joerg, Rittinger, Frank, Anderson, Corin R., Weld, Daniel S., Smith, David E., Fox, Maria, Long, Derek
In 1998, the international planning community was invited to take part in the first planning competition, hosted by the Artificial Intelligence Planning Systems Conference, to provide a new impetus for empirical evaluation and direct comparison of automatic domain-independent planning systems. This article describes the systems that competed in the event, examines the results, and considers some of the implications for the future of the field.
