Planning Technology Solves Rescue Missions

01.06.2007
New Danish research into search algorithms can solve complex planning problems in rescue missions in association with natural catastrophes and military operations. Associate Professor Rune Moeller Jensen from the IT University of Copenhagen has received recognition for combining two different principles within computer science which can be used to rapidly develop emergency plans which take into consideration unforeseen events.

Rune Moeller Jensen is researching automatic planning at The IT University of Copenhagen. "Planning is based on selecting and organizing activities in relation to their expected outcome to achieve specific goals. We all know planning problems from everyday life. If we, for example, are building a house, there are many activities which need to be coordinated. Such as the house's foundation needs to be completed before the walls can be built", explains Rune Moeller Jensen, adding that the same applies within IT.

"Planning technology has progressed a very long way and the number of industrial applications is increasing rapidly", says Rune Moeller Jensen. Automatic planning is used for example in air traffic control and in the planning of military rescue operations.

Automatic planning is part of an area within computer science called artificial intelligence. The goal is to develop algorithms which use descriptions of planning problems, such as a rescue operation, to return a plan of how such complex situations can be solved. Automatic planning is very challenging. "If, for example, there are 25 different things you could bring with you in a rescue helicopter such as oxygen masks, resuscitation equipment and life jackets, then there are in general 225 or more than 33 million ways to load the helicopter", explains Rune Moeller Jensen.

New Efficient Combination Creates New Opportunities

Rune Moeller Jensen’s research can be seen as providing a way to combine route planning principles with principles for automatic fault finding. "My research has combined two different but complementary principles for handling complex planning problems, developed within the computer science disciplines of artificial intelligence and formal verification", explains Rune Moeller Jensen.

Several research groups have tried to combine the two principles. However, this has been shown to be difficult. Rune Moeller Jensen has, in co-operation with American colleagues from Carnegie Mellon University, developed a method called state-set-branching, in which the two principles can be combined. "We could show that these search algorithms were more efficient than previous algorithms", he says. He explains that the new technology has been used to plan search and rescue operations for the American air force.

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
