What a wonderful opportunity to enrich our social and intellectual capital in the historic and artisic city of Bonn. I would like to congratulate everyone involved in laying the foundations for what promises to be an excellent conference. It will be the third EURO conference in a row to attract a record breaking number of papers, for the first time exceeding 2000. EURO’s overarching objectives are to advance knowledge, interest and education in OR and this growth is encouraging evidence of continuing achievement. This is particularly so in the current challenging economic times – but may also be a reflection of the benefit that OR can bring to organisations in such a climate, helping them to define their core values, identify and achieve “value for money” and, as the conference theme reminds us, to create competitive advantage. The conference is an opportunity for us to celebrate success. We will do this in many ways, such as the conferment of a range of EURO awards, including the new medal for distinguished service to EURO. However, the true success of the confe- rence will be realised through the active participation of all of us – I hope that everyone will leave feeling personally enriched, I know that the discipline of OR will be. Valerie Belton President of EURO I2 BOOK OF ABSTRACT 23RD EUROPEAN CONFERENCE ON OPERATIONAL RESEARCH Bonn, July 5 - 8, 2009 WELCOME Dear participant, Welcome to the EURO conference 2009. We are happy to have you here in Bonn! The first meeting in this series took place in Brussels, way back in 1975. At that time the meeting consisted of 120 presen- tations that attracted 500 participants. A lot of time has passed since then, and the present conference is already the 23rd meeting in the series. And the conference has grown beyond all our expectations: This year we will have over 2000 presen- tations and over 2200 participants! This makes EURO'2009 by far the largest EURO conference ever, and we are proud to host far more than 800 Non-European delegates in Bonn. Because of this large number of delegates, the Programme Com- mittee decided that regular sessions will be allotted 80 minutes (instead of the 90 minutes at previous conferences). Future organisers will have to find other solutions to create a pleasant schedule, and perhaps this is the right moment for extending the conference to a four-day-event. Over the years the EURO conferences have not only grown with respect to volume. They also have expanded into new areas of application, and they have opened up into new research directions. For example: 20 years ago EURO still did not cover the area of computational biology. Or: 10 years ago EURO still did not cover the area of algorithmic game theory. This permanent development and permanent adaption to new challenges (we could perhaps also say: this preservation of favourable variations, and the destruction of injurious variations) is the principal factor of our strength, and it is the key to our future success. The conference theme is OR creating competitive advantage, and a number of our keynote speakers will develop their ideas on this. Furthermore, you will find that several of the streams and many of the contributed talks are centered around this theme. And finally we would like to thank you, dear participant, personally for your contribution in making this conference a big suc- cess. We hope that while you are experiencing the exciting atmosphere of this event, you will gain many new insights and learn about the fascinating new developments in Operations Research.

  • A Cognitive Model of Strategies for Cardinal Direction Judgments
    SPATIAL COGNITION AND COMPUTATION, 7(2), 179–212 Copyright © 2007, Lawrence Erlbaum Associates, Inc. A Cognitive Model of Strategies for Cardinal Direction Judgments Leo Gugerty and William Rodes Psychology Department, Clemson University, Clemson, SC ABSTRACT Previous research has identified a variety of strategies used by novice and experienced navigators in making cardinal direction judgments (Gugerty, Brooks, & Treadaway, 2004). We developed an ACT-R cognitive model of some of these strategies that instantiated a number of concepts from research in spatial cognition, including a visual-short-term-memory buffer overlaid on a perceptual buffer, an egocentric ref- erence frame in visual-short-term-memory, storage of categorical spatial information in visual-short-term-memory, and rotation of a mental compass in visual-short-term- memory. Response times predicted by the model fit well with the data of two groups, college students (N D 20) trained and practiced in the modeled strategies, and jet pilots (N D 4) with no strategy training. Thus, the cognitive model seems to pro- vide an accurate description of important strategies for cardinal direction judgments. Additionally, it demonstrates how theoretical constructs in spatial cognition can be applied to a complex, realistic navigation task. Keywords: cardinal directions, cognitive modeling, visual short term memory. INTRODUCTION This project focuses on understanding the cognitive processes and structures people use in making a particular type of navigational judgment—using a map to determine the cardinal direction between two objects in the environment. We first developed a cognitive model of some of the strategies people use in making this type of cardinal direction judgment.

  • Summarizing GPS Trajectories by Salient Patterns
    Summarizing GPS trajectories by salient patterns Stefanie ANDRAE1 und Stephan WINTER2 1 Technikum Kaernten, Villach, Austria 2 Department of Geomatics, The University of Melbourne, Australia Abstract Individuals can easily record their movements in space nowadays with personal navigation devices based on the GPS technology. The recorded data contain in principle detailed information about a traveled route. The information inherent in the data could be used to automatically generate travel diaries. In this paper we study a method to summarize and to symbolize a route according to the cardinal and egocentric directions traveled. The same symbolization method can be applied to other parameters of tracking data, e.g. speed. 1 Introduction For the purpose of human mobile navigation, small, low cost GPS receivers have become available. Affordable prices and reasonable accuracy have increased their use, e.g., in car navigation systems, or for outdoor activities. These devices are able to produce trajectories from quasi-continuous positioning. A trajectory consists of a sequence of time-stamped position and orientation parameters, and represents a travel history of the moving individual that is at least machine readable. Current tracking software can post-process these trajectories. However, tracking software structures and communicates the information about the traveled route in a way that requires some expertise for human analysis and interpretation. Communication in forms close to human cognitive concepts of spatial behavior is still beyond the capabilities of current systems. Being interested in the story in trajectory data, we aim towards an automatic generation of a human-readable travel diary. In principle, a travel diary links geometric knowledge acquired from trajectories with many other resources that provide context, e.g., personal context from a user profile, situational context from the environment, the time of the day, the type of activity, and so on.

  • Navigating the Compass
    Navigating the Compass How does a compass work? Most of us have a compass somewhere in our house, but may never use it! A compass is a tool to help you get from one place to another (or navigate) by indicating direction. This happens when a magnetized needle lines up with the magnetic poles of the Earth, which are at the North and South of our planet (like the North pole and the South pole). Think of the way a magnet sticks to your fridge – the magnet is drawn towards the fridge, the same way as this needle is drawn towards the North magnetic pole. Some birds even use this magnetic field to know which way to migrate. Navigators use the four cardinal directions, North, South, East and West to make their way from 1 point to another. Today, magnetized needles you see will have a red or white line that lets you know which ways is North. North – East – South – West are the directions of your compass. I remember the order by going around the compass clockwise while saying Never – Eat – Soggy – Waffles! History of the Compass Scientists and historians believe that the Ancient Greeks understood magnetism, and that the Chinese may have begun magnetizing needles over 2,000 years ago. The first compasses were made from sticking a magnetized needle onto a wine cork and then letting it float in water. The needle would spin and point towards North. Before these compasses were widely used in travel, people relied on the sun (which rises in the East and sets in the West), the stars and major landmarks to navigate.

  • 3. Compass and Navigational Gps
    3. COMPASS AND NAVIGATIONAL GPS Two different methods of navigation will be used while you conduct monitoring. You will use a navigational GPS to locate transect start points, keep track of meters walked, check the Juno grab for validity, and return to your vehicle from the transect. A compass will be used to set and hold the correct bearing as you walk, and to report azimuth and bearing. The integrated Juno GPS is not for navigation; it is used solely to transfer location data to the collection system. The goal of Compass and Navigational GPS training is to enable you to confidently and correctly apply your existing knowledge of GPS and compass navigation to distance sampling. It is expected that you already have a basic understanding of how to navigate with a compass and a standard recreational grade GPS unit. These skills are crucial to collecting data, as well as to your personal safety and the safety of those around you. Objective 1: Basic understanding of GPS. Navigational GPSs are provided by each monitoring team, so unit set up, operation, and maintenance are the responsibility of each team. Emphasis in USFWS training is on application to distance sampling for desert tortoises. Standard: Understand GPS basics, including what GPS is and how it works Standard: Understand coordinate systems and how they are applied to GPS Standard: Understand the importance of GPS signal strength Standard: Correctly utilize GPS in the context of distance sampling surveys Objective 2: Basic understanding of compass use. Compasses are provided by each monitoring team, so compass set up, operation, and maintenance are the responsibility of each team.

  • Where Is North? the Compass Can Tell Us
    WHERE IS NORTH? THE COMPASS CAN TELL US... Objectives The students will: Build a compass. Determine the direction of north, south, east, and west. Standards and Skills Science Science as Inquiry Physical Science Earth and Space Science Science and Technology Science Process Skills Observing Inferring Making Models Mathematics Connections Verifying and Interpreting Results Prediction Background The compass has been used for centuries as a tool for navigation. It is an instrument that aligns a free pivoting bar magnet (called the NORTH needle) in Earth's magnetic field. POLE Since the invisible lines of the magnetic field are oriented in a north/south direction, the needle will orient itself in a north/south direction. The other cardinal points of the compass (east, west, and south) are defined in relation to north. Pilots use a compass to determine direction when flying airplanes. Boaters, hikers, and hunters are examples of other people who rely POLE on compasses.
