However, as we argue in this paper, existing MAVT-based methods for measuring attribute importance weights do not fit the shopping tasks for which recommender systems are typically used. These methods assume well-trained decision makers who are willing to invest time and cognitive effort, and who are familiar with the attributes describing the available alternatives and the ranges of these attribute levels. Yet, recommender systems are most often used by consumers who are usually not familiar with the available attributes and ranges and who wish to save time and effort. Against this background, we develop a new method, based on a product configuration process, which is tailored to the characteristics of these particular decision makers. We empirically compare our method to SWING, ranking-based conjoint analysis and TRADEOFF in a between-subjects laboratory experiment with 153 participants. Results indicate that our proposed method performs better than TRADEOFF and CONJOINT and at least as well as SWING in terms of recommendation accuracy, better than SWING and TRADEOFF and at least as well as CONJOINT in terms of cognitive load, and that participants were faster with our method than with any other method. We conclude that our method is a promising option to help support consumers' decision processes in e-commerce shopping tasks.","lang":"eng"}],"extern":"1","issue":"1","publication":"European Journal of Operational Research","ddc":["000"],"user_id":"61579","volume":259,"page":"205 - 215","_id":"5671","publisher":"Elsevier","has_accepted_license":"1","status":"public","oa":"1","file_date_updated":"2018-12-13T15:06:56Z","citation":{"apa":"Scholz, M., Dorner, V., Schryen, G., &#38; Benlian, A.

Copper allows higher electrical, thermal and mechanical loads than aluminum, which currently is the most commonly used material in heavy wire bonding. This is the main driving factor for increased usage of copper in high power applications such as wind turbines, locomotives or electric vehicles. At the same time, usage of copper also increases tool wear and reduces the range of parameter values for a stable process, making the process more challenging. To overcome these drawbacks, parameter adaptation at runtime using self-optimization is desired. A self-optimizing system is based on system objectives that evaluate and quantify system performance. System parameters can be changed at runtime such that pre-selected objective values are reached. For adaptation of bond process parameters, model-based self-optimization is employed. Since it is based on a model of the system, the bond process was modeled. In addition to static model parameters such as wire and substrate material properties and vibration characteristics of transducer and tool, variable model inputs are process parameters. Main simulation result is bonded area in the wiresubstrate contact. This model is then used to find valid and optimal working points before operation. The working point is composed of normal force and ultrasonic voltage trajectories, which are usually determined experimentally. Instead, multiobjective optimalization is used to compute trajectories that simultaneously optimize bond quality, process duration, tool wear and probability of tool-substrate contacts. The values of these objectives are computed using the process model. At runtime, selection among pre-determined optimal working points is sufficient to prioritize individual objectives. This way, the computationally expensive process of numerically solving a multiobjective optimal control problem and the demanding high speed bonding process are separated. To evaluate to what extent the pre-defined goals of self-optimization are met, an offthe- shelf heavy wire bonding machine was modified to allow for parameter adaptation and for transmitting of measurement data at runtime. This data is received by an external computer system and evaluated to select a new working point. Then, new process parameters are sent to the modified bonding machine for use for subsequent bonds. With these components, a full self-optimizing system has been implemented."}],"quality_controlled":"1","project":[{"_id":"92","grant_number":"02 PQ2210","name":"Intelligente Herstellung zuverlässiger Kupferbondverbindungen"}],"publication":"IEEE 66th Electronic Components and Technology Conference","citation":{"bibtex":"@inproceedings{Meyer _Unger_Althoff_Sextro_Brökelmann_Hunstig_Guth_2016, title={Reliable Manufacturing of Heavy Copper Wire Bonds Using Online Parameter Adaptation}, DOI={<a href=\"https://doi.org/10.1109/ECTC.2016.215\">10.1109/ECTC.2016.215</a>}, booktitle={IEEE 66th Electronic Components and Technology Conference}, author={Meyer , Tobias and Unger, Andreas and Althoff, Simon and Sextro, Walter and Brökelmann, Michael and Hunstig, Matthias and Guth, Karsten}, year={2016}, pages={622–628} }","ama":"Meyer  T, Unger A, Althoff S, et al.

To do so, they generally select among several pre-defined working points. A common method to determine working points for a mechatronic system is to use model-based multiobjective optimization. It allows finding compromises among conflicting objectives, called objective functions, by adapting parameters. To evaluate the system behavior for different parameter sets, a model of the system behavior is included in the objective functions and is evaluated during each function call. Intelligent mechatronic systems also have the ability to adapt their behavior based on their current reliability, thus increasing their availability, or on changed safety requirements; all of which are summed up by the common term dependability. To allow this adaptation, dependability can be considered in multiobjective optimization by including dependability-related objective functions. However, whereas performance-related objective functions are easily found, formulation of dependability-related objective functions is highly system-specific and not intuitive, making it complex and error-prone. Since each mechatronic system is different, individual failure modes have to be taken into account, which need to be found using common methods such as Failure-Modes and Effects Analysis or Fault Tree Analysis. Using component degradation models, which again are specific to the system at hand, the main loading factors can be determined. By including these in the model of the system behavior, the relation between working point and dependability can be formulated as an objective function. In our work, this approach is presented in more detail. It is exemplified using an actively actuated single plate dry clutch system. Results show that this approach is suitable for formulating dependability-related objective functions and that these can be used to extend system lifetime by adapting system behavior."}],"quality_controlled":"1","page":"46-53","_id":"9885","language":[{"iso":"eng"}],"user_id":"55222","doi":"10.1016/j.protcy.2014.09.033","volume":15,"title":"Method to Identify Dependability Objectives in Multiobjective Optimization Problem","status":"public","year":"2014","author":[{"full_name":"Meyer , Tobias","last_name":"Meyer ","first_name":"Tobias"},{"first_name":"Christoph","last_name":"Sondermann-Wölke","full_name":"Sondermann-Wölke, Christoph"},{"full_name":"Sextro, Walter","first_name":"Walter","last_name":"Sextro","id":"21220"}],"date_updated":"2019-09-16T10:22:04Z","intvolume":"        15"},{"date_created":"2019-07-10T11:23:00Z","type":"conference","keyword":["Linux","cache storage","embedded systems","granular computing","multiprocessing systems","reconfigurable architectures","Leon3 SPARe processor","custom logic events","evolvable-self-adaptable processor cache","fine granular profiling","integer unit events","measurement infrastructure","microarchitectural events","multicore embedded system","perf_event standard Linux performance measurement interface","processor properties","run-time reconfigurable memory-to-cache address mapping engine","run-time reconfigurable multicore infrastructure","split-level caching","Field programmable gate arrays","Frequency locked loops","Irrigation","Phasor measurement units","Registers","Weaving"],"department":[{"_id":"78"}],"publication":"2014 {IEEE} Intl.

With increasing storage demands and emerging storage services the question how to schedule storage jobs becomes more and more interesting. Since such scheduling problems are often in the class NP-complete an exact computation is not feasible in practice. On the other hand an approximation to the optimal solution can easily be found by means of using heuristics. The problem with this attempt is that the suggested solution may not be exactly optimal and is thus less satisfying. Considering the two above mentioned solution approaches one can clearly find a trade-off between the optimality of the solution and the efficiency to get to a solution at all. This work proposes to apply and combine heuristics in optimization to gain from both of their benefits while reducing the problematic aspects. Following this method it is assumed to get closer to the optimal solution in a shorter time compared to a full optimization."}],"extern":"1","language":[{"iso":"eng"}],"author":[{"full_name":"Finkbeiner, Josef","last_name":"Finkbeiner","first_name":"Josef"},{"full_name":"Bodenstein, Christian","last_name":"Bodenstein","first_name":"Christian"},{"id":"72850","full_name":"Schryen, Guido","first_name":"Guido","last_name":"Schryen"},{"full_name":"Neumann, Dirk","first_name":"Dirk","last_name":"Neumann"}],"year":"2010","title":"Applying heuristic methods for job scheduling in storage markets","date_updated":"2022-01-06T07:02:32Z"},{"_id":"9763","language":[{"iso":"eng"}],"page":"1 -6","doi":"10.1109/RAMS.2010.5448080","user_id":"55222","publication_identifier":{"issn":["0149-144X"]},"author":[{"full_name":"Sondermann-Wölke, Christoph","first_name":"Christoph","last_name":"Sondermann-Wölke"},{"last_name":"Geisler","first_name":"Jens","full_name":"Geisler, Jens"},{"id":"21220","last_name":"Sextro","first_name":"Walter","full_name":"Sextro, Walter"}],"title":"Increasing the reliability of a self-optimizing railway guidance system","year":"2010","status":"public","date_updated":"2022-01-06T07:04:19Z","date_created":"2019-05-13T10:35:39Z","department":[{"_id":"151"}],"keyword":["availability","dependability concept","multilevel dependability concept","railway vehicle","reliability","self optimizing active guidance system","self optimizing railway guidance system","situation classification","system behavior monitoring","optimal control","railways","reliability theory","self-adjusting systems"],"type":"conference","citation":{"ieee":"C.

These systems are able to adapt their objectives and their behavior according to the current situation and influences autonomously. This behavior adaptation is non-deterministic and hence self-optimization is a risk to the system, e.g. if the result of the self-optimization process does not match the suddenly changed situation. In contrary, self-optimization could be used to increase the dependability by pursuing objectives like reliability and availability. In our preceding publications we introduced the so called multi-level dependability concept to cope with this new kind of systems (cf. [6]). This concept comprises the monitoring of the system behavior, the classification of the current situation, and the selection of the appropriate measure, if reliability limits are exceeded. In this paper we present for the first time experimental results. The dependability concept is implemented in the self-optimizing active guidance system of a railway vehicle. The test drives illustrate clearly that the proposed concept is able to cope with, e.g., sensor failures, and is able to increase the reliability and availability of the active guidance module."}]},{"user_id":"44006","doi":"10.1109/WPNC.2010.5650745","main_file_link":[{"url":"https://groups.uni-paderborn.de/nt/pubs/2010/BeWaPeHa10.pdf","open_access":"1"}],"page":"128-134","_id":"11726","language":[{"iso":"eng"}],"date_updated":"2022-01-06T06:51:07Z","title":"Barometric height estimation combined with map-matching in a loosely-coupled Kalman-filter","year":"2010","status":"public","author":[{"full_name":"Bevermeier, Maik","last_name":"Bevermeier","first_name":"Maik"},{"full_name":"Walter, Oliver","last_name":"Walter","first_name":"Oliver"},{"first_name":"Sven","last_name":"Peschke","full_name":"Peschke, Sven"},{"id":"242","first_name":"Reinhold","last_name":"Haeb-Umbach","full_name":"Haeb-Umbach, Reinhold"}],"type":"conference","keyword":["altitude measurement unit","barometers","barometric altimeter","barometric error Kalman filter","barometric height estimation","direct cosine matrix","global positioning system","Global Positioning System","GPS device","height information","height measurement","inertial measurement unit","Kalman filters","loosely-coupled error state space Kalman filter","loosely-coupled Kalman-filter","map matching","robust information","robust location estimation","sensor fusion","topographic map information","vertical user position"],"department":[{"_id":"54"}],"oa":"1","date_created":"2019-07-12T05:27:04Z","abstract":[{"lang":"eng","text":"In this paper we present a robust location estimation algorithm especially focused on the accuracy in vertical position. A loosely-coupled error state space Kalman filter, which fuses sensor data of an Inertial Measurement Unit and the output of a Global Positioning System device, is augmented by height information from an altitude measurement unit. This unit consists of a barometric altimeter whose output is fused with topographic map information by a Kalman filter to provide robust information about the current vertical user position. These data replace the less reliable vertical position information provided the GPS device. It is shown that typical barometric errors like thermal divergences and fluctuations in the pressure due to changing weather conditions can be compensated by the topographic map information and the barometric error Kalman filter. The resulting height information is shown not only to be more reliable than height information provided by GPS. It also turns out that it leads to better attitude and thus better overall localization estimation accuracy due to the coupling of spatial orientations via the Direct Cosine Matrix.

We investigated the role of motor action in this context. In the first two experiments, using a one-shot implicit change detection paradigm, participants responded to unperceived changes either with an action (jabbing the screen at the guessed location of a change) or with words (verbal report), and sat either 60 cm or 300 cm (with a laser pointer) away from the display. Our observers guessed the locations of changes at a reachable distance better with an action than with a verbal judgment. At 300 cm, beyond reach, the motor advantage disappeared. In experiment 3, this advantage was also unavailable when participants sat at a reachable distance but responded with hand-held laser pointers near their bodies. We conclude that a motor system specialized for real-time visually guided behavior has access to additional visual information.

For this, we combine the native speed of an abstract real-time operating system (RTOS) model in SystemC with dynamic binary translation for fast Instruction Set Simulation (ISS) by QEMU. In order to support stepwise RTOS software refinement from system level to the target software, each task can be separately migrated between the native execution and the ISS. By adapting the dynamic binary translation approach to an efficient but yet very accurate synchronization scheme the overhead of QEMU user mode execution is only factor two compared to native SystemC. Furthermore, the simulation speed increases almost linearly according to the utilization of the task set abstracted by the native execution. Hereby, the simulation time can be considerably reduced by cosimulating just a subset of tasks on QEMU.","lang":"eng"}],"date_created":"2023-01-17T11:01:30Z","place":"Dordrecht","type":"conference","keyword":["Application Programming Interface     User Mode     Kernel Space     System Level Design     Mixed Level"],"department":[{"_id":"672"}],"year":"2010","status":"public","title":"A Mixed Level Simulation Environment for Stepwise RTOS Software Refinement","publication_identifier":{"isbn":["978-3-642-15233-7"]},"author":[{"first_name":"Markus","last_name":"Becker","full_name":"Becker, Markus"},{"full_name":"Zabel, Henning","first_name":"Henning","last_name":"Zabel"},{"id":"16243","full_name":"Müller, Wolfgang","last_name":"Müller","first_name":"Wolfgang"}],"conference":{"name":"IFIP Working Conference on Distributed and Parallel Embedded Systems (DIPES 2010)"},"date_updated":"2023-01-17T11:03:00Z","language":[{"iso":"eng"}],"_id":"37046","publisher":"Springer Verlag","user_id":"5786","doi":"10.1007/978-3-642-15234-4_15","editor":[{"first_name":"L.","last_name":"Kleinjohann","full_name":"Kleinjohann, L."},{"last_name":"Kleinjohann","first_name":"B.","full_name":"Kleinjohann, B."}]},{"_id":"11723","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://groups.uni-paderborn.de/nt/pubs/2009/BePeHa09.pdf","open_access":"1"}],"page":"235-242","doi":"10.1109/WPNC.2009.4907833","user_id":"44006","author":[{"first_name":"Maik","last_name":"Bevermeier","full_name":"Bevermeier, Maik"},{"full_name":"Peschke, Sven","last_name":"Peschke","first_name":"Sven"},{"full_name":"Haeb-Umbach, Reinhold","first_name":"Reinhold","last_name":"Haeb-Umbach","id":"242"}],"title":"Robust vehicle localization based on multi-level sensor fusion and online parameter estimation","status":"public","year":"2009","date_updated":"2022-01-06T06:51:07Z","date_created":"2019-07-12T05:27:01Z","oa":"1","department":[{"_id":"54"}],"type":"conference","keyword":["covariance matrices","expectation-maximisation algorithm","expectation-maximization algorithm","global positioning system","Global Positioning System","GPS","inertial measurement unit","interacting multiple model approach","Kalman filters","multilevel sensor fusion","narrow street canyons","narrow tunnels","online parameter estimation","parameter estimation","road vehicles","robust vehicle localization","sensor fusion","state noise covariances","time-variant multilevel Kalman filter","vehicle tracking algorithm"],"citation":{"ama":"Bevermeier M, Peschke S, Haeb-Umbach R.

After individual Kalman filtering of GPS and IMU measurements the estimates of the orientation of the vehicle are combined in an optimal manner to improve the robustness towards drift errors. The tracking algorithm incorporates the estimation of time-variant covariance parameters by using an iterative block Expectation-Maximization algorithm to account for time-variant driving conditions and measurement quality. The proposed system is compared to an interacting multiple model approach (IMM) and achieves improved localization accuracy at lower computational complexity. Furthermore we show how the joint parameter estimation and localizaiton can be conducted with streaming input data to be able to track vehicles in a real driving environment."}],"date_created":"2019-07-12T05:27:02Z","keyword":["computational complexity","expectation-maximisation algorithm","Global Positioning System","inertial measurement unit","inertial navigation","interacting multiple model","iterative block expectation-maximization algorithm","Kalman filters","multi-stage Kalman filter","parameter estimation","road vehicles","vehicle positioning","vehicle tracking"],"type":"conference","department":[{"_id":"54"}],"oa":"1","title":"Joint Parameter Estimation and Tracking in a Multi-Stage Kalman Filter for Vehicle Positioning","year":"2009","status":"public","author":[{"full_name":"Bevermeier, Maik","last_name":"Bevermeier","first_name":"Maik"},{"last_name":"Peschke","first_name":"Sven","full_name":"Peschke, Sven"},{"full_name":"Haeb-Umbach, Reinhold","last_name":"Haeb-Umbach","first_name":"Reinhold","id":"242"}],"date_updated":"2022-01-06T06:51:07Z","page":"1-5","main_file_link":[{"open_access":"1","url":"https://groups.uni-paderborn.de/nt/pubs/2009/BePeHa09-1.pdf"}],"language":[{"iso":"eng"}],"_id":"11724","user_id":"44006","doi":"10.1109/VETECS.2009.5073634"},{"language":[{"iso":"eng"}],"_id":"11881","page":"195-202","main_file_link":[{"open_access":"1","url":"https://groups.uni-paderborn.de/nt/pubs/2009/PeBeHa09-1.pdf"}],"user_id":"44006","doi":"10.1109/WPNC.2009.4907827","author":[{"full_name":"Peschke, Sven","last_name":"Peschke","first_name":"Sven"},{"first_name":"Maik","last_name":"Bevermeier","full_name":"Bevermeier, Maik"},{"full_name":"Haeb-Umbach, Reinhold","first_name":"Reinhold","last_name":"Haeb-Umbach","id":"242"}],"status":"public","title":"A GPS positioning approach exploiting GSM velocity estimates","year":"2009","date_updated":"2022-01-06T06:51:11Z","date_created":"2019-07-12T05:30:04Z","department":[{"_id":"54"}],"oa":"1","keyword":["cellular radio","distance measurement","global positioning system","Global Positioning System","global system for mobile communications","GPS positioning approach","GSM velocity","gyroscopes","gyroscope sensor","inertial navigation","inertial navigation system","odometer","sensor fusion system architecture","sensors"],"type":"conference","citation":{"ieee":"S.

Notably during times when the GPS signal has a poor quality, e.g. due to the lack of a sufficiently large number of visible satellites, the INS, which may consist of a gyroscope and an odometer, will lead to improved positioning accuracy. In this paper we show how velocity information obtained from GSM (global system for mobile communications) signalling, rather than from a tachometer, can be used together with a gyroscope sensor to support localization in the presence of temporarily unavailable GPS data. We propose a sensor fusion system architecture and present simulation results that show the effectiveness of this approach."}]}]
