During this process, the company has to validate various hypotheses about its business models by adapting to uncertain and changing customer needs effectively and efficiently. This adaptation, in turn, can be supported by the concept of Software Product Lines (SPLs). SPLs reduce the time to market by deriving products for customers with changing requirements using a common set of features, structured as a feature model. Analogously, we support the process of business model adaptation by applying the engineering process of SPLs to the structure of the Business Model Canvas (BMC). We call this concept a Business Model Decision Line (BMDL). The BMDL matches business domain knowledge in the form of a feature model with customer needs to derive hypotheses about the business model together with experiments for validation. Our approach is effective by providing a comprehensive overview of possible business model adaptations and efficient by reusing experiments for different hypotheses. We implement our approach in a tool and illustrate the usefulness with an example of developing business models for a mobile application."}],"file":[{"content_type":"application/pdf","relation":"main_file","date_updated":"2020-07-14T09:33:00Z","date_created":"2020-07-14T09:33:00Z","creator":"sego","file_size":569290,"file_name":"CBI.pdf","access_level":"open_access","file_id":"17383"}],"ddc":["006"],"keyword":["Business Model Decision Line","Business Model Adaptation","Hypothesis-driven Adaptation","Software Product Line","Feature Model"],"language":[{"iso":"eng"}]},{"doi":"10.1007/978-3-030-52306-0_18","conference":{"end_date":"2020-07-08","location":"Potsdam","name":"10th International Symposium on Business Modeling and Software Design ","start_date":"2020-07-06"},"date_updated":"2022-01-06T06:52:59Z","oa":"1","author":[{"last_name":"Gottschalk","full_name":"Gottschalk, Sebastian","id":"47208","first_name":"Sebastian"},{"first_name":"Enes","full_name":"Yigitbas, Enes","id":"8447","orcid":"0000-0002-5967-833X","last_name":"Yigitbas"},{"last_name":"Engels","full_name":"Engels, Gregor","id":"107","first_name":"Gregor"}],"volume":391,"citation":{"apa":"Gottschalk, S., Yigitbas, E., &#38; Engels, G.

This adaptation is part of the research discipline of Hypotheses Engineering (HE) where customer needs can be seen as hypotheses that need to be tested iteratively by conducting experiments together with the customer. So far, modeling support and associated traceability of this iterative process are missing. Both, in turn, are important to document the adaptation to the customer needs and identify experiments that provide most evidence to the customer needs. To target this issue, we introduce a model-based HE approach with a twofold contribution: First, we develop a modeling language that models hypotheses and experiments as interrelated hierarchies together with a mapping between them. While the hypotheses are labeled with a score level of their current evidence, the experiments are labeled with a score level of maximum evidence that can be achieved during conduction. Second, we provide an iterative process to determine experiments that offer the most evidence improvement to the modeled hypotheses. We illustrate the usefulness of the approach with an example of testing the business model of a mobile application.","lang":"eng"}],"file":[{"date_updated":"2020-07-14T09:28:33Z","date_created":"2020-07-14T09:25:30Z","creator":"sego","file_size":267658,"file_id":"17380","file_name":"BMSD20.pdf","access_level":"open_access","content_type":"application/pdf","relation":"main_file"}],"publication":"Business Modeling and Software Design"},{"volume":1,"author":[{"orcid":"0000-0002-8652-9209","last_name":"Otroshi","id":"71269","full_name":"Otroshi, Mortaza","first_name":"Mortaza"},{"first_name":"Moritz","full_name":"Rossel, Moritz","last_name":"Rossel"},{"first_name":"Gerson","id":"32056","full_name":"Meschut, Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246"}],"date_created":"2020-10-20T14:49:15Z","date_updated":"2022-04-25T07:49:50Z","oa":"1","publisher":"Elsevier","doi":"10.1016/j.jajp.2020.100015","main_file_link":[{"open_access":"1"}],"title":"Stress state dependent damage modeling of self-pierce riveting process simulation using GISSMO damage model","quality_controlled":"1","intvolume":"         1","citation":{"chicago":"Otroshi, Mortaza, Moritz Rossel, and Gerson Meschut. “Stress State Dependent Damage Modeling of Self-Pierce Riveting Process Simulation Using GISSMO Damage Model.” <i>Journal of Advanced Joining Processes</i> 1 (2020). <a href=\"https://doi.org/10.1016/j.jajp.2020.100015\">https://doi.org/10.1016/j.jajp.2020.100015</a>.","ieee":"M.

The key design principle of SMBO is a substitution of the true objective function by a surrogate, which is used to propose the point(s) to be evaluated next. SMBO algorithms are intrinsically modular, leaving the user with many important design choices. Significant research efforts go into understanding which settings perform best for which type of problems. Most works, however, focus on the choice of the model, the acquisition function, and the strategy used to optimize the latter. The choice of the initial sampling strategy, however, receives much less attention. Not surprisingly, quite diverging recommendations can be found in the literature. We analyze in this work how the size and the distribution of the initial sample influences the overall quality of the efficient global optimization (EGO) algorithm, a well-known SMBO approach. While, overall, small initial budgets using Halton sampling seem preferable, we also observe that the performance landscape is rather unstructured. We furthermore identify several situations in which EGO performs unfavorably against random sampling. Both observations indicate that an adaptive SMBO design could be beneficial, making SMBO an interesting test-bed for automated algorithm design."}],"publication":"Proceedings of the Genetic and Evolutionary Computation Conference","keyword":["continuous black-box optimization","design of experiments","initial design","sequential model-based optimization"],"language":[{"iso":"eng"}],"year":"2020","title":"Initial Design Strategies and Their Effects on Sequential Model-Based Optimization: An Exploratory Case Study Based on BBOB","publisher":"Association for Computing Machinery","date_created":"2023-11-14T15:58:53Z","status":"public","type":"conference","extern":"1","_id":"48850","department":[{"_id":"819"}],"series_title":"GECCO ’20","user_id":"102979","place":"New York, NY, USA","page":"778–786","citation":{"ama":"Bossek J, Doerr C, Kerschke P.

Usually, for parallel-plate geometries, the tip-to-tip distance is used for calculation of absolute rheological values, which implies that there is no flow behind this distance. However, several studies show that this is not true. Therefore, the measuring gap needs to be corrected by adding the effective gap extension    δ    to the prescribed gap height    H    in order to obtain absolute rheological properties. In this paper, we determine the effective gap extension    δ    for different structures and fluids (Newtonian, shear thinning, and model suspensions that can be adjusted to the behavior of real fluids) and compare the corrected values to reference data. We observe that for Newtonian fluids a gap- and material-independent correction function can be derived for every measuring system, which is also applicable to suspensions, but not to shear thinning fluids. Since this relation appears to be mainly dependent on the characteristics of flow behaviour, we show that the calibration of structured measuring systems is possible with Newtonian fluids and then can be transferred to suspensions up to a certain particle content.</jats:p>","lang":"eng"}],"status":"public","type":"journal_article","publication":"Materials","article_type":"original","article_number":"467","keyword":["wall slip prevention","effective gap height","parallel-plate system","structured surfaces","model suspensions","cement paste","fresh concrete"],"language":[{"iso":"eng"}],"_id":"21948","user_id":"3959","department":[{"_id":"150"}],"year":"2020","citation":{"chicago":"Pawelczyk, Sebastian, Marieluise Kniepkamp, Steffen Jesinghausen, and Hans-Joachim Schmid. “Absolute Rheological Measurements of Model Suspensions: Influence and Correction of Wall Slip Prevention Measures.” <i>Materials</i>, 2020. <a href=\"https://doi.org/10.3390/ma13020467\">https://doi.org/10.3390/ma13020467</a>.","ieee":"S.

Following the steadily growing interest in business model innovation, software tools have shown great potential in supporting business model development and innovation. Yet, understanding the cognitive processes involved in the generation of business model ideas is an aspect of software design-knowledge that has so far been neglected. To investigate whether providing stimuli – in this case, brainstorming questions – can enhance individual creativity in this context, we conduct an exploratory experiment with over 100 participants. Our study is the first to systematically investigate the process of idea generation using a software-based business model development tool with stimuli.

During the development process, many developers focus on the multitude of product functions but neglect the business model as an equally important part. As a result, developers often fail to meet customer needs, leading to unnecessary development costs and poor market penetration. This, in turn, raises the question of how we intertwine the business model and product functions during the development process to ensure a better alignment between the two.\r\nIn this paper, we show this intertwined development by adapting the concept of Twin Peaks to the business model and product functions. Based on feature modeling as an abstraction layer, we introduce the concept of a Business Model Decision Line (BMDL) to structure the business model decisions and their relation to product functions structured in a Software Product Line (SPL). The basis of our feature models is the analysis of top listed applications in the app stores of Apple and Google. To create and modify both models, we provide an incremental feature structuring and iterative feature selection process. This combination of abstraction layer and development process supports third-party developers to build successful applications both from a business and a product perspective. \r\n"}],"date_created":"2019-09-04T21:23:07Z","publisher":"Springer International Publishing","title":"Intertwined Development of Business Model and Product Functions for Mobile Applications: A Twin Peak Feature Modeling Approach","issue":"1","year":"2019"},{"year":"2019","page":"653 - 662","intvolume":"       295","citation":{"ama":"Schemmel R, Hemsel T, Dymel C, Hunstig M, Brökelmann M, Sextro W.

Copper wire is increasingly replacing the well-established aluminium wire because of its superior electrical, thermal and mechanical properties. Copper wire processes differ significantly from aluminium processes and are more sensitive to disturbances, which reduces the range of parameter values suitable for a stable process. Disturbances can be compensated by an adaption of process parameters, but finding suitable parameters manually is difficult and time-consuming. This paper presents a physical model of the ultrasonic wire bonding process including the friction contact between tool and wire. This model yields novel insights into the process. A prototype of a multi-objective optimizing bonding machine (MOBM) is presented. It uses multi-objective optimization, based on the complete process model, to automatically select the best operating point as a compromise of concurrent objectives."}],"status":"public","_id":"9999","project":[{"grant_number":"02 PQ2210","name":"Intelligente Herstellung zuverlässiger Kupferbondverbindungen","_id":"92"}],"department":[{"_id":"151"}],"user_id":"210","keyword":["wire bonding","multi-objective optimization","process model","copper wire","self-optimization"],"language":[{"iso":"eng"}]},{"_id":"24395","user_id":"83744","department":[{"_id":"603"}],"ddc":["620"],"keyword":["Lightweight Design","Composites","Interdisciplinarity","Transdisciplinarity","V-Model."],"file_date_updated":"2021-09-14T21:34:56Z","language":[{"iso":"eng"}],"type":"conference","abstract":[{"lang":"eng","text":"In the field of lightweight design by composites, the V-Model forms the basis of inter- and\r\ntransdisciplinary collaboration and research of 13 doctoral students from different disciplines, i. e.\r\nengineering, sciences and social sciences.

The present article investigates a REM in the domain of reading performance in a sample of elementary students with special educational needs in learning (SEN-L) who received special educational support in exclusive versus inclusive settings (N = 446). In exclusive settings, SEN-L students attend special schools and are completely separated from regular students. By contrast, SEN-L students in inclusive settings attend regular schools and are educated in classes with regular students. In both settings, SEN-L students are not graded and taught based on individual learning goals, which may affect reciprocal effects between ASC and reading performance. In addition, given that special education for SEN-L students relies heavily on individual reference standards to evaluate performance, we tested individual performance growth of SEN-L students as a predictor of ASC. Analyses of a longitudinal dataset across 3rd and 4th grade revealed some cross-lagged effects and an effect of performance growth on ASC in exclusive settings in particular. The discussion focuses on the role of individualized instruction, grades, peer groups, and individual versus social reference standards for reciprocal effects between ASC and performance as well as practical implications.\r\n"}],"publication":"Learning and Individual Differences","language":[{"iso":"eng"}],"keyword":["BiLieF","Special educational needs","Learning disability","Academic selfconcept of ability","Reciprocal effects model","Inclusive education"],"year":"2018","title":"Reciprocal effects between self-concept of ability and performance: A longitudinal study of children with learning disabilities in inclusive versus exclusive elementary education","date_created":"2022-12-17T13:20:47Z","publisher":"Elsevier BV","status":"public","type":"journal_article","extern":"1","department":[{"_id":"479"}],"user_id":"95559","_id":"34498","intvolume":"        61","page":"11-20","citation":{"chicago":"Gorges, Julia, Phillip Neumann, Elke Wild, Daniela Stranghöner, and Birgit Lütje-Klose. “Reciprocal Effects between Self-Concept of Ability and Performance: A Longitudinal Study of Children with Learning Disabilities in Inclusive versus Exclusive Elementary Education.” <i>Learning and Individual Differences</i> 61 (2018): 11–20. <a href=\"https://doi.org/10.1016/j.lindif.2017.11.005\">https://doi.org/10.1016/j.lindif.2017.11.005</a>.","ieee":"J.

This autonomous behavior adaptation is made possible by software in combination with complex sensor and actuator systems and by sophisticated information processing, all of which make these systems increasingly complex. This increasing complexity makes the design process a challenging task and brings new complex possibilities for operation and maintenance. However, with the risk of increased system complexity also comes the chance to adapt system behavior based on current reliability, which in turn increases reliability. The development of such an adaption strategy requires appropriate methods to evaluate reliability based on currently selected system behavior. A common approach to implement such adaptivity is to base system behavior on different working points that are obtained using multiobjective optimization. During operation, selection among these allows a changed operating strategy. To allow for multiobjective optimization, an accurate system model including system reliability is required. This model is repeatedly evaluated by the optimization algorithm. At present, modeling of system reliability and synchronization of the models of behavior and reliability is a laborious manual task and thus very error-prone. Since system behavior is crucial for system reliability, an integrated model is introduced that integrates system behavior and system reliability.

This leads to high dropout rates. Although students’ motivation is considered a strong predictor of performance, the development of motivation during students’ transition from high school to university has rarely been investigated. Additionally, little is known about the relation of motivational aspects with other influences on study performance. The present longitudinal study addresses this research gap and examines the development of economics and management students’ study motivation. It encompasses four waves of data collected throughout the first year, using quantitative online surveys. In total, the sample consists of 820 students. Data is analysed using latent change modelling. Results indicate that students start at a higher level of intrinsic motivation compared to extrinsic motivation. The variability of the starting value of the two constructs is also differing. The analysis also shows a gradual decline in students’ motivation. Above all, the transition from secondary to higher education seems to be a driver for this decline.","lang":"eng"}],"status":"public","type":"journal_article","publication":"Higher Education","keyword":["Transition to higher education","Motivation","Longitudinal study","Socio-cultural factors","Latent change model","Switzerland"],"extern":"1","_id":"4421","user_id":"51057","department":[{"_id":"208"},{"_id":"282"}]},{"author":[{"last_name":"Kohl","full_name":"Kohl, Sergej","first_name":"Sergej"},{"first_name":"Walter","id":"21220","full_name":"Sextro, Walter","last_name":"Sextro"},{"first_name":"Sebastian","full_name":"Schulze, Sebastian","last_name":"Schulze"}],"date_created":"2019-05-27T09:13:14Z","date_updated":"2019-05-27T09:13:54Z","title":"Aspects of Flexible Viscoelastic Suspension Modeling for Frictional Rolling Contact Analysis using ADAMS","page":"1-12","citation":{"bibtex":"@inproceedings{Kohl_Sextro_Schulze_2016, place={Cyberjaya, Malaysia, 2016}, title={Aspects of Flexible Viscoelastic Suspension Modeling for Frictional Rolling Contact Analysis using ADAMS}, booktitle={The 2nd International Conference on Automotive Innovation and Green Energy Vehicle (AiGEV 2016), Cyberjaya, Malaysia, 2016.}, author={Kohl, Sergej and Sextro, Walter and Schulze, Sebastian}, year={2016}, pages={1–12} }","mla":"Kohl, Sergej, et al. “Aspects of Flexible Viscoelastic Suspension Modeling for Frictional Rolling Contact Analysis Using ADAMS.” <i>The 2nd International Conference on Automotive Innovation and Green Energy Vehicle (AiGEV 2016), Cyberjaya, Malaysia, 2016.</i>, 2016, pp. 1–12.","short":"S.

Contacting directly with road within postcard size of contact area, it is mounted and guided by the suspension system. Therefore kinematics and compliances of suspension system greatly influence the frictional coupling of tire tread elements and road surface asperities by affecting pressure and sliding velocity distribution in the contact zone. This study emphasizes the development of a numerical methodology for frictional rolling contact analysis with focus on interaction of suspension system dynamics and tire-road contact using ADAMS. For this purpose a comprehensive flexible multibody system of the multi-link rear suspension is established, where both flexible and rigid bodies are modeled to allow large displacements with included elastic effects. To meet accuracy requirements for the high frequency applications, such as road excitations, the amplitude- and frequency-dependency of rubber-metal bushings is included. Furthermore the proposed flexible viscoelastic suspension model is enhanced by a Flexible Ring Tire Model (FTire), which describes a 3D tire dynamic response and covers any road excitations by tread submodel connected to road surface model. Concerning the verification and validation procedure numerous experiments are carried out to confirm the validity and the accuracy of both the developed submodels and the entire model. The devised approach makes it possible to investigate the influence of suspension system design on dynamical rolling contact and to evaluate tire tread wear. Therefore it can be a useful tool to predict frictional power distribution within the contact area under more realistic conditions.","lang":"eng"}]},{"date_updated":"2019-05-27T09:19:49Z","date_created":"2019-05-27T09:19:20Z","author":[{"first_name":"Sebastian","last_name":"Schulze","full_name":"Schulze, Sebastian"},{"full_name":"Sextro, Walter","id":"21220","last_name":"Sextro","first_name":"Walter"},{"first_name":"Sergej","last_name":"Kohl","full_name":"Kohl, Sergej"}],"title":"Using Adequate Reduced Models for Flexible Multibody Systems of Automotive Mechatronic Systems","year":"2016","page":"1-11","citation":{"ama":"Schulze S, Sextro W, Kohl S.

To be capable of simulating large models with subassemblies and contact between bodies, reduction techniques are required, which need certain experience in the choice of parameters. This publication discusses different possibilities for the modal description of structures in flexible multibody models with application to an Adaptive Frontlighting System in ADAMS. It will be shown that mode count, assembling of structures before and after modal reduction and influence of damping parameters of particular structures and subassemblies affect the behavior of the entire system. A common reduction technique for flexible structures in multibody models is the component mode synthesis, which uses a certain number of modes for description of the modal behavior of a structure. The influence of the mode count will be shown by means of different modal descriptions of one structure that contributes to a comprehensive model. Another study will prove that modal data of subassemblies and assemblies of modal reduced single structures lead to different models. The definition of damping parameters depends on the number of structures that have been added to an assembly before modal reduction and on the number of modal reduced structures. The comparison of subassemblies and the entire model to experimental data will highlight the accuracy, computational overhead, complexity of models and modeling efficiency of the comprehensive model for the frontlighting system.","lang":"eng"}],"status":"public"}]
