  abstract     = {{The development of today’s technical products (e.g., in automation) is characterized by high customer expectations regarding the product individualization, which causes a wide range of product variants. Original equipment manufacturers (OEMs) can apply classical approaches from product line engineering, like feature modeling, to cope with the variability and the induced development complexity. Our tool support for feature models integrates a variety of feature model extensions like feature attributes and properties, logical constraints between features and feature properties, and the distinction between features and feature realizations. Furthermore, technical products have geometrical dimensions. The OEM specifies Computer Aided Design (CAD) models to consider these geometric dimensions and to virtually layout particular product variants. Geometric assembly constraints specify how parts of the product can be arranged in a CAD model. However, a potential product customer cannot configure an individual product variant and virtually layout this variant in the same software tool since the respective information stems from different sources. In order to cope with this problem, we present in this paper an extension of our tool support for feature models to specify geometric assembly constraints. Based on the proposed extension, we outline our research roadmap to consider these constraints in an online shop of an e-commerce system, in which a potential customer shall be able to configure a product variant and to virtually layout it according to the assembly constraints.

  abstract     = {{Cyber-physical systems like self-driving cars are highly complex and safety-critical. This results in a great number of safety requirements that have different levels of criticality. In automotive, the criticality is categorized in Automotive Safety Integrity Levels (ASIL). As a high ASIL causes high development effort, the goal is to develop most subsystems with lower ASIL requirements. To achieve this ASIL tailoring, subsystems need to be separated or redundantly implemented. These safety measures are usually integrated late in the development process and thus cause costly development iterations. In this paper, we present a systematic, tool-supported ASIL tailoring process for the requirements analysis phase. It is applied on formal safety requirements and automatically generated fault trees for a functional view of the system. The process supports early planning of safety efforts for mixed-criticality systems and avoids costly late development iterations.}},

  abstract     = {{In verschiedenen Unternehmen wird mit Anforderungen unterschiedlich umgegangen. Je nach Größe, Branche und Unternehmenskultur ist das Thema Requirements Engineering (RE) mal weniger, mal mehr etabliert. In einigen Unternehmen wird es als lästige Zusatzaufgabe betrachtet, während andere Unternehmen ganze Abteilungen mit RE als Kernkompetenz betreiben. RE wird allerdings in jedem Projekt - bewusst oder unbewusst - durchgeführt! RE ist die Basis für den weiteren Entwicklungsprozess, die Validierung/Verifikation und die Plan- und Messbarkeit des Projekts. Darüber hinaus können Fehler, die auf Anforderungsebene gefunden werden, weniger aufwendig und somit günstiger behoben werden als in späteren Entwicklungsphasen. Am Fraunhofer IEM beraten wir Unternehmen und erforschen neue Methoden bezüglich der Entwicklung von intelligenten technischen Systemen. In diesem Artikel berichten wir über unsere Erfahrungen aus Projekten, in denen wir Unternehmen aus verschiedenen Branchen und mit unterschiedlichem RE-Reifegrad zwecks Leistungssteigerung des RE begleitet haben. Auf Basis dieser Projekterfahrungen zeigen wir Wege auf, wie der Stand des RE mittels eines Reifegradmodells im eigenen Unternehmen verbessert werden kann.}},

  abstract     = {{The development of software-intensive technical systems involves several engineering disciplines like mechanical, electrical, control, and particularly software engineering. Model-based Systems Engineering (MBSE) coordinates these disciplines throughout the development by means of discipline-spanning processes and a system model. Such a system model provides a common understanding of the system under development and serves as a starting point for the discipline-specific development. An integral part of MBSE is the requirements engineering on the system level. However, these requirements need to be refined for the discipline-specific development to start, e.g., into specific requirements for the embedded software. Since existing MBSE approaches lack support for this refinement step, we conceived in previous work a systematic transition from MBSE to model-based software requirements engineering. We automated the steps of the transition where possible, in order to avoid error-prone and time-consuming manual tasks. In this paper, we extend this approach with support for subsequent process iterations and provide an algorithm for the automated steps. We illustrate the approach and perform a case study with an example of an automotive embedded system.}},

We introduce congestion games with mixed objectives to model network scenarios in which players seek to optimize for latency and bandwidths alike.

For games that do not possess PNE we give bounds on the approximation ratio of approximate pure Nash equilibria.}},

  abstract     = {{Recent literature reports concerns about implausibly high Overall ratings in the sharing economy, which undermines the credibility of this rating as a quality signal. This study empirically investigates the relationship between quality and price, commonly captured by the Value dimension in multidimensional rating systems, to reveal whether reviewers form a perception of quality that they then express in the Value dimension, rather than in the Overall rating. We test our hypotheses on a comprehensive panel dataset for 14,859 Airbnb listings in New York. Our preliminary empirical findings show that an increase in price leads to a significant and substantial decrease in the Value rating, suggesting that Value ratings can offer a valuable source of information for potential buyers in addition to the supposedly inflated Overall rating. Moreover, this mechanism has substantial implications for potential buyers who seek to evaluate a listing’s quality and for a seller’s price setting. }},
