text: In diesem Beitrag wird ein Ansatz vorgestellt, welcher die Bewertung des Risikos
von Anforderungsänderungen in der Entwicklung mechatronischer Systeme ermöglicht.
Ausgehend von einer Anforderungsliste werden die Wechselwirkungen in einer Requirements
Structure Matrix (RSM) teilautomatisch erfasst. Parallel werden Anforderungen
in Bezug auf ihren Ursprung („Einflussbereich“) kategorisiert und darauf aufbauend
priorisiert. Diese Priorisierung basiert auf dem Veränderungsrisiko und wird durch
die drei Kriterien „Dynamik“, „Unsicherheit der Wissensbasis“ und „Relevanz für
den Entwicklungsprozess“ charakterisiert. Das Vorgehen wird anhand strukturierter
Interviews mit Projektleitern und Entwicklern und der Fallstudie eines Pedelecs
als mechatronischem System validiert. Durch die Anwendung der Methode können disziplinübergreifende
Abhängigkeiten von Anforderungen zur Reduktion von Iterationen in der Entwicklung
mechatronischer Systeme – wie dem Pedelec – berücksichtigt werden.

text: Due to the great popularity of the Fused Deposition Modeling (FDM) process,
the material market is growing. In particular, processing of high-temperature
materials such as PEEK is demanding. The aim of the investigations is to test
different PEEK materials regarding their processability in the FDM process. An
unreinforced PEEK, a thermally conductive PEEK as well as a carbon fiber reinforced
PEEK are investigated. The processability is assessed with the help of the weld
seam strength. The assessment of the weld seam strength is carried out by building
tests. For this purpose, a special method developed at the DMRC is used. In addition,
a welding width factor between the strands deposited on each other is calculated
and compared. Finally, a welding factor is determined to enable the comparison
between the different materials. With this procedure, the influence of varying
nozzle and build chamber temperatures on the achievable weld seam strengths is
evaluated.

text: "As 5G and network function virtualization (NFV) are maturing, it becomes
crucial to demonstrate their feasibility and benefits by means of vertical scenarios.
While 5GPPP has identified smart manufacturing as one of the most important vertical
industries, there is still a lack of specific, practical use cases. \r\n\r\nUsing
the experience from a large-scale manufacturing company, Weidm{\\\"u}ller Group,
we present a detailed use case that reflects the needs of real-world manufacturers.
We also propose an architecture with specific network services and virtual network
functions (VNFs) that realize the use case in practice. As a proof of concept,
we implement the required services and deploy them on an emulation-based prototyping
platform. Our experimental results indicate that a fully virtualized smart manufacturing
use case is not only feasible but also reduces machine interconnection and configuration
time and thus improves productivity by orders of magnitude."

text: "In the last years, store-oriented software ecosystems are gaining\r\nmore
and more attention from a business perspective. In these ecosystems,\r\nthird-party
developers upload extensions to a store which can be\r\ndownloaded by end users.
While the functional scope of such ecosystems\r\nis relatively similar, the underlying
business models differ greatly in and\r\nbetween their different product domains
(e.g. Mobile Phone, Smart TV).\r\nThis variability, in turn, makes it challenging
for store providers to \r\nfind a business model that fits their own needs.\r\nTo
handle this variability, we introduce the Business Variability Model\r\n(BVM)
for modeling business model decisions. The basis of these decisions\r\nis the
analysis of 60 store-oriented software ecosystems in eight\r\ndifferent product
domains. We map their business model decisions to the\r\nBusiness Model Canvas,
condense them to a variability model and discuss\r\nparticular variants and their
dependencies. Our work provides store\r\nproviders a new approach for modeling
business model decisions together\r\nwith insights of existing business models.
This, in turn, supports them\r\nin creating new and improving existing business
models."

text: "Models on network formation have often been extended to include the potential
of network disruption in recent years. Whereas the theoretical research on network
formation under the threat of disruption has thus gained prominence, hardly any
experimental research exists so far. In this paper, we therefore experimentally
study the emergence of networks including the aspect of a known external threat
by relating theoretical predictions by Dzuibiński and Goyal (2013) to actual observed
behaviour. We deal with the question if subjects in the role of a strategic Designer
are able to form safe networks for least costs while facing a strategic Adversary
who is going to attack their networks. Varying the costs for protecting nodes,
we designed and tested two treatments with different predictions for the equilibrium
network and investigated whether one of the least cost equilibrium networks was
more likely to be reached. Furthermore, the influence of the subjects’ farsightedness
on their decision-making process was elicited and analysed.\r\n\r\nWe find that
while subjects are able to build safe networks in both treatments, equilibrium
networks are only built in one of the two treatments. In the other treatment,
predominantly safe networks are built but they are not for least costs. Additionally,
we find that farsightedness –as measured in our experiment– has no influence on
whether subjects are able to build safe or least cost equilibrium networks. Two
robustness settings with a reduced external threat or more liberties to modify
the initial networks qualitatively confirm our results. Overall, in this experiment
observed behaviour is only partially in line with the theoretical predictions
by Dzuibiński and Goyal (2013)."

text: This thesis investigates approximate pure Nash equilibria in different game-theoretic
models. In such an outcome, no player can improve her objective by more than a
given factor through a deviation to another strategy. In the first part, we investigate
two variants of Congestion Games in which the existence of pure Nash equilibria
is guaranteed through a potential function argument. However, the computation
of such equilibria might be hard. We construct and analyze approximation algorithms
that enable the computation of states with low approximation factors in polynomial
time. To show their guarantees we use sub games among players, bound the potential
function values of arbitrary states and exploit a connection between Shapley and
proportional cost shares. Furthermore, we apply and analyze sampling techniques
for the computation of approximate Shapley values in different settings. In the
second part, we concentrate on the existence of approximate pure Nash equilibria
in games in which no pure Nash equilibria exist in general. In the model of Coevolving
Opinion Formation Games, we bound the approximation guarantees for natural states
nearly independent of the specific definition of the players' neighborhoods by
applying a concept of virtual costs. For the special case of only one influential
neighbor, we even show lower approximation factors for a natural strategy. Then,
we investigate a two-sided Facility Location Game among facilities and clients
on a line with an objective function consisting of distance and load. We show
tight bounds on the approximation factor for settings with three facilities and
infinitely many clients. For the general scenario with an arbitrary number of
facilities, we bound the approximation factor for two promising candidates, namely
facilities that are uniformly distributed and which are paired.

text: "The ongoing softwarization of networks creates a big need for automated testing
solutions to ensure service quality. This becomes even more important if agile
environments with short time to market and high demands, in terms of service performance
and availability, are considered.\r\nIn this paper, we introduce a novel testing
solution for virtualized, microservice-based network functions and services, which
we base on TTCN-3, a well known testing language defined by the European standards
institute (ETSI). We use TTCN-3 not only for functional testing but also answer
the question whether TTCN-3 can be used for performance profiling tasks as well.
Finally, we demonstrate the proposed concepts and solutions in a case study using
our open-source prototype to test and profile a chained network service."

text: In disaster operations management, a challenging task for rescue organizations
occurs when they have to assign and schedule their rescue units to emerging incidents
under time pressure in order to reduce the overall resulting harm. Of particular
importance in practical scenarios is the need to consider collaboration of rescue
units. This task has hardly been addressed in the literature. We contribute to
both modeling and solving this problem by (1) conceptualizing the situation as
a type of scheduling problem, (2) modeling it as a binary linear minimization
problem, (3) suggesting a branch-and-price algorithm, which can serve as both
an exact and heuristic solution procedure, and (4) conducting computational experiments
- including a sensitivity analysis of the effects of exogenous model parameters
on execution times and objective value improvements over a heuristic suggested
in the literature - for different practical disaster scenarios. The results of
our computational experiments show that most problem instances of practically
feasible size can be solved to optimality within ten minutes. Furthermore, even
when our algorithm is terminated once the first feasible solution has been found,
this solution is in almost all cases competitive to the optimal solution and substantially
better than the solution obtained by the best known algorithm from the literature.
This performance of our branch-and-price algorithm enables rescue organizations
to apply our procedure in practice, even when the time for decision making is
limited to a few minutes. By addressing a very general type of scheduling problem,
our approach applies to various scheduling situations.

text: We exploit a unique sample of structured financial products (SFPs) to analyze
pricing and issuance dependencies among different types of such market‐linked
investment vehicles. Our study provides evidence of cross‐pricing between products
with complementary payoff profiles. Such dependencies may be explained by issuers’
efforts to generate order flow for products that supplement their current SFP
risk exposure. Additionally, we observe issuance patterns in line with the argument
that issuers exploit the complementarity payout profiles when bringing SFPs to
market. Our study emphasizes cross‐pricing from a perspective not previously considered
in the literature.
