Praxisbuch für Entscheider des produzierenden Gewerbes745-778Methoden zur Ableitung von Energiestrategien in komplexen Entscheidungssituationen20160_SW_noRef happach tilebein Mit Beginn des Liberalisierungsprozesses des europäischen Gas‐ und Elektrizitätsmarktes in den 1990er‐Jahren und der damit einhergehenden Umgestaltung der wirtschaftlichen und rechtlichen Rahmenbedingungen kam es zu tiefgreifenden Änderungen für energieintensive Industrieunternehmen. Diese Änderungen umfassen nicht nur Unbundling, Auktionen und neuen Wettbewerb in der Energiewirtschaft, sondern schließen außerdem den Wandel zu erneuerbaren Energien und ein unternehmerisches Umdenken bei der Energiebeschaffung mit ein. Das Ziel der Bundesregierung, bis 2050 den Anteil von erneuerbaren Energien am Energiemix auf 80 Prozent zu steigern, macht Investitionen erforderlich und stellt energieintensive Unternehmen vor Entscheidungen, beispielsweise ob sie Investitionen zur Energieproduktion tätigen oder neue Energiezulieferer finden.
Die beschriebenen fundamentalen Änderungen der Rahmenbedingungen ergeben für die betroffenen Unternehmen eine dynamisch‐komplexe Entscheidungssituation, aus der jedoch keine allgemein gültigen eindeutigen Handlungsempfehlungen abzuleiten sind. Diese sind daher stets unternehmensindividuell zu erarbeiten. Der vorliegende Beitrag zeigt dazu verschiedene Methoden auf, mit denen komplexe Entscheidungstatbestände detailliert untersucht und analysiert werden können. Dabei werden die folgenden Methoden beschrieben und an einschlägigen Beispielen demonstriert: Modellierung des Wertschöpfungsnetzwerks, Kausaldiagramme, System‐Dynamics‐Simulationsmodelle und agentenbasierte Modellierung. Ziel dieses Beitrags ist es, anwendungsorientierte Methoden der Entscheidungsunterstützung zu präsentieren, die dabei helfen können, dynamisch‐komplexe Situationen besser zu analysieren und unternehmensindividuell passende Strategien dafür zu erarbeiten.Bathtub Dynamics Revisited: Disclosing Traces of Déformation Professionelle in Higher Educationhttps://puma.ub.uni-stuttgart.de/bibtex/254784d2401e234265806d89722188fad/idsids2019-09-26T13:23:08+02:000_inKonferenzband happach kapmeier tilebein <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="F Kapmeier" itemprop="url" href="/person/1ad7e287949e0fcf24eea2645b61fb1f9/author/0"><span itemprop="name">F.

Some researchers claim, however, find indications that simple mechanisms like stocks and flows are not well understood even by people who have passed higher education. In this paper, we test people’s understanding of complex systems with the widely studied stock-and-flow (SF) tasks (Booth Sweeney and Sterman 2000). SF tasks assess people’s understanding of the interplay between stocks and flows. We investigate SF failure of domain experts and novices in different knowledge domains. In particular, we compare performance on the original study’s Bathtub task with the square wave pattern (Booth Sweeney and Sterman 2000) with two alternative cover stories from the engineering and business domains on different groups of business and engineering students from different semesters. Further, we show that, while engineering students perform better than business students, with progressing in higher education, students seem to lose the capability of dealing with simple SF tasks from domains other than their field. We thus find hints on déformation professionelle in higher education.Bathtub Dynamics Revisited: Does Education Background Matter?https://puma.ub.uni-stuttgart.de/bibtex/22b9c93b2d2b3148182eab3732f7047eb/idsids2019-09-23T15:31:40+02:000_Konferenzbeitrag happach kapmeier tilebein <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="F Kapmeier" itemprop="url" href="/person/1d3a3421c26a86da88f26e54c83f40f64/author/0"><span itemprop="name">F.

While results indicate that, among other things, domain specific experience and familiarity with the problem context play a role in this stock-flow-(SF-)performance, this has not yet been fully clarified. In this article, we present an experiment that examines the role of educational background in SF-performance. We hypothesize that SF-performance increases when the problem context is embedded in the problem solver’s knowledge domain, indicated by educational background. Using the square wave pattern and the sawtooth pattern tasks from the initial study by Booth Sweeney and Sterman (2000), we design two additional cover stories for the former, the Vehicle story from the engineering domain and the Application story from the business domain, next to the original Bathtub story. We then test the three sets of questions on business students. Results mainly support our hypothesis. Interestingly, participants even do better on a more complex behavioral pattern from their knowledge domain than on a simpler pattern from more distant domains. Although these findings have to be confirmed by further studies, they contribute both to the methodology of future surveys and the context familiarity discussion.

A Case of Policy Resistance.20130_inKonferenzband happach tilebein In 2003, the German government introduced a deposit on disposable single-use beverage containers in
addition to the already existing deposit on reusable beverage containers. Politicians meant to enhance and stabilize
the use of reusable beverage containers by lowering the attractiveness of beverages in single-use containers through
a high deposit. After the new law was introduced, the usage of reusable beverage containers increased, but after a
while it started to decrease again. The aim of this paper is to analyze the assumed feedback mechanisms behind this
unexpected behavior. Our analysis shows, that the establishment of the container deposit in Germany is a prime
example of policy resistance, which is a common problem in policy making. We argue that the unexpected behavior
can be explained by the fact that unclaimed deposit counts as profit for retail and production companies. In that way,
the container deposit made beverages in single-use containers less attractive for the consumers but, in turn,
increased the profit per unit for the retailers. That led to a higher supply of beverages in single-use containers and a
massive shortfall of beverages in reusable containers. Consumers substituted their demand by available beverages in
single-use containers and that results in higher sales for the retailers. The sales, in turn, are an incentive to provide
an even higher supply of beverages in single-use containers as it otherwise would have been.Ein Modell zur Einführung des Einwegpfands in Deutschlandhttps://puma.ub.uni-stuttgart.de/bibtex/2e3a50c54022e567e3e07c97e44a43023/idsids2019-09-23T15:31:39+02:000_inKonferenzband happach tilebein <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="R.

Reasons for SF-failure can be attributed to different reasons, one of them being lacking domain specific experience, thus familiarity with the problem context. In this article we present a continuation of an experiment to examine the role of educational background in SFperformance. We base the question set on the Bathtub Dynamics tasks introduced by Booth Sweeney and Sterman (2000) and vary the cover stories. In this paper we describe how we developed and tested a new cover story for the engineering domain and implemented the recommendations from a prior study. We test three sets of questions with engineering students which enables us to compare the results to a previous study in which we tested the questions with business students. Results mainly support our hypothesis that context familiarity increases SF-performance. With our findings we further develop the methodology of the research on SF-failure.

Those interactions are composed of multiple simultaneous, dynamically evolving processes with several different agents. However, researchers in the field of management science traditionally focus on aggregated characteristics and assume equilibria, thus correctly neglecting the level of individual agents. Thus, most research methods in management science are based on cross-sectional data as well as stable and predictable events.
Recently, modeling and simulation methods are becoming increasingly accepted among management scientists in order to better cope with complex problems and to better capture the underlying processes of social interactions.
In this paper, we present simulation as an appropriate research method to better handle complexity within this field. In particular, we present two distinct simulation methods: Agent-based modeling and system dynamics. We discuss the value and use of simulation models for supporting theory building and testing in management science. Further, we discuss the prerequisits, advantages and challenges of simulation methods.
Aside of general advantages that any simulation method offers, we also point to differences between the two simulation methods. In summary, we advocate a stronger use of simulation as additional research method in management science because it may improve the reliability and soundness of existing theories by focusing on the social interactions which are drivers of most business processes. At the same time, we emphasize the need for in-depth methodological knowledge and a thorough understanding of adequacy of the simulation method for the problem under investigation.Bathtub Dynamics Revisited: An Examination of Déformation Professionelle in Higher Educationhttps://puma.ub.uni-stuttgart.de/bibtex/2f5131b19dd80e8cb584b4ff5b4169341/idsids2019-05-23T11:51:40+02:000_Journal happach kapmeier tilebein <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="F Kapmeier" itemprop="url" href="/person/11e96e7f32ca1dd78a18568630b32ef8d/author/0"><span itemprop="name">F.
