VHB-ProDok: Simulation Modeling for Business Research (10.-13.04.2017)

Abstract:
Business research increasingly considers wicked problems and complex dynamic systems. Analytical models of such problems and systems quickly become untraceable and unsolvable. Given increasing computational power, simulation models provide an alternative tool. They can fuel studies tracing the long-term evolution of systems and comparing the outcomes of alternative scenarios. However, successfully applying simulation modeling for business research requires expertise on applicable simulation paradigms, approaches to model validation and the analysis of stochastic results.

Abstract:
This doctoral seminar exposes students to foundational and current research in organization theory. It specifically focuses on macro-organizational theory, derived largely from sociological and economic theoretical traditions. This type of organizational theory is interested in the interaction of organizational structures and processes with the wider political, economic, societal, or natural environment. Among others, it tries to explain the emergence of organizational forms and organizational survival, resource acquisition and utilization, interaction between organizations, the perception of organizations in society, or organizational responsibility. Instead of giving a comprehensive historical introduction into the “classics” of organization theory, this course will focus on current advancements of core theoretical concepts such as sensemaking, institutions, routines or networks as well as on more recent theoretical streams such as the ‘strong’ process view of organization or the communicative constitution of organization. Assessment will mainly be based on reading assignments and participation.

Abstract:

The course covers the basic elements of i) Markovian models of stochastic systems and ii) Markovian decision processes plus some basic elements of inventory theory. In this course, participants will learn how to construct and use these particular classes of probabilistic models of systems and decision processes. The defining feature of the Markovian models is the memoryless property of the underlying stochastic processes. It essentially states that the future behavior of a system depends only on its current state, but not its previous history. The participants will learn why and how this often makes it possible to determine the probabilities of the different system states and how these probabilities can then be used to determine performance measures of the system or to assign economic values to decisions made in an uncertain environment.

Content

We will start by describing the defining features and variants of stochastic processes, focusing on those processes with a discrete state space. We will initially cover Markovian processes in discrete time as their modeling and analysis happens to be straightforward, clear and illustrative. On this basis, we will then address Markovian processes in continuous time, the so-called Markov Chains. We will describe Poisson processes, the famous memoryless property of the exponential distribution and derive the necessary and sufficient balance equations for the steady-state analysis of Markov Chains in continuous time. The participants will install and use Scilab, an free and open-source software for numerical computation (www.scilab.org), on their machines to perform numerical experiments and solve small exercises.

Based on this foundation, we will then address the analysis of Markovian queuing systems and show how to determine the probability of having a given number of customers or jobs in the system or the queue. After introducing and explaining Little’s Law, we will use it to determine expected waiting or cycle times. Closing this introduction to queuing models, we will briefly explain and demonstrate Kingman’s approximation for the expected waiting time G/G/1 and G/G/N queueing model.

In the next section, we will briefly cover basic elements of the probabilistic analysis of inventory systems. We will introduce the classical newsvendor problem and use it to explain and apply the first order loss function for the case of normally distributed demand.

The next part of the course will be devoted to stochastic (dynamic) programming, also known as stochastic decision processes. Starting with a finite-horizon deterministic setting, we will treat the basic version of Bellman’s recursion equation and explain its usage to determine an optimal course of actions in a multi-stage decision situation. On this foundation, we will next consider the stochastic case of a finite-horizon Markovian Decision Process in discrete time, explain the optimality equations and their solution via the backward induction algorithm. Finally, we will consider the infinite-horizon, continuous time case of discounted Markov decision processes and the value and policy iteration algorithms to determine policies that are optimal in expectation.

On the fourth day, we will consider a linkage between stochastic modeling and optimization by treating two-stage linear programs using scenario techniques. Here we will use the GAMS modeling system to essentially embed a numerical simulation within an (formally deterministic) linear or mixed-integer linear optimization program. We will furthermore discuss either (and preferably) current research projects of the participants that involve probabilistic modeling or (alternatively) some interesting papers showing the methodologies taught in the course.

Abstract:
The purpose of this course is to provide broad exposure to the research opportunities available using experimental data to explore management and financial accounting topics. Therefore, this course covers recent experimental studies from financial and managerial accounting areas that apply behavioral decision theory, psychology, and economics to address a variety of accounting research questions. This includes published research, as well as working papers, mainly from leading accounting researchers in the field.

The goals of this course are

  • to familiarize students with recent experimental research in accounting,
  • to help students develop the skills necessary to critically evaluate such research,
  • to help students find the right research method for their question and to challenge the limits of the experimental research method
  • to help students develop rigorous experimental designs for conducting their own research.

VHB ProDok: Design and Application of Modern Heuristics (October 10-13, 2016)

Abstract:
Modern heuristics like evolutionary algorithms, genetic programming, variable neighborhood search, tabu search, simulated annealing, and others are widely applied to large, difficult, or realistic optimization problems, for which efficient classical optimization methods are not available. Unfortunately, many text books teach such methods by providing detailed descriptions of the functionality of single examples of modern heuristics neglecting the underlying and common concepts. As a result, the design and application of modern heuristics is often not a systematic task but a result of repeated trial and error. Applicants apply textbook approaches and are wondering why they do not perform well when used for problems of realistic size or complexity.

This course takes a different approach. It teaches the basic, method-independent principles and design guidelines of modern heuristics and how they can be used to systematically develop superior heuristic optimization methods for problems of choice.
