Computer simulation has evolved to a standard means for planning, analyzing, and optimizing complex systems. Yet, a twofold usage can be observed: as a tool for generating data and as a method for deriving knowledge. The objective of this paper is to outline epistemological consequences arising from this methodological uncertainty by analyzing the state of(More)
Technological innovation and requirements of modern production are leading to a significant transformation of logistics. Cyber-physical systems are introduced as an integrating concept for improving information flow from execution to decision systems and vice versa. Accompanied by decision and information systems with an increasing degree of autonomy, new(More)
Stress-related cortisol secretion has been linked to increased appetite and subsequent food intake in overweight individuals. The present study addresses this relationship in a repeated-measures randomized controlled laboratory experiment. Nineteen obese women were compared to 36 normal weight controls with respect to stress-induced salivary cortisol and(More)
The aim of computer simulation studies is to answer research questions by means of experiments. For providing reliable evidence, the procedure of the study needs to be aligned with the question and the steps of the study need to be adjusted and combined accordingly. Supporting this process is challenging as the identification, customization, and combination(More)
Social networks have evolved to a key technology for information diffusion. Consequently, discourse behavior and communication dynamics have become an important research area. However, privacy settings limit data acquisition extremely, such that empirical online content and discourse analysis are hardly applicable here. Since the “human factor” mostly(More)
