- TextdokumentAdapting Binary Decision Diagrams for Visualizing Product Configuration Data(INFORMATIK 2017, 2017) Bischoff, Daniel; Küchlin, WolfgangThis paper deals with the challenges of visualizing and understanding complex interacting Boolean formulæ for selecting parts in an automotive Bill-of-Materials (BoM). Our approach targets entire BoM positions containing all variants of a part, each with its own selection formula. A part variant is needed for a car if the selection formula evaluates to true under the option list (feature list) which defines the car variant. Understanding the formulæ is critical when editing or when trying to analyze and explain a bug, but it is non-trivial. SAT-solving is commonly used to detect bugs, but explaining the cause of bugs is a different matter. Our approach is to visualize all selection alternatives in a single diagram based on an adaptation of binary decision diagrams (BDDs). We also visualize the influence of the configuration constraints for car variants on the selection diagrams and show how they can help to reduce their size. Based on this method we implemented a visualization tool which additionally serves as a visual formula editor.
- TextdokumentSmart Meter based Business Models for the Electricity Sector - A Systematical Literature Research(Digital Enterprise Computing (DEC 2017), 2017) Bischoff, Daniel; Kinitzki, Martin; Wilke, Tim; Zeqiraj, Flamur; Zivkovic, Sanja; Koppenhöfer, Christine; Fauser, Jan; Hertweck, DieterThe Act on the Digitization of the Energy Transition forces German industries and households to introduce smart meters in order to save energy, to gain individual based electricity tariffs and to digitize the energy data flow. Smart meter can be regarded as the advancement of the traditional meter. Utilizing this new technology enables a wide range of innovative business models that provide additional value for the electricity suppliers as well as for their customers. In this study, we followed a two-step approach. At first, we provide a state-of-the-art comparison of these business models found in the literature and identify structural differences in the way they add value to the offered products and services. Secondly, the business models are grouped into categories with respect to customer segments and the added value to the smart grid. Findings indicate that most business models focus on the end-consumer as their main customer.
