Dynamic Pricing in Different Industries

Dynamic pricing describes a pricing strategy to set up highly flexible prices for products and services. Dynamic pricing algorithms adjust prices easily and frequently based on collected consumer data and market information. Dynamic pricing is used in various industries and has the potential to magnify revenues while offering multiple other benefits for companies. This paper analyzes the relevance and importance of dynamic pricing in sports, entertainment, leisure-time activities, hospitalities, and public transportation. For every industry, selected applications, and examples are analyzed. Finally, this paper investigates if dynamic pricing is fair and how customers respond to frequent price changes

Trends & Challenges in the Food Supply Chain

The food supply chain (FSC) comprises food production, storage, delivery, and retailing of food to reach the final customers by the due date. In general, the modern FSC is extraordinarily complex and challenging to manage; therefore, an efficient and effective supply chain requires appropriate management. All actors in the FSC have to keep track of the most recent trends and challenges and respond to changes quickly to keep up production and stay competitive. This paper explains some selected trends and challenges in the modern FSC. Moreover, the influence of the ongoing COVID-19 pandemic and the impact of the Ukraine war on the FSC are investigated. Despite the new trends and massive improvements in the FSC in terms of efficiency, some current problems remain unsolved, whereas new issues will arise in the future. The COVID-19 outbreak and the Ukraine war are two examples that imposed new challenges and significant consequences on the FSC

Maximizing Retail Potential: The Role of Big Data Analytics

The retail industry has been transformed by technological advancements and evolving consumer behavior. This paper examines the benefits, challenges, and strategic implications of Big Data Analytics (BDA) in the retail sector through a comprehensive review of recent literature. The findings highlight three key opportunities for leveraging BDA in retail: enhancing customer relationships, improving operational efficiency, and gaining strategic advantages. However, several challenges persist, including privacy and security concerns, inadequate data-driven support systems, complexities in data visualization and processing, and insufficient governmental support. In addition to exploring the potential advantages and limitations, this study emphasizes the strategic role of BDA in facilitating data-driven decision-making for retailers. By balancing these opportunities and challenges, retail firms can harness Big Data as a critical source of competitive advantage. Finally, the paper identifies future research directions to further advance the application of Big Data in the retail sector, aiming to address existing gaps and unlock its full potential

Forschungsarbeiten des Instituts für Werkstoffe der Technischen Universität Braunschweig

Das Institut für Werkstoffe ist aus einer Reihe von Zusammenlegungen und Aufteilungen innerhalb der letzten 50 Jahre hervorgegangen. Aus dem um 1930 bestehenden Laboratorium für Festigkeitsuntersuchungen mit Wöhler-Institut und dem Technologischen Institut für Schweißtechnik ist es schließlich durch Ausgliederung der Schweißtechnik entstanden. Es wird von einem Vorstand, bestehend aus Herrn Prof. Günter Lange und dem Verfasser, geleitet. Das Institut für Werkstoffe ist eine vorwiegend experimentell arbeitende wissenschaftliche Einrichtung mit einem großen Gerätepark. Es ist zuständig für die Grundausbildung aller Studenten in Werkstoffkunde für die Fachbereiche "Maschinenbau" und "Elektrotechnik". Dem Institut ist eine amtlich anerkannte Materialprüfstelle für Werkstoffe des Maschinenbaus angegliedert. Die Schwerpunkte der gegenwärtigen Forschungsaktivitäten liegen auf den Gebieten des mechanischen und des thermischen Verhaltens von metallischen Werkstoffen. Das Interesse erstreckt sich dabei sowohl auf "klassische" Werkstoffe, wie beispielsweise Aluminium- oder Kupferlegierungen oder Stähle, als auch auf "moderne" Werkstoffe, von denen amorphe Legierungen, sogenannte metallische Gläser, oder nanokristalline Materialien beispielhaft genannt seien. Im einzelnen lassen sich die Aktivitäten fünf Arbeitsgebieten zuordnen

Microstructural and mechanical characterization of annealed tungsten (W) and potassium-doped tungsten foils

Here we show that potassium-doped tungsten foil should be preferred to pure tungsten foil when considering tungsten laminate pipes for structural divertor applications. Potassium-doped tungsten materials are well known from the bulb industry and show an enhanced creep and recrystallization behaviour that can be explained by the formation of potassium-filled bubbles that are surrounding the elongated grains, leading to an interlocking of the microstructure. In this way, the ultra-fine grained (UFG) microstructure of tungsten foil can be stabilized and with it the extraordinary mechanical properties of the foil in terms of ductility, toughness, brittle-to-ductile transition, and radiation resistance. In this paper we show the results of three-point bending tests performed at room temperature on annealed pure tungsten and potassium-doped tungsten foils (800, 900, 1000, 1100, 1200, 1300, 1400, 1600, 1800, 2000, 2200, and 2400 °C for 1 h in vacuum). The microstructural assessment covers the measurement of the hardness and analyses of fractured surfaces as well as a comparison of the microstructure by optical microscopy. The results show that there is a positive effect of potassium-doped tungsten foils compared to pure tungsten foil and demonstrate the potential of the doped foi
