Investigating Flexibility as a Performance Dimension of a Manufacturing Value Modeling Methodology (MVMM): A Framework for Identifying Flexibility Types in Manufacturing Systems
No full textIn recent years manufacturing companies have been faced with various challenges related to volatile demand and changing requirements from customer as well as suppliers. This trend is now even accelerating with a direct impact on the value chain. New technological roadmaps and suggested interventions in manufacturing systems try to solve these challenges and solutions such as the German high tech strategy "Industrie 4.0" or the Italian cluster "Fabbrica Intelligente" which often aimed at enhancing the flexibility of manufacturing systems among many other competitive dimensions. However, these approaches often do not provide a detailed definition of flexibility and its different manifestations. Therefore, the question rises if different types of flexibility, that have an impact on the complete manufacturing system, can be better identified with the existing Manufacturing Value Modeling Methodology (MVMM). This question becomes even more important when considering the potential that smart machines interacting with humans, such as cyber-physical systems (CPS), and the possibility to increase connectivity and data access through technologies, such as the internet of things (IoT), offer for increasing flexibility. Especially due to the various possibilities it becomes even more important to understand, which kind of flexibility is needed for a given problem. Implementing flexibility into the MVMM requires a 'catalog' that makes use of the MVMM framework presenting an overview of internal and external influence factors in order to support the identification of correct solutions and improvements related to functional areas in the manufacturing environment. Starting from a qualitative literature review on manufacturing flexibility, a 'flexibility catalog' is designed, which provides a structural definition of existing flexibility types and their composition as well as providing decision support. In conclusion, the scope of the 'flexibility catalog' is to verify that the flexibility demand fits into the market trends and is aligned to the manufacturing and company strategy, in order to help firms to take decisions and delivering value

Identifying Fashion Trendsetters in Online Social Networks by Advanced Analytics
Full text linkThe fashion industry operates in a highly competitive market with an increasing power of consumers regarding fashion trend creation and diffusion induced by the wide usage of online social networking platforms. This forces fashion companies to adapt their methods of trend prediction to meet consumer needs and preferences and to stay competitive. Social networking platforms provide an instrument to share ideas and opinions which allows users to influence others in their behaviors, and therefore, influence the development of trends. The content published on these platforms, thus, is a rich data source for the fashion industry containing information about changing consumer needs and upcoming trends. Fashion companies, however, challenge to benefit from this social media data for trend prediction purposes as they lack the knowledge about the trend-relevant users who publish content that includes information about future trends.
This research addresses the challenge of profiting from this valuable data source for trend prediction, especially in the highly competitive fashion industry. It argues that trends are created and diffused by trendsetters and that the content which is shared by these trendsetters in online social networks includes information that enables early trend detection. Due to this, the study seeks to identify trendsetters based on their digital trace which they leave on online social networking platforms and addresses the question of how fashion trendsetters in online social networks can be identified automatically based on social media data.
To achieve this goal, a feature framework is created based on literature review and expert interviews which enables the measurement of characteristics of trend-relevant roles based on social media data. Next, a two-step approach is developed which first extracts a topic-relevant sample of users (community) from a huge online social network, and then identifies the online trendsetters within this sample based on a supervised machine learning approach. For its development, a prototypical data analysis is realized based on publicly accessible data from the online social networking platform Instagram. The resulting methodology for the identification of online trendsetters related to a specific topic area consists of a topic-focused community detection approach and a classification model. The analysis of the relevant features for the model’s class decision further reveals insights into online trendsetters’ characteristics in online social networks. The evaluation of the developed methodology shows its transferability to other use cases and validates the trend prediction potential of the identified online trendsetters.
The results of this thesis contribute to research and practice. The insights gained about online trendsetters’ behavioral patterns, characteristics, and the relevant features for their detection in online social networks expand the knowledge about online trendsetters related to the fashion industry, and thus, contribute to the area of trend research and the recently emerging field of fashion informatics. Besides, the insights can be used by companies to identify appropriate marketing partners to influence trends. Furthermore, the developed methodology supports fashion companies with providing a new data source to increase trend prediction quality and facilitates the identification of changing consumer needs and preferences
Cultural Customization industrieller E-Services: Internationales Management industrieller E-Services unter besonderer Berücksichtigung kulturspezifischer Aspekte am Beispiel eines Unternehmens der Bauzulieferindustrie
No full textThe offer of customer-oriented solutions provides international industrial companies in the time of globalization the opportunity for differentiation and earnings. Industrial e-services as part of the industrial services therefor offer a starting point. In the beginning, the effectiveness of electronic services within the company are analyzed and the culture as an important starting point for differentiation is identified. This leads to a cultural customization approach in international management of electronic services, which is based on the transnational strategy of international companies. It shows an approach with a focus on innovative, strategic and operational e-service management. The development and provision of culturally customized e-services based on the principle of modularization of the mass customization approach and combines this with cultural aspects, which are both in the cultural dimensions of Hofstede, but also in the business processes of a country reflect. With the focus on cultural differences is a higher acceptance, usage and satisfaction with industrial e-services and thus a better differentiation from the competition prosecuted. The technological realization of the concept of cultural customization is done in a prototypically realized international process portal, which supports the whole process of e-service development and deployment from central and regional management to customer support. The process portal also offers the possibility of country-specific business processes and assigning e-services to tasks. The configuration of the e-services results in a culturally adapted offer for customers. A cultural feedback measures the use and evaluation of culturally customized e-services in different countries and is used for further improvement. A business case of a construction-company shows the ability of the cultural customization concept and its prototype realization in the countries Germany, Great Britain, Russia and China.Das Angebot ganzheitlicher, kundenorientierter Problemlösungen bietet internationalen Industrieunternehmen im Zuge der Globalisierung die Chance zur Differenzierung und Ergebnissteigerung. Industrielle E-Services als Teil der von Industrieunternehmen angebotenen Dienstleistungen bieten dazu einen Ansatzpunkt. In den Grundlagen werden die Erfolgswirksamkeit von elektronischen Dienstleistungen im Unternehmen analysiert und die Kultur als wichtiger Ansatzpunkt zur Differenzierung identifiziert. Dies führt zu einem Cultural Customization Konzept zum internationalen Management von elektronischen Dienstleistungen, welches sich an der transnationalen Strategie internationaler Unternehmen orientiert. Es zeigt ein Vorgehen mit den Schwerpunkten innovatives, strategisches und operatives E-Service-Management. Die Entwicklung und Bereitstellung der culturally customized E-Services beruht auf dem Prinzip der Modularisierung des Mass Customization-Ansatzes und verbindet dieses mit kulturellen Aspekten, die sich sowohl in den Kulturdimensionen von Hofstede als auch in den Geschäftsprozessen eines Landes widerspiegeln. Mit der Orientierung an den kulturellen Unterschieden wird eine höhere Akzeptanz, Nutzung und Zufriedenheit mit industriellen E-Services und dadurch eine bessere Differenzierung vom Wettbewerb verfolgt. Die technologische Umsetzung des Konzeptes der Cultural Customization erfolgt in einem prototypisch realisierten internationalen Prozessportal, das den gesamten Prozess der E-Service-Entwicklung und -Bereitstellung auf den Ebenen des zentralen und regionalen Managements bis hin zum Kunden unterstützt. Das Prozessportal bietet darüber hinaus die Möglichkeit, landesspezifische Geschäftsprozesse abzubilden und eine Zuordnung von E-Services zu Aufgaben im Geschäftsprozess vorzunehmen. Die Konfiguration der E-Services führt zu einem kulturell angepassten Angebot für Kunden. Durch ein kulturelles Feedback wird die Nutzung und Bewertung der culturally customized E-Services in den verschiedenen Ländern gemessen und zur weiteren Verbesserung des E-Service-Angebotes verwendet. Ein Business Case am Beispiel eines Unternehmens der Bauzulieferindustrie zeigt die Einsatzfähigkeit des Cultural Customization Konzeptes und dessen prototypische Realisierung in den Ländern Deutschland, Großbritannien, Russland und China
