  • Assessing IT availability risks in smart factory networks

    • Authors: Ha ¨ ckel, Bjo ¨ rn;  Advisor: -;  Participants: Ha ¨ nsch, Florian; Hertel, Michael; U ¨ belho ¨ r, Jochen (2019)

  • Emerging smart manufacturing technologies combine physical production networks with digital IT systems, resulting in complex smart factory networks, which are especially vulnerable to IT security risks, such as IT component nonavailabilities. Companies must employ extensive IT security measures to secure their production facilities. However, complex network structures and inherent dependencies of smart factory networks complicate corresponding investment decisions and increase the need for appropriate decision support. We develop a risk assessment model that supports companies in the investment decision-making process regarding IT security measures by identifying and evaluating the m...

  • Evaluating investments in flexible on-demand production capacity: A real options approach

    • Authors: Freitag, Bettina;  Advisor: -;  Participants: Ha ¨ fner, Lukas; Pfeuffer, Verena; U ¨ belho ¨ r, Jochen (2019)

  • Ongoing digitalization of production accelerates trends like mass customization, ever shorter lead times, and shrinking product life cycles. Thereby, industrial companies face increasingly volatile demand that complicates an appropriate production capacity planning. On the other hand, the comprehensive digitalization of production environments favors, amongst others, the dynamic integration of flexible external on-demand production capacity provided by specialized external capacity providers (ECPs). To enable the usage of on-demand production capacity, industrial companies may require significant upfront investments (e.g., for inter-organizational information systems, planning and orga...
