Abstract in another language

Global supply networks that can be considered as interlaced supply chains are shaping existing economic structures. These supply networks are creating a high level of complexity. Simultaneously, the perceived number of exogenous shocks such as natural disasters is increasing. These exogenous shocks can directly or indirectly impact the participating companies of a supply network, which can also threaten the network as a whole. However, the complexity and opacity of today’s supply networks inhibits an accurate prediction and quantification of such impacts. Therefore, companies are unable to develop adequate safeguards, while existing mechanisms are insufficient. The objective of this study is to model, analyze, and quantify the impacts of exogenous shocks on supply networks. Therefore, we use a Petri Net-based approach, which enables a simulation of different supply network constellations, to assess the vulnerability to exogenous shocks. Furthermore, we include a detailed description of modeling and evaluation of the presented method. For an exemplary supply network, we simulate different intensities of an exogenous shock combined with different safety stocks of the entities. Statistical tests are conducted to verify the results. We thereby illustrate the results that could be yielded from a real-world application.
