Global Value Trees
The fragmentation of production across countries has become an important feature of the globalization in recent decades and is often conceptualized by the term "global value chains" (GVCs). When empirically investigating the GVCs, previous studies are mainly interested in knowing how global the GVCs are rather than how the GVCs look like. From a complex networks perspective, we use the World In...
متن کاملUsing Intervals for Global Sensitivity Analyses in Multiattribute Value Trees
Sensitivity analyses have been long used to assess the impacts of uncertainties on the outcomes. Several approaches have been suggested, but it has been problematic to get a quick overview of the total impact of the uncertainties. Here it is suggested that interval analyses could be used for global sensitivity analyses and a nuclear emergency case is used to illustrate the method. With interval...

متن کاملUsing intervals for global sensitivity and worst-case analyses in multiattribute value trees
Sensitivity analyses have for long been used to assess the impacts of uncertainties on outcomes of decision models. Several approaches have been suggested, but it has been problematic to get a quick overview of the total impact of the uncertainties. Here we show how interval modeling can be used for global sensitivity analyses and a nuclear emergency case is used to illustrate the method. The a...
متن کاملGlobal Numerical Constraints on Trees
We introduce a logical foundation to reason on tree structures with constraints on the number of node occurrences. Related formalisms are limited to express occurrence constraints on particular tree regions, as for instance the children of a given node. By contrast, the logic introduced in the present work can concisely express numerical bounds on any region, descendants or ancestors for instan...
