Abstract: Propagating data in a technical network by considering runtime requirements. A component tree data structure is generated for a probabilistic graph representing the technical network and its technical constraints. On the component tree a propagation algorithm is applied, which iteratively determines an optimal edge in the generated component tree, which maximizes an expected information flow to a query node to and/or from each network node by considering the technical network constraints and by executing a Monte-Carlo sampling for estimation of the expected information flow for the cyclic components and by computing the expected information flow of the non-cyclic components analytically and which updates the component tree iteratively with each determined optimal edge and re-estimates the expected information flow in the updated component tree for providing a result with nodes in the technical network for data propagation, so that information flow is maximized by considering technical network constraints.
