Abstract
A method for dependent task prioritization is disclosed. The method comprises providing base data comprising task identifiers, failure values and dependency data values, where each dependency data value is associated with a pair of tasks. The method comprises also generating a probabilistic model, using a directed acyclic graph, where each task is associated with a network node, and where each dependency data value is associated with a network edge of the directed acyclic graph, wherein each dependency data value is indicative of a conditional probability in relation to the respective failure rate per time unit. Additionally, the method comprises determining for each task in the acyclic directed graph a posterior marginal probability value indicative of a probability of a failure of the task, and selecting, based upon the posterior marginal probability values, a sequence of tasks that is likely to fail fastest.
