1. A computer system comprising: a plurality of computer processor dependent nodes; a plurality of computer processor antecedent nodes; and relationships between the antecedent nodes and the dependent nodes; wherein the relationships comprise an aggregate relationship, a required relationship, a bound relationship, and a depends on relationship; wherein each node comprises a severity value relating to an operational state of the node; wherein a dependent node and an antecedent node pair comprise a significance value relating to a criticality that the antecedent node has to its paired dependent node; wherein the antecedent node comprises a relevance value, wherein the relevance value is a product of the severity value of the antecedent node multiplied by the significance value for the antecedent node and the dependent node; wherein the relevance value is used to determine an impact that the antecedent node has on the paired dependent node; wherein the impact the plurality of antecedent nodes has on their direct dependent node is determined by analyzing the relevance values for the plurality of antecedent nodes and their associated impact and a propagated relevance value associated with the dependent node; and wherein the analyzing comprises determining a first maximum between the relevance values for the plurality of antecedent nodes and their impact, and then determining a second maximum between the first maximum and a propagated relevance value associated with the dependent node.
