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; and wherein the relevance value is used to determine an impact that the antecedent node has on the paired dependent node.
