Computer-implemented decision management systems and methods are provided. The method comprises obtaining information associated with factors usable for making a decision from among a plurality of inter-related decisions represented by a plurality of corresponding nodes. The computing environment provides access to resources that store information about relationships among the plurality of nodes. A relationship may be presentable as an edge connecting at least two nodes from among the plurality of nodes. The strength of the relationship between the at least two nodes is measurable and definable based on associations between the inter-related decisions. A valued may be determined that provides a measure for the strength of the relationship between the at least two nodes based on the information associated with the factors and the information about the relationships among the plurality of nodes.
