Abstract: Scenario representation manipulation methods, scenario analysis devices, articles of manufacture, and data signals are described according to some aspects. In one aspect, a scenario representation manipulation method includes accessing a graphical representation comprising a plurality of nodes and a plurality of associations of the nodes, wherein the nodes and the associations of the nodes are indicative of a scenario, providing a plurality of defined structural arrangements, wherein the defined structural arrangements comprise a plurality of nodes and associations of the nodes, analyzing the nodes and associations of the nodes of the graphical representation using the defined structural arrangements, and generating another representation of the graphical representation responsive to the analyzing.

Abstract: Scenario analysis methods, scenario analysis devices, articles of manufacture, and data signals are described according to some aspects. In one aspect, a scenario analysis method includes accessing a representation of a first scenario, accessing a plurality of representations of a plurality of second scenarios, analyzing the representation of the first scenario with respect to the representations of the second scenarios, determining a plurality of relationships of the representation of the first scenario with respect to respective ones of the representations of the second scenarios responsive to the analyzing, and ranking the relationships.
