Patent ID: 7627601

Claim:
A computer-implemented method for performing an analysis of the impact of a variable on a plurality of simulation models, said method including: acquiring, by a computer and from a database, performance data relating to said variable within a timeframe parameter and a presentation parameter, wherein said performance data includes dependency data and a variable score; analyzing, by said computer, said dependency data relating to said variable to determine a subset of said plurality of simulation models impacted by said dependency data, wherein said dependency data relates to a transfer of information exchanged between said variable and said subset of said plurality of simulation models, wherein said information includes at least one of accuracy of said information, an amount of said information, a transfer rate of said information, or a processing rate of said information; determining, by said computer, an impact of said variable on said subset of said plurality of simulation models, by analyzing said dependency data; creating, by said computer, a visualization showing a plurality of variable names, wherein said plurality of variable names are arranged according to said dependency data, and wherein said dependency data corresponds to functional dependencies between said plurality of simulation models and said variable; modifying, by said computer, a variable score based on said impact to create a modified variable score; and, at least one of: modifying said variable or decommissioning said variable within said database based on said modified variable score.
