Patent ID: 7590594

Claim:
A method implementing by a programmed computer system for ranking relative risk of a plurality of transactions, wherein each of the transactions has associated therewith a plurality of variables, comprising: assigning a value to each of the variables associated with each of the transactions, with the computer system; aggregating the values assigned to each of the variables on a transaction by transaction basis to produce an aggregate risk level for each transaction, with the computer system; and ranking each of the transactions relative to one another based upon the aggregate risk level corresponding to each transaction with the computer system displaying at least one transaction based on the ranking of the transactions relative to one another based upon the aggregate risk level corresponding to each transaction; wherein the step of assigning a value to each of the variables associated with each of the transactions further comprises assigning a normalized risk factor value to each of the variables associated with each of the transactions based upon a raw value associated with each of the variables of each of the transactions and wherein the step of aggregating the values assigned to each of the variables on a transaction by transaction basis to produce an aggregate risk level for each transaction further comprises aggregating the normalized risk factor values assigned to each of the variables on a transaction by transaction basis to produce an aggregate risk level for each transaction; wherein each value is normalized to a predetermined normalization range; wherein the predetermined normalization range is between 0 to 1, inclusive; and wherein each variable has associated therewith an operational tolerance and the normalized risk factor value for each variable is calculated using the formula: RF =ξ●( e x/β −1) where RF=the normalized risk factor value, ξ=0.5819767069, e=2.718182818, x=the raw value of the variable, and β=the operational tolerance of the variable.
