Patent ID: 7930230

Claim:
A computer-implemented method for risk evaluation comprising: assigning a plurality of risks to a first object, wherein the first object comprises: an object estimation-value that represents an estimate of a first target value, a risk estimation-value that represents an estimate of impact of at least one of the plurality of risks to the first target value, a risk status for the first target value, and a unit of measure that numerically represents the object estimation-value and the risk estimation-value; assigning one of the plurality of risks to a second object, wherein the second object comprises a risk status for a second target value; re-calculating, by a computer system comprising a processor, the object estimation-value by using the risk estimation-value, wherein the re-calculating comprises applying a mathematical operation to the object estimation-value and the risk estimation-value; and calculating the risk status for the first target value by comparing total impact of the plurality of risks with a predefined threshold value and using the risk status for the second target value.
