Three-dimensional numerical risk scoring

Three-dimensional numerical risk scoring systems... 

An extended three-dimensional numerical risk scoring system that includes a method to justify the risk amelioration costs in relation to the amount of risk... 

Similarly, some engineers are using numerical risk scoring systems to meet the risk assessment requirements placed on manufacturers who sell machinery to countries in the European Community. One such system in use for that purpose is four-dimensional. Also, a three-dimensional numerical risk-scoring system is in use in a segment of the heavy machinery manufacturing industry. It was introduced by engineering personnel to meet the demands for product safety. 

THREE-DIMENSIONAL NUMERICAL RISK-SCORING SYSTEMS... 

The goal was to create a three-dimensional numerical risk-scoring system that serves the needs of those who are more comfortable with statistics in their risk assessments, addresses the strong beliefs of those who want frequency of exposure given separate consideration in the risk assessment process, and maintains credibility and efficacy. An example demonstrating how the risk-scoring system is applied appears in Table 26. 

Three-dimensional numerical risk-scoring systems can be crafted that have credibility. But, how should such systems be used Numerical risk scores carry an image of precision that can influence decision making and priority setting. In reality, however, they should not be the sole or absolute determinant.
