<p>There is disclosed a method for assessing and managing risk within a process comprising: (i) receiving data relating to a probability (P) of two or more mishaps occurring within said process, and data relating to a severity (S) of two or more mishaps occurring within the process; (ii) defining a range of probability (P) values and severity (S) values as the span from the minimum to maximum values received; (iii) defining a range of risk (R) as the products of the minimum and maximum (P) and (S) values; (iv) obtaining logarithmic values of probability (P), severity (S), and risk (R) and scaling the ranges of the logarithmic values such that (P), (S), and (R) values are represented as percentages (0-100%); (v) determining a percentage of any values of P and S specified at intermediate stations within their respective ranges; (vi) computing a percentage, rank and value of risk (R) for any intermediate combination of probability (P) and severity (S) values specified; and, (vii) comparing the computed risk results against acceptable and unacceptable criteria to determine whether the risk is tolerable, and hence to be managed with suitable control scenarios.</p> |
