<p>A method of assessment of a risk (R) involved in operating a measurement device on a measurement site in an industrial process is described, which takes into account a maintainability (M) of the device, comprising the steps of: determining a degree of difficulty of a maintainability (M) of the device, determining a probability (P) of an undetected defect of the device, determining a severity (S) of the consequences of the defect of the device, weighing the determined probability (P), the determined severity (S) and the determined degree of difficulty of the maintainability (M) with corresponding predefined weighing factors (g s , g p , g M ) corresponding to a contribution of the difficulty of maintainability (M), the probability (P) and the severity (S) to the risk (R), and determining the risk (R) based on a length (L R ) of a vector ( V ) whose coordinates are given by the weighted degree of difficulty of the maintainability (g M M), the weighted probability (g p P) and the weighted severity (g s S).</p> |
