skos:definition "Often used interchangeably with 'assessment', especially in more specific terms <br/>such as ‘'safety' 'analysis'’. In general, however, 'analysis' suggests the 'process' and <br/>result of a study aimed at understanding the subject of the 'analysis', while <br/>'assessment' may also include determinations or judgements of acceptability. <br/>'Analysis' is also often associated with the use of a specific technique. Hence, <br/>one or more forms of 'analysis' may be used in 'assessment'.<br/>
<i><b>cost–benefit analysis.</b></i> A systematic economic evaluation of the positive <br/>effects (benefits) and negative effects (disbenefits, including monetary <br/>costs) of undertaking an action.<br/>
A decision aiding technique commonly used in the 'optimization' <i>of protection <br/>and safety</i>. This and other techniques are discussed in Ref. [8].<br/>
<i><b>event tree analysis.</b></i> An inductive technique that starts by hypothesizing <br/>the occurrence of basic 'initiating events' and proceeds through their logical <br/>propagation to 'system failure' 'events'.<br/>
The 'event' tree is the diagrammatic illustration of alternative outcomes of <br/>specified 'initiating events'.<br/>'Fault tree analysis' considers similar chains of 'events', but starts at the other end <br/>(i.e. with the ‘results’ rather than the ‘causes’). The completed 'event' trees and <br/>fault trees for a given set of 'events' would be similar to one another.<br/>
<i><b>fault tree analysis.</b></i> A deductive technique that starts by hypothesizing <br/>and defining 'failure' 'events' and systematically deduces the 'events' or <br/>combinations of 'events 'that caused the 'failure' 'events' to occur.<br/>
The fault tree is the diagrammatic illustration of the 'events'.<br/>'Event tree analysis' considers similar chains of 'events', but starts at the other <br/>end (i.e. with the ‘causes’ rather than the ‘results’). The completed 'event' trees <br/>and fault trees for a given set of 'events' would be similar to one another.<br/>
<i><b>safety analysis.</b></i> Evaluation of the potential hazards associated with the <br/>conduct of an 'activity'.<br/>
'Safety analysis' is often used interchangeably with 'safety assessment'. However, <br/>when the distinction is important, 'safety analysis' should be used for the study <br/>of 'safety', and 'safety assessment' for the evaluation of 'safety' — for example, <br/>evaluation of the magnitude of hazards, evaluation of the performance of <br/>'safety measures' and judgement of their adequacy, or quantification of the <br/>overall radiological impact or 'safety' of a 'facility 'or 'activity'.' '<br/>
<i><b>sensitivity analysis.</b></i> A quantitative examination of how the behaviour of <br/>a 'system' varies with change, usually in the values of the governing <br/>parameters.<br/>
A common approach is parameter variation, in which the variation of results <br/>is investigated for changes in the value of one or more input parameters <br/>within a reasonable range around selected reference or mean values, and <br/>perturbation 'analysis', in which the variations of results with respect to <br/>changes in the values of all the input parameters are obtained by applying <br/>differential or integral 'analysis'.<br/>
<i><b>uncertainty analysis.</b></i> An 'analysis' to estimate the uncertainties and error <br/>bounds of the quantities involved in, and the results from, the solution of <br/>a problem.<br/>" (en)
