Interdisciplinary Risk Estimation

The interdisciplinary risk estimation comprises two activities (1) risk assessment -producing the best estimate of the physical harm that a risk source may induce (including all scenarios that could compromise the safety of the facility under review) and (2) concern assessment — identifying and analyzing the issues that individuals or society as a whole link to a certain risk. For this purpose the repertoire of the social sciences, such as survey methods, focus groups, econometric analysis, macroeconomic modeling, or structured hearings with stakeholders may be used (Renn et al. 2011). 

Why are two types of assessments needed in risk governance For political and societal actors to arrive at reasonable decisions about risk and safely in the public interest, it is not enough to consider only the results of risk assessments, scientific or otherwise. In order to understand the concerns of affected people and various 

Interdisciplinary risk estimation consists of a systematic assessment not only of the risks to human health and the environment but also of related concerns as well as social and economic implications (cf IRGC 2005 Renn and Walker 2008). The interdisciplinary risk estimation process should be informed by scientific analyses yet, in contrast to traditional risk regulation models, the scientific process includes not only the natural sciences but also the social sciences, including economics. 

Extent of damage, or the adverse effects arising from an accident or the occurrence of a damaging event - measured in natural units such as deaths, injuries, production losses, and so forth. 

Probability of the event occurring and probability of the extent of damage induced by the event (relative frequency of a discrete or continuous loss function).

The measures designed to increase safety, and thus minimize risks within a material flow, are often influenced by the reliability of its individual components (transport machinery). Quantitative assessment of safety is carried out in the form of risk estimation or calculation the acceptable risk level is defined by the value of its acceptability for individual machines and machinery types. Using risk for the purpose of safety assessment of the material flow requires interdisciplinary procedures. It is crucial to correctly define a relationship between the probability of failure or a negative event occurrence and the consequence that the failure or negative event may cause. It is also essential to take into consideration various causes of negative events within the Man-Machine-Environment system as well as their consequences (location, time, person involved, duration of consequences, etc.). Appropriate statistical methods should be used for the purpose of risk (especially the probability of negative event occurrence) estimation or assessment.
