Example text

For example, both simplified and model-based risk analysis will be applicable for undersea tunnels. Initially, a simplified analysis can be undertaken to perform a crude risk analysis and to decide what the focus should be in a subsequent model-based risk analysis method. 2 Risk-based approach This section gives a brief description of the principles of a risk-based approach for the selection of a risk analysis method. The approach is based on Wiencke et al. (2006). The method was initially developed for the ICT industry, but can also be applied to other analysis subjects.

The analysis would typically be qualitative and its conclusions summarised in a matrix with performance shown by a simple categorisation system such as very positive, positive, neutral, negative, very negative. From this crude analysis a decision can be made to eliminate some alternatives and include new ones for further detailing and analysis. Frequently, such crude analyses give the necessary platform for choosing one appropriate alternative. When considering a set of possible risk-reducing measures, a qualitative analysis in many cases provides a sufficient basis for identifying which measures to implement, as these measures are in accordance with good engineering or with good operational practice.

Use of cost-benefit analysis is seen as a tool for obtaining efficient allocation of the resources, by identifying which potential actions are worth undertaking and in what way. e. if E[NPV] > 0. Although cost-benefit analysis was originally developed for the evaluation of public policy issues, the analysis is also used in other contexts, in particular for evaluating projects in firms. The same methods can be applied, but using values reflecting the decision-maker’s benefits and costs, and the decision-maker’s willingness to pay.
