Abstract: | AbstractIn this paper, we look into how some qualitative types of risk assessments can be used in conjunction with functional resonance analysis method (FRAM) to strengthen the resilience of systems. In FRAM, variation in relation to meeting specified functions is central, but risk and uncertainty considerations are not an integral part. We suggest to add to FRAM an assessment of the modelling choices and judgements using strength of knowledge considerations and a qualitative sensitivity analysis. In this way, an improved basis for assessing and strengthening system resilience with FRAM is established. We illustrate the idea with a simple example from the oil and gas industry. |
