Reproducibility investigation of elicitation techniques in risk assessment for hydraulic turbines

Abstract

Certain elicitation techniques exert some control on expert opinions by leading them to a consensus or to a specific choice. In the absence of such guidelines, experts rely on their own knowledge to formulate opinions. This can result in large dispersions and affects the decision maker’s judgment. In this situation, we wonder what the relevant elicitation techniques are and how we can help experts to express their knowledge. From literature review, it is hard to decide if elicitation techniques are equivalent or not, which justifies the reproducibility analysis that we carry out in this paper. In this study, multiple experts have been involved in order to predict the defect size in hydraulic turbines, according to four proposed elicitation techniques. The comparison between these techniques was performed based on a suggested algorithm using the area metric concept. Our Findings show that elicitation techniques with ‘support’ tend to limit variations between experts and might be suitable only when prior knowledge on the expected elicited variable is available. Otherwise, we can end up with a distorted opinion of the elicited variable and an erroneous risk assessment.

Futures beyond dystopia

The speculative imagination is an higher-order human capacity that can productively explore the not-here and the not-yet. To some extent it is already doing so. But these explorations are limited by prevailing cultural assumptions. The purpose of this paper is to suggest that there are other arenas to explore that, were they taken seriously, could exert sufficient symbolic ‘pull' to qualify as desirable images of futures. They could then begin to act as ‘magnets' for the realisation of possibilities that are presently obscured.
