Fig. 2 Risk assessment framework augmentation proposed in Ref. [ 25 ]. The steps highlighted (1 1 , 1 2 , 1 5 , 2, 3 1 , 4 1 ) are the subject of augmentation (reinforcement actions 1 and 2). Those enable to (1)define the optimal level of analysis and (2) adequately characterize the problem. Preci... More about this image found in Risk assessment framework augmentation proposed in Ref.

Fig. 3 Simplified representation of the Three-Phases method logic [ 25 ]. A technological quality assessment enables to define the DMPK of a data source (i.e., how much of the required information can be provided by the data source for a specific parameter). Applying the two degradation factors (D... More about this image found in Simplified representation of the Three-Phases method logic [ 25 ]. A techno...

Fig. 4 Examples of analysis level options with respective detailing possibilities for an item of interest selected for a risk analysis. The levels of analysis 1, 2, and 3 represent three ways of isolating that item, for instance, on national, regional, and municipal level, respectively.

Fig. 5 Further decomposition possibilities of the item of interest isolated on the third level of analysis. This fine-graining gives the possibility to isolate up to 69 items in the sixth level, which can then individually be considered for a risk analysis. More about this image found in Further decomposition possibilities of the item of interest isolated on the...

Fig. 7 Decomposition of elements required in the estimation of the probability of outage due to a tree fall on a power line. This risk element is a function of three dimensions, themselves function of different parameters. The different data sources that can inform those parameters are also report...
