Scalable structuration challenges

This RQ aims at adaptation of ER approach to a goal structured safety case. We need to identify ways in which the confidence can be quantified in the argument patterns proposed [5]. We also need to identify ways in which the assurance deficit is captured and communicated to the assessor. As a potential challenge, we need to account for the fact that the confidence arguments are not necessarily tree-structured. We need to identify an approach that enables feeding the answers to the questions (see RQl) into the ER framework and efficiently propagate these lower-level belief values to the top-level claims. Implementation of the approach with a scalable tool support is also a major step in this RQ.
