“…This approach reflects generic hierarchical structures of nested layers of constructs that depict multi-level classifications of factors, including structured taxonomies. If studies used this approach to formalize their theoretical bases and were also quantified, they used BBN (Vinnem et al, 2012), DBN (Ashrafi & Anzabi Zadeh, 2017), ABM (e.g., (Nan & Sansavini, 2016), or statistical inference (e.g., (Zhou, Zhao, Liu, & Tang, 2018)) as their quantitative modeling techniques (covered in Section 5). For example, Vinnem et al, (2012) use a combination of generic hierarchical structure and influence diagram (Formalization Type #3) to formalize RIFs (Vinnem et al, 2012) and proceed to quantification using BBN.…”
