Typical deterministic methodologies include threshold methodologies , indicatorbased methodologies , and numerical simulation methodologies . These deterministic methodologies aim to obtain deterministic results from data, analytical analysis, or numerical analysis, which can be effectively used to develop "rules of thumb" or as a screening tool for the preliminary assessment of accident consequences, possible escalation scenarios or personnel exposure damage . However, deterministic methodologies cannot capture the uncertainties associated with complex engineering application scenarios . The obtained deterministic results are usually case-dependent. Thus, different and apparently conflicting results may be obtained due to different observations .
