Abstract

fetched live from OpenAlex

Traditional risk analysis techniques are ineffective for capturing the dynamic causal interactions and subjective uncertainties involved in assessing risk and opportunity events since they treat risks independently and rely on the availability of sufficient historical data. In this paper, a hybrid fuzzy system dynamics (FSD) model is developed to analyze the impacts of interrelated and interacting risk and opportunity events on work package cost to determine work package and project contingencies using expert judgement and subjective assessment. A fuzzy decision-making trial and evaluation laboratory (DEMATEL) method is employed to structure and analyze the causal interactions among risk and opportunity events. This paper provides the following contributions: (1) a systematic risk assessment and prioritization procedure; (2) a structured method for defining the dynamic causal relationships among risk and opportunity events and quantifying their impact on work package and project contingencies using FSD; and (3) a method for representing linguistic variables and applying fuzzy arithmetic in FSD.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
