Abstract
The simulation model used in this study is based on a construction project in Taiwan. In this study, STROBOSCOPE and EZStrobe were used as discrete-event simulation software to assess the potential risk of the construction in terms of time and cost. The construction process, the unit cost of the resources, and the operation time of each activity were modelled based on the actual construction procedure. A total of 30 replications was required for each scenario. Scenarios with real-world data inputs and eight other models were simulated using the software. The best scenario with the lowest cost and competitive time was selected as the base model for a sensitivity analysis. During the Sensitivity Analysis, the best model 8-R was generated by changing the number of labourers to 13 and Excavators to 3. Compared to the real-world project, the total costs were reduced by 11% and the total time was reduced by 58%. Moreover, the result of risk analysis based on scenario 8-R demonstrated that using a number of labourers, trucks, excavators, rollers, millers, and pavers less than the quantities that were used in the real-world data, the associated risk in term of cost and time will exceed the real-world project cost.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
