Abstract
The critical path method (CPM) provides the standard approach to scheduling construction projects. Limited crew resources compound CPM analysis by imposing resource availability constraints. However, there is no generalized methodology yet to quantitatively determine the optimal quantities of resources to execute specific work packages based on CPM analysis. Furthermore, in project evaluation and review technique (PERT) simulation, the occurrence of uncertain events is represented by probability distributions for activity durations in an implicit fashion. In this paper, a bi-level project simulation methodology is proposed to (1) determine the optimal resource quantities and activity times for each work package and (2) estimate total project duration and man-hour budget at the upper level for project planning through Monte Carlo simulation, based on defining a limited quantity of likely scenarios for each work package. An industrial plant shutdown and turnaround project serves as case study to illustrate application of the proposed methodology.

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
