Abstract
Modeling the construction supply chain has been a challenge as the construction supply chain is a complex and dynamic ecosystem. To understand the variable and volatile nature of construction, this study developed a system dynamic model to simulate the influences of three key factors, scope changes, requests for information, and rework, on project duration. This study reviewed the latest literature, examined the typical modularized heavy industrial construction projects, sketched a causal loop diagram, developed a system dynamics model, and performed model verification and validation. The simulation results for a simple construction project with artificial input revealed that the three identified factors significantly influenced the project duration against the initial planned project duration. The proposed system dynamics model (1) simulates the multi-stakeholder construction supply chain as a holistic ecosystem; (2) quantifies the impact resulting from inefficient information flows on project duration; and (3) forecasts the project duration given these factors.

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
