Abstract
Effective evaluation of the productivity and safety of manual operations is essential for successful planning of operations as well as for workplace design. However, actions employed by production planners to improve productivity might adversely impact the ergonomic safety of workers. To address this issue, methods and tools are required that enable simultaneous evaluation of the efficiency and safety of operations. Thus, this study proposes an approach that integrates predetermined motion time systems and ergonomic assessment into a discrete-event simulation environment, and uses inputs obtained from point cloud and 3D models of a workplace to analyze both the productivity and ergonomic safety of manual operations. The proposed approach facilitates the evaluation and improvement of efficiency and ergonomic safety of manual tasks by automating the analysis and eliminating the need for onsite measurements and observations, all without the need for extensive prior knowledge regarding how PMTSs and ergonomic assessment methods work.

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
