Abstract

fetched live from OpenAlex

The Health Sciences Centre (HSC) in Winnipeg handles a large portion of the surgical patients in the province of Manitoba, along with Northwestern Ontario, and Nunavut. After an extensive analysis of the surgical patient flow at the facility, it became evident that the Operating Room (OR) scheduling system is one of the major sources of artificial variation in this flow, affecting both the pre and postoperative departments. A two-stage multi-objective mathematical model is proposed for the scheduling of elective cases. Using data obtained from all elective cases actually scheduled during a five week period at the HSC, five weekly OR schedules are generated using the first stage of the proposed mathematical model. The results of the model’s schedules are compared to current schedules employed at the HSC, to verify its effectiveness and assess the improvements that can be achieved.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
