Abstract

fetched live from OpenAlex

Abstract This paper discusses using simulation and optimization to improve the hospital‐internal distribution network, for example, how to schedule and deliver the goods, which items should go on which cart, how to manage the variable consumption in the units, etc. We use a real case to build a simulation model to test various processes and incorporate an optimization algorithm to find the best distribution routes. The results highlight concrete improvements that could be made. These are the use of the same cart for different types of supplies to reduce the number of routes, the reduction of the distribution frequency for certain care units, and the use of optimized routes to reduce the transportation time.

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.
