Abstract
In this paper, we present a mixed integer fuzzy programming approach to scheduling of customer orders for various furniture styles. Jobs are grouped into multiple classes based on different factors such as fabric type, furniture style and order due dates to reduce number of setups. The family of jobs at each stage of operation can also be partitioned into batches, where each batch consists a set of consecutively processed jobs from the same class. If a batch is assigned to one of available parallel machines, a setup is required at the beginning of the first job in that batch. A schedule defines how batches are formed at each stage and specifies the processing order of the batches and that of the jobs within the batches. A machine can only process one job at a time, and cannot perform any processing while undergoing a setup. The proposed formulation minimizes the total weighted flow time while fulfilling due date requirements. Numerical experimentation reveals that the proposed solution approach can efficiently schedule up to 16 jobs

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
