An Evacuation Navigation Model Considering Fire's Impact on Escape Capability of Evacuees<sup>*</sup>
Bibliographic record
Abstract
An evacuation navigation model incorporating a fire's detrimental effect on evacuees' escape capability is presented. Fire is one of the most common hazards in buildings that severely impacts evacuees' escape capability. A fire dynamics model is used to simulate dynamics of a fire at various locations in a building. An index, called Capability Deterioration Rate (CDR), is introduced to model how fire effluents, such as smoke, heat, and toxic gases, impact escape capability spatiotemporally. This index is incorporated into a modified Dijkstra algorithm by changing weights of navigation edges. An agent-based model taking into account the fire dynamics and escape capability is used to simulate an agent's evacuation from a location to minimize the total travel cost from the location to an egress door. A three-floor building is used as a case study to demonstrate the application and effectiveness of the proposed model. The proposed model can be used to evaluate and select the best navigation plan in terms of escape capability under various fire scenarios.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
