Identification and prioritization of hazardous material transportation strategies using DEA method
Bibliographic record
Abstract
Development of industries needs expansion of public transportation and, consequently, heavy transportation increases hazardous and dangerous transportation too. Therefore, we need to consider some strategies to reduce bad effects of transportation of hazardous materials such as road accidents. Strength, Weakness, Opportunity and Treats (SWOT) analysis is an applicable method for designing strategies in this area. However, SWOT analysis does not provide specific strategies and it does not consider the efficiency and performance of each strategy. Applying a hybrid method of analyzing the strategies and their performance evaluation help decision makers select the best strategies based on the current limitations. In this paper, different strategies for hazardous transportation risk reduction are designed and relative efficiencies of all alternatives are compared using DEA method. The proposed model of this paper uses three inputs including implementation costs, operation and maintenance cost and operational and four outputs including accident rate reduction, fuel consumption reduction, employment rate increment and deaths number reduction. The results of the implementation using seven different strategies have yielded two important strategies including continuous improvement of vehicle standards, driving skills, transportation system quality, and loading methods and expansion of petroleum pipe network.

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.
