An investigation into a sustainable AMS food delivery system
Bibliographic record
Abstract
The new SUB at UBC will be completed December 2014 and is attempting to achieve LEED Platinum certification, a title given to the most sustainable buildings in the world. Not only should this certification refer to the materials used to construct the building and the construction process itself, but it should also influence the operations of the building and its businesses. The current delivery system used by AMS Food and Beverage to transport food throughout the campus is a gasoline powered vehicle. The primary stakeholder for this project, Collyn Chan, the sustainability coordinator of the new SUB, is concerned with the carbon emission of this vehicle and is requesting a recommendation for a more environmentally friendly vehicle to replace the current food delivery vehicle. This task is being investigated by a group of students currently enrolled in APSC 262, whom will determine an environmentally friendly vehicle option that can suitably serve as a food delivery vehicle for AMS Food and Beverage. This report describes a TBL analysis to evaluate which environmentally friendly vehicle would be the most suitable option as a delivery vehicle for AMS Food and Beverage. The three vehicle options compared in this report are a manual bicycle, a fully electric scooter and a fully electric car. Through the TBL analysis, the environmental, economic and social impacts associated with each vehicle’s capability to deliver food were compared. Additionally, the stakeholder also required that the vehicle recommendation be able to travel across campus in a timely manner, protect the deliverer and the food cargo from Vancouver’s weather throughout the entire calendar year and be able to carry at least 100 boxes of pizza in one trip. Only vehicles which were deemed to be relatively environmentally friendly and that met the constraints listed by the project stakeholder were considered in the TBL analysis; any other options were ruled out in a primary stage of the investigation. The result of the TBL analysis of the vehicle options considered determined that a fully electric car, such as the Smart Fortwo Electric Drive, or the Nissan Leaf 2014 SV, would be ideal for delivering food items throughout campus. The recommendation given by this report is that AMS Food and Beverage should replace their current gasoline powered food delivery vehicle with more environmentally friendly fully electric vehicles.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
