Strategic Planning of an Inter-connected Crowd Logistics Network
Bibliographic record
Abstract
There is a growing market for crowd-shipping, which hires people to transport packages on their regular commutes, in the Greater Toronto Area (GTA). This thesis considers a hybrid crowd-shipping operation that hires crowd-shippers and regular drivers in a physical internet environment. The spatial distribution of potential crowd-shippers is analyzed by leveraging a behaviour model and data that combines 2016 Transportation Tomorrow Survey (TTS) data and census data. An inter-connected crowd logistics network is designed to serve business-to-consumer (B2C) logistics demand through solving a parcel locker location routing problem (PLLRP) that optimizes the placement of parcel lockers and the movements of parcels. Finally, the service levels of the proposed network are estimated. The numerical results reveal that an inter-connected crowd logistics network can provide more stable and cost-effective services when the demand level is higher. The hiring of regular drivers is necessary to service some regions with low crowd-shipper supply.

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.
