ACADEMIC CONTRIBUTION

This project demonstrates that known algorithms from computational geometry (Haversine), multi-objective optimisation, and demand-aware pricing can be applied to a novel three-sided logistics marketplace domain where no such solution previously existed in Estonia.

The combination of a production-ready logistics marketplace and explainable algorithmic components makes Saya suitable both as a commercial platform and as an academic research project in the areas of:

• Geo-aware courier matching using geographic distance optimisation

• Multi-objective courier recommendation and offer ranking

• Dynamic pricing assistance for logistics marketplaces

• Machine-learning-based ETA prediction for delivery planning

• Logistics analytics and explainable operational metrics

• Intelligent decision support for customers, couriers, and administrators

The platform combines traditional software engineering practices with algorithmic optimisation and machine-learning techniques to improve logistics efficiency, recommendation quality, pricing transparency, and delivery planning.
