Local Producer Marketplace

A digital marketplace connecting local producers and consumers in the Baia Mare region, and a real-world testbed for COSA supply-chain optimization research.

About the platform

The Local Producer Marketplace is a digital platform that connects local producers in the Baia Mare region with consumers and generates high-quality, real-world data for the COSA research team. Built around the Short Food Supply Chain (SFSC) model, the platform aggregates multiple local producer storefronts into a single, searchable ecosystem, a “marketplace of marketplaces”.

What the platform delivers

  • For consumers: a unified interface to browse, compare, and buy from local producers, with a shared shopping cart and home delivery options.
  • For producers: a personal branded storefront, inventory management, order tracking, sales analytics, and promotion tools — with zero technological barriers.
  • For research: real-world transaction, location, demand, and temporal data as input for vehicle-routing and supply-chain optimization research within COSA.

Team and partner

Lead developer: Cosmin Sabo. Research team: COSA project consortium. Hosting institution: Technical University of Cluj-Napoca, North University Center of Baia Mare.

Research context

The marketplace provides a unique source of real-world data for several classes of optimization problems studied within COSA, Vehicle Routing Problem (VRP), Capacitated VRP, Time-Windows VRP, and Multi-Depot VRP — using AI and metaheuristics, including hybrid genetic algorithms, clustered routing approaches, and evolutionary encodings published by the COSA team in EJOR, Carpathian J. Math., and other venues.

A Comparison of different crossover operators in genetic algorithms for clusters shortest-path tree problem

The clustered shortest-path tree (CluSPT) problem is an extension of the classical shortest path problem, given a graph with the nodes partitioned into several mutually exclusive and collectively exhaustive clusters looks for a shortest-path spanning tree from a predefined source node to all the other nodes of the graph, with the property that every cluster should generate a connected subgraph.
