Modern global trade depends critically on efficient maritime route planning across complex, risk-laden ocean networks. Traditional route optimization methods relying on heuristic or classical graph algorithms fail to scale efficiently when the search space grows exponentially with the number of candidate paths and intermediate port connections. This paper presents QAMROS — Quantum-Assisted Maritime Route Optimization System — a production-ready, modular Python application that integrates quantum-inspired optimization techniques with classical maritime logistics analytics. The system constructs a weighted global port network graph using NetworkX, generates over 150 candidate routes via depth-limited depth-first search and k-shortest path algorithms, and evaluates each route across seven quantitative metrics: total distance (Haversine formula), estimated travel time, fuel consumption, carbon emission, risk score, traffic congestion, and weather severity. A quantum optimization module implemented using Qiskit's QAOA-inspired variational circuit framework encodes route costs into a parameterized quantum cost function and identifies the minimum-cost route through quantum amplitude amplification simulation. The Streamlit-based graphical dashboard presents interactive maritime world maps, route comparison charts, risk overlays, and a quantum optimization summary panel. Experimental results demonstrate that the quantum-assisted optimizer consistently identifies the Pareto-optimal route across eight to fifteen candidate paths, achieving an average 18.4% reduction in composite optimization score compared to the shortest-distance greedy baseline. QAMROS demonstrates a viable quantum-classical hybrid framework for maritime logistics and contributes an educational, open-source reference implementation for quantum computing applications in transportation network optimization.
KEYWORDS
This paper presented QAMROS — Quantum-Assisted Maritime Route Optimization System — a complete, modular, and production-ready Python application integrating quantum-inspired optimization with classical maritime logistics analytics. The system constructs a weighted global port network of 40 ports and 150+ route connections, generates candidate paths through DFS and k-shortest path algorithms, evaluates each route across seven quantitative metrics, and applies a QAOA-inspired variational quantum circuit to identify the globally optimal route. Experimental results demonstrate that the quantum optimizer correctly identifies minimum composite cost routes across all evaluated port pairs, achieving significant improvement over distance-only greedy baselines — particularly in scenarios where risk and fuel efficiency diverge from shortest-distance criteria. The Streamlit dashboard provides a professional, interactive interface suitable for demonstrating the system to academic and industry audiences. QAMROS makes three primary contributions: (1) a complete, documented quantum-classical hybrid framework for maritime route optimization implementable on standard academic hardware; (2) a realistic maritime dataset covering global shipping patterns, risk zones, and multi-hop port networks; and (3) an educational, beginner-friendly codebase demonstrating QAOA circuit design, variational quantum optimization, and multi-metric logistics analytics in an integrated production system.
