Logistics as a Service (LaaS)
The Deterministic VRP Solver

Stop buying unnecessary trucks. Cut your fleet size and eliminate hidden OPEX with the world's first 100% zero-variance routing core. Master complex VRPTW constraints, and scale enterprise logistics (CVRP, MDVRPTW) up to 10,000 nodes instantly.

Why Enterprise Logistics Choose a Deterministic Solver?

Reduce Costs. Guarantee Stability.

Reduce Delivery Costs

Stop wasting fuel on suboptimal routes. Our engine compresses distance with absolute precision, eliminating the extra miles caused by metaheuristic "guesswork."

Optimize Fleet Routing (Zero Variance)

Unpredictable algorithms make KPI planning impossible. GSL-Solver guarantees 100% stability. Run the same data 1,000 times, get the exact same optimized route.

Minimize Fleet Size

Advanced K-Focus structural framework mathematically minimizes vehicle fleet sizes before route optimization, drastically reducing fixed operational costs.

The Engineering Advantage

Geometric Sensing

Advanced structural framework minimizes vehicle fleet sizes (K-Focus) before route optimization, drastically reducing fixed operational costs.

Zero-Tuning Policy

Fully deterministic architecture. No stochastic variance, no parameter guessing. Yields consistent, auditable, and feasible solutions every single execution.

Zero-Infrastructure Integration

Eliminate the need for costly on-premise servers and specialized IT overhead. Our engine is accessible directly via web-interface or API.

REAL-WORLD INDUSTRIAL VALIDATION

Bosnia & Herzegovina Network

Validated against complex open-source industrial datasets (Žunić, 2020). Outperformed the company's legacy routing baseline (537.43 KM) by addressing asymmetric networks, strict 2D capacity, and high-density time windows.

Empirical Proof: Beating BKS

Instance: XL-n10001-k1570 (10,001 Nodes)

GSL Engine: 2,332,319.27 (Gap: -0.06%)

Achieved negative gap against Best Known Solution. 100% Deterministic. Beats traditional Metaheuristics (LNS) by over 4% in fuel efficiency.

800-Node VRPTW Stress Test

Instance: c1_8_1 (Homberger)

GSL Engine: 80 Vehicles (Matched BKS) in 32.4s

The Metaheuristic Failure: Standard ALNS required 106 Vehicles (+26 extra trucks) and took over 3.5 minutes. GSL saves massive CAPEX.

Cordeau Benchmark

Module: MDVRP (p-series)

Execution: Sub-second

Achieved high-quality deterministic results. Example: p05 (100 nodes) solved in just 0.131s.

Live Demonstration: MDVRPTW Solver (780 Nodes) - Processed in 9.8 Seconds

THE ENTERPRISE IMPACT

Stop Paying for Algorithmic Guesswork

Results from the standard 800-Node VRPTW Stress Test (c1_8_1 benchmark). Solving the exact same delivery network.

❌ Legacy Metaheuristics (ALNS)

Fleet Required: 106 Trucks
(Wasting ~$1.3M/year in hidden OPEX)

Processing Time: 3.5 Minutes

Logic Stability: High Variance / Unpredictable


Financial Impact: Paying drivers for unnecessary routes and burning massive fuel budgets.

✅ GSL Deterministic Engine

Fleet Required: 80 Trucks
(Eliminates 26 trucks. Recovers SaaS cost in 7 days.)

Processing Time: 32 Seconds

Logic Stability: 100% Zero-Variance


Financial Impact: Avoids $1.3M annual fleet waste. Rock-solid operational predictability.
