Optimized Human-Robot Co-Dispatch Planning for Petro-Site Surveillance under Varying Criticalities
Securing petroleum infrastructure requires balancing autonomous system efficiency with human judgment for threat escalation—a challenge unaddressed by classical facility location models. This paper formulates the Human-Robot Co-Dispatch Facility Location Problem (HRCD-FLP), a capacitated facility location variant incorporating tiered infrastructure criticality, human-robot supervision ratio constraints, and minimum utilization requirements. We evaluate command center selection across three technology maturity scenarios. Results show transitioning from conservative (1:3 human-robot supervision) to future autonomous operations (1:10) yields significant cost reduction while maintaining complete critical infrastructure coverage. Optimized planning for human-robot teaming is key to achieve both cost-effective and mission-reliable deployments.

Addressing Gaps in Critical Infrastructure Security
Traditional facility location models fall short in modern critical infrastructure protection. They fail to account for the heterogeneous nature of security resources (humans vs. robots), ignore asset criticality, and lack human-in-the-loop constraints essential for ethical escalation decisions. This creates dangerous blind spots as autonomous fleets become more prevalent, particularly in high-stakes environments like petroleum infrastructure where cyber-physical threats are rising.
A Hybrid Human-Robot Dispatch Optimization Model
Our Human-Robot Co-Dispatch Facility Location Problem (HRCD-FLP) integrates several critical elements previously unaddressed in a unified framework. It considers tiered infrastructure criticality with differentiated service levels, human-robot co-dispatch with supervision ratio constraints (e.g., 1:5 human-to-robot), redundant coverage calibrated to asset vulnerability, and command center capacity constraints. This approach enables optimized strategic facility location and resource allocation for mixed teams.
Optimized Deployment for Cost-Effectiveness & Reliability
The HRCD-FLP framework demonstrates that optimizing human-robot teaming is crucial for achieving both cost-effective and mission-reliable deployments. By relaxing supervision ratios from 1:3 to 1:10, organizations can realize significant cost reductions (up to 27%) and consolidate operations into leaner, high-capacity centers. This quantitative model helps systems engineers evaluate architecture trade-offs, enabling data-driven decisions on facility investment, workforce composition, and service level compliance as autonomy matures.
Beyond Petroleum: Versatile Applications
While developed for petroleum security, the HRCD-FLP model is generalizable to any domain combining distributed assets of varying criticality with mixed human-autonomous teams under supervision constraints. Potential applications include warehouse logistics, where human operators supervise autonomous picking robots; emergency medical services, optimizing ambulance and drone dispatch; defense operations involving human-UAV teams; and smart city infrastructure, managing autonomous patrols and human responders.

Case Study: Petroleum Infrastructure Surveillance
Our model was applied to a simulated large-scale petroleum site complex in Saudi Arabia, with 15 candidate command centers and 50 demand sites across three criticality tiers. We evaluated three technology maturity scenarios: Conservative (1:3 human-to-robot ratio), Balanced (1:5 ratio), and Future (1:10 ratio). Results showed that as the supervision ratio relaxed, the system consolidated from distributed High-level facilities to fewer, centralized centers, achieving significant cost reductions while maintaining full critical infrastructure coverage. This demonstrates the framework's ability to drive strategic architectural shifts based on technological advancements and policy levers.
