Study on the optimization of natural gas station inspection paths considering station priority
This analysis of 'Study on the optimization of natural gas station inspection paths considering station priority' highlights a critical need in the energy sector: enhancing inspection efficiency and safety at natural gas stations. Traditionally hampered by manual planning, a disregard for equipment priority, and uncoordinated objectives, current methods are costly and leave high-risk assets vulnerable. This research pioneers an AI-driven, multi-objective optimization model, integrated with a hybrid Genetic-Simulated Annealing (GA-SA) algorithm, to radically transform inspection path planning. By balancing economic efficiency with safety priorities, the model achieves substantial reductions in operational costs and significant improvements in risk coverage, validated through a comprehensive simulated case study.

The Challenge: Inefficient Manual Inspections
As global energy demand rises, ensuring the security and stability of natural gas supply chains becomes paramount. Natural gas stations, vital infrastructure nodes, currently face challenges in efficient inspection due to dispersed equipment, varying priorities, and reliance on manual methods. This leads to low efficiency, high costs, and inadequate coverage of critical assets, ultimately compromising safety. While intelligent technologies like drones are emerging, manual inspection remains essential, necessitating advanced optimization strategies.
Model Design: Multi-Objective Optimization
This study addresses the Vehicle Routing Problem (VRP) for natural gas station inspections. The core objective is to simultaneously minimize total inspection costs (fixed vehicle usage + travel distance) and maximize priority satisfaction. A novel priority satisfaction function incorporates a time-decay coefficient, ensuring that high-priority stations are inspected promptly. The model considers practical constraints such as limited vehicle numbers, maximum travel distance per vehicle, and single-visit coverage for all inspection points, reflecting real-world operational demands.
The Solution: Hybrid GA-SA Algorithm
To effectively solve this NP-hard multi-objective optimization problem, a hybrid Genetic-Simulated Annealing (GA-SA) algorithm is proposed. This approach combines the global exploration strength of Genetic Algorithms (GA) with the local refinement capability of Simulated Annealing (SA). GA-SA employs a double-chain chromosome encoding, dynamic mutation rates that adjust with temperature, and the Metropolis criterion for offspring selection, enabling it to efficiently escape local optima and converge to a stable Pareto-optimal solution set, balancing conflicting objectives.
Quantitative Impact: Optimized Performance
A simulated case study, based on real-world operational characteristics, validated the GA-SA model. The optimization significantly improved efficiency and reduced costs compared to traditional manual planning: a 20.70% reduction in total inspection costs, a 17.71% decrease in total mileage, a 14.59% reduction in inspection time, and a 25% reduction in vehicles deployed. Crucially, priority satisfaction increased by 5.33%, demonstrating enhanced coverage of high-risk equipment, aligning economic goals with safety imperatives.
Parameter Insights: Robustness & Tunability
A sensitivity analysis was performed on key model parameters. The priority decay coefficient (β) and the cost weight (ω1) in the fitness function were identified as the most influential, allowing decision-makers to fine-tune the balance between cost and safety priorities. A higher β (e.g., 0.05) accelerates priority decay, ensuring high-risk stations are prioritized, while adjusting ω1 shifts emphasis between cost minimization and satisfaction. Maximum travel distance (Dmax) and algorithm temperature decay coefficient (α) showed stable effects within recommended ranges, confirming the model's robustness and providing practical guidelines for configuration.
Strategic Recommendations for Implementation
Based on the research, key recommendations include: promoting the adoption of optimization algorithms with professional training for personnel; enhancing foundational data infrastructure with dynamic updates for locations, priorities, and traffic; establishing continuous improvement and emergency response systems to adapt to dynamic conditions; and advancing supportive policy for AI integration and talent development. These steps will facilitate intelligent decision-making, balancing economic and safety considerations in natural gas station inspections and providing a blueprint for multi-objective path optimization in complex industrial settings.
