Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of disaster relief rescue path planning, and specifically provides a method and system for optimizing disaster relief rescue path planning and methods based on a large model. Background Art
[0002] Limitations of traditional disaster relief rescue path planning and method optimization:
[0003] Difficulties in information acquisition and integration: Traditional disaster relief rescue relies on single data sources such as manual reporting and satellite remote sensing, which have problems such as information lag, limited coverage, and inconsistent data formats, making it difficult to comprehensively and timely grasp the dynamics of the disaster area in real time. There is a lack of an effective integration mechanism for data from different sources (such as meteorology, traffic, social media), resulting in information silos and affecting the accuracy of decision-making.
[0004] Insufficient disaster trend prediction ability: Traditional methods rely on historical experience or simple statistical models and are difficult to capture the complex evolution laws of disasters (such as secondary disaster chain reactions and dynamic changes in resource requirements). There is a lack of accurate prediction of the disaster impact range and duration, leading to unreasonable allocation of rescue resources and delaying the best rescue opportunity.
[0005] Low path planning efficiency: Traditional path planning relies on static maps and cannot respond in real time to changes in road conditions (such as road damage and traffic control), resulting in detours and congestion of rescue vehicles and reducing rescue efficiency. There is a lack of multi-objective optimization ability (such as time, cost, safety), and it is difficult to generate the optimal path under complex constraints (such as limited resources and prioritizing the rescue of high-risk areas).
[0006] The decision support system has a single function: Traditional decision support systems are mostly based on rule bases or simple models and lack intelligent analysis capabilities, making it difficult to handle complex and dynamic disaster relief scenarios. There is a lack of a visual interface and simulation function, and it is difficult for decision-makers to intuitively understand the disaster situation and evaluate the effectiveness of the plan, resulting in a decline in decision-making quality.
[0007] The feedback mechanism and dynamic adjustment are lagging: Traditional systems lack a real-time data monitoring and feedback mechanism and cannot timely perceive changes in the disaster area (such as new disaster points and resource exhaustion), resulting in a disconnect between rescue strategies and actual needs. Dynamic adjustment relies on manual intervention, with a slow response speed and difficulty in adapting to the rapidly changing disaster relief environment. Summary of the Invention
