Flood Property Placement Routing Under Dynamic Water-Land Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for property placement in flood evacuation lack consideration for dynamic mutual feedback relationships among 'water', 'objects', and 'land', leading to inefficient and unsafe transfer routes due to reliance on hypothetical scenarios, underutilization of evacuation areas, and lack of real-time adjustments.
Innovation Solution
A dynamic mutual feedback-based method using GIS and hydrodynamic modeling to generate flood inundation maps, delineate risk and safety zones, construct accessible road networks, and employ heuristic optimization for optimal property transfer routes, incorporating grid-based transfer, classified transport, and dedicated-area placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional preset scenario methods are used for property placement, then evacuation plans can be formulated in advance, but the methods lack adaptability to real-time flood conditions and dynamic feedback relationships
Solution Approach 1:
The patent implements dynamic evacuation route adjustment by continuously updating the evacuation plan based on real-time flood risk information. The system dynamically modifies transfer routes, placement sites, and evacuation schedules according to changing flood conditions, transforming the static preset scenario approach into a dynamic adaptive system that responds to real-time feedback from water, objects, and land interactions.
Solution Approach 2:
The patent establishes a feedback mechanism that incorporates real-time flood risk information into the evacuation decision-making process. The system receives feedback from flood monitoring data, property status, and road conditions, then adjusts evacuation plans accordingly. This closed-loop feedback system enables the evacuation method to adapt to actual flood conditions rather than relying solely on hypothetical scenarios.
2Reliability
If established transfer routes are used without real-time adjustment, then evacuation procedures remain simple, but the routes become potentially unsafe or unfeasible when flood conditions change
Solution Approach 1:
The patent performs preliminary actions by pre-establishing multiple feasible transfer placement route sets based on grid-based transfer rules and classified transport principles before flood events occur. The system pre-identifies potential routes and placement sites, so when flood conditions arise, the system only needs to select and adjust from pre-prepared options rather than creating routes from scratch, reducing adjustment time while maintaining safety.
Solution Approach 2:
The system dynamically adjusts established routes by continuously monitoring flood conditions and modifying transfer routes in real-time. When flood levels change or road conditions deteriorate, the system automatically recalculates safe routes and updates evacuation schedules, ensuring route safety without requiring complete plan redesigns from scratch.
3Productivity
If multiple properties are placed in the same area, then evacuation implementation is simplified, but evacuation areas become underutilized and resettlement efficiency decreases
Solution Approach 1:
The patent segments properties into different categories based on type, value, and evacuation urgency. The system divides properties into groups such as critical infrastructure, important documents, and general belongings, then assigns different evacuation priorities and placement strategies to each segment. This segmentation enables more efficient use of evacuation areas by matching property types with appropriate placement locations rather than consolidating all properties in one area.
Solution Approach 2:
The patent applies local quality principles by assigning different evacuation strategies to different property types and locations. The system considers local characteristics such as property importance, location proximity to flood zones, and placement site suitability to determine optimal evacuation approaches. This localized approach maximizes evacuation area utilization by placing different property segments in the most appropriate locations rather than uniform consolidation.
4Productivity
If properties are not categorized for transport, then evacuation operations remain simple, but transfer routing becomes inefficient
Solution Approach 1:
The patent segments properties into distinct categories based on characteristics such as type, value, and evacuation urgency. The system classifies properties into groups like critical infrastructure, important documents, and general belongings, enabling differentiated transport strategies for each segment. This segmentation improves transfer routing efficiency by allowing optimized path selection and resource allocation for different property types.
Solution Approach 2:
The patent changes operational parameters based on property categories. The system adjusts transport mode, route selection, and evacuation timing according to property type and urgency levels. By varying these parameters across different property segments, the system achieves efficient transfer routing without requiring uniform treatment of all properties, balancing operational simplicity with routing optimization.
