Dynamic emergency route planning for major chemical accidents: Models and application

Combining scenario construction with the characteristics of individual emergency behavior is necessary for route planning major chemical accidents. We investigated this challenging decision problem and constructed a multi-indicator risk assessment method that considers evacuation speed different population types health consequences caused by various components. also designed modified Dijkstra algorithm to solve dynamic multi-objective problem. The comparative experiment results demonstrated proposed performs relatively better than traditional algorithm. Finally, we performed extensive case studies where our simulation demonstrate model provides reliable practical services personnel under accident scenarios. Compared commonly used single-dimensional method, comprehensive informative risks faced in regions could serve as useful reference formulation implementation plans
