In recent years,influenced by artificial and natural factors,all kinds of large-scale public disasters occur frequently,causing serious impact on social stability development.In the face of complex and changeable public disaster events,traditional means of emergency rescue to present clear on the rescue inefficient,rescue measures,some shortcomings,can’t meet the practical requirements,rescue and aviation emergency rescue has fast response speed,strong maneuverability,the characteristics of wide scope of search and rescue,can better adapt to the actual work needs.But at this stage,the aviation emergency rescue network still exists many shortage,not qualified for urban emergency rescue work.So this thesis choose Tianjin as the goal,research on urban aviation emergency rescue sites layout,reasonable layout of the facilities of the candidate points,establish corresponding service relationship between sites,improve overall aviation emergency rescue network rescue efficiency.This thesis obtains from the Tianjin aviation emergency rescue requirement analysis,organizing types and features of public emergencies analysis summary to deal with all kinds of disasters emergency requirements types and aviation emergency rescue work.And on this basis,the establishment of Tianjin aviation emergency rescue sites layout principle,the analysis of factors affecting layout,put forward the aviation emergency rescue sites system layout idea,divided into aviation emergency rescue sites layout later work has a guiding significance.At the same time,analyzed all kinds of emergency facility location model,and based on classical model is improved,the introduction of capacity limits,construction costs,such as the distance decay function constraint,build the improved multi-objective programming layout model,and using the operational research method and genetic algorithm to solve,through the example analysis verify selection to improve the scientific nature and rationality of the model.In determining the model and algorithm,on the basis of generation into the basic data for calculation,get the Tianjin aviation emergency rescue sites layout scheme,namely "1+3+N" aviation emergency rescue sites layout,form a "city aviation emergency rescue center-regional aviation emergency rescue base-emergency rescue helicopter landing point" aviation emergency rescue system network linkage effect,meet the corresponding requirements of all kinds of disasters in practical work,for the rapid response of the aviation emergency rescue and effective linkage to provide strong support,other cities for the future aviation emergency rescue sites layout work provide certain reference value. |
