Model Of The Dual Objective Function For The Ground Search Planning Research And Practice

Destructive earthquakes, to people's life and production caused heavy losses. But it is inevitable and prediction of low level features, so, after the earthquake to rescue trapped quickly, become relief of the primary task, also be lessened by the earthquake disaster caused casualties were important measures. How to improve the efficiency of earthquake disaster search and rescue operations, in a shorter period of time to save the life of more victims? The effective use of existing resources, reasonable make search and rescue scheme and searches for a route to improve the rescue efficiency plays an important role in.According to the need of the problem, this paper introduces the related concepts of linear programming model, general expressions and solving methods, and emphatically introduces the contains two variables of double objective function model of planning graphic method and its application in production. In order to rescue force reasonable deployment, this paper analyzes the necessity and the deployment of construction elements, developed a rescue force optimization allocation principle [13], in accordance with the search and rescue task average distributive principle, met search task amount minimum average allocation scheme; according to the trapped density search principle, met the promoter region number for search weight allocation scheme.The search team in the search area of the route, this paper firstly the affected areas to conduct search priority analysis, will search the area for polygonal approximation. On the local search problems, is used for a single rectangle and triangle are given in the search area search route; the transfer problem, select regions of each vertex as the region between the possible conversion point, considering the road traffic, respectively, between cities and regions are given the transfer between arbitrary points the transfer price, established the regional transfer between minimum cost as the goal of the transfer route optimization model.Finally, taking 5.12 Wenchuan earthquake as background, discusses the ground search problem. For search and the search range of the actual situation, put forward reasonable assumptions, in order to achieve the time used in the search, and search the least time optimization goal, as far as possible when searching for steering at least, establish the double objective function planning model, combined model corresponding constraint condition, using mathematical software to solve the optimal solution, thus, personnel grouping and grid distribution, optimal search performance, to achieve the target search and rescue. The model further discussion, establishment of the test model of search is best done more in-depth study.
