优选法在院前急救行驶路径选择时的运用

目的：根据优选法理论,设计试验方法,通过试验的办法来寻找各种因素的最佳点,运用优选法对院前急救行驶路径进行最佳选择。方法：确定运用时的优选问题,即最优化问题,用数值方法或试验最优化等直接方法求解（直接优选）。采用相同时间段,三条试验范围内行驶路径的10次试验行驶记录,将有关数据进行统计分析。结果：将数据计算结果进行比较排列,试验路径所需时间（min）S2〈S1〈s3,均值比较（P〈0．05）。结论：运用优选法理论,通过试验的办法来确定院前急救路线最佳选择,有一定临床应用价值。

The application of the optimization in prehospital emergency driving pathway route choice

Objective：The purpose of this paper is to find the best point of various factors for the prehospital e- mergency treatment for driving path for the best choice by applying to optimization theory through the test meth- od. Method：Make sure when using the optimization problem, that is, the optimization problem, use the direct meth- od of numerical method or test optimization co solve （direct optimization）. At the same time, 10 times test driving record in the three test range driving route,make the relevant data to statistical analysis. Result：The research is to compare and arrange the results of data, the required time of the test path（min）S2〈Sl〈S3,the mean value com- parison （P〈0.05）. Conclusion：The research is of certain clinical application value by using the optimization theo- ry,through the test method to determine the best choice of prehospital emergency treatment line.
