| 摘 要： | 文章研究在失踪旅游者搜索问题中引入最优搜索理论的方法。针对失踪者相对静态的情况，在目标分布函数与探测函数的基础上建立搜索模型，通过拉格朗日乘数法最优化计算，导出了探测函数服从指数形式时的静态失踪旅游者最优搜索模型和搜索资源最优配置的计算方法。经示例比较，研究建立的搜索模型大幅度缩短了失踪旅游者的搜索时间，提高了搜索效率与失踪者的生还机会。

| Abstract: | The use of optimal search theory in the search model of disappeared tourist is deduced. The optimal search model is deduced by using Lagrange multiply method based on the search model which is established on the objective function and detection function. The experiment shows the effectiveness of the approach, and the optimal distribution model of searching efforts minimizs the mean time to find the disappeared, and maximizs the probability of finding it. |
