| 摘 要： | 提出了一种基于灾害发生概率、灾害扩散函数和救援函数的救援中心选址优化的数学模型.由于灾害的扩散和救援的功效都只能表达为时间的非线性函数,这种嵌入时间函数的优化问题很难由一般数学规划模型求解.提出一种基于嵌入启发式遗传算法作为模型求解方法.通过对大量源于实际的算例进行计算,取得了满意的结果.

| Abstract: | Proposes a mathematical model to optimize the location of catastrophic rescue center,taking account of the probability of catastrophic occurrence,catastrophic diffusion function and rescue function.Because the catastrophic diffusion and rescue functions are both nonlinear and time-variable,they are very difficult to be solved by way of common mathematical programming.A heuristic embedded genetic algorithm is therefore developed to solve the special model.The computation of a large number of examples arising from practice provide satisfactory results. |
