摘　　要：为了提高建设项目应急预案的针对性,基于改进免疫遗传算法对建设项目应急预案优化进行仿真研究。首先,借鉴生物免疫原理,构建建设项目应急预案优化理论模型;其次,通过设计Taguchi试验优化算法中的重要参数,引入精英保留策略改进免疫遗传算法,并基于该算法构建建设项目应急预案优化模型;最后,以某高速公路为例,运用MATLAB软件进行模拟仿真,测试改进免疫遗传算法的可行性,并设置两组对比实验验证改进免疫遗传算法的优越性。仿真结果表明:相比于传统免疫遗传算法,改进免疫遗传算法下应急预案的亲和度更高,收敛速度也更快。这拓展了项目风险研究,为风险应对决策提供参考依据。In order to improve the pertinence of construction project risk emergency plan,the optimization of construction project risk emergency plan was simulated based on improved immune genetic algorithm.Firstly,based on the principle of biological immunity,the theoretical model of construction project risk emergency plan optimization was constructed.Secondly,by designing the important parameters in the Taguchi experimental optimization algorithm,the elite retention strategy was introduced to improve the immune genetic algorithm,and the optimization model of construction project emergency plan was constructed based on the algorithm.Finally,taking a highway as an example,MATLAB software was used for simulation to test the feasibility of the improved immune genetic algorithm,and two sets of comparative experiments were set up to verify the superiority of the improved immune genetic algorithm.The simulation results showed that the affinity of the emergency plan under the improved immune genetic algorithm is indeed higher than that of the immune genetic algorithm,and the convergence speed is faster.This expands the project risk research and provides a reference for risk response decision-making.
