Abstract: In this paper,a model is founded using Genetic Alg or ithms technique.Genetic operator and facet condition are studied in an arrow net work scheme,and a synthetic distribution is generated by digitizing quantities o f resources(labor, material, mechanics).According to conditions of mult iobjective optimization,a near-optimum solution is obtained.The experiments pro ve it is a method of high speed and high fidelity,and it will be used widely in civil engineering.

Key words: genetic algorithms, digitizing, synthesis distribution, genetic operator

摘要： 建立遗传算法的数学模型,研究遗传算子和求解的边界条件,在双代号网络计划中,将多种资源 (人工、材料、机械 )的消耗数量进行数字化,从而获得多种资源数字的合成分布,按多目标优化的条件,使多种资源均衡使用的数列能够达到最优分布.结果表明,计算速度快,精度高,对技术复杂的大型公路桥梁工程有广泛的运用前景.
