摘要 　在简要介绍遗传算法机理和基本控制参数的基础上,就如何构造工程项目时间-成本均衡遗传算法的染色体、适应值和群体规模等参数进行了分析,并就如何进行交叉和突变操作作了介绍.构建了工程项目时间-成本均衡遗传算法.发展了现有工程项目资源优化理论,根据文中理论编制的计算机软件,可在工程项目管理实践中推广使用. Firstly, the basic concepts and control parameters of Genetic Glgorithm (GA) are introduced in the paper. Secondly, a method of forming the chromosome of GA for time-cost tradeoff problem in construction projects is suggested. Thirdly, rules for determining the fitness value, as well as the population size, are invented and such skills as crossover and mutation are presented in detail. And finally, a GA-based theory for time-cost tradeoff problem in construction projects is summarized and the computerized system based on this method can be used in practice.
