| Abstract: | 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. |
