【Abstract】 This paper analyses the defects of genetic algorithm of resource smoothing in project activity networks. The clustering analysis genetic algorithm for the optimization is proposed. Because the group of seed is optimized to classification, the searching radius is reduced continuously. The self- adaptive and continuous optimum search is realized. The convergence speed, the accuracy of solutions and the capacity of global search in networks have greatly improved. The improving algorithm shows that the method is very efficient for large project networks. This is a practical method and it can be used, to practical project construction management.更多还原
