遗传算法在工程项目资源优化中的应用

GENETIC ALGORITHMS IN RESOURCE OPTIMIZATION OF CONSTRUCTION PROJECT

:GA是一种源自生物界自然选择和自然遗传机制的随机化搜索方法 ,群体搜索策略和信息遗传的特点使其在组合优化中表现出其它传统方法所不能比拟的性能 .将 GA应用于工程项目的资源优化中 ,解决资源平衡和资源有限问题 ,避免了繁琐的推断过程 。

Genetic Algorithms (GAs) is a stochastic search method which uses ideas and gets inspirations from the mechanism of natural selection and heredity.Its strategy of population search and characteristics of information transmission make it showing incomparable performance to other traditional approaches in combinatorial optimization.In the paper,GA is applied to resource optimization of construction project.Compared with ordinary heuristic methods,GA can encompass both resource leveling and limited resource allocation problems,prevent petty and multitudinous deducing process and also obtain several secondary optimum solutions as well as the best one.
