Abstract: Aiming at the many uncertain factors involving group projects for telecommunication guarantee engineerings of olympics, considering the fact that the engineering is a complex giant system possessing the typical characteristics of group project management and the resource balance of group engineering project, the use of heuristic algorithms, EXCEL modeling are mainly studied and put forward and the data model on resource balance of group project is established. Empirical studies have shown that this method can effectively solve practical problems involving resource balance of group project for Olympic telecommunication guarantee engineering.
