摘　　要：作为一项较复杂的工程项目,其每道工序的完工时间常常是不确定的,文章利用β分布、正态分布对较复杂的工程项目作出科学合理的分析,结合统筹图找出工程项目的关键路线,并以较大的概率保证整个工程完工时间的合理性.文章的研究对较复杂工程项目的管理具有科学的指导意义.As a complex engineering project, the time for finishing every process of the project is uncertain. By using β distribution and normal distribution, this paper makes scientific and rational analysis of some relatively complex projects, uses overall chart to try to find the key lines of the projects and uses bigger probability to ensure the rationality for the finishing time of the whole projects. The research in this article is of scientific guiding significance to the management of relatively complex projects.

关 键 词：工序 β分布 正态分布 统筹图 完工时间
