Work breakdown structure is the basis of project controlling and the model of duration-cost is put forward with the analysis of time and cost. AHP and FCE is used to weigh the risk of project cost, which is the basis of risk controlling.

• 工作分解结构是项目控制的基础,通过时间成本的权衡分析,提出了工期-成本的数学模型:针对工程项目的成本风险,用层次分析法和模糊综合评价法衡量项目成本风险,为风险控制提供较好的依据。
