摘　　要：项目工期受较大的不确定性因素影响,故应用不确定理论来描述工期-费用优化问题。考虑到实际工程项目中工序间存在的搭接关系,将搭接关系表示为延迟时距引入工期计算式中,进而构建考虑延迟时距的不确定工期-费用优化模型。同时,我们给出并证明模型的等价形式,并用于原模型的求解。最后,通过工程案例验证模型的有效性。This paper applies the uncertainty theory to the time-cost trade-off problem due to various uncertain factors in real project.In practice,the overlapping relationships among some activities usually exist in the project.In order to simplify the calculation,the relationships are converted into the delay time and introduced to the formula of the project time.Then,the uncertain time-cost trade-off model with delay time is built.Meanwhile,the equivalent form of the uncertain programming model is given and proven to solve the proposed model.Finally,a project case is used to illustrate the effectiveness of the proposed model.
