摘要
本文提出了一种确定重复性建设项目关键路线的新方法。借助约束线,首先给出了工序间存在各种约束条件(时间和距离约束)下潜在关键点的确定方法;为处理大规模项目,进一步提出了与图示法相对应的数值算法。以此为基础,提出了确定关键工序和关键路线的具体步骤,并定义和分析了三种不同类型的关键工序。与现有的方法相比,本文提出的确定关键路线的方法更为准确,适用性更强,而且有利于调度优化目标的实现。
This paper proposes a new method to determine the critical path in repetitive construction project . Firstly, a method is presented to identify the potential critical points by constrained line with various constraints （ time and distance constraints ） in between activities .Then, the method for identifying the critical path and criti-cal activities is proposed .In order to model large-scale projects , this paper further develops a numerical algo-rithm.Three types of critical activities are defined and analyzed .Compared with the existed methods , the proposed method is more convenient , correct, and better for optimization in project scheduling .
