重复性建设项目中确定关键路线的方法研究

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。

Critical Path Identification in Repetitive Project Scheduling

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 critical activities is proposed. In order to model large-scale projects, this paper further develops a numerical algorithm. 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.
