确定控制路线是重复性项目调度技术的基础,目前缺乏一种统一的确定控制路线的方法。本文研究在重复性项目中通过延迟阶跃函数确定控制路线的方法。首先通过延迟阶跃函数拟合重复性项目中的各种类型工序系,表示工序系的约束线,并计算各工序系的潜在控制点和开始、结束时间,在此基础上提出了完整的确定重复性项目控制路线的具体步骤。文章以一个高速公路建设项目为例与国际上已有的确定控制路线的方法进行了对比,结果表明,本文所提出的方法更契合工程的实际要求、适用性更强,且更便于计算机处理。
Determine the control route is the basis of repetitive project scheduling technology, the current lack of a unified way to determine the control route. In this paper, we study the method to determine the control route through the delay step function in the repetitive project. First of all, we use the delay step function to fit the various types of processes in the repetitive project, indicate the constraint lines of the process, and calculate the potential control points and start and end times of each process. Based on this, a complete determination Repeated project control the specific steps of the route. Taking an expressway construction project as an example, the article compares with the existing international methods of determining control routes. The results show that the proposed method is more suitable for the actual requirements of the project and is more applicable and more convenient for computer processing.
