摘要
论文概括了双代号网络图绘制中虚箭线和开始节点运用条件,提出一种开始节点"先加后减"的绘制方法,能有效降低分析难度,提高绘制速度。
The application conditions of the dummy arrows and the start node in the double code network diagram are summarized, and a new drawing method is presented that named ＂starting node first add then substract＂ . It can reduce the difficulty of analysis and increase the speed of drawing.
