摘要
研究了在绘制单代号网络图时,工序在深度上和宽度上的布置以及工序间折角形箭线在纵向上和横向上的布置问题,给出了它们的具体计算公式,并基于此提出了单代号网络计划图的布图模型.通过开发接口程序,实现了用Access管理网络数据和用AutoCAD打印出图;通过采用方框型来表达事项节点的形式,拓展了单代号网络图的表达信息.
Horizontal and vertical locations of nodes and orthogonal arrow lines between nodes are analyzed when activity-on-node network is drawn, and computational formulas are given to calculate them. A model to layout activity-on-node network is proposed. Interface software is then developed to make it possible for the model to communicate with the software Access and AutoCAD, which improves greatly the data management, maintenance and graph output quality. More information is read from activity-on-node network by using rectangular marks to represent nodes.
