1957年5月7日，Kelly利用线性规划的概念，通过计算机自动计算项目的工期，引入了节点表示活动间的逻辑关系，从而产生了最早的箭线图（Arrow Diagram Method, ADM）。1959年，Kelly和Walker共同发表了“Critical Path Planning and Scheduling”论文，详细阐述了关键路径法的基本原理，包括资源分配与平衡、费用计划的方法 。

The tasks are plotted on a network activity diagram as seen in Figure 1. These diagrams illustrate the tasks that need to be completed. Figure 1 - This is an example of a CPM diagram. The most important elements in a network activity diagram are the dependent tasks. These steps allow for...
The first path is for the largest building, the second is for the medium-sized one, and the third is for the smallest building. Now, let us review the diagram for Critical Path Analysis. Did you notice that the first path is the longest?
(b) The principal wants to use a diagram to represent the sequence and the duration of the list of tasks to be done. He uses the following symbols to construct the diagram: An arrow indicates a task. It is labeled with the task name (A, B, C, etc.) and the number (in weeks) ...
The diagram illustrates the degree of flexibility in starting activities B, C and G. Remember that G cannot be started until C has been completed. Image The diagram shown is known as a cascade chart or Gantt chart. PROGRESS CHECK Image...
This diagram also brings out a number of other important points: Within Critical Path Analysis, we refer to activities by the numbers in the circles at each end. For example, the task "Core Module Analysis" would be called activity 2 to 3. "Select Hardware" would be activity 2 to 9. ...
Monitor progress and edit:The CPA chart can be used to monitor progress and should be updated as the project progresses. Once an activity is complete, update the diagram with the time it took. These changes will be reflected in the critical path and potentially change the estimated completion ...
Critical path method applied to research project planning: Fire Economics Evaluation System (FEES) The critical path method (CPM) of network analysis (a) depicts precedence among the many activities in a project by a network diagram; (b) identifies criti... EB Anderson,Hales, R. S 被引量:...
