The critical path can be determined by use of either the "forward pass" or the "backward pass."False (Project management techniques: PERT and CPM, moderate) 相关知识点: 试题来源: 解析 False 关键路径的确定需要同时使用正推法(forward pass)和逆推法(backward pass)。正推法计算活动的最早开始...
在项目管理中,**后进路法(backward pass)**用于计算活动的最晚开始(Late Start, LS)和最晚完成(Late Finish, LF)日期。具体分析如下: - **A. 关键路径**:关键路径通过浮动时间为零的路径确定,虽然后进路法辅助这一过程,但并非直接目的。 - **B. 最早完成日期**:这是通过**前进路法(forward pass)**计算...
Backward Pass Critical Path Formulas The backward pass begins by using the largest EF for the last activity, the value that marks the time required to complete the project, as the LF for the activities is closest to the finish. To find their LS, the duration of those tasks should be ...

📌Remember: Just like calculating early start/finish, you still need to account for resource availability when doing the backward pass. Best Tools for Calculating the Critical Path Below, we’ll take a glance at some CP software, templates, and diagram generators available on the web to help...

Backward pass:Calculate each task's latest start (LS) and latest finish (LF). Start with the final task, which will have an LF equal to its EF, and move backward, subtracting task durations. Slack time:For each task, subtract its ES from its LS (or its EF from its LF) to determine...
TheBackward Passis a Critical Path Method techique you can use to determine the latest date an activity can start and the latest date it can finish before it delays the project. You'll start once again with the critical path, but this time you'l begin from the last activity in the path...
You can also identify critical activities with the Forward Pass/Backward Pass technique, identifying the earliest start and finish times, and the latest start and finish times for each activity. If you have multiple critical paths, you will run into network sensitivity. A project schedule is consi...
Forward pass: This calculates each activity's earliest start and finish times, ultimately leading to the overall project duration. Backward pass: This step calculates each activity's latest start and finish times, enabling the project manager to identify the activities with the least flexibility. ...
