问题描述
您好，
这是我第一次发帖。我搜索并看到很多关于负面松弛的好消息，但没有解决我的具体问题。
This is my first time posting. I searched and saw a lot of great info on negative slack, but not anything that addressed my specific issue.
我有一个任务显示-70d总松弛。任务没有继任者。
I have a task that is showing -70d of total slack. the task does not have a successor.
我正在尝试找到关键路径的任务的人为提前截止日期。
I have an artificially early Deadline on the task I am trying to locate the critical path to.
项目结束日期是任务结束日期后2年，负面松弛。
The project end date is 2 years after the end date of the task with negative slack.
我迷失了为什么如果不驱动任何后继者，任务会有负面松弛吗？
I am lost as to why a task would have negative slack if it is not driving any successors?
对于任何可以帮我解决这个恼人问题的人，我都非常感激！
I would be much obliged to anyone that can help me resolve this annoying issue!
谢谢！
迈克
推荐答案
负的总松弛是由任务的完成日期滑过截止日期或硬约束日期（例如完成不迟于约束）引起的。 因此，在您的情况下，我会说错过截止日期是原因。 希望这会有所帮助。
Negative Total Slack is caused by a task's Finish date slipping past its Deadline date or a hard constraint date (such as a Finish No Later Than constraint). So, in your case, I would say the missed Deadline date is the cause. Hope this helps.
