For example , if two tasks can start at the same time , they are linked with a start - to - start dependency 譬如,如果两个项目可以同时启动,则链接为开始-开始( ss )相关性。
Tasks that have a start - to - start link and tasks with lead time are two kinds of tasks that can have overlap time 具有重叠时间的两种任务是:具有开始-开始类型链接的任务、带有前置重叠时间的任务。
After you ' ve linked the tasks , however , you can change the link to a start - to - start , finish - to - finish , or start - to - finish link 不过,在链接任务后,可以将链接更改为开始-开始、结束-结束或开始-结束链接(也可以指定前置重叠时间和延隔时间) 。
Tasks linked with a finish - to - start ( fs ) link add more time to a project ' s duration than tasks linked either with start - to - start ( ss ) or finish - to - finish ( ff ) links 使用完成-开始( fs )链接的任务要比使用开始-开始( ss )链接或完成-完成( ff )链接的任务使项目工期增加的时间多。
* * * * with a start - to - start ( ss ) link , the task begins when its predecessor begins . for more information about task relationships , see chapter 5 , " getting tasks done in the right order , at the right time . 关于任务相关性的详细情况,请参阅第5章“按恰当的顺序和时间完成任务” 。
You might find that you can overlap tasks so much that they start at the same time . if that ' s the case , you should consider changing the fs link to a start - to - start ( ss ) link , instead of adding lead time 有时重叠的时间非常多,结果是它们同时开始,如果这样,请将fs链接改为开始-开始( ss )链接,而不是添加延隔时间。
There are four kinds of task dependencies in microsoft project : finish - to - start ( fs ) , in which a task cannot start until another task finishes ; start - to - start ( ss ) , in which a task cannot start until another task starts ; finish - to - finish ( ff ) , in which a task cannot finish until another task finishes ; and start - to - finish ( sf ) , in which a task cannot finish until another task starts 在microsoftproject中,有四种类型的任务相关性:完成-开始( fs ) ,在此类型中,某一任务完成后,另一项任务才能开始;开始-开始( ss ) ,在此类型中,某一任务开始后,才能开始另一项任务;完成-完成( ff ) ,在此类型中,某一任务完成后,才能完成另一项任务;开始-完成( sf ) ,在此类型中,某一任务开始后,才能完成另一项任务。
