For example , if two tasks can start at the same time , they are linked with a start - to - start dependency 譬如,如果兩個(gè)項(xiàng)目可以同時(shí)啟動(dòng),則鏈接為開始-開始( ss )相關(guān)性。
Tasks that have a start - to - start link and tasks with lead time are two kinds of tasks that can have overlap time 具有重疊時(shí)間的兩種任務(wù)是:具有開始-開始類型鏈接的任務(wù)、帶有前置重疊時(shí)間的任務(wù)。
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 不過,在鏈接任務(wù)后,可以將鏈接更改為開始-開始、結(jié)束-結(jié)束或開始-結(jié)束鏈接(也可以指定前置重疊時(shí)間和延隔時(shí)間) 。
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-開始( fs )鏈接的任務(wù)要比使用開始-開始( ss )鏈接或完成-完成( ff )鏈接的任務(wù)使項(xiàng)目工期增加的時(shí)間多。
* * * * 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 . 關(guān)于任務(wù)相關(guān)性的詳細(xì)情況,請(qǐng)參閱第5章“按恰當(dāng)?shù)捻樞蚝蜁r(shí)間完成任務(wù)” 。
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 有時(shí)重疊的時(shí)間非常多,結(jié)果是它們同時(shí)開始,如果這樣,請(qǐng)將fs鏈接改為開始-開始( ss )鏈接,而不是添加延隔時(shí)間。
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,有四種類型的任務(wù)相關(guān)性:完成-開始( fs ) ,在此類型中,某一任務(wù)完成后,另一項(xiàng)任務(wù)才能開始;開始-開始( ss ) ,在此類型中,某一任務(wù)開始后,才能開始另一項(xiàng)任務(wù);完成-完成( ff ) ,在此類型中,某一任務(wù)完成后,才能完成另一項(xiàng)任務(wù);開始-完成( sf ) ,在此類型中,某一任務(wù)開始后,才能完成另一項(xiàng)任務(wù)。
