一个项目由五个任务组成。 --任务A将需要五天时间才能完成,且可以立即开始。 --任务B将需要四天才能完成,但只能在任务A完成后才能开始。 --任务C将需要三天才能完成,并且在开始之前独立于任何其他任务。 --任务D将需要七天才能完成,但只能在任务C完成后才能开始。 --任务E将需要五天才能完成,但只能在任务B和D完成后才能开始。项目的关键路径是什么?
A project consists of five tasks. -Task A will take five days to complete and can begin immediately. -Task B will take four days to complete, but can begin only after task A has finishe -Task C will take three days to complete, and is independent of any other tasks before it can begin. -Task D will take seven days to complete, but can begin only after task C is finishe -Task E will take five days to complete, but can begin only after both tasks B and D have finishe What is the project's critical path ?
A.A—B—E
B.C—D—E
C.A—B—D—E
D.C—B—D—E
参考答案:B
解析:PMBOK(6)P210-6.5.2.2关键路径法。整个项目有两条路径,ABE,14天,CDE,15天,所以CDE是关键路径。
