单项选择题
The expected time TE used in the PERT algorithm is calculated using the following equation ______.
A) (a+3m+b)/6
B) (a+4m+b))/6
C) (a+5m+b)/6
D) (a+m+b)/3
Note: A major assumption for all network methods is that activity durations are statistically dependent and where a=most optimistic time, b=most pessimistic time, m=most likely time.
答案
参考答案:B
解析:在PERT算法中使用的期望时间TE使用______计算。
A) (a+3m+b)/6
B) (a+4m+b))/6
C) (a+5m+b)/6
D) (a+m+b)/3
注意:所有网络方法的一个主要假设是所有活动周期在统计上是互相依赖的,
其中,a=最乐观时间,b=最悲观时间,m=最可能时间。
