计划完成预算
成本BCWS(元)
已完成工作
(%)
实际发生成本
ACWP(元)

B 308000 80 246800
C 230880 100 254034
D 280000 100 280000
9周末合计 1238880 1206034
[问题]
1.将上表复制到答题纸上,在表中计算前9周每项工作(即A、B、C、D各项工作)的BCWP。
2.计算9周末的费用偏差CV与进度偏差SV,并对结果含义加以说明。

答案

参考答案:1.计算如下表:

前9周成本统计
工作代号
计划完成预算
成本BCWS(元)
已完成工作
(%)
实际发生成本
ACWP(元)
已完成工作的预算
成本BCWP(元)
A 420000 100 425200 420000
B 308000 80 246800 246400
C 230880 100 254034 230880
D 280000 100 280000 280000
9周末合计 1238880 1206034 1177280
2.计算如下:
9周末的费用偏差CV=BCWP-ACWP=1177280-1206034=-28754元;
说明:因为CV为负,说明费用超支;
9周末的进度偏差SV=BCWP-BCWS=1177280-1238880=-61600元;
说明:因为SV为负,说明进度延误。

阅读下面的材料,然后根据材料内容回答所提问题。

     Once upon a time, there was an island. All the feelings lived there such as Happiness, Sadness, and Love.

One day the feelings heard that the island would sink (下沉). They all repaired their boats and left except Love.

Love wanted to stay until the last possible moment. Just as the island began to sink, Love decided to ask for

help.

     Miserliness (吝啬) was passing by Love in a big boat. Love said:"Miserliness, can you take me with you?"

Miserliness answered:"No, I can't. There are a lot of silver (银子) in my boat. There is no place for you here."

     Love decided to ask Vanity (虚荣) who was also passing by in a beautiful boat."Vanity, please help me!"

"I can't help you, Love. You are all wet. You'll make my boat dirty," Vanity said.

     Sadness was close by, so Love asked for help, "Sadness, let me go with you." "Oh…Love, I am so sad

that I need to be alone by myself!"

     Happiness passed by Love too, but she was so happy that she did not even hear Love call her.

     Suddenly, there was a voice, "Love, I will take you." It was an old woman. Love felt so lucky that he even

forgot to ask for her name. When they got to dry land, the old woman went away. Love asked Knowledge,

another old woman, "Who helped me?"

     "It was Time", Knowledge answered. "Time?" asked Love. "But why did Time help me?"

     Knowledge smiled with deep wisdom (智慧) and answered, "Because only Time can understand how great

Love is."
