问题 问答题 案例分析题

【背景材料】某工程项目设计人员根据业主的使用要求,提出了3个设计方案。有关专家决定从5个方面(分别以F1~F5表示)对不同方案的功能进行评价,并对各功能的重要性分析如下:F3相对于F4很重要,F3相对于F1较重要,F2和F5同样重要,F4和F5同样重要。各方案单位面积造价及专家对3个方案满足程度的评分结果见表4-33。

试用0-4评分法计算各功能的权重(填入表4-34)。

答案

参考答案:

各功能权重的计算见表4-37。

解析:

考查利用0-4评分法进行价值工程分析。

1.利用0-4评分法进行功能权重的计算时,主要是将其各功能的分值确定准确。

F3相对于F4很重要,则F3得4分,F4得0分;

F3相对于F1较重要,则F3得3分,F1得1分;

F2和F5同样重要,则F2得2分,F5得2分;

F4和F5同样重要,则F4得2分,F5得2分。

由以上可知,F1相对于F2和F5也很重要,则F3得4分,F2和F5得0分;F1相对于F2、F4和F5重要,则F1得3分,F2、F4和F5得1分。

2.功能目标成本=建安工程目标成本×功能指数。

3.应降低额=目前成本-目标成本。

     Raising pets is a popular online game among reenagers. " More than 20 of my classmates have

adopted (领养) pets online, while last year the number was just 10," said Wang Hui, a middle school

student from Beijing, who also raises pets online.

     If you go to some websites,  you can adopt virtual (虚拟的) pets like penguins, chickens, dogs and

elephants. You can feed, wash, talk to and play with your pet.

     Dai Yingshuang of Shanghai raises pets on Kaixin001. com. The 15-year-old said it is great fun. She

thinks that she has "also learned how to take care of others".

     If one doesn't feed and care for the pet, it becomes unhappy and unhealthy.  So raising an online pet

means spending a lot of time online.

     This makes many parents worried. They fear there will be bad influence on the children's studies.

     Dai said that she usually asks her uncle to take care of her pet, while she is at school.

     Wang Zhaotong, from Anhui, has been raising a penguin on QQ.com since last year. The 14-year-old

takes good care of the penguin.

pets online.
