题目:

某工程,业主在招标文件中规定:工期T(周)不得超过80周,也不应短于60周。
某施工单位决定参与该工程的投标。在基本确定技术方案后,为提高竞争能力,对其中某技术措施拟定了三个方案进行比选。方案一的费用为C1=100+4T;方案二的费用为C2=150+3T;方案三的费用为C3=250+2T。
这种技术措施的三个比选方案对施工网络计划的关键线路均没有影响。各关键工作可压缩的时间及相应增加的费用见表7-1。
表7-1关键工作可压缩数据表

关键工作 A C E H M
可压缩时间(周) 1 2 1 3 2
压缩单位时间增加的费用(万元/周) 3.5 2.5 4.5 6.0 2.0
假定所有关键工作压缩后不改变关键线路。
[问题]1.该施工单位应采用哪种技术措施方案投标为什么
2.该工程采用问题1中选用的技术措施方案时的工期为80周,造价为2653万元。为了争取中标,该施工单位投标应报工期和报价各为多少
3.若招标文件规定,施工单位自报工期小于80周时,工期每提前1周,其总报价降低2万元作为经评审的报价,则施工单位的自报工期应为多少相应的经评审的报价为多少
4.如果该工程的施工网络计划如图7-1所示,则压缩哪些关键工作可能改变关键线路压缩哪些关键工作不会改变关键线路

Have you ever picked a job based on the fact that you were good at it but later found it made you feel very uncomfortable over time? When you select your career, there’s a whole lot more to it than assessing your skills and matching them with a particular position. If you ignore your personality, it will hurt you long-term regardless of your skills or the job’s pay. There are several areas of your personality that you need to consider to help you find a good job. Here are a few of those main areas:

Do you prefer working alone or with other people? There are isolating(使孤立)jobs that will drive an outgoing person crazy and also interactive jobs that will make a shy person uneasy. Most people are not extremes in either direction but do have a tendency that they prefer. There are also positions that are sometimes a combination of the two, which may be best for someone in the middle who adapts easily to either situation.

How do you handle change? Most jobs these days have some elements of change to them, but some are more than others. If you need stability in your life, you may need a job where the changes don’t happen so often. Other people would be bored of the same daily routine.

Do you enjoy working with computers? I do see this as a kind of personality characteristic. There are people who are happy to spend more than 40 hours a week on a computer, while there are others who need a lot of human interaction throughout the day. Again, these are extremes and you’ll likely find a lot of positions somewhere in the middle as well.

________________________________? This can range from being in a large building with a lot of people you won’t know immediately to a smaller setting where you’ll get to know almost all the people there fairly quickly.

How do you like to get paid? Some people are motivated by the pay they get, while others feel too stressed to be like that. The variety of payment designs in the sales industry is a typical example for this.

Anyway, these are a great starting point for you. I’ve seen it over and over again with people that they make more money over time when they do something they love. It may take you a little longer, but making a move to do what you have a passion for can change the course of your life for the better.
