问题:

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。在基本确定了技术方案后,为提高竞争能力,对其中某技术措施拟定了3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3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6-1。
假定所有关键工作压缩后不改变关键线路。

     When Mary Moore began her high school in 1951, her mother told her, "Be sure and take a typing

course so when this show business thing doesn't work out, you'll have something to rely on." Mary

responded in typical teenage fashion. From that moment on, "the very last thing I ever thought about

doing was taking a typing course," she recalls.

    The show business thing worked out, of course. In her career, Mary won many awards. Only recently, when she began to write Growing Up Again, did she regret ignoring her morn," I don't know how to use

a computer," she admits.

    Unlike her 1995 autobiography, After All, her second book is less about life as an

award-winning actress and more about living with diabetes (糖尿病). All the money from the book is

intended for the Juvenile Diabetes Research Foundation (JDRF), an organization she serves as

international chairman. "I felt there was a need for a book like this," she says."I didn't want to lecture, but

I wanted other diabetics to know that things get better when we're self-controlled and do our part in

managing the disease."

    But she hasn't always practiced what she teaches. In her book, she describes that awful day, almost

40 years ago, when she received two pieces of life-changing news. First, she had lost the baby she was

carrying, and second, tests showed that she had diabetes. In a childlike act, she left the hospital and

treated herself to a box of doughnuts (甜甜圈). Years would pass before she realized she had to grow

up-again-and take control of her diabetes, not let it control her. Only then did she kick her

three-pack-a-day cigarette habit, overcome her addiction to alcohol, and begin to follow a balanced diet.

    Although her disease has affected her eyesight and forced her to the sidelines of the dance floor, she

refuses to fall into self-pity. "Everybody on earth can ask, 'why me?' about something or other," she

insists. "It doesn't do any good. No one is immune (免疫的) to heartache, pain, and disappointments.

Sometimes we can make things better by helping others. I've come to realize the importance of that as

I've grown up this second time. I want to speak out and be as helpful as I can be."
