某建设单位邀请A、B、C三家技术实力和资信俱佳的施工企业参加投标。招标文件中规定：评标时采用最低报价中标的原则，但最低投标价低于次低投标价10%的报价将不予考虑。工期不得大于16个月，若投标人自报工期少于18个月，在评标时将考虑其给建设单位带来的收益，折算成综合报价进行评标。
贷款月利率为1%，各分部工程每月完成的工作量相同，在评标时考虑工期提前给建设单位带来的收益为每月20万元。
三家投标单位投标书中与报价和工期有关的数据见表4.1。

Bush’s MBA

Twenty-six of 42 presidents, including Bill Clinton, were lawyers. Seven were generals. George W. Bush becomes the first with an MBA.
Those who have had Bush for a boss since the mid-1980s—in the (1) of oil, baseball and Texas state government—describe his management (2) as straight from the pages of the organizational-behavior (3) he studied while getting his masters of business administration (4) at Harvard University in 1975.
He manages by what is known (5) "walking around," having learned that sitting behind a desk and passing out memos does (6) to energize anyone.
He has a reputation for fueling "creative tension" (7) his subordinates, encouraging them to take and defend opposing (8) . That sacrifices harmony, but puts ideas to the test and lets Bush (9) above the fray, where he can offer guidance instead of barking (10) . Imagine the creative tension that may erupt (11) the likes of Secretary of State-designate Colin Powell and Defense Secretary— (12) Donald Rumsfeld.
Above all, former employees say that he is a master at delegating (13) installing measures of accountability—ways of knowing (14) subordinates are getting the job done without looking (15) any shoulders. That frees Bush for strategic thinking—perhaps (16) two words hammered into MBA students most—which means thinking (17) to seize opportunities and to derail threats to the best of plans.
"George was my (18) ," says Tom Schieffer, who served as president of the Texas Rangers under Bush (19) 1991 and 1995. "But he never made me feel that way. He went out of his way to treat me as a (20) , not a subordinate."
That’s one trait that might be of concern, says Michael Useem, director of the Wharton Center for Leadership and Change at the University of Pennsylvania. It’s important for subordinates to feel part of the team, but not just because the boss craves popularity. Just as in the military, it must be understood who is in charge when the final order is given.
