A new method on cost - forecast and optimizing decision - making is built up , aiming at nonlinear problem of fire - electric power set capital construction time limit cost , based on gray system theory 針對(duì)火電機(jī)組基建工期成本的非線性問(wèn)題,基于灰色系統(tǒng)理論,提出了一種成本預(yù)測(cè)與優(yōu)化決策的新方法。
It only took 38 months from construction preparation at the end of october , 2001 to the first unit operating on december 20 , 2004 , which antedated the construction time limit by 7 months 樂(lè)灘電站從2001年10月底開(kāi)始施工準(zhǔn)備到2004年12月20日首臺(tái)機(jī)組投產(chǎn)發(fā)電,僅用38個(gè)月的時(shí)間,比合理工期提前了7個(gè)月,并在此期間,搶回因廠壩部份地基巖溶地質(zhì)問(wèn)題延誤的5個(gè)月工期。
4 . relationship between simulation running times and construction time limit estimate precision is discussed , which solves the problem that how many running times are required in order to reach a certain construction time limit estimate precision 4 .探討了施工系統(tǒng)仿真運(yùn)行次數(shù)與施工工期估計(jì)精度之間的關(guān)系,解決了要達(dá)到某一施工工期估計(jì)精度所需仿真運(yùn)行次數(shù)的問(wèn)題。
