T he life cycle cost w as set off acquisition cost an sustaining cost, the investment cost mo el base on timeproportion an the sustaining cost mo el base on Weibull istribution w ere built, the property of all parameters in Weibull istribution function w ere analyze , an the metho of getting the least cost an the best lifeperio w ere is cusse . Aiming the uncertainty in the sustaining cost mo el, the tw o parameters istribution simula tive metho of Weibull istribution are presente , an the relevant parameters by the metho of linear regression w ere estimate . In the en , the example of the parameters requeste is presente . Key words: hy roelectric equipment; life cycle cost; mo el; Weibull istribution , Llcc = Aac + Ssc , (1) . , : A ac ,
