2、基礎(chǔ)指標(biāo)和發(fā)電設(shè)備的主要可靠性指標(biāo)基礎(chǔ)上，建立了火電廠各主要系統(tǒng)的可靠性評(píng)估模型。對(duì)發(fā)電企業(yè)的設(shè)備維修策略進(jìn)行了分析。建立了設(shè)備預(yù)防維修周期的優(yōu)化模型并用遺傳算法進(jìn)行了求解。然后對(duì)火電機(jī)組的可靠性評(píng)估和維修決策支持系統(tǒng)進(jìn)行了設(shè)計(jì)。最后對(duì)發(fā)電企業(yè)的設(shè)備可靠性評(píng)估和維修工作提出了展望。關(guān)鍵詞：可靠性評(píng)估模型維修策略遺傳算法ABSTI認(rèn)CTAlongwiththegradualdeepeningofcommercializedoperatio
