基于成本、可用性的串行生產(chǎn)系統(tǒng)維護(hù)策略研究
發(fā)布時(shí)間:2020-12-13 10:24
對(duì)于現(xiàn)代化的生產(chǎn)系統(tǒng)來(lái)說(shuō),預(yù)防性定期檢修起到了日漸重要的作用。此外,串行生產(chǎn)系統(tǒng)極易受到單一擾動(dòng)影響。實(shí)際上,一個(gè)故障或者計(jì)劃性檢修會(huì)導(dǎo)致無(wú)法避免的系統(tǒng)停運(yùn)。在系統(tǒng)停運(yùn)期間,部分元器件仍然處于冷備用狀態(tài),由停運(yùn)造成的生產(chǎn)損失也可折算成停運(yùn)成本。如果停運(yùn)是由系統(tǒng)元件強(qiáng)迫退出運(yùn)行造成的,則會(huì)進(jìn)行最小維修,以求在最短時(shí)間內(nèi)回復(fù)生產(chǎn)。同時(shí),通過(guò)系統(tǒng)模型可以預(yù)測(cè)到一部分的故障,基于故障預(yù)測(cè),可以執(zhí)行預(yù)防性的計(jì)劃?rùn)z修,以減小停運(yùn)時(shí)間。本文假設(shè)由設(shè)備老化以及外部原因?qū)е碌南到y(tǒng)故障近似服從韋伯分布。那么從系統(tǒng)成本以及可利用性角度出發(fā),可以生成一個(gè)全局性的維修策略。基于上述因素,本文提出了一個(gè)考慮最小成本和最大可利用率的全局目標(biāo)函數(shù)。其主要思想為,在由于一臺(tái)設(shè)備故障導(dǎo)致的系統(tǒng)停運(yùn)期間,可以同時(shí)進(jìn)行其他的設(shè)備計(jì)劃性檢修。本文提出了三個(gè)機(jī)會(huì)模型,分別獨(dú)立基于機(jī)會(huì)性檢修的時(shí)間窗定位,具體設(shè)備元件檢測(cè)定位,以及綜合考慮時(shí)間窗和設(shè)備定位。通過(guò)三個(gè)機(jī)會(huì)模型,從參數(shù)設(shè)置和計(jì)算成本上,本文詳細(xì)分析了計(jì)劃性維修策略優(yōu)化模型在串行系統(tǒng)中的具體應(yīng)用。相較于其他模型,本文提出的模型計(jì)算時(shí)間較長(zhǎng),但得到的最終故障損耗成本更低。
