　　負(fù)載裝卸（The Load Haul Dump,LHD）設(shè)備及其操作環(huán)境是采礦業(yè)中比較復(fù)雜的問(wèn)題。采礦生產(chǎn)率取決于LHD的操作和采礦環(huán)境,包括破碎度,礫石尺寸,導(dǎo)航技術(shù)等。確保采礦設(shè)備的有效性是采礦業(yè)面臨的一項(xiàng)巨大挑戰(zhàn),它影響著礦業(yè)公司在全球采礦業(yè)的競(jìng)爭(zhēng)優(yōu)勢(shì)。傳統(tǒng)的導(dǎo)航技術(shù)需要大量的基礎(chǔ)設(shè)施來(lái)適應(yīng)自動(dòng)操作。從全自動(dòng)車隊(duì)開(kāi)始,自動(dòng)化的范圍逐漸擴(kuò)大,包括更靈活的解決方案,如以安全為主要目標(biāo)的半自動(dòng)LHD機(jī)器等。因此,對(duì)于采礦業(yè)來(lái)說(shuō),利用其集約化設(shè)備進(jìn)行適當(dāng)?shù)臏y(cè)量是非常重要的。為了使自動(dòng)化的好處最大化,必須解決以下幾個(gè)問(wèn)題。一是改進(jìn)維護(hù)策略,特別是預(yù)防性維護(hù),因?yàn)檫@對(duì)于避免意外故障造成的時(shí)間損失至關(guān)重要。另一個(gè)問(wèn)題是采礦環(huán)境的復(fù)雜性,外部干擾,如超大巨石、道路維護(hù)等,這可能會(huì)使整個(gè)自動(dòng)化的投入受到挑戰(zhàn)。本文旨在開(kāi)發(fā)一種使用R-studio軟件的算法,該算法將科學(xué)地用于確定和評(píng)估采礦設(shè)備的生命周期,并確定和分析整體設(shè)備有效性（the Overall Equipment Effectiveness,OEE）以評(píng)價(jià)采礦設(shè)備,并確保優(yōu)化過(guò)程的有效性。研究方法包括文獻(xiàn)綜述、非結(jié)構(gòu)化訪談以及數(shù)據(jù)收集等方...
