1、第23卷第9期中國(guó)礦業(yè)Vo1．23，No．92014年9月CHINAMININGMAGAZINESep．2014基于統(tǒng)計(jì)模糊權(quán)重和模糊區(qū)間評(píng)價(jià)的采礦方法優(yōu)選模型姚囝，葉義成，王其虎，施耀斌，魯方(武漢科技大學(xué)資源與環(huán)境工程學(xué)院，湖北武漢430081)摘要：針對(duì)采礦方法優(yōu)選過(guò)程中評(píng)價(jià)指標(biāo)及其權(quán)重值較難確定的問(wèn)題，提出了基于統(tǒng)計(jì)方法的指標(biāo)權(quán)重值計(jì)算方法。通過(guò)對(duì)大量采礦方法優(yōu)選學(xué)術(shù)論文的統(tǒng)計(jì)和分析，綜合分析了大量采礦行業(yè)專家在采礦方法優(yōu)選過(guò)程中評(píng)價(jià)指標(biāo)模型，確定了以基于被選次數(shù)統(tǒng)計(jì)的指標(biāo)權(quán)重值和帶權(quán)重統(tǒng)計(jì)的指標(biāo)權(quán)重值為區(qū)間邊界、二者綜合計(jì)算的加權(quán)指標(biāo)權(quán)重值為最大可能值的評(píng)價(jià)指標(biāo)模糊區(qū)問(wèn)權(quán)重值。根
2、據(jù)模糊評(píng)價(jià)原理建立了模糊區(qū)間評(píng)價(jià)模型，建立了一種計(jì)算簡(jiǎn)便的區(qū)間數(shù)概率密度函數(shù)，并設(shè)計(jì)了一種區(qū)間數(shù)排序方法，利用模糊區(qū)間評(píng)價(jià)方法對(duì)評(píng)價(jià)方案進(jìn)行了最大可能值排序和區(qū)間數(shù)排序，并綜合考慮兩種排序結(jié)果確定了最終排序。采用基于統(tǒng)計(jì)模糊權(quán)重和模糊區(qū)間評(píng)價(jià)的采礦方法優(yōu)選模型進(jìn)行了某多層礦床采礦方法優(yōu)選，應(yīng)用案例表明，用模糊區(qū)間數(shù)表示評(píng)價(jià)指標(biāo)權(quán)重值更加準(zhǔn)確、合理，評(píng)價(jià)過(guò)程較好地模擬了優(yōu)選過(guò)程中的模糊性和不確定性，對(duì)采礦方法優(yōu)選具有一定參考意義。關(guān)鍵詞：采礦方法；優(yōu)選；評(píng)價(jià)指標(biāo)；統(tǒng)計(jì)方法；模糊區(qū)間權(quán)重值；模糊區(qū)間評(píng)價(jià)中圖分類號(hào)：TD823文獻(xiàn)標(biāo)識(shí)碼：A文章編號(hào)：1004—4051(2014)09—0112—
