1、第11卷第4期交通運(yùn)輸工程學(xué)報(bào)Vol.11No.42011年8月JournalofTrafficandTransportationEngineeringAug.2011文章編號(hào):16711637(2011)04006808集裝箱船舶支線運(yùn)輸航線優(yōu)化算法計(jì)明軍,陳哲,王清斌(大連海事大學(xué)交通運(yùn)輸管理學(xué)院,遼寧大連116026)摘要:以樞紐港船舶限制時(shí)間和支線船舶容量為基礎(chǔ),分析了軸輻式網(wǎng)絡(luò)運(yùn)輸模式。以船舶最小總航行時(shí)間為目標(biāo)函數(shù),建立了混合整數(shù)規(guī)劃支線集裝箱運(yùn)輸模型。通過設(shè)計(jì)巡回路線方法實(shí)現(xiàn)雜交和變異,更新了解的構(gòu)成,運(yùn)用遺傳算法求解模型。計(jì)算結(jié)果表明:
2、當(dāng)船舶容量為150TEU時(shí),在160次迭代后,總航行時(shí)間為708.6h,航線數(shù)量為8條;當(dāng)船舶容量分別為100、150TEU時(shí),在150次迭代后,總航行時(shí)間為714.6h,航線數(shù)量為9條;對(duì)樞紐港船舶限制時(shí)間和支線船舶容量進(jìn)行方差分析,犉檢驗(yàn)統(tǒng)計(jì)量的概率值均明顯小于0.05;對(duì)支線船舶容量和運(yùn)營成本進(jìn)行敏感性分析,增大船舶容量能夠減小航線數(shù)量和運(yùn)行時(shí)間,但增大了運(yùn)營成本,增大樞紐港船舶限制時(shí)間能夠減小航線數(shù)量;考慮航行時(shí)間和運(yùn)營成本,當(dāng)船舶容量為150TEU時(shí)最合理。關(guān)鍵詞:集裝箱運(yùn)輸;航線設(shè)計(jì);軸輻式網(wǎng)絡(luò);整數(shù)規(guī)劃;遺傳算法;方差分析中圖分類號(hào):U692.
