1、合肥工業(yè)大學(xué)碩士學(xué)位論文基于蟻群算法的倉庫揀貨路徑優(yōu)化研究姓名:雷娟娟申請學(xué)位級別:碩士專業(yè):企業(yè)管理及其信息化指導(dǎo)教師:李興國20100401基于蟻群算法的倉庫揀貨路徑優(yōu)化研究摘要越來越多的企業(yè)構(gòu)建自己的倉庫和配送體系,以期降低物流成本,保持自己的競爭力。物流作為“第三利潤源泉"越來越受重視?,F(xiàn)代倉庫是物流不可或缺的一部分,揀貨作業(yè)是倉庫的核心作業(yè)環(huán)節(jié),揀貨成本占到整個倉庫物流成本的40%,其效率的高低直接影響到整個倉庫的效率,而提高揀貨作業(yè)效率,縮短揀貨路徑長度至關(guān)重要。本文選擇雙區(qū)型倉庫為
2、研究對象,應(yīng)用蟻群算法對揀貨路徑加以優(yōu)化。本文首先分析了倉庫揀貨路徑的研究現(xiàn)狀和存在的問題,綜述了物流揀貨路徑的相關(guān)問題,包括揀貨作業(yè)流程、倉庫中典型的雙區(qū)型倉庫和影響揀貨的因素等。其次根據(jù)雙區(qū)型倉庫中揀貨路徑問題的特點(diǎn),將該問題分成不考慮揀貨車輛容積和考慮揀貨車容積兩種情況,針對不考慮揀貨車容積的情況,采用蟻群算法優(yōu)化求解其揀貨路徑問題,并將該算法的結(jié)果與S形啟發(fā)式算法進(jìn)行比較,驗證了該方法的有效性。最后針對考慮揀貨車容積的情況,應(yīng)用蟻群算法對揀貨路徑問題進(jìn)行建模求解,并在VsiualC++6
3、.0平臺上上實現(xiàn)了該算法,與遺傳算法的優(yōu)化結(jié)果進(jìn)行比較發(fā)現(xiàn)當(dāng)揀貨數(shù)量較多時,該算法具有明顯優(yōu)勢。關(guān)鍵詞:蟻群算法;雙區(qū)型倉庫;揀貨路徑ResearchonOptimizationmethodofpickingroutinginthewarehouseBasedonAntColonyAlgorithmABSTRACTMoreandmorecompaniesbuildwarehouseanddistributionsystem.Theywanttoreducelogisticscostandmain
