Abstract: For fresh agricultural products distribution path optimization in the distribution cost unreasonable problems, in Urumqi north garden spring fresh agricultural products cold chain logistics distribution, for example, considering the carbon emissions, cargo loss and customer time window, build with comprehensive distribution cost minimization as the goal of fresh cold chain logistics distribution path optimization model and using genetic algorithm, comparative analysis does not consider carbon emissions and carbon emissions path planning, the analysis results show that considering the cost of carbon emissions, help to reduce carbon emissions, save distribution vehicle driving time, reduce the loss rate of fresh agricultural products, reduce the cost of comprehensive distribution. This paper can provide a theoretical basis for the optimization of urban fresh cold chain logistics distribution path.
Key words: path optimization; fresh agricultural products; genetic algorithm; carbon emission

" 隨著經(jīng)濟發(fā)展和消費水平的不斷升級,人們對生鮮農(nóng)產(chǎn)品品質(zhì)的要求不斷提高。生鮮農(nóng)產(chǎn)品具有保質(zhì)期短,易腐爛等不同于其他產(chǎn)品的特點,在運輸中需要制冷控制溫度,而這會導(dǎo)致碳排放增高,進(jìn)而增加成本,因此,通過路徑優(yōu)化來減少配送成本是城市生鮮冷鏈物流研究的重點之一。
對于生鮮食品物流配送路徑優(yōu)化問題,國內(nèi)外很多的學(xué)者從不同的方面對其進(jìn)行了研究。Wang et al[1]考慮客戶滿意度提出帶軟時間窗的生鮮配送路徑優(yōu)化模型。Agustina D et al[2]綜合考慮了生鮮農(nóng)產(chǎn)品的保質(zhì)期天數(shù)和交貨期限,構(gòu)建了帶有時間窗的車輛路徑問題的線性計劃交叉模型。方文婷等[3]以最小成本為目標(biāo)建立配送路徑優(yōu)化模型并使用蟻群算法進(jìn)行模型求解。張倩等[4]考慮產(chǎn)品新鮮程度、客戶需求量等因素建立配送路徑優(yōu)化模型,將果蠅算法用于模型求解。……
