【摘要】：冷鏈物流在人們的日常生活中發(fā)揮著重要作用。隨著我國(guó)國(guó)民經(jīng)濟(jì)的飛速發(fā)展,人民生活水平不斷的提高。與此同時(shí),伴隨著人們對(duì)生活品質(zhì)的追求以及對(duì)食品安全的關(guān)注也越來(lái)越高。農(nóng)產(chǎn)品是人類(lèi)一日三餐的原材料,具有需求大、易變質(zhì)、冷藏保鮮的特點(diǎn),這使得農(nóng)產(chǎn)品冷鏈配送成本高昂。因此,對(duì)農(nóng)產(chǎn)品冷鏈物流配送路徑優(yōu)化進(jìn)行研究,能夠加快農(nóng)產(chǎn)品的銷(xiāo)售和流通,降低配送成本,提高企業(yè)效益和客戶(hù)效用,推動(dòng)冷鏈物流的快速發(fā)展。首先,本文對(duì)農(nóng)產(chǎn)品冷鏈物流基礎(chǔ)理論和車(chē)輛路徑問(wèn)題基礎(chǔ)理論進(jìn)行了介紹,對(duì)農(nóng)產(chǎn)品冷鏈物流及冷鏈配送的概念、分類(lèi)、冷鏈配送的特點(diǎn)、車(chē)輛路徑優(yōu)化算法進(jìn)行闡述,為后文農(nóng)產(chǎn)品冷鏈配送路徑優(yōu)化模型的構(gòu)建及求解奠定理論基礎(chǔ)。其次,對(duì)農(nóng)產(chǎn)品冷鏈配送成本進(jìn)行分析,綜合考慮客戶(hù)服務(wù)時(shí)間窗約束、車(chē)輛容量約束、客戶(hù)滿(mǎn)意度約束,以總成本最小為目標(biāo),構(gòu)建了含補(bǔ)償機(jī)制的農(nóng)產(chǎn)品冷鏈配送路徑優(yōu)化模型。然后,以美食林公司配送中心的冷卻肉配送為例,獲取相關(guān)數(shù)據(jù),帶入本文所建立的農(nóng)產(chǎn)品冷鏈配送路徑優(yōu)化模型,并用改進(jìn)的蟻群算法進(jìn)行求解,得到了總成本最小的最佳配送路徑。最后,針對(duì)美食林公司冷卻肉配送中遇到的問(wèn)題,給出了提高該公司配送中心冷鏈配送效率的對(duì)策與措施。
[Abstract]:Cold chain logistics plays an important role in people's daily life. With the rapid development of our national economy, people's living standards are constantly improving. Along with people's pursuit of quality of life and the concern for food safety, agricultural products are the raw materials for three meals a day, which have the characteristics of large demand, easy to deteriorate and keep fresh in cold storage. This makes the cold chain distribution of agricultural products high cost. Therefore, the research on the distribution path optimization of cold chain logistics of agricultural products can speed up the sale and circulation of agricultural products, reduce the distribution costs, improve the efficiency of enterprises and customer utility. Promote the rapid development of cold-chain logistics. Firstly, this paper introduces the basic theory of cold-chain logistics of agricultural products and the basic theory of vehicle routing problem, and classifies the concepts of cold-chain logistics and cold-chain distribution of agricultural products. The characteristics of cold-chain distribution, vehicle routing optimization algorithm is elaborated, which lays a theoretical foundation for the construction and solution of cold-chain distribution path optimization model for agricultural products. Secondly, the cost of cold-chain distribution of agricultural products is analyzed. Considering the constraints of customer service time window, vehicle capacity and customer satisfaction, a cold chain distribution path optimization model of agricultural products with compensation mechanism is constructed, aiming at the minimum total cost. Take the cooling meat distribution in the distribution center of the food forest company as an example, obtain the relevant data, bring into the cold-chain distribution path optimization model of agricultural products established in this paper, and use the improved ant colony algorithm to solve the problem. The optimal distribution path with the lowest total cost was obtained. Finally, the countermeasures and measures to improve the efficiency of cold chain distribution in the distribution center of the food forest company were put forward in view of the problems encountered in the distribution of cooling meat in the food forest company.
