【摘要】：隨著經(jīng)濟的飛速發(fā)展,互聯(lián)網(wǎng)絡的發(fā)展也開始逐步趨向于成熟,網(wǎng)絡購物已經(jīng)開始成為人們?nèi)粘Ｉ钪胁豢苫蛉钡囊徊糠?國內(nèi)電子商務借此獲得了飛速發(fā)展。近些年來,我國的電子商務各項交易增長量一直保持著較快的發(fā)展勢頭。在電子商務飛速發(fā)展的形勢下,生鮮產(chǎn)品電子商務應運而生,生鮮產(chǎn)品電子商務發(fā)展迅速,市場規(guī)模巨大,但是,到目前為止,僅僅依靠生鮮產(chǎn)品電子商務開啟盈利模式的電商近乎沒有,究其原因,一是因為生鮮電商以生鮮產(chǎn)品的訂單作為賴以生存的源泉,二是因為生鮮產(chǎn)品對于產(chǎn)品新鮮度與時間有著較高的要求,大多采用冷鏈配送,冷鏈配送比一般的物流產(chǎn)品配送要求更高也更復雜,前期需要投入大量的資金,三是因為生鮮產(chǎn)品相對于其他的產(chǎn)品來說,生鮮產(chǎn)品更容易損壞,必須使用特定的包裝對其進行加護,還需配備特定的外部包裝加以輔助。本文著重考慮物流配送過程中的準時制及貨損因素,構(gòu)建生鮮產(chǎn)品物流配送路徑優(yōu)化模型,以期在達到降低總成本的基礎上,進一步確保生鮮產(chǎn)品的配送過程可以在準時、貨損較小、效率較高的情況下完成。論文首先對電子商務環(huán)境下生鮮產(chǎn)品的概念進行相關(guān)論述,然后對生鮮產(chǎn)品的物流配送系統(tǒng)進行分析,接著對生鮮產(chǎn)品在物流配送環(huán)節(jié)中的主要模式進行闡述,指出生鮮產(chǎn)品在物流配送環(huán)節(jié)中的不足之處。對生鮮產(chǎn)品物流配送過程中路徑優(yōu)化所需要考慮的準時制、貨損等因素進行相關(guān)研究,建立起一個總成本最低、充分保證生鮮產(chǎn)品的新鮮度、準時性以及貨損較小的生鮮產(chǎn)品物流配送路徑優(yōu)化模型。最后以天津市某生鮮企業(yè)為實例,對相關(guān)數(shù)據(jù)進行分析,利用遺傳算法進行求解,從而求得天津市某生鮮企業(yè)物流配送路徑優(yōu)化后,最低成本和最優(yōu)的車輛調(diào)度方案。優(yōu)化后的天津市某生鮮企業(yè)生鮮產(chǎn)品配送方案與原配送方案相比,行駛距離減少,生鮮產(chǎn)品配送過程中的成本降低,配送車輛減少,固定成本降低,準時性大大提高,同時因為沒有準時到達而產(chǎn)生的懲罰成本也降低了。另一方面,經(jīng)過優(yōu)化后的配送方案配送效率提高,配送過程中的利潤隨之提高。優(yōu)化后的相關(guān)結(jié)果顯示了所建立的模型及所利用的算法的有效性。
[Abstract]:With the rapid development of economy, the development of the Internet has gradually tended to mature, online shopping has begun to become an indispensable part of people's daily life, and domestic e-commerce has gained rapid development. In recent years, China's e-commerce transactions have maintained a rapid growth momentum. Under the situation of the rapid development of electronic commerce, the e-commerce of fresh products emerges as the times require, the electronic commerce of fresh products develops rapidly, and the market scale is huge. However, so far, There are almost no e-commerce businesses that rely solely on e-commerce to open the profit model of fresh products. One reason is that they rely on orders for fresh products as the source of their survival. Second, because fresh products have higher requirements for product freshness and time, most of them use cold chain distribution. Cold chain distribution requires higher and more complex distribution requirements than general logistics products, and a large amount of capital needs to be invested in the early stage. The third reason is that fresh products are more easily damaged than other products, they must be added and protected by special packaging, and need to be supplemented by special external packaging. This paper focuses on the punctual system and the damage factors in the process of logistics distribution, and constructs the optimization model of logistics distribution path of fresh products, in order to further ensure that the distribution process of fresh products can be on time on the basis of reducing the total cost. The damage is smaller and more efficient in the case of completion. The paper firstly discusses the concept of fresh product in electronic commerce environment, then analyzes the logistics distribution system of fresh product, and then expounds the main mode of fresh product in logistics distribution. The deficiency of fresh product in logistics distribution is pointed out. In order to establish the lowest total cost and ensure the freshness of fresh products, the just-in-time, damage and other factors that need to be considered in the process of route optimization of fresh products are studied in order to ensure the freshness of fresh products. The logistics distribution route optimization model of fresh products with punctuality and less damage. Finally, taking a fresh enterprise in Tianjin as an example, the relevant data are analyzed and solved by genetic algorithm, so as to obtain the lowest cost and the optimal vehicle scheduling scheme after the logistics distribution route optimization of a fresh enterprise in Tianjin. Compared with the original distribution scheme, the optimized fresh product distribution scheme of a Tianjin fresh enterprise reduces the driving distance, reduces the cost in the distribution process of fresh product, reduces the distribution vehicle, reduces the fixed cost, and improves the punctuality greatly. The cost of punishment for not arriving on time has also been reduced. On the other hand, the efficiency of the optimized distribution scheme is improved, and the profit in the distribution process increases. The optimized results show the effectiveness of the proposed model and the algorithm.
