【摘要】：隨著人們生活水平和健康意識的提高,人們對食品是否新鮮,質(zhì)量能否得到保證的關(guān)注度也越來越高。冷鏈物流的誕生滿足了人們對食品質(zhì)量和新鮮度的要求。冷鏈物流的實質(zhì)是保證食品的質(zhì)量,具體操作就是將食品儲存在其所需的低溫環(huán)境中,直到產(chǎn)品到達消費者手中。冷鏈物流在我國的發(fā)展尚不成熟,冷鏈體系也不健全,所以對于冷鏈物流的研究是十分必要的。冷鏈物流中,當(dāng)屬冷鏈配送中心選址的研究最為關(guān)鍵,目前,我國對其理論研究尚不深入,因此,對于冷鏈物流配送中心選址的理論探討是十分必要的。另外,由于冷鏈配送中心連接著生產(chǎn)者與銷售者,如若冷鏈配送中心選址正確,就能降低物流成本、整合社會資源、減少交通壓力等。所以,無論從理論上還是現(xiàn)實利益上,冷鏈物流配送中心的選址研究都極其重要。本文首先詳細分析了該課題的研究背景,闡述了該課題研究的目的與意義,總結(jié)了國內(nèi)外冷鏈物流以及配送中心選址的相關(guān)理論研究。其次,探討了國內(nèi)外冷鏈物流的發(fā)展情況,重點分析了國內(nèi)冷鏈物流在發(fā)展過程中存在的問題,突出了課題研究的意義。然后,分析了冷鏈物流配送中心選址的相關(guān)影響因素,建立了評價指標(biāo)體系,提出了一種基于UEOWA和ULHA算子的多屬性決策方法來選擇候選配送中心地點。最后,根據(jù)第三方冷鏈物流的特點,建立了以總成本和服務(wù)水平最優(yōu)化的雙目標(biāo)選址模型。在模型求解過程中,運用懲罰成本這一概念對服務(wù)水平最大化目標(biāo)進行了轉(zhuǎn)化,得到了以成本最低的單目標(biāo)模型,并運用遺傳算法對模型進行求解,運用具體事例對其進行分析,證明了本論文中選址方法的可行性。本論文不僅運用定性與定量方法相結(jié)合的方式對冷鏈配送中心進行選址,而且利用總成本最低和服務(wù)水平最大化兩目標(biāo)建立數(shù)學(xué)模型,更加貼近現(xiàn)實情況,給企業(yè)進行配送中心選址提供了理論依據(jù)。
[Abstract]:With the improvement of people's living standard and health consciousness, people pay more and more attention to whether food is fresh or not. The birth of cold chain logistics meets the requirements of food quality and freshness. The essence of cold chain logistics is to ensure the quality of food. The concrete operation is to store the food in the low temperature environment it needs until the product reaches the consumer's hand. The development of cold chain logistics in our country is not mature, the cold chain system is not perfect, so the research on cold chain logistics is very necessary. In cold chain logistics, the research on the location of cold chain distribution center is the most important. At present, the theoretical research on the location of cold chain logistics distribution center is not in-depth. Therefore, it is very necessary to discuss the location theory of cold chain logistics distribution center. In addition, because the cold chain distribution center connects producers and sellers, if the location of cold chain distribution center is correct, it can reduce logistics cost, integrate social resources, reduce traffic pressure and so on. Therefore, it is very important to study the location of cold chain logistics distribution center in both theoretical and practical interests. Firstly, this paper analyzes the research background of this topic in detail, expounds the purpose and significance of the research, and summarizes the related theoretical research of cold chain logistics and distribution center location at home and abroad. Secondly, the development of cold chain logistics at home and abroad is discussed, and the problems existing in the development process of domestic cold chain logistics are emphatically analyzed, and the significance of the research is highlighted. Then, the related factors of cold chain logistics distribution center location are analyzed, the evaluation index system is established, and a multi-attribute decision-making method based on UEOWA and ULHA operator is proposed to select the candidate distribution center location. Finally, according to the characteristics of the third-party cold chain logistics, a two-objective location model based on the optimization of total cost and service level is established. In the process of solving the model, the goal of maximizing service level is transformed by using the concept of penalty cost, and a single objective model with the lowest cost is obtained, and the model is solved by genetic algorithm. The feasibility of the location selection method in this paper is proved by the analysis of concrete examples. This paper not only uses the combination of qualitative and quantitative methods to select the cold chain distribution center, but also establishes the mathematical model by using the goals of minimum total cost and maximum service level, which is closer to the reality. It provides a theoretical basis for the location of distribution center for enterprises.
