【摘要】：进入新世纪以来,我国储藏保鲜技术的迅速发展,冷链物流的发展环境和基础设施条件不断改善,使冷链物流得到较快发展。我国冷链物流发展现正处于起步阶段,受制于冷链物流基础设施能力、物流技术、法律法规等因素,冷链物流运输效率低下、腐损率高、成本高,一体化的冷链物流体系有待形成。如何在既有条件下,提高冷链物流的流通率,降低流通过程中的腐损率和物流成本,是现阶段发展冷链物流所面临的最直接问题。首先,总结冷链物流运输组织的国内外研究现状,确定研究技术路线,并梳理冷链物流运输组织的基本概念,对初级农产品、加工食品、特殊商品等不同冷链产品的特点、运输组织流程进行对比分析。其次,结合冷链物流可以采用的运输组织模式,分析四种运输方式、产品在途损失、时间限制等因素对其的影响,构建冷链物流运输组织模式优化模型,并运用禁忌搜索算法进行求解。最后,以农产品中的蔬菜为例,构建具体算例,对所建立的优化模型进行应用,并对结果进行分析,以算例结果验证所建模型的合理性及算法的有效性。本文从冷链物流运输组织方式组合选择的角度展开研究,阐述相关理论,构建优化模型,寻求合理且优化的冷链物流运输组织模式,以期为提高冷链流通率、降低冷链腐损率、降低冷链成本提供途径和参考。
[Abstract]:Since entering the new century , the rapid development of storage and fresh - keeping technology in our country , the development environment of cold - chain logistics and the improvement of infrastructure conditions have made the cold - chain logistics develop rapidly . The cold - chain logistics system is still in the initial stage . The cold - chain logistics system needs to be formed under the conditions of cold chain logistics infrastructure capability , logistics technology , laws and regulations , etc . How to improve the circulation rate of cold chain logistics under the existing conditions , reduce the corrosion rate and logistics cost in the circulation process , and is the most direct problem to develop cold chain logistics at present . Firstly , the research status of cold chain logistics transportation organization is summarized , the research technology route is determined , the basic concept of cold chain logistics transportation organization is analyzed , and the characteristics of different cold chain products such as primary agricultural products , processed foods and special commodities are analyzed and analyzed . Secondly , based on the transportation organization model which can be adopted in the cold chain logistics , the influence of four modes of transportation , the loss of the product , the time limit and so on are analyzed , and the cold chain logistics transportation organization pattern optimization model is constructed and solved by using the tabu search algorithm . Finally , taking the vegetable in the agricultural product as an example , the concrete example is constructed , the established optimization model is applied , and the result is analyzed , and the rationality of the model and the validity of the algorithm are verified by the example result . In this paper , the research is carried out from the angle of combination selection of cold chain logistics transportation organization mode , the relevant theory is explained , the optimization model is constructed , the reasonable and optimized cold chain logistics transportation organization mode is sought , so as to improve the flow rate of the cold chain , reduce the corrosion rate of the cold chain and reduce the cold chain cost .
