【摘要】：随着社会的发展进步,广大消费者对高质量的生鲜农产品需求越来越多,这在一定程度上推动了冷链物流的快速发展。冷链物流的发展一方面带动了经济的快速发展,但同时对生态环境也产生一系列威胁,尤其近几年城市雾霾现象日益加重。鉴于此,在冷链物流配送过程中开始重视如何减少碳排放,这样不仅有利于提高配送质量和效率,还能够改善当前的环境现状,从而实现经济和环境效益的统一。本文首先阐述了冷链物流、车辆调度和碳排放的国内外研究现状以及现有研究中存在的问题,然后介绍了冷链物流、物流配送车辆调度、碳排放和常见的智能优化算法相关理论;其次,对生鲜农产品配送过程中的配送成本进行分析,主要考虑固定成本、运输成本、惩罚成本、制冷成本、货损成本和碳排放成本这六项成本,进而构建以总成本最小的生鲜农产品物流配送车辆调度模型;再次,根据构建的数学模型,阐述了相关的求解算法,设计改进的混合蚁群算法,结合美食林集团的案例,将算法应用到生鲜农产品物流配送车辆调度模型中,经过对比发现改进的混合蚁群算法能够得出更优解;最后,提出了生鲜农产品在配送过程中减少碳排放的对策与措施。
[Abstract]:With the development of society, the majority of consumers demand more and more fresh agricultural products of high quality. This has promoted the rapid development of cold chain logistics to a certain extent. On the one hand, the development of cold chain logistics has driven the rapid development of economy, but at the same time, it has also produced a series of threats to the ecological environment. Especially in recent years, the phenomenon of urban haze is becoming more and more serious. In view of this, in the cold chain logistics distribution process began to pay attention to how to reduce carbon emissions, which is not only conducive to improve the quality and efficiency of distribution. Also can improve the current environmental situation, so as to achieve the unity of economic and environmental benefits. Firstly, this paper describes the cold chain logistics, vehicle scheduling and carbon emissions at home and abroad research status and existing problems. Then introduces the cold chain logistics, logistics distribution vehicle scheduling, carbon emissions and common intelligent optimization algorithms related to the theory; Secondly, the distribution costs of fresh agricultural products are analyzed, including fixed cost, transportation cost, penalty cost, refrigeration cost, damage cost and carbon emission cost. Then build the vehicle scheduling model of fresh agricultural products logistics distribution with the minimum total cost; Thirdly, according to the mathematical model, this paper expounds the related algorithm, designs the improved hybrid ant colony algorithm, and applies the algorithm to the vehicle scheduling model of fresh agricultural products logistics distribution combined with the case of Gourmet Forest Group. It is found that the improved hybrid ant colony algorithm can get a better solution. Finally, the countermeasures and measures of reducing carbon emission in the distribution of fresh agricultural products are put forward.
