【摘要】 随着社会经济的稳步增长,人们的生活水平得到了显著提高。然而,在这一进步的背后,食品安全问题却逐渐成为学术界关注的焦点。这一趋势进一步推动了冷链物流行业的蓬勃发展,并得到了社会各界的广泛关注。对冷链物流企业来说,尽管面临着巨大挑战,但也蕴含着前所未有的发展机遇。因此,对冷链物流企业的成本管理和碳排放管控进行精细化调整,对于提升企业的市场竞争力具有决定性影响。本文旨在通过运用系统动力学这一研究方法,剖析我国冷链物流企业在物流成本优化道路上的挑战,从而开辟出一条创新的研究路径和实用的方法论框架。这种研究方法不仅丰富了冷链物流领域的学术探索,而且积极推动了理论研究与实际操作的深度融合,为冷链物流企业的物流成本优化提供更系统、科学的指导,从而推动整个冷链物流行业可持续发展。本研究首先运用知识图谱与元分析技术,对冷链物流领域的核心词汇进行了深入的剖析和解读,结果表明,在降低物流企业成本方面,将仓储与配送环节进行联合优化相较于单独处理任一环节,具有更为显著的效果。本研究以冷链物流企业为核心对象,全面地考虑到企业在物流运作过程中的成本支出以及碳排放情况。本文采用系统动力学方法,构建了一个针对冷链物流企业物流成本的系统动力学模型。为了验证模型的实用性,本文选择以A冷链物流企业作为实际案例进行深入研究。在研究过程中,本文使用系统动力学仿真工具Vensim对模型进行有效的仿真分析和验证。通过深入剖析仿真结果,得到了导致物流成本及总碳排放量波动的核心因素,并提出了针对性改善策略。这些策略的目的是帮助企业有效地降低物流成本,提升整体企业运营效率,从而为冷链物流行业的可持续发展提供坚实支撑。根据本研究的结论,在冷链企业中由于配送费用、仓储费用、出入库费用等因素的不规则波动,使得整个物流成本发生了很大的变动。其中,配送成本的波动最为明显,对整个企业的物流成本起着决定性的作用。同时,研究也发现配送过程中碳排放量对总碳排放量的变动有显著影响。鉴于此,本研究提出以下策略以缓解上述问题:首先,通过提高配送车辆的装载率,优化运输效率,从而降低单位配送成本;其次,通过严格控制产品新鲜度和降低储存过程中的变质率,减少损耗,进而降低储存成本和出入库成本。这些策略的实施,有望对冷链物流企业的成本控制和碳排放管理产生积极影响。更多还原

【Abstract】 With steady socio-economic growth,people’s living standards have improved significantly.However,behind this progress,the issue of food safety has gradually become the focus of academic attention.This trend has further promoted the prosperous development of the cold chain logistics industry and has received extensive attention from all walks of life.For cold chain logistics enterprises,despite the great challenges,it also contains unprecedented development opportunities.Therefore,fine-tuning the cost management and carbon emission control of cold chain logistics enterprises has a decisive impact on improving their market competitiveness.This paper aims to analyse the challenges encountered by China’s cold chain logistics enterprises on the road of logistics cost optimisation by applying the research method of system dynamics,so as to open up an innovative research path and a practical methodological framework.This approach not only enriches the academic exploration in the field of cold chain logistics,but also actively promotes the in-depth integration of theoretical research and practical operation,and provides more systematic and scientific guidance for the optimisation of logistics costs of cold chain logistics enterprises,thus promoting the sustainable development of the entire cold chain logistics industry.This study first uses knowledge mapping and meta-analysis technology to deeply analyse and interpret the core vocabulary in the field of cold chain logistics,and the results show that in terms of reducing the cost of logistics enterprises,the joint optimization of warehousing and distribution links has a more significant effect than dealing with either link separately.This study takes cold chain logistics enterprises as the core object,and comprehensively considers the cost expenditure and carbon emission of enterprises in the logistics operation process.This paper adopts the system dynamics method to construct a system dynamics model for the logistics cost of cold chain logistics enterprises.In order to verify the practicality of the model,this paper chooses to take A cold chain logistics enterprise as an actual case for in-depth research.In the research process,this paper uses the system dynamics simulation tool Vensim to carry out effective simulation analysis and verification of the model.Through in-depth analysis of the simulation results,the core factors leading to fluctuations in logistics costs and total carbon emissions are obtained,and targeted improvement strategies are proposed.The purpose of these strategies is to help enterprises effectively reduce logistics costs and improve overall corporate operational efficiency,thus providing solid support for the sustainable development of the cold chain logistics industry.According to the conclusions of this study,the irregular fluctuations of distribution costs,warehousing costs,access costs and other factors in cold chain enterprises make the overall logistics costs undergo great changes.Among them,the fluctuation of distribution cost is the most obvious and plays a decisive role in the logistics cost of the whole enterprise.At the same time,the study also found that the carbon emissions in the distribution process have a significant impact on the variation of total carbon emissions.In view of this,this study proposes the following strategies to alleviate the above problems: firstly,optimise transport efficiency by increasing the loading rate of distribution vehicles,thereby reducing unit distribution costs;secondly,reduce losses by strictly controlling product freshness and reducing the deterioration rate in the storage process,thereby reducing storage costs and access costs.The implementation of these strategies is expected to have a positive impact on the cost control and carbon emission management of cold chain logistics enterprises.更多还原
