【摘要】 伴随着全球气候变化的影响,节能减排已成为业界共识。在此大背景下,低碳经济已经赢得了政府以及企业更多的关注。B2C电子商务以其便捷、经济以及高效性等优势成为近年来快速发展和普及的商务模式。由此也带动了作为商务交易环节重要支撑节点物流业的飞速发展。考虑到物流交通业是碳排放的一个重要来源,发展高效、节能、低成本的物流业不仅可以帮助企业降低运作成本提升企业的核心竞争力,同时也是践行企业社会责任感的重要体现。本文首先对现有物流选址-路径问题做了分析和总结,结合B2C模式下物流配送的新特点、新趋势以及低碳经济兴起的大背景,研究了低碳视角下的物流网络选址-路径问题,构建了集送一体配送模式下的低碳供应链模糊选址-路径模型。所做的工作如下:(1)对当前低碳化问题及选址-路径相关问题的研究进展进行梳理,并对当前低碳化物流以及选址-配送问题的研究现状及不足进行了总结,在此基础上提出了研究集送一体配送模式下的低碳供应链模糊选址-路径模型的重要意义。(2)模糊客户需求下的低碳供应链选址-路径模型构建。本文相关研究结合B2C商务模式下物流配送呈现的多批、少量以及个性化配送需求等特征,考虑到B2C环境下客户需求呈现出的波动性,对模糊客户需求下的低碳供应链选址-路径问题进行分析和研究,构建了集送一体配送模式下的低碳供应链模糊选址-路径模型。通过考虑配送实际以及客户需求的波动性以期为提升物流运营决策的可靠性,降低运营风险提供决策支持和参考。(3)智能启发式算法设计。针对所研究问题特点,考虑配送客户在空间距离以及期望服务时间差异性的基础上,引入时空距离的理念并设计了智能启发式算法为问题的求解提供新的视角。本文相关研究进一步丰富了低碳视角下物流配送网络选址-路径问题方面的研究,为低碳化物流运作提供了理论支撑。与此同时,本文所建立的集送一体物流配送模式下的低碳供应链模糊选址-路径优化模型结合了B2C商务模式下物流配送呈现出的少量、多批以及客户多样化配送需求等特征,为物流的运作决策提供了较强的参考价值。更多还原

【Abstract】 With the intensification of global warming,energy saving and emission reduction have become more and more important.The government and companies are paying more and more attention to the development of low-carbon economy.In recent years,B2 C e-commerce has become a fast-growing business model with the characteristics of convenience,economy and rapid response,which also led to the rapid development of the logistics industry.Considering that logistics transportation is one of the major sources of carbon emissions,the development of an efficient,energy-saving,low-cost logistics industry can not only help companies reduce operating costs but also an important manifestation of the social responsibility.This paper analyzes and summarizes the existing location-routing problem,and combines the new trends of logistics distribution under the B2 C model,and the background of the rise of low-carbon economy,proposes a location routing integration problem model under low-carbon perspective.The main work of this paper includes the following three aspects:(1)This paper reviews the current research progress,summarizes the current research status and shortcomings of low carbon logistics,and proposes the importance of studying low carbon location routing problem.(2)Establish a location-distribution model in low carbon supply chain under fuzzy demand.Combined with the characteristics in logistics distribution under the B2 C e-commerce mode,a location-distribution model in low carbon supply chain under fuzzy demand was constructed to improve the reliability of decision-making and reduce operational risk.(3)A heuristic algorithm was designed to solve the problem.According to the characteristics of model,a two stage heuristic algorithm was designed to solve the problem,taking into account the concept of space-time distance.The research in this paper further enriches the study on the location routing problem,and provides theoretical support for low-carbon logistics operation.The established model combines the distribution characteristics of B2 C business model,and provides a strong reference value for logistics management decisions.更多还原
