【摘要】：寄售库存是供应链环境下的一种联合库存管理理论,它指供应商在使用货物前暂不取得货物及其所有权,而是将其存放于生产商仓库中,直至使用后才支付相关费用。在实践中越来越多的企业开始运用寄售库存策略,并取得了很好的效果。目前对它的研究仍有待深入,绝大部分也并没有考虑运输成本这一问题。根据物流系统中的效益背反理论,库存控制和运输决策都是配送供应链系统的一部分,整体研究应优于分别研究。而供应链管理的最终目标是使整个系统效益的最优化。事实表明,库存及运输费用的总和可以通过优化算法得到显著的降低。怎样通过优化理论实现库存及运输问题的整体最优成为了学术界的热点,计算机科学、运筹学、管理科学与工程、系统理论等领域的学者们已经开始了对该问题的研究。本文对考虑轴辐式网络的单卖方多买方寄售库存模型进行了研究。文章对联合生产库存、寄售库存、轴辐式网络和库存运输集成的相关文献进行了综述研究。并分析了现有寄售库存模型的不足,结合轴辐式网络理论,针对Zavanella和Zanoni的模型,本文构建了一个单卖方多买方的寄售库存模型(CS Model),相较了前者更全面严谨,更符合实际情况,并细化了运输成本变量,分别构建了全连通运输的寄售库存模型和轴辐式运输寄售库存模型,并用遗传算法进行了算例仿真,分别比较了买方和卖方的库存成本和运输成本。实验结果表明,相较于点对点运输的全连通网络,具有干线运输折扣的轴辐式网络是更有利于降低系统总成本的运输网络。但是在不同的折扣参数下,应选用不同的运输策略。最后,总结了本文所做的工作,指出了文中仍存在的问题,并且对未来可继续研究的方向做了展望。
[Abstract]:Consignment inventory is a kind of joint inventory management theory in the supply chain environment. It refers to the supplier does not acquire the goods and their ownership before using the goods, but stores them in the warehouse of the manufacturer, and pays the related expenses only after using them.In practice, more and more enterprises began to use consignment inventory strategy, and achieved good results.At present, the research on it is still to be deepened, and most of them do not consider the transportation cost.According to the inverse theory of benefit in logistics system, inventory control and transportation decision are both part of the distribution supply chain system, so the overall research should be better than the separate research.The ultimate goal of supply chain management is to optimize the benefit of the whole system.It is shown that the sum of inventory and transportation costs can be significantly reduced by the optimization algorithm.How to realize the overall optimization of inventory and transportation through optimization theory has become a hot topic in academic circles. Scholars in the fields of computer science, operational research, management science and engineering, system theory and so on have begun to study this problem.In this paper, a single seller multi-buyer consignment inventory model considering radial network is studied.In this paper, the related literatures on joint production inventory, consignment inventory, axle radial network and inventory transportation integration are reviewed and studied.This paper also analyzes the deficiency of the existing consignment inventory model, combined with the axle-spoke network theory, aiming at the models of Zavanella and Zanoni, this paper constructs a single seller and multi-buyer consignment inventory model, which is more comprehensive and rigorous than the former, and more in line with the actual situation.The transportation cost variables are refined, the consignment inventory model of fully connected transportation and the spool transport consignment inventory model are constructed, and the genetic algorithm is used to simulate the inventory cost and transportation cost of buyer and seller respectively.The experimental results show that the axis-radial network with trunk line transportation discount is more favorable to reduce the total cost of the system than the point-to-point fully connected network.However, under different discount parameters, different transportation strategies should be chosen.Finally, the work done in this paper is summarized, the existing problems are pointed out, and the future research directions are prospected.
