【摘要】：全球经济开始逐渐朝着一体化的趋势发展,供应链各个环节企业之间的合作与竞争同时存在,且日趋明显。目前我国供应链企业中存在很大一个困境,各个环节的企业之间的联系较小,但是随着市场竞争不断加剧,供应链中各个环节企业之间需要相互协作,设计出更好的合作契约来达到共赢,成为供应链协调发展的关键点。供应链中的不同企业,由于库存的不确定性容易导致库存损失,容易导致不能及时满足消费者需求,所以我们需要选择合适的方式来有效监控库存。采用RFID技术,可以保证供应链环节透明可监控,进而提高供应链中各个环节企业的整体效益。基于此背景,在分析国内外相关研究现状的基础上,研究了在RFID技术实施的前提下,如何来实现供应链协调和库存优化问题。供应链协调问题研究分析了供应商和销售商之间的两级供应链,详细的讨论了供应链在采用了契约函数后,分摊射频识别标签可以帮助销售商提高收益降低风险。对于供应链中的库存优化问题,研究在不同情况下的订货量问题,针对是否存在替代品和RFID技术的不同情况,销售商制定的订货策略应该是完全不同的。对于实施RFID技术的销售商来说,在适当的RFID标签费用系数的前提下,实施RFID技术比未实施RFID技术获得的利润会更高。但是当消费者的需求量比较少时,采用RFID技术不但不会给销售商带来太大利润,反而会降低其收益,从而针对上述不同情况得出了最优订货量。本文针对现在供应链协调及库存优化的实际情况,综合以上理论和模型研究的基础,充分认识到了RFID技术可以为企业的发展带来巨大的价值,所以我们应当不断挖掘射频识别的新模式,来扩大RFID技术的应用范围。
[Abstract]:The global economy is beginning to develop towards integration, and the cooperation and competition among the enterprises in each link of supply chain exist simultaneously and become more and more obvious. At present, there is a big dilemma in the supply chain enterprises in our country. The relationship between the enterprises in each link is relatively small. However, with the increasing competition in the market, the enterprises in the supply chain need to cooperate with each other. Design a better cooperation contract to achieve win-win, become the key point of the coordinated development of supply chain. Different enterprises in the supply chain, because of the uncertainty of inventory easily lead to inventory loss, easy to lead to unable to meet the needs of consumers, so we need to choose a suitable way to effectively monitor inventory. The use of RFID technology can ensure that the supply chain is transparent and can be monitored, thus improving the overall efficiency of the enterprises in each link of the supply chain. Based on this background, based on the analysis of domestic and foreign related research status, this paper studies how to realize supply chain coordination and inventory optimization under the premise of implementation of RFID technology. In this paper, the two-level supply chain between supplier and vendor is analyzed, and it is discussed in detail that after the supply chain adopts contract function, the allocation of RFID tag can help the vendor to increase the profit and reduce the risk. For the inventory optimization problem in the supply chain, the order quantity problem under different conditions is studied. For the different situations of whether there are alternatives and RFID technology, the ordering strategy should be completely different. For the vendors who implement RFID technology, under the premise of proper RFID tag cost coefficient, the profit of implementing RFID technology will be higher than that of RFID technology. But when the consumer demand is less, the adoption of RFID technology will not bring too much profit to the seller, but will reduce its profit, so the optimal order quantity is obtained according to the above different conditions. In view of the actual situation of supply chain coordination and inventory optimization, this paper fully recognizes that RFID technology can bring great value to the development of enterprises. Therefore, we should continuously excavate the new pattern of RFID to expand the application of RFID technology.
