【摘要】：随着市场竞争的越发激烈，商品生命周期缩短，市场需求波动变大，供应链的订货提前期与库存误差问题，对供应链的收益影响巨大。无线射频识别(RFID)技术成为改善库存误差问题以及订货提前期的有效途径。但RFID技术的应用带来成本的增加，供应链企业不能直观地分析出投资RFID技术带来的收益。因此，研究供应链投资RFID技术的决策问题意义重大。以往的研究仅仅考虑库存误差或订货提前期单一情况，本文针对由单供应商和单零售商构成的二级供应链，考虑RFID技术投入后库存误差及订货提前期同时得到改善，，采用数理模型研究方法，对RFID技术的投资决策进行了定量研究。首先，针对投资RFID技术前，考虑库存误差以及正常订货提前期，对报童模型进行改进，分别建立了集中决策型和分散决策型供应链收益模型，运用Stackelberg博弈方法求得最优解。同时为了消除双重边际化效应的影响，实现供应链的协调，针对分散决策型供应链设计了回购契约以及收益共享契约，构建了不同契约下分散决策型供应链收益模型，并求得最优解。然后，考虑投资RFID技术后库存误差与订货提前期同时得到改善，构建了投资后的集中决策型与不同契约下分散决策型供应链收益模型，分析了投资RFID技术对供应链收益以及协调策略的影响。最后，通过对比分析投资前后供应链的最大期望收益，得出了投资RFID技术的决策条件。并通过MATLAB软件进行了数值仿真分析，验证了结论。本文的研究可为供应链企业投资RFID技术决策提供理论参考。
[Abstract]:With the fierce competition of the market, the commodity life cycle is shortened, the market demand fluctuates greatly, and the order lead time and inventory error of the supply chain have a great impact on the profit of the supply chain. Radio frequency identification (RFID) technology is an effective way to improve inventory error and lead time. However, the application of RFID technology leads to the increase of cost, and supply chain enterprises can not directly analyze the benefits of investment in RFID technology. Therefore, it is of great significance to study the decision-making of RFID technology in supply chain investment. In the past researches only consider the single stock error or order lead time. In this paper the inventory error and the order lead time are improved after the RFID technology is taken into account in the two-stage supply chain which is composed of single supplier and single retailer. The investment decision of RFID technology is studied quantitatively by means of mathematical model. Firstly, considering the inventory error and normal order lead time before investing in RFID technology, the newsboy model is improved, and the centralized decision model and decentralized decision model are established, and the optimal solution is obtained by using the Stackelberg game method. At the same time, in order to eliminate the influence of double marginalization effect and realize the coordination of supply chain, a repurchase contract and a revenue-sharing contract are designed for the decentralized decision-making supply chain, and the profit model of decentralized decision-making supply chain under different contracts is constructed. The optimal solution is obtained. Then, considering the investment of RFID technology, the inventory error and order lead time are improved simultaneously, and the profit model of centralized decision making and decentralized decision making under different contracts is constructed. The influence of investment RFID technology on supply chain income and coordination strategy is analyzed. Finally, by comparing and analyzing the maximum expected return of supply chain before and after investment, the decision conditions of investing RFID technology are obtained. Numerical simulation analysis is carried out by MATLAB software, and the conclusion is verified. The research in this paper can provide a theoretical reference for the supply chain enterprises to invest in RFID technology decision.
