采用贴现率来衡量资金的时间价值,将资金时间价值引入到JIT生产库存模型中,探讨了质检不完备条件下由一个品牌商与一个OEM供应商构成的JIT生产—库存决策问题。分别建立了通胀环境下的品牌商成本模型、OEM供应商成本模型及集成JIT生产—库存系统总成本模型。最后进行了算例分析,给出了最优供货次数和最优供货量。敏感性分析表明最小成本随贴现率的增大而减小;随犯质检一类误差的概率增大而增大,且呈现快速增大趋势;随犯质检二类误差的概率增大而减小,但最小成本对质检二类误差不敏感;随有限计划期的延长而增大。所获结论对企业管理者在通胀环境下做出扩大生产的决策提供了依据。
By using the discount rate to measure the time value of funds, the time value of funds is introduced into the JIT production inventory model, and the JIT production-inventory decision-making problem consisting of one brand owner and one OEM supplier under the condition of incomplete quality inspection is discussed. The model of the cost of the brand, the model of the cost of the OEM supplier and the integrated model of the integrated JIT production-inventory system are respectively established in the inflation environment. Finally, an example analysis is given, giving the optimal delivery times and the optimal delivery. Sensitivity analysis shows that the minimum cost decreases with the increase of the discount rate, increases with the probability of a type of error in the quality inspection, and shows a tendency of rapid increase. With the increase of the probability of class II error Decrease, but the minimum cost is not sensitive to the second type error of quality inspection; it increases with the extension of the limited plan period. The conclusions obtained provide the basis for the decision-making by the managers of enterprises in expanding their production in an inflationary environment.
