考虑到实际库存管理中的产品缺陷问题,研究了含模糊随机缺陷率且允许缺货的经济订购批量模型,并运用模糊随机理论将其转化为确定模型,设计了模糊随机模拟仿真算法进而确定其最优订购策略。算例分析表明,随着模糊随机缺陷率期望值的增大,最优订货量增大,最大利润相应减少。
considering the problem of defective items in the actual inventory management,the economic order quantity model with fuzzy random defective rate and backorder is proposed.The model is transfered into the crisp model with the fuzzy random theory.Optimal order policy is obtained with fuzzy random simulation algorithm.Numerical example shows that the optimal order quantity increases and maximization profit decreases as the expected value of fuzzy random defective rate increase.
