摘要
建立了三角型模糊需求与模糊提前期且允许缺货的周期性盘点库存模型。利用可信性测度理论,给出了其期望值模型。分析了期望值模型的盘点周期与目标存储水平间的关系。运用模糊模拟技术设计了一最优库存策略的算法。算例分析表明,提前期和需求模糊性的增大会产生更大的费用。
A periodic review inventory model allowed shortage was studied with triangle fuzzy demand and fuzzy lead-time. The expectation formula is obtained based on the credibility theory. The relation between review periodic time and optimal stock level were analyzed. By using the theory of fuzzy simulation, an algorithm is developed to find the optimal inventory policy. Results show that the increase of lead-time and fuzzy will produle more cost.
