棉花价格波动下棉纺织企业库存优化

摘要

Inventory optimization method of cotton textile enterprises under cotton price fluctuation was discussed.The current situation of cotton textile enterprises material inventory management was introduced.Cotton price fluctuation factor was added into tradition economic order quantity model.Under the condition of allowing shortages,economic order quantity model was created and the best inventory strategy was gained under these assumptions.It was proven that the model could reduce average inventory and total inventory cost through a cotton textile enterprise instance.The sensibility of every affecting factors were analyzed and the effects range from high to low were rates of demand,per unit change order cost,cotton price,interest of funds,per unit change storage cost and rate of shortage.It is considered that the model has practical and still needs to be further improved,because the considering influence factor is relatively less.%探讨在棉花价格波动的情况下优化棉纺织企业库存的方法.介绍了当前棉纺织企业原材料库存管理现状,在传统经济订货批量模型中加入棉花价格波动因素,建立了允许缺货条件下的经济订货批量模型,得到假设条件下的最优库存策略.通过某棉纺企业实例验证了该模型可以降低平均库存量和总库存成本;对各影响因素做了敏感性分析,影响幅度从大到小依次为需求率、单位变动订货成本、棉花价格、资金利息、单位变动储存成本、缺货率.认为:该模型虽然具有一定实用性,但是考虑的影响因素相对较少,还需进一步完善.
