英国论文听证会：EOQ模型的弱点
EOQ模型存在一定的缺陷。例如，据评估，EOQ模型的主要缺点是在计算中忽略了存货的账面成本，从而低估了账面成本。在这种情况下，评估模型没有考虑与提前时间增加、质量反馈时间增加和灵活性丧失相关的成本(Finch, 2008)。EOQ模型的另一个弱点是，假设已知的年度库存需求是有问题的。此外，预期需求与实际需求之间存在差异的概率导致了对经济订单数量的错误估计(Khan and Jain, 2013)。此外，该模型还涉及到一些计算问题。

因此，有必要采取一种新的替代方式来管理库存。公司可以采取准时制或JIT的方式对库存进行有效管理。这种方法的使用将有助于减少库存和订购成本(Waters, 2008)。这是因为当公司使用JIT时，他们保持低水平的库存，并在需要的时候购买少量的材料和产品(Pride, Hughes and Kapoor, 2009)。它还确保供应商提供高质量的产品。这种方法也有助于减少浪费，大大降低库存成本。

There is certain weakness of the EOQ model. For instance, it is evaluated that the main weakness of the EOQ model is that it underestimates the carrying costs because it ignores the non-financial costs of carrying inventory in the calculations. In this, it is assessed that the model does not consider the cost related to increased lead time, increase in quality feedback time, and lost flexibility (Finch, 2008). The EOQ model has another weakness that the assumption of a known annual inventories demand is open to question. Additionally, the probability of a variance between the expected and actual demand contributes to the wrong estimation of the economic order quantity (Khan and Jain, 2013). Moreover, some computational problems are also associated with this model.

Therefore, it is necessary to adopt a new alternative way to manage inventory. The company can adopt just in time or JIT approach for the effective management of inventory. The use of this method would be helpful to reduce the inventory and ordering cost (Waters, 2008). It is because when companies use JIT, they maintain low levels of inventory, and purchase materials and products in small quantities whenever these are needed (Pride, Hughes and Kapoor, 2009). It also makes sure that the suppliers are providing high-quality of products. This method is also helpful in eliminating the waste and reducing the cost of inventory significantly.
