中文摘要：

经典的库存模型总是假设购买者在收到所订购商品时必须立即缴付货款,然而实践中,供应商总是提供他们的客户一个确定的还款周期以增加其产品销售量,因此在库存决策中考虑商业信用的影响既是实用的也是必须的。通过对于该领域的大量文献进行回顾,将相关文献按照商业信用合同及研究主题进行了分类,并简述了代表性文章中的关键内容。最后结合已有的研究成果与库存管理的实际问题提出几个值得关注的研究方向。

英文摘要：

The classical inventory model is based on the assumption that the purchaser must pay for the items received immediately.In practice,however,the supplier may frequently offer the customer a permissible delay in payment for purchasing cost to increase sales,so it is useful and essential to determine the optimal inventory decision in the context of trade credit policy.After reviewing the research in this area and the important elements for the representative papers,we try to provide a classification of these papers based on the items of trade credit contracts and the topic we are interested in.Finally,a few research ideas are proposed based on the inventory management practice and reviews of current literature.
