基于分期付款条件下的最优库存模型

An optimal inventory model under the installment payment

为了有效缓解零售商的资金压力,降低购买成本,刺激订货量的增加,建立了商品在分期付款条件下的库存模型。以商品的平均成本最小为目标函数,设计了求解商品的最优订货周期的最优化算法。数值实验结果表明,当其他参数不变时,随着每期付款时间的改变,平均相关成本也改变,验证了模型及算法的可行性。

The installment payment is beneficial to promote sales,reduce inventory and promote reproduction products;Also to slow the fund pressure effectively for the retailer and stimulate the increase of the quantity of goods.Under the condition of suppliers give retailers installment,the goods inventory model is constructed based on the minimum average cost as the target,a algorithm is presented for seeking the optimal order cycle and order quantity.When the other parameters are constant,the results of numerical experiment show that the average correlation costs have changed as the each payment time changes.The examples verifies the feasibility of the model and algorithm.
