针对变质产品,考虑产品非瞬时补货的情况下,在允许延期支付且如果零售商提前还款,供应商给予零售商现金折扣优惠的条件下,建立了相应的零售商库存决策模型。对模型进行求解,得出零售商的最优订货周期及最优付款时间。最后,通过具体算例,结合灵敏度分析方法,分析了模型中参数变化对最优订货策略的影响。 Aiming at the deteriorating products and the non-instantaneous replenishment of the products, a corresponding retailer inventory decision-making model is established under the condition of deferred payments and retailers ’early repayment and retailers’ cash discounts. Solve the model, come to the retailer’s optimal ordering cycle and the optimal payment time. Finally, the influence of the parameter variation in the model on the optimal ordering strategy is analyzed by the concrete example and the sensitivity analysis method.
