摘要
当供应商处于供应链节点的买方市场时,通常要求零售商提前支付一定比例购置成本作为订金.针对该问题研究零售商促销努力下存在随机需求的非瞬时变质产品批量订货定价策略,考虑零售商提前支付策略,允许部分缺货.在一定条件下可得零售商最优补货周期和局部最优定价策略,随之提出相应的求解算法.数值计算结果表明:若提前支付购置成本占比或利率增大,则零售商利润将显著减少;提前支付期限和期数均对最优利润产生消极影响;零售商采取积极促销策略可有效提升自身利润.
For perishable products, when a supplier is in the buyer＇s market of a supply chain node, it usually requires retailers to pay a certain proportion of purchase cost in advance as a deposit. The pricing and inventory lot-size policies for non-instantaneous deteriorating items with stochastic demand and promotional efforts are studied. The payment policy and shortage are considered. Under certain conditions, retailers get the optimal replenishment cycle and local optimal pricing strategy, and the corresponding solving algorithm is proposed. Numerical results show that, with the increase of the interest rate and proportion of advanced purchase cost payments, retailers＇ profits will be reduced, the prepayment period and prepayments number both have negative influence on the optimal profit, actively promote sales strategies can effectively enhance retailers＇ profits.
