摘要
基于切花产业的新兴实践,本文建立了一个具有两期货架期的易逝品再制造库存系统.该系统的显著特征在于考虑了旧产品的感知质量.关注到产品质量恶化和需求信息更新,本文将销售季节分为两个周期:第一周期的特征是需求不确定性,第二周期的特征是新旧产品的竞争.采用逆向动态规划的方法,获得企业在不同情形下的最优订购和定价决策.研究表明,再制造成本是影响企业再制造策略选择的关键因素,而剩余库存和感知质量则是影响企业生产和再制造决策的核心要素.若再制造成本较低,企业应当实施完全再制造策略;否则,应当实施部分再制造策略.在部分再制造策略中,当剩余库存水平较高或感知质量较低时,企业不进行再制造.最后,数值实验表明再制造策略有助于降低安全库存的储备,显著提升收益;减少生产量,缓解切花对环境的负面影响,具有较高的经济价值和生态价值.
Motivated by emerging practices in the cut flower industry,this paper develops a two-period inventory system with remanufacturing for perishable products.The distinctive feature of this system is to take the perceived quality of old products into account and to explore the impact of the perceived quality on firms’production and remanufacturing decisions.Focusing on product quality deterioration and demand information updating,this paper divides the selling season into two periods.Period 1 is characterized by demand uncertainty,while period 2 involves competition between old and new products.To derive optimal ordering and pricing decisions under various remanufacturing strategies for different quality levels,this paper employs an inverse dynamic programming approach.The results show that remanufacturing cost is the key factor influencing the choice of remanufacturing strategy,while surplus inventory and perceived quality are the core elements influencing the production and remanufacturing decisions.If the cost of remanufacturing is low,the firm should implement the full remanufacturing strategy;otherwise,it should implement the partial remanufacturing strategy.In the partial remanufacturing strategy,the firm doesn’t remanufacture when the level of surplus inventory is high or the perceived quality is low.Finally,numerical experiments demonstrate the dual value of remanufacturing,which aid in reducing reserves of safety stock,significantly boosting profits,and curbing production.This not only enhances economic outcomes but also contributes to mitigating the negative environmental impacts in the cut flower industry.
