中文摘要
      考虑供应商存在产能限制时,研究因库存不足或不精确产生的两种市场搜索模式——顾客搜索模式和零售商搜索模式下零售商联合订购和定价决策,并同已有文献中未考虑产能及库存不确定因素的结论进行比较,得出当产能随机因素变化区间足够大时,零售商的定价决策不变,而将增加订购量;反之,则将降低零售价格。此外,顾客搜索模式下的最优均衡安全库存和零售价格均高于零售商搜索模式下的最优值。通过对搜索强度进行敏感性分析,发现在顾客搜索模式下,随着搜索强度的增加最优均衡安全库存、零售价格和销量将同时增加;而在零售商搜索模式下,只有满足一定条件时上述结论才成立。最后在模型中引入缺货惩罚成本及运输成本,以扩展模型的适用性。
英文摘要
       This paper discusses joint decision on inventory and pricing control considering supplier’s capacity constraint in two types of market search, Customer-Driven Search (CDS) and Retailer-Driven Search (RDS), due to lack or imbalance of inventory. By comparison between our results and those of existing literature without supplier’s capacity and inventory uncertainty, we concluded that when the variation of random capacity is large enough, the retailer will increase order quantity instead of changing pricing decision. Otherwise, to reduce retail price is a better choice for the retailer. Furthermore, the equilibrium safety stock and retail price in CDS are always higher than those in RDS. Then, through analyzing the sensitivity of search intensity, we demonstrate that the equilibrium safety stock, retail price and sales are increasing in search intensity in CDS, however this is not always true in RDS. Finally, penalty cost of stockout and transportation cost are considered to extend our model.
