无理由退货政策下的概率销售策略

本文研究了无理由退货政策下,零售商是否应该提供概率产品,以及概率产品和传统产品应该如何定价的问题.由于消费者会根据对不同产品的期望满意度决定是否购买,零售商需要考虑如何提供最优的概率产品与传统产品的产品组合.本文同时考虑了零售商的销售策略和产品定价决策,发现消费者满意度对零售商的决策有十分重要的影响.特别地,随着消费者满意度的上升,零售商的利润反而有可能会降低.数值分析显示概率产品的随机性和消费者满意率对零售商的概率销售决策和利润有显著影响.     

零售商的斯塔克伯格团购博弈分析

团购成员企业在相互合作的同时也相互竞争.论文同时考虑了团购成员的合作与竞争,针对成员先后决策,序贯博弈的情形,研究了两家零售商面对斯塔克伯格团购博弈时的选择以及相应的库存和定价策略,并解出了两家零售商库存、定价的均衡解.研究结果还表明,当两家零售商的市场潜力差距较小,即两家零售商实力更相近时,双方都偏好团购.此外产品替代程度和批量折扣程度会综合影响两家零售商的定价,订购量以及利润,且往往与双方的市场实力差距有关.     

Synthesis and Application of a Polymeric Crosslinking Agent for Improving Fixation of Vinylsulfone-type Dyes on Cotton by a Pad-drycure Process

A new class of novel polymeric crosslinging agent （NPCA）, which contained silane coupling group and the epoxy groups, was designed and synthesized in our laboratory. NPCA was a non-formaldehyde multifunctional crosslinking polymer. The cotton fabrics dyed with 8.0% （owf） Vinylsulpone-type dyes were treated with 3.0%- 4.0% NPCA, 0.5 mol/L potassium thiocyanate as a catalyst, then padded through two dips and two nips to reach a wet pickup of 80%- 85%, then dried at 80℃ for 2 minutes and cured in oven at 140- 150℃ for 3 minutes. Crocking fastness and fixation （%） were improved with up to 1.0 -1. 5 units, 35%- 50%, respectively. And there was little difference between the color yield of dyed fabrics before and after the treatment at certain conditions. The possible crosslinking mechanism of NPCA was also investigated. It was concluded that NPCA can improve colorfastness of cotton fabric by means of the three-dimensional network, covalent bonding and other molecular forces.     

全渠道服务系统的排队信息披露策略影响研究

实践中,越来越多的餐饮服务企业开始实施线上线下全渠道运营模式.本文研究了全渠道服务运营中的不同信息披露策略对企业、顾客和社会的影响.通过建立比较线上渠道队长信息可见和不可见两种情形下的排队系统模型,本文分析了信息披露对系统均衡顾客数、顾客个人效用以及社会福利的影响.研究结果表明:当线上线下渠道等待成本差距不大时,商家披露信息能提高系统均衡顾客数;当商家披露队长信息时,顾客的个人效用反而有可能受损;商家披露信息能提升社会福利.最后,本文完整刻画出了信息披露后系统顾客数和社会福利同时提高的具体条件,给企业更好的施行全渠道服务运营提供参考和建议.
