现代漂流是一种大众化的、以娱乐、探险为目的的休闲旅游活动。近些多年来,游客对国内漂流景区服务质量的投诉越来越多,服务质量问题已严重制约我国漂流旅游业的发展。从游客体验质量和提高自身竞争力的角度出发,漂流景区应坚持全面质量管理原则,重点抓好服务触质量管理,以此为游客提供整体的、高水平的服务体验。  相似文献

针对由单一制造商和单一零售商组成的供应链,考虑制造商或零售商在资金闲置与资金约束时向银行存款与贷款的情形,研究了供应链Stackelberg定价策略。首先,给出了市场需求函数;然后,考虑销售收入的零存整取收益、利润的存款收益以及贷款损失,分别构建了制造商资金约束与零售商资金约束两种情形下基于提前支付且考虑银行存贷的供应链成员利润函数;进一步地,依据Stackelberg理论,确定了两种权力结构下供应链的最优策略;在此基础上,分析了零存整取利率、存款利率和贷款利率对供应链最优策略的影响;最后,针对不同资金约束对象与不同权力结构,对比分析了银行利率对供应链最优策略的影响差异,揭示其背后的影响机理。研究结果表明,三种银行利率均会影响供应链的最优策略,相对于供应链权力结构,其影响与供应链资金约束对象更加相关。  相似文献

针对制造商作为核心企业的逆向供应链,面临库存设施容量限制,以及回收量为回收价格和回收努力的随机线性函数关系问题,本文分别讨论了回收量在库存范围之内和超出库存范围两种情况下,由制造商负责租借额外库存时,逆向供应链成员企业的决策行为。得出,制造商需要向第三方仓储系统租借库存和有能力承受回收产品所需的库存容量范围,以及在不同库存范围内逆向供应链成员的最优决策和最优收益。  相似文献

不同库存决策机制对供应链绩效的影响:确定性模型   总被引:2,自引:0,他引:2  
许多成功企业的经验表明,供应链重构是企业增强竞争力的主要措施之一.要成功地进行供应链重构,必须要对各种供应链重构策略进行分析.在经济订货量(EOQ)模型假设下,针对由一个制造商与一个零售商所构成的供应链,研究了零售商优先决策、制造商优先决策以及联合决策3种供应链管理机制对供应链绩效的影响.通过理论分析与数值模拟方法,说明了在这种供应链中存在"双重边际性"现象,这将有助于决策者选择合适的供应链管理机制,并为下一步进行供应链重构打下理论基础.  相似文献

改革开放以来,我国的旅游业发展迅猛,国际旅游、国内旅游都形成了相当的规模。但是这种快速的发展是以数量的扩张和粗放型的经营换皋的。“宏观报喜,微观报忧”,充分说明了产业内部蕴涵的矛盾。本文主要从我国旅游景区服务质量存在的问题及解决对策来进行研究。  相似文献

针对由一个制造商和两个零售商组成由制造商直接回收旧品的闭环供应链系统,利用博弈论方法,研究了零售商决策权均衡的"E"情形和其中一个零售商具有决策优先权的"A"情形对于运作效益的影响.通过结果比较分析,可知"A"情形相对于"E"情形,制造商的边际利润增大而最优利润均下降,但两个零售商的边际利润和最优利润均有所增加.所以"A"情形中,制造商的最优利润降低,主要是由于回收努力系数的降低所致,但边际利润增加了,同时,回收努力系数较小,所以对于刚刚涉足产品回收和再制造的制造商来说,"A"情形不失为一种较好的选择;但"E"情形是制造商积累了闭环供应链管理经验后的终极选择.  相似文献

研究了委托人(业务购买方)对于承包人(业务供应方)生产成本具有非对称信息时的最优合约设计问题.基于委托人视角,给出了委托人如何诱导代理人报告自己真实成本信息的逆向选择模型,并刻画了最优合约的特征.结果表明:给出的合约能够达到诱导代理人讲真话的目的;在信息非对称条件下,委托人由于信息缺乏受到了损失,而低成本类型的代理人获得了额外的信息租金;在非对称信息条件下,最优合约的参数配置受到委托人事前信念的影响.  相似文献

VMI下的两级供应链库存决策模型研究   总被引:2,自引:0,他引:2  
在季节性商品销售环境下,考虑由一个供应商和两个零售商所组成的两级供应链模型.引入 VMI 运行机制,讨论供应商的最优库存决策.传统上,供应商总是在销售季节开始前确定各个零售商处的库存量,而不会对两个零售商处的库存进行调节.研究当供应商有能力在销售季节开始之初对两个零售商处的库存进行调节时其最优决策将发生的变化.文章进一步讨论了库存转运对零售商以及供应链整体性能所带来的影响.分析了单位转运价格等参数变动对最优解的影响.用一个算例对结论进行了说明.  相似文献

We examine periodic review supply chain models where order quantity and shipping frequency are both decision variables and decision-making rights are split between supply chain agents. We address two general questions: (1) when does decentralized decision making result in the greatest loss in supply chain performance; and (2) what effect does the distribution of channel power have on performance loss. We characterize optimal policies where possible in each scenario and we use numerical analysis to generate insights. We find that performance losses from decentralized control are somewhat limited in our results due to risk pooling and that the magnitude of performance loss is strongly influenced by the relative holding and penalty costs, but somewhat invariant to demand uncertainty. Furthermore, we find that concentrating channel power with the supplier can lead to supply chain profits that are very close to a centralized scenario, but also results in lower customer service levels.  相似文献

本文研究考虑企业社会责任(CSR)闭环供应链的定价及销售努力问题,在制造商、零售商以及二者联合承担CSR三种模式下,分析了CSR行为对闭环供应链销售努力及定价策略的影响。研究表明,无论在何种CSR分担模式下,成员企业的CSR行为不仅有利于降低产品价格,提高零售商的销售努力水平、产品销量及废旧产品回收效果,还有效的增加了制造商的社会福利、第三方及系统的总利润。当制造商或零售商单独承担CSR时,第三方及闭环供应链整体的利润均相等且大于二者联合承担CSR时。当制造商和零售商联合承担CSR时,二者的社会福利均大于其单独承担CSR时,且主导零售商的社会福利较之制造商更大。  相似文献

We study the impact of coordinated replenishment, a popular supply chain initiative, on a quality control system. We use the (Q, S) policy to manage a two-item inventory control system. If the items are jointly replenished, the number ordered for each item varies from lot to lot. As the number varies, the sampling plan will also be changed. Companies have to determine sampling plans to minimize quality cost when the order is mixed with several items and the number of each item varies from order to order. Management's primary concern is to determine the optimal sampling sizes and acceptance numbers for all items in an order.  相似文献

We consider a detailed mathematical formulation for the problem of designing supply chain networks comprising multiproduct production facilities with shared production resources, warehouses, distribution centers and customer zones and operating under time varying demand uncertainty. Uncertainty is captured in terms of a number of likely scenarios possible to materialize during the lifetime of the network. The problem is formulated as a mixed-integer linear programming problem and solved to global optimality using standard branch-and-bound techniques. A case study concerned with the establishment of Europe-wide supply chain is used to illustrate the applicability and efficiency of the proposed approach. The results obtained provide a good indication of the value of having a model that takes into account the complex interactions that exist in such networks and the effect of inventory levels to the design and operation.  相似文献

The goal of this paper is to provide a first step in the development of a coherent set of modelling methods for supply chain reengineering. This paper shows that different fields of attention in supply chain management should be approached with different modelling methods. Three modelling methods are presented: the event process chain (EPC) method; the activity chain model (ACM) method; and the GRAI grid method (adjusted for supply chains). EPC modelling focuses on time relationships between primary processes/functions, and is customer oriented. ACM modelling focuses on functions/processes and information flows. GRAI focuses on decision structures and information flows. The three methods are described, and an application of the methods to a case study company is presented. This paper concludes with a comparison of the methods and a discussion of their applicability.  相似文献

基于产品质量内生的制造/再制造最优生产决策   总被引:1,自引:0,他引:1  
从制造商的视角出发,将产品质量水平作为内生变量,并考虑质量水平对返回废旧产品的降级率的影响,分别讨论单寡头、双寡头非合作以及双寡头合作市场中,制造商最优制造/再制造决策策略.根据需求市场对产品价格和质量水平的敏感性,进行经济性分析,权衡制造商的制造/再制造的收益、生产成本,优化产品质量水平,帮助企业决定合理的再制造比例.研究结果显示:随着降级率的增大,制造商会降低再制造比例;制造商设置的降级率在不同模式下对利润与价格的影响是有差异的.  相似文献
