【摘要】：服务型制造作为制造和服务相融合而出现的新型制造模式，对于满足顾客个性化需求和促进企业升级转型具有十分重要的意义。随着企业向服务型制造转型，传统的制造供应链也逐渐转变为同时具有制造和服务功能的混合供应链。由于混合供应链中制造和服务的本质不同，二者相互影响导致混合供应链中牛鞭效应出现很多不同于传统制造供应链的性质。研究混合供应链的牛鞭效应，对于进一步完善服务型制造和混合供应链理论及指导企业降低牛鞭效应具有重要意义。首先总结了服务型制造理论的发展，深入分析了服务型制造模式下混合供应链的特点，比较了传统制造供应链和混合供应链的区别，建立了混合供应链的牛鞭效应的定量模型。根据对实行服务型制造的企业的调研，建立了一个典型的混合供应链的系统动力学流图。采用DYNAMO语言描述模型和VENSIM软件仿真运行，仿真结果证明了混合供应链中同样存在牛鞭效应，并得到了不同信息共享情况下混合供应链牛鞭效应的变化。接下来通过对大量仿真数据的统计学分析，对混合供应链牛鞭效应影响因素的总体情况进行了研究，并着重分析了市场信息反馈的影响。最后在一些合理的假设情况下，对混合供应链进行了数学建模。分析了在几种特殊情况下延迟以及一致策略等因素对混合供应链牛鞭效应的影响，并给企业减少混合供应链的牛鞭效应提供了一些建议。研究结果表明，制造和服务混合供应链的牛鞭效应同传统的制造供应链的牛鞭效应有许多不同。信息共享能够在一定的范围内减少混合供应链的牛鞭效应，过度的依赖共享的信息将不利于进一步减少牛鞭效应。市场需求信息反馈对于混合供应链牛鞭效应有着全局性的影响，并减弱其他参数对牛鞭效应的影响程度。延迟对于制造和服务阶段有着不同的影响，而一致的策略将会导致混合供应链的牛鞭效应达到最大。这些研究结论对于指导混合供应链的管理者减轻牛鞭效应具有重要的意义。
[Abstract]:As a new manufacturing model, service-oriented manufacturing is of great significance to meet the needs of customers and promote the upgrading of enterprises.With the transformation of enterprises to service-oriented manufacturing, the traditional manufacturing supply chain is gradually transformed into a hybrid supply chain with both manufacturing and service functions.Because of the different nature of manufacturing and service in hybrid supply chain, the bullwhip effect in hybrid supply chain is different from that in traditional manufacturing supply chain.The study of bullwhip effect in hybrid supply chain is of great significance to further improve the theory of service-oriented manufacturing and hybrid supply chain and to guide enterprises to reduce bullwhip effect.Firstly, the development of service-oriented manufacturing theory is summarized, the characteristics of hybrid supply chain in service-oriented manufacturing mode are deeply analyzed, the difference between traditional manufacturing supply chain and mixed supply chain is compared, and the quantitative model of bullwhip effect of hybrid supply chain is established.Based on the investigation of service manufacturing enterprises, a typical system dynamic flow diagram of hybrid supply chain is established.DYNAMO language is used to describe the model and VENSIM software is used to simulate the operation. The simulation results show that the bullwhip effect also exists in the hybrid supply chain, and the change of bullwhip effect in the mixed supply chain under different information sharing conditions is obtained.Then, through the statistical analysis of a large number of simulation data, the overall situation of the bullwhip effect of mixed supply chain is studied, and the influence of market information feedback is analyzed emphatically.Finally, a mathematical model of hybrid supply chain is established under some reasonable assumptions.The effects of delay and consistent strategy on bullwhip effect in hybrid supply chain are analyzed in several special cases, and some suggestions are provided for enterprises to reduce bullwhip effect in hybrid supply chain.The results show that the bullwhip effect of manufacturing and service hybrid supply chain is different from that of traditional manufacturing supply chain.The information sharing can reduce the bullwhip effect of the mixed supply chain to a certain extent, and the excessive reliance on the shared information will be unfavorable to further reduce the bullwhip effect.The feedback of market demand information has a global influence on bullwhip effect in hybrid supply chain and weakens the influence of other parameters on bullwhip effect.Delay has different effects on manufacturing and service phases, and consistent strategy will lead to the maximum bullwhip effect in hybrid supply chain.These conclusions are of great significance to guide the managers of mixed supply chain to reduce bullwhip effect.
