1原制造商专利保护对再制造供应链技术创新策略的影响显示文摘为提升再制造技术创新水平以增强其社会认可度,运用博弈论研究了原制造商专利保护对再制造商技术创新策略的影响。在推导包含产品技术创新水平的消费者需求函数的基础上分别构建并求解了无技术创新(NTI)、无专利保护技术创新(TI)、专利保护技术创新(PTI)下的供应链模型,通过理论分析和数值仿真对供应链绩效及成员模式偏好进行了详细分析。研究表明,技术创新水平分别与再制造节约成本和消费者对再制品的估值程度正相关,专利保护下的技术创新水平低于无专利保护;经销商开展技术创新时原制造商收取的单位专利许可费显著提高,并与技术创新效率负相关;再制造商、绿色消费者以及社会福利的模式偏好为TINTIPTI,原制造商的模式偏好为PTINTITI,而供应链系统以及普通消费者的模式偏好则取决于消费者对再制品的估值。朱宾欣 马志强 吴宁 LEON Williams 2018计算机集成制造系统2018,24,9:12
2网络外部性对线下商定价和服务提供策略的影响显示文摘在面临在线品竞争的情形下,研究了网络外部性对线下商定价和服务策略的影响。考虑线下商服务程度既定,给出了三种市场模式的形成条件,分析了网络外部性对各种市场模式产品定价、需求、线下商利润以及消费者剩余的影响,并进一步探讨了网络外部性下的服务提供策略。研究表明:较小的网络外部性形成线下商垄断,价格与网络外部性无关;较高的网络外部性将引起在线品竞争,线下商降价以吸引消费者,虽有助于提升市场份额,但会降低线下商利润;网络外部性适中时市场处于威胁模式,产品价格和线下商利润取决于网络外部性折扣与渠道估值的相对大小。垄断模式下网络外部性会激励线下商提高服务程度,竞争模式下则会促使线下商降低服务程度,并很大程度上损失消费者剩余。朱宾欣 马志强 高鹏 Leon Williams 2019系统工程2019,37,4:5
3考虑声誉效应的众包竞赛动态激励机制研究显示文摘将声誉效应引入众包竞赛的激励机制可以促使接包方为考虑未来绩效收益而提高当前努力.建立并求解了显性和隐性声誉效应下连续两个任务阶段的动态激励模型,探讨了显性声誉修正系数、隐性声誉系数以及参赛者数量对激励效果的影响,并与无声誉激励机制进行了对比.研究表明,声誉激励机制通过单位绩效激励强度和固定奖励水平两条途径起作用,增大隐性声誉系数有助于提高每个任务阶段的努力程度,显性声誉不确定性则会降低第2任务阶段的努力程度;各种条件下实施声誉激励对第1任务阶段中的努力程度和单位绩效奖励的影响存在不确定性;参赛者数量的增加有助于弱化第1任务阶段中棘轮效应,但也会降低声誉激励机制对努力程度的正向价值,扩大声誉激励机制对单位绩效奖励的负向价值.朱宾欣 马志强 LEON Williams 2020运筹与管理2020,29,1:4
4Impact of Crowdsourcee’s Vertical Fairness Concern on the Crowdsourcing Knowledge Sharing Behavior and Its Incentive Mechanism显示文摘This paper examines in detail the impact of the crowdsourcee’s vertical fairness concern on the knowledge sharing incentive mechanism in crowdsourcing communities.The conditions for the establishment of the incentive mechanism are analyzed and the impact of fairness concern sensitivity on expected economic revenues of both sides as well as the crowdsourcing project performance is studied by game theory and computer simulation.The results show that the knowledge sharing incentive mechanism can only be established if the ratio between the performance improvement rate and the private cost reduction rate caused by shared knowledge is within a certain range.The degree of the optimal linear incentives,the private solution efforts,and the improvement of knowledge sharing level are positively correlated with the sensitivity of vertical fairness concern.In the non-incentive mode,the ratio between the performance conversion rate of private solution effort and the performance conversion rate of knowledge sharing effort plays an important role in moderating a crowdsourcing project’s performance.The authors find that the number of participants is either conducive or nonconducive to the improvement of performance.The implementation of knowledge sharing incentive can achieve a win-win situation for both the crowdsourcer and the crowdsourcee.ZHU Binxin LEON Williams PAUL Lighterness GAO Peng 2021Journal of Systems Science & Complexity2021,34,3:3
5考虑解答者公平关切的众包竞赛知识共享激励显示文摘研究了解答者之间的横向公平关切特征对众包竞赛发包方知识共享激励的影响。在构建公平关切下解答者效用函数的基础上,建立并求解了无知识共享激励模型(NKS)和知识共享激励模型(KS),用理论分析和数值仿真的方法研究了公平关切敏感度对发包方最优知识共享激励程度、解答者最优私有解答努力程度及知识共享努力程度、众包项目绩效,以及双方期望经济收益的影响,并与无知识共享激励进行了对比。研究表明:解答者公平关切心理能降低实施共享知识激励机制的门槛,并提升发包方最优知识共享激励程度;解答方知识共享努力与公平关切负相关,但私有解答努力与之正相关;众包项目绩效、发包方绝对经济收益与公平关切的关系取决于解答努力绩效转化率和知识共享努力绩效转化率之间的比值;知识共享激励机制能实现发包方和解答者双方经济利益的共赢,且其经济价值随公平关切敏感度的增大而提高,并受到参赛人数的调节作用。朱宾欣 马志强 Leon Williams 高鹏 2020系统管理学报2020,29,1:2
