面向工业互联网平台的关键设备服务生态模式优化与合同设计

近年工业互联网平台驱动机队性能服务、用户间共享、制造服务共创共享等关键设备新兴服务模式实践，导致服务模式之间的复杂竞争与协作，同时赋予制造商服务合同决策新环境。针对实践与理论之间缺口，本项目从制造商视角提炼出平台服务生态模式优化与合同设计新问题：从战略层研究平台服务模式博弈模型，揭示模式间交互作用机制及最优组合条件，探讨制造商的平台服务生态平衡控制策略。运作层考虑制造商信息优势、平台外部性、互助利他行为等合同新特征，首次提出以设备台数作为平台正外部性测度，以信号传递博弈为框架研究机队性能服务合同设计方法，探讨合同与平台外部性传递服务质量信息的机制；以信号甄别博弈为框架研究用户间设备共享的运维服务合同设计方法，探讨用户与制造商的合同选择偏好机制；以委托-多代理理论研究制造服务共创的团队合同及激励机制设计方法。最终形成平台服务生态模式与合同决策新方法，为制造企业平台服务运营提供科学指导。

Industrial internet platforms recently drive innovations of the service modes for critical-mission equipment, such as the fleet performance service, the equipment sharing service among customers, and the co-manufacturing sharing service, which brings the complex competition and cooperation among modes and endows the manufacturer with new contracting setting. In order to bridge the gap between industry and theory, new problems of optimizing ecological service mode and designing service contract are proposed from the perspective of manufacturing firm as follows. Strategically optimizing ecological service modes is modeled in game theory framework, the interplay mechanism between service modes is explored, the optimal condition is derived for the combination of service modes, and then the control policies are investigated for service ecological equilibrium on the platform. Tactically the new characteristics of contracting setting are focused on, such as the firm’s informational advantage, the platform externality and altruism behavior. A design problem of service contract is firstly modeled in signaling game for the fleet performance service, in which the size of the fleet is proposed as a measure of the positive effect of the platform externality. Furthermore, the interplay between the contract and the platform externality is explored how to signal the service quality. Secondly, a design problem of maintenance contracts for the equipment sharing service among customers is modeled in screening game framework, and then the preference of the customer and the firm selecting contracts is investigated. Finally, the design method and its incentive mechanism of team contract are studied for an emerging co-manufacturing sharing service. The expected results in the proposal will bring new decision-making methods for ecological service mode and service contract on the industrial internet platform and further provide the theoretical guidance for platform operation service in manufacturing industry.
