【Abstract】Data and knowledge-driven service-oriented smart maintenance decision-making is becoming a current research topic in complex multi-component systems. In it, the comprehensive data and knowledge from different stakeholders such as users, OEMs, and service providers contribute to determining the optimal decision-making schemes. However, the traditional centralized systems or platforms lead to the reluctant cross-organization knowledge sharing for each stakeholder. Meanwhile, although the promising blockchain technology is fit to solve the centralized sharing problems, it little considers the service oriented maintenance decision-making (SOMD) processes. Moreover, it also ignores the collaborative sharing relationships that generate requests, induce services and respond knowledge among different stakeholders. Thus, in order to solve these problems, this paper focuses on the SOMD processes, and innovatively proposes a decision-making oriented collaborative knowledge sharing framework and multi-channel distributed blockchain network MK ShareNet. The network architecture, lifecycle smart contracts, token reward mechanisms, and collaborative knowledge transaction operation logics are all designed. Finally, the prototype system on complex CNC honing machining tools is implemented and the collaborative sharing is verified. It shows that the proposed MKShareNet and system could effectively implement the sequential and incentive knowledge sharing among different stakeholders for maintenance planning.
