面向工业互联网的制造服务协作等级协议轻量级框架研究

Research on a lightweight framework of industrial Internet-oriented manufacturing service collaboration level agreement

面向服务型制造的工业互联网平台快速发展并落地应用,其对工业数据深度感知、实时传输、快速计算分析、高度反馈响应的优势逐步凸显,也为制造服务可靠协作的执行提供了平台支撑。提出了一种基于服务等级协议(SLA,service level agreement)的制造服务可靠协作轻量级框架,包括协作服务通信与接口模块、服务等级协议数据管理模块、服务协作服务质量(QoS,quality of service)协商模块、“失效—失信—守信”评估模块、激励和惩罚机制模块,同时给出了基于SLA的制造服务协作流程,从服务可信发布、协作有效执行、任务守信完成3个方面保障制造服务协作的可靠实施。

The industrial Internet platform for service-oriented manufacturing has been developing rapidly and put into use.Its advantages of deep perception of industrial data,real-time transmission,rapid calculation and analysis,and high feedback response are gradually highlighted.It also provides platform support for the implementation of manufacturing service reliable collaboration.A lightweight framework for manufacturing service reliable collaboration was proposed based on service level agreement(SLA),including collaboration service communication and interface modules,service level agreement data management module,service collaboration quality of service(QoS)negotiation module,"failure-distrust-trustworthiness"evaluation module,incentive and punishment mechanism module.The SLA-based manufacturing service collaboration process was also given.The reliability of manufacturing service collaboration was guaranteed from three aspects:reliable service release,effective execution of collaboration,and task trustworthy completion.
