任务信息驱动的 3D 打印云服务平台知识管理模型

In order to effectively assist users to complete product development tasks on the 3D printing cloud service platform, a knowledge management model for the 3D printing cloud service platform based on the task information was proposed according to the characteristics of the 3D printing cloud service platform with complex task flow and diverse task subject types. The knowledge types of the 3D printing cloud platform were sorted out, the typical task process of the platform was analyzed, and the information interaction mapping model between task stages was established. The 3D printing cloud platform model, knowledge management based on ontology semantic representation of knowledge and task is built, for a specific task stage, the integrated process properties and the attributes of the object task knowledge double filtering model is put forward, through the task object attribute semantic extension to ensure the integrity of knowledge scheme, implements the personalized knowledge service. A knowledge management system under the environment of 3D printing cloud platform is developed, and the feasibility and rationality of the management model proposed in this paper are verified by a case.
