The evaluation method of knowledgeable manufacturing system based on knowledge mesh

The evaluation method of knowledgeable manufacturing system is proposed to solve the selection of system caused by the diversity of knowledge mesh. According to the structure and generation of knowledge mesh, the metrics, which are the satisfaction degree of function, the redundancy degree of function, the relative amount of knowledge, the redundancy degree of multiple-number, the order degree and the interested degree of user, are proposed from the quantitative and qualitative aspects. The properties of relative amount of knowledge and redundancy degree of multiple-number are supposed to reveal the operation law. And the redundancy degree of multiple-number can distinguish the same knowledge meshes whose multiple set is different. Order degree is used to measure the rationality of structure. Finally, the metrics are exemplified and shown effectiveness and feasibility.
