Research on comprehensive efficiency evaluation of key production facility for equipment based on rough set

Comprehensive efficiency of key production facility of equipment determines the equipment support capabilities. In order to evaluate comprehensive efficiency of key production facility of equipment, on the basis of the feasibility study on rough set theory, this article establishes the evaluation index system, and take advantage of rough set theory to equipment critical production equipment efficiency, obtain the results of the evaluation of the comprehensive efficiency of the key equipment, and analyze the reasons of low efficiency. Finally to improve overall equipment efficiency, it put forward reasonable proposals.
