A comprehensive maintainability evaluation methods for subsystems of CNC machine tools
Abstract
Maintainability is used to evaluate product’s ability to return to normal operation state when a product is in use. In this paper, a comprehensive maintainability evaluation model for subsystems of CNC machine tools is proposed by building a hierarchy-structured model based on the AHP and incorporating information entropy method. The model is used to evaluate maintainability for subsystems of CNC machine tools. At last, we use a type of machining centers as an illustrative example to comprehensively evaluate maintainability of subsystems and draw the conclusion that CNC system has the best maintainability. The analysis result shows that the method is effective and feasible with important value in engineering application.
