Abstract: The reliability growth of electromechanical products is a continuous process of addressing reliability defects, which is very important for manufacturing enterprises. At present, research on the reliability growth of electromechanical products mostly focuses on the reliability defects of the products themselves, ignoring the fact that manufacturing enterprises are the executors of product reliability related work. Improving the organizational reliability capability of manufacturing enterprises can enhance the reliability of electromechanical products. In order to understand the current situation of organizational reliability capability (ORC) in electromechanical product manufacturing enterprises and make improvements, this paper establishes an ORC evaluation indicator framework for electromechanical product manufacturing enterprises and evaluates it using the grey evaluation method. Firstly, an evaluation indicator framework for ORC is established based on enterprise research. Secondly, the ORC of electromechanical product manufacturing enterprises is evaluated by combining the three-parameter interval grey number and projection index function. Then, the evaluation results are analyzed from multiple perspectives to understand the current situation and shortcomings of ORC and guide its improvement. Finally, the evaluation indicator framework and method are explained through practical application in CNC machine tool manufacturing enterprises, and the effectiveness of the framework and method is demonstrated through the MTBF growth of CNC machine tools.
