Research on the Process Layout Evaluation of Rail Vehicle Assembly Workshop in the Lean Intelligent y relational analysis is used to calculate gray correlation between the current state and the ideal level of each indicator, so as to achieve a quantitative evaluation. Three typical urban rail vehicle assembly workshops of CRRC are evaluated, and the evaluation results are consistent with the actual situation.
