Lean evaluation system of manufacturing enterprises based on full lifecycle

The production of manufacturing enterprises is a complex process. Lean production is hard to achieve lean weight reduction. It is very important to propose a lean life assessment framework. This paper evaluates the lean production level of the whole life cycle of the company by using the fuzzy theory and the neural network technology, establishes a scientific and systematic framework of the lean evaluation index of the whole life cycle, and establishes the evaluation model of the fuzzy neural network. The example analysis shows that the actual output value of the fuzzy neural network model is not much different from the predicted output value, which indicates that the model has high-prediction accuracy. The experimental results further verify the reliability and validity of the model. The system framework can well plan and evaluate the whole lean production level. Accurate assessment of lean production level is an effective way to improve lean levels.
