Research on process optimization for equipment maintenance based on lean six sigma management

In order to optimize the process of equipment maintenance and improve the maintenance efficiency effectively, by the four steps of choosing the method of DOE, fitting the model, analyzing the residual and optimizing the result, equipment maintenance process optimization model method under equipment maintenance lean six sigma project is established based on design of experiment (DOE). Via taking a certain equipment maintenance technique parameters optimization as an illustrative example, the optimization model which can provide a new method for the optimizing of equipment maintenance process in lean six sigma project is proved to be scientific, valid, and well applicable finally.
