The operating plan collects the case process information and preliminarily plots the current status of the production line based on the VSM principle, in order to facilitate the review and use of OEE for sub-item statistics, to calculate the overall efficiency of the equipment as the basis for improvement; according to the Plato analysis method for the main bad The effi-ciency loss caused by the factors, and the related events of equipment non-availability efficiency are classified into the relationship between the working time and the waiting time, and then the problem is determined through PDCA, and the improvement method is determined accordingly, and the efficiency of the equipment is improved to improve the overall OEE efficiency. Improvement. Improvements in the original OEE performance through equipment have im-proved performance by more than 10%, while VSM observed the overall improve-ment of the whole plant, the production lead time was shortened from 143 minutes to 115 minutes, the improvement rate was 19.580%; The cycle time 48.94 seconds was shortened to 46.42 seconds, and the improvement was 5.150%. The WIP was re-duced from 993 pcs to 515 pcs, with an improvement of 48.137%. Keyword: OEE, VSM, PDCA, Pareto
