What is the overall efficiency of the equipment?
The overall efficiency of the device (OEE) is an analytical method developed by the Japanese institute for plant maintenance (ICU), which creates transparency to possible losses in production in three categories: availability, performance level and quality rate. As an OEE tool, it brings loss data and also shows the possibilities of improvement that reduces lean production losses to improve operating margins, optimize competitive measures that increase the reputation of the company, and create the quality of the product that allows good investment return. Using metrics that indicate production efficiency, they can provide comparative values across different types of production and products to process not only what improvement should be done, but also how much improvements will help on the lower line.
Measurement and analysis of conventional machines and processes, OEE points to the maximum efficient use of current operations and can be against investments in multiple machines. Making changes in howThe current device is used, can remove narrow places, give excessive capacity to use and prevent loss of downtime. The overall analysis of the efficiency of the equipment is valuable in reducing seemingly complex production problems on simple, informative presentations of possibilities to improve every process of operation. It effectively inserts into the hands of the measurement management they need to manage, and together with other slim manufacturing programs can reduce waste in many areas and, as a result, produce a higher quality product.
The first of the three categories, availability, is reliable availability of planned production 24 hours a day, seven days a week and 365 days a year. This metric is a time that is due to the loss of downtime and its formula is availability that is equal to the opening hours divided by planned production time. Starting in obvious positions in narrow locations in line or narrow devices can the total efficiency of the device detectionT metrics that can be compared to the same or similar machine and examine their maintenance records, apply multiple support systems to the machine or increase its frequency of general revisions.
The second category is the performance rate. This factor represents the running speed of the production center as a percentage of its proposed speed. It takes into account the loss of speed and its formula calculates as a performance that equals the pieces produced by the ideal ideal cycle divided by the available time. In this calculation, the ideal cycle time is a minimum time that can be expected to achieve the process and the performance is limited to a full 100 percent. If the planned breaks of operators leave the inactivity of the machines, it may be a recommendation that the breaks could be distributed and the employees mix so that no machine is ever idle.
The third and the finals of the three -racer overall efficiency are the quality of the quality, the number of good units produced from the total units began in production. This is a return forCESU and here the sensitivity analysis can point out the measures of the recommended changes. The quality of the product can be an opportunity for the greatest return on the asset, so improving the share of good units and reducing rejection can improve the lower limit and reputation of the company.
