Essential Manufacturing Metrics that Promote Efficiency

 Even if there are a million things we might say about business, it is ultimately just a numbers game. Essentially, profit and loss figures determine everything in a corporation. Data like revenue earned, orders filled, and other similar information are very important in the company. A business may use some key performance indicators as its guiding measures. The accurate evaluation of those indicators is crucial for the proper operation of a corporation.

OEE (Overall Equipment Effectiveness) tracking is a performance metric used in manufacturing to measure the efficiency of equipment and identify areas for improvement. OEE is calculated by multiplying three factors together: Availability, Performance, and Quality.

Availability measures the percentage of time the equipment is available for production. This includes planned downtime (such as maintenance or cleaning) and unplanned downtime (such as breakdowns or changeovers).

Performance measures the actual production rate of the equipment compared to its theoretical maximum output rate. This takes into account factors such as speed losses, idling time, and minor stops.

Quality measures the percentage of good quality products produced by the equipment compared to the total number of products produced. This includes any rework or scrap that may have been generated during the production process.

By tracking OEE, manufacturers can identify areas where improvements can be made to increase efficiency and productivity. For example, if the availability of the equipment is low, it may indicate that more frequent maintenance is needed, or that the equipment needs to be replaced. If the quality is low, it may indicate that adjustments need to be made to the production process to reduce waste or improve product quality.

OEE tracking can be done manually using spreadsheets or with specialized software that automatically collects and analyzes data from production equipment.

Overall Equipment Effectiveness (OEE): OEE measures the efficiency of equipment by taking into account availability, performance, and quality. By monitoring OEE, manufacturers can identify areas where improvements can be made to increase efficiency and productivity.

Cycle Time: Cycle time measures the time it takes to produce a product from start to finish. By reducing cycle time, manufacturers can increase throughput and reduce lead times, which can lead to improved customer satisfaction and increased profitability.


Yield: Yield measures the percentage of products that meet quality standards. By improving yield, manufacturers can reduce waste and improve product quality, which can lead to increased customer satisfaction and profitability.


Downtime: Downtime measures the amount of time that equipment is not available for production. By reducing downtime, manufacturers can increase the availability of equipment and increase productivity.

Capacity Utilization: Capacity utilization measures the percentage of a plant's total capacity that is actually being used. By maximizing capacity utilization, manufacturers can increase productivity and reduce costs.


Inventory Turns: Inventory turns to measure how quickly inventory is sold and replenished. By increasing inventory turns, manufacturers can reduce inventory carrying costs and improve cash flow.

The New OEE Impact Andon Boards for Spare Manufacturing System

Image
Andon can be defined as" visual control" device that shows machine, process status or line. Utmost spare manufacturing systems need this device as it's veritably useful to reduce product waste in all situations. By using andon boards, a company can cover and insure productivity fluently. Manufacturing storehouse use this tool to see order status or precedences in an instant way indeed from further than 100 bases down. This device can also serve as early warning bias since audible admonitions or advising dispatches are installed in the device. In short, it can be said that this communication tool leads to a better collaboration of orders, precedences and corridor in a spare manufacturing system. This good collaboration eventually leads to a better client service .    The use of andon boards replaces the part of traditional communication tool in spare manufacturing systems . With this device, now a company does not need to use clip boards, white boards or emails to communic

OEE Systems That Drive Down Manufacturing Costs Using Existing Resources

With the economic climate still skirting around on the edge of recession , and more recent talk of a further drop, many manufacturing businesses are approaching crisis levels. In an effort to stay afloat , competition amongst rivals is becoming stronger, and the need to cut costs whilst maintaining quality , and using existing levels of resource, has never been stronger. The new OEE ( Overall Equipment Effectiveness ) software systems, play a significant role in optimizing manufacturing production efficiency using the same plant resource . This has fuelled significant interest from many manufacturers , and is rapidly being adopted as the tool of first choice to improve the cost v profit ratio . Companies that employ OEE systems in their most simple form are able to monitor how efficiently their plant is performing in terms of throughput and contribution to sales. But that is only scratching the surface in terms of what the real power is when it comes down to seeking and implemen

System improvements are brought about by the new Design for OEE methodology.

  If your firm uses automation to increase productivity , as most businesses do, OEE is a crucial statistic for evaluating where improvement efforts should be directed. All three OEE components —Availability, Performance, and Quality—apply if most of your production stages involve manufacturing machinery.   The component results have averaged 90%, 86%, and 98.7%, respectively, for the firms I have tracked and following some improvement attempts. The OEE for this is 76.4%. OEE of 85% is typically used as a world-class benchmark by enterprises . Even this standard for excellence can be surpassed with a change in emphasis regarding where improvements are made.   Most Lean Six Sigma practitioners have seen the cost and quality advantages of DFSS in the New Product Introduction process. Design For Overall Equipment Effectiveness , or DFOEE, is something I would want to propose that is similar and equally as advantageous. I agree that the DFSS technique may be used for machine design, an
