The set of product functions or features defines the operating state and, conversely, what a system failure may include. Creating a product that is repairable is part of the design. The fundamental expectation from a customer’s point of view is for the product to work as promised. Concepts of throughput, capacity and readiness are related to availability. Fred has a Bachelor of Science in Physics from the United States Military Academy and a Master of Science in Statistics from Stanford University. Monitoring and maintenance can be very sophisticated or very simple, such as having a brake wear indicator that causes a squealing sound. The discipline’s first concerns were electronic and mechanical components (Ebeling, 2010). The difference may require changing the design or adjusting the goal. Like functions and costs, shipping a product on time is routinely measured. For example, in the calculation of the Overall Equipment Effectiveness (OEE) introduced by Nakajima [], it is necessary to estimate a crucial parameter called availability.This is strictly related to reliability. This also puts the onus on operators to make sure their asset is running as expected, and that any future preventable breakdowns can be addressed and stymied. These four aspects drive the development of any product. For example, periodically testing an oil sample may reveal when the oil is about to become ineffective as a lubricant. Your maintenance should too. For the team maintaining equipment, considerations include understanding equipment failure mechanisms, symptoms and MTTF expectations. Any production organization sets a goal of achieving production efficiency and ability to operate at an optimum level at all the time. For example, a car’s oil filter has standard fittings, permitting the use of existing oil filters as a replacement. HALT is a discovery tool in which sufficient stress or multiple stresses are applied to a product to cause failure. The origins of contemporary reliability engineering can be traced to World War II. By using specific approaches and tools, one can obtain optimized, cost-effective solutions to the design, assembly and use of a product. Performance of product is determined by the reliability and redundancy. Reliability and maintainability management is the management of failure. As a reminder, TPM embraces the philosophy that everyone in a facility should be responsible for maintenance. Using Failure Analysis Simulation Tools To Enhance System Reliability And Streamline Prototyping And Maintenance (Montreal, Quebec) December 3 rd , 2020 Famic Technologies' Sr. Creating a work culture to set your CMMS implementation up for success, Exploring the undeniable link between asset management and sustainability. The opposite is true for elements in parallel. Modern products may have hundreds of materials and thousands of components, yet each has some failure mechanism history of exploration and characterization. Discovery may involve a wide range of tests, including material characterization, step stress to failure testing, and highly accelerated life testing. Steady State Availability 4. Ready to start your reliability journey? The intent is to find the weaknesses within a design and take steps to minimize failures. It also works closely with operations to ensure that the equipment is … Average Uptime Availability (or Mean Availability) 3. These four aspects drive the development of any product. And it achieved a 25% to 35% reduction in maintenance costs … Researchers should be engaged in a discussion about how the material may behave in the chosen design. Maintenance has traditionally functioned as a one to one, technical relationship with equipment, where something is fixed when it breaks. Understanding and characterizing the failure mechanisms enable the designer to avoid surprises in later product testing or during use. The failures provide knowledge on areas for improvement. and repairable items and reliability measurement of nonrepairable and repairable items. 1. Reliability follows an exponential failure law, which means that it reduces as the time duration considered for reliability calculations elapses. © 2020 Reliabilityweb.com | Terms of Service | Privacy Policy | Trademark and Copyright | About Us | Advertise on Reliabilityweb.com | Steal These Graphics A product that has its detected weaknesses resolved is more robust and, thus, able to withstand normal stresses and the occasional abnormal stress load without failure. Reliability is the probability of a product successfully functioning as expected for a specific duration within a specified environment. This research is focused on the latter. Best practices 2. Maintenance crews must be careful to properly restore complex systems to service. For example, the power supply may operate full time, but the hard drive may often be idle and partially powered down. The team may require specialized training and certifications; these also may increase maintenance costs. He is a troubleshooter and an expert in sales and business development in Latin America, … FMS Reliability, Free eBook: 11 Problems With Your RCA Process and How to Fix Them, The Reliability & Maintenance Manager’s Complete Guide to Asset Strategy Management, Join The Association of Asset Management Professionals, Upcoming 2020 - Reliabilityweb.com Certified Reliability Leader Workshops, Upcoming 2020 - Reliabilityweb.com Certified Maintenance Manager Workshops, 2021 - Reliabilityweb.com Certified Maintenance Manager (CMM) Workshops, 2021 - Reliabilityweb.com Certified Reliability Leader Workshops. Prognostic health management is a relatively new field focused on measurement techniques that, like the wear indicator in brake pads, assist the maintenance team in maximizing the useful life of a product and effecting repairs and maintenance only as needed to prevent failure. The relays also compute line megawatt and megavar flows that can be read on a front panel display, and the computations … The reliability of your systems, services and products has a direct impact on your success. Both require some knowledge about the failure mechanism involved to set the triggering time or event criteria so the maintenance is performed before either significant damage to the system or failure occurs. Depending on the team and amount of knowledge already known, FMEA may or may not be a fruitful tool to discover product failures. Product quality determines the success with the product. Larger projects, like implementing a CMMS, formalizing a TPM mission and vision, and performing reliability audits, will help keep reliability at the forefront of everyone’s mind. Reliability is the probability that a system performs correctly during a specific time duration. It aims to achieve a more holistic approach that addresses the root causes of failures and builds long-term solutions to curb them. All Rights Reserved, A look at the tools that empower your maintenance team, Manage maintenance from anywhere, at any time, Track, control, and optimize asset performance, Simplify the way you create, complete, and record work, Connect your CMMS and share data across any system, Collect, analyze, and act on maintenance data, Make sure you have the right parts at the right time, AI for maintenance. Maintenance computations is important because keeping a detailed record of all the maintenance and repairs that a piece of equipment went through will help increase its resale value. Collectively, they affect both the utility and the life-cycle costs of a product or system. Cost may or m… Fiix® is a registered trademark of Fiix Inc. reliability failure and the subsequent maintenance and logistics delays associated with restoring the item to an operational state. Maintenance has traditionally functioned as a one to one, technical relationship with equipment, where something is fixed when it breaks. Their articles on site reliability are some of the most informative and reliable available, and they make appropriate site reliability training resources, especially because they are available from any device with a web browser at any time. Introduction to reliability Reliability has gained increasing importance in the last few years in manufacturing organisations, the government and civilian communities. These aspects will be addressed in turn. Get your blueprint for building the maintenance team of tomorrow, today. Buyers thoroughly … Last year, we defined reliability cultureas “the overall cultural shift that’s required for an organization to fully understand the big picture when it comes to asset reliability.” More recently, we talked about the difference between maintenance and reliability, noting that reliability is a much more holistic, long-term approach to asset management than maintenance.
