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. The next most common cause is the performance of scheduled maintenance or other maintenance not necessarily associated with a critical reliability … A new material may involve exploration of how the material will react over time to its shipping and operating environment. Product quality determines the success with the product. Inherent Availability 5. Maintenance has existed for as long as people have owned things they consider valuable. 2 %() ˘ ˚ ! Reliability, maintainability, and availability (RAM) are three system attributes that are of great interest to systems engineers, logisticians, and users. Using Failure Analysis Simulation Tools To Enhance System Reliability And Streamline Prototyping And Maintenance (Montreal, Quebec) December 3 rd , 2020 Famic Technologies' Sr. As a minimum, new materials or components must be researched to understand the known failure mechanisms and how they manifest within the chosen design and environment. The reliability goal is like any other product specification; it just concerns the performance over time after the product is placed into service. Creating a product that is repairable is part of the design. It aims to achieve a more holistic approach that … We’ve talked around it before. Yes and no. Availability is related to the concept that the equipment is ready to work when expected. The focus may shift to those areas related to the changes and validation of existing failure mechanisms. 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. 4 This column lists each student.

Join over 14,000 maintenance professionals who get monthly CMMS tips, industry news, and updates. Everyone desires products that offer more features, provide higher value, cost less and last longer. The location within the product may alter the temperature the elements experience. Fred Schenkelberg is a leading authority on reliability engineering. and repairable items and reliability measurement of nonrepairable and repairable items. This is especially true for products with a short season for sales (e.g., the holiday market). R&M management requires knowledge of product specifications, apportioning reliability, an understanding of feedback mechanisms and a consideration of maintenance requirements. The maintenance schedule for the 747-100 was the first to apply Reliability Centered Maintenance concepts using MSG-1. And it achieved a 25% to 35% reduction in maintenance costs … If reliability refers to the practices put in place to proactively extend the useful life of an asset, then what does reliability culture entail? Reliability as a business strategy 3. In a series system, the probability of failure for each element is lower than that for the overall system. FMEA is a tool used to merge the ideas and knowledge of a team to explore the weaknesses of a product. He is a Mechanical Engineer (University of Toronto 1977) with over 40 years Reliability, Maintenance … As Industry 4.0 gains steam, so to speak, setting up a reliability-focused culture will only become easier. Setting milestones and deadlines is a management tool that helps get the product to market in a timely and coordinated manner. Careful failure analysis may reveal design weaknesses, poor material choices, or unexpected behavior. Reliability increases the efficiency while redundancy increases the current capability and expectations. The tools and resources of R&M engineering provide a means to efficiently achieve one’s R&M goals. Another approach is to monitor indicators of the amount of wear or damage that has occurred and repair the unit just as that unit’s specific useful life is about reached. Monitoring and maintenance can be very sophisticated or very simple, such as having a brake wear indicator that causes a squealing sound. A highly accelerated life test (HALT) may expose a faulty layout and require a redesign of the printed circuit board. Introduction to reliability Reliability has gained increasing importance in the last few years in manufacturing organisations, the government and civilian communities. Website by Blue Fish. Any production organization sets a goal of achieving production efficiency and ability to operate at an optimum level at all the time. Reliability culture, on the other hand, encompasses everything machinery interacts with: technology, culture, design, and maintenance strategy. Fiix® is a registered trademark of Fiix Inc. There are many metrics related to the time to repair: diagnostic time, spare part acquisition, technician travel time, equipment repair time, etc. Each week we send out an email with the latest tips, white papers, articles, and videos. With recent concern about government spending, agencies are trying to purchase systems with higher reliability and lower maintenance … Discovery may involve a wide range of tests, including material characterization, step stress to failure testing, and highly accelerated life testing. Maintenance crews must be careful to properly restore complex systems to service. One must localize the apportioned goal, or at least provide sufficient information, to fully articulate and act upon an apportioned reliability goal. Collectively, they affect both the utility and the life-cycle costs of a product or system. Copyright © 2020. The combination of the design, the supply chain for spare parts and tools, and the execution of repairs are all part of maintainability. During product development, the design is regularly evaluated or tested and compared to the desired set of functions. It aims to achieve a more holistic approach that addresses the root causes of failures and builds long-term solutions to curb them. Reliability Centered Maintenance and optimization of maintenance programs are Oscar Vasquez’s area of expertise. 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. Best practices 2. This is where a strategy of total productive maintenance (TPM) becomes very useful. The discipline’s first concerns were electronic and mechanical components (Ebeling, 2010). In other words, reliability of a system will be high at its initial state of operation and gradually reduce to its lowest magnitude over time.
