In any process automation & control industry, the most widely used control algorithm is proportional-integral-derivative (PID), according to National Instruments. PID control has been widely adopted throughout industrial control markets, dating back to the beginning of trying to optimize any process.
Reliability engineering is about predicting failures and providing ground for decision-making related to preventive maintenance optimization (PMO), lifecycle costing, spare parts forecasting, and reliability, availability and maintainability (RAM) modeling. Different tools are available to the reliability engineer for such levels of predictions. The benefit of these tools comes from proper planning and management plans to cope with future issues.
Many Americans believe that American manufacturing is a relic of the past, rusting abandoned profession where weary men and women drudge through the day performing a single task for hours on end.
Organizations that aggressively pursue operational excellence have the best opportunity for enhanced profitability. They also realize value provided from a purpose-built computerized maintenance management system (CMMS), precisely configured to extract knowledge and manage by exception. However, the CMMS is only as good as the surrounding process and roles. Hence, a comprehensive plan is needed that encompasses the entire asset management system to enhance reliability, workforce productivity and job safety.

It’s a quiet December afternoon in 2015. In the Ivano-Frankivsk region of Western Ukraine, workers are preparing to finish their day and make their way home into a cold night. Inside the Prykarpattyaoblenergo control center, which distributes power to the region’s residents, operators are nearing the end of their shift. Suddenly, an unprecedented series of cyberattacks takes place as they watch in amazement. The attacks eventually knock out parts of Ukraine’s electric grid, thus cutting the power to nearly a quarter of a million residences.
The evolution of OT is meteoric. Today, a proliferation of connected devices can monitor asset condition and performance, along with operational conditions. The information captured from these devices enables operational optimization. It can also prevent unplanned downtime through early detection of impending failures, allowing corrective actions to be planned.
It is disappointing when reliability-centered maintenance (RCM) studies are performed on a critical system, yet weeks roll on and then years go by without implementing the needed changes into the computerized maintenance management system (CMMS).
The May 2019 The RELIABILITY Conference™ saw a significant increase in the number of sessions and vendors that included the Internet of Things (IoT), Industry 4.0, or digitization topics/themes. The IoT related content has been on a steady rise for the past couple of years, with no sign of slowing down as evidenced by the agendas for the MaximoWorld 2019 and IMC-2019 conferences in August and December 2019, respectively. Of course, if you are in the business of maintenance reliability, this subject prevalence is nothing new to you.
Part 1 in the June/July 2019 Uptime issue closed with the experience-based statement that failure risk can escalate by certain specification practices, including some contained in API 610. Without going into the many possible reasons for bearing life reductions, the quest for better bearings in upgraded process pumps elicits several observations that should be considered when preparing a modern pump specification.
Southern Gardens has embarked on a journey in pursuit of achieving excellence in reliability. The key is perseverance because the road is often bumpy. Continuous improvement moves you down the continuum, so when you think you are at the end, you realize there is always room for improvement.
[St. Louis, MO, July 18, 2019] How to Add Building Envelope Inspections to a Maintenance Program. Building inspections don’t seem to get the respect they deserve, as people often think they’re a waste of time or are unnecessary. Maybe it’s because inspections are usually used to find small problems, and people don’t want to take the time to look for problems where there appear to be none. That is exactly why building inspections are so powerful.
Addressing defect elimination with common sense. But is it this simple? Ron Moore, author of "A Common Sense Approach to Defect Elimination," discusses all this and more.
