Good products seek to minimize the unexpected interruptions in performance throughout the duration of the typical of customer experience. Notify management of upcoming inspections and recommendations, deficiencies in processes, and corrective actions. If the equipment has already been purchased, the inherent reliability is fixed but you can still impact the operational reliability and life cycle costs. These are reliability-wise in series and a failure of any of these subsystems will cause a system failure. How does that engineer prioritize the work? If you think about how we use the word “reliable” in everyday language, you might get a hint. Most computer equipment therefore has some form of cooling, ranging from a simple fan to forced chilled air cooling. High equipment reliability is a choice and not an accident of fortune. The largest contributors are recognized as critical assets and specific performance targets are identified. The probability that a PC in a store is up and running for eight hours without crashing is 99%; this is referred as reliability. 2 Introduction 3. Availability, also known as operational availability, is expressed as the percentage of time that an asset is operating compared to its total scheduled operation time. The definition that follows is the definition that I prefer; it is one that has been derived from many definitions that I have seen over time:“The Should apply different techniques like Fault Tree Analysis, Weibull Tree Analysis, Six Sigma Methodology, Root Cause Analysis and Statistical Process Control for developing engineering solutions to repetitive failures. Equipment reliability is measured in terms of quality, performance, and productivity. The probability of an injury is significantly increased with non-routine maintenance activity resulting from equipment failures.

It is most often expressed as a percentage, using the following calculation: Availability = 100 x (Available Time (hours) / Total Time (hours)) For equipment and/or systems that are expected to be able to be operated 24 hours per day, 7 days per week, Total Time is usually defined as being 24 hours/day, 7 days/week (in other words 8,760 hours per year). Reliability engineers call these parallel systems. What is the role of an Equipment Reliability Engineer? 4 Equipment Reliability Training Series Learning Objectives (Continued) 7. 2. To develop and promote excellence in maintenance, reliability and physical asset management. What is Reliability? 4. 2. To a great extent you can choose how long you want between equipment failures. However, it does include explanations of some statistics commonly used to describe test reliability. When the equipment does what it needs to do when it needs to do it, plant output and profitability is maximized. Advantages of a reliability program include eliminating unexpected shutdowns, reducing production losses … Reliability Testing can be categorized into three segments, 1. We can refine these definitions by considering the desired performance standards. We use the term “production reliability” to lay the foundation for the vital partnership between operations and maintenance. Reliability Testing. Develop and maintain the Risk Management Plan for identifying and managing all risks. We focus on three major areas: Energy efficiency, Maintenance Cost and Equipment Reliability. We’ve talked around it before. The goal of an equipment reliability program is to effectively monitor equipment, procedures, and data covering the life of equipment. This application of “guessing” as the primary tool for root cause analysis of equipment reliability and maintenance problems is probably the biggest challenge to achieving equipment reliability excellence. Prerequisite Knowledge . Let’s explore the distinction between reliability and availability, then move into how both are calculated. Every manufacturing facility wants production equipment to operate reliably. A Reliability Engineer must manage and access the overall risk to achieve the strategic goals of an organization. Measuring Reliability. Some of the highly accurate balances can give false results if they are not placed upon a completely level surface, so this calibration process is the best way to avoid this. This shows the need for the Reliability Engineer to participate in project design and installation phases for new resources and current asset alteration. Our technologically based society depends on machinery and equipment to keep it operating. The Becht Equipment Reliability Planning (ERP) Work Process brings together all these parts of an organization to achieve holistic reliability, safety and profit goals. Another major trend indicator is the financial KPI of Maintenance Cost per unit Production. The probability of an injury is significantly increased with non-routine maintenance activity resulting from equipment failures. Develop and monitor an Asset Maintenance Plan for effective utilization of strategies and designed for identifying and isolating reliability problems. These losses are prioritized to focus efforts on the largest/most critical opportunities. Only when it is clearly understood that achieving a high level of equipment reliability … Reliability describes the ability of a system or component to function under stated conditions for a specified period of time. The reliability of the system is the probability that unit 1 succeeds and unit 2 succeeds and all of the other units in the system succeed. Reviewing performance and adjusting the maintenance strategy. The first key area where Maintenance can impact on equipment reliability is by having an appropriate preventive and predictive maintenance program in place. Step 1: Selection of equipment for RCM analysis. Alternatively, availability can be defined as the duration of time that a plant or a particular equipment is able to perform its intended task.

Reliability … Availability refers to the duration of time that a plant or a particular equipment is able to perform its intended task. The Equipment Reliability Process focuses the maintenance of physical asset reliability on the business goals of the company. 1 EQUIPMENT RELIABILITY TRAINING SERIES LEVEL 1: AWARENESS 2. Inventory Turns. A reliability engineer is an individual responsible for tracking the equipment behavior to avoid any downtime that may affect company revenues. Root Cause Analysis is a critical part of your equipment reliability program. Reliability follows an exponential failure law, which means that it reduces as the time duration considered for reliability calculations elapses. Simple parallel system – the system reliability is increased to 99% due to the redundancy. While a reliability engineer’s role differs from company to company, their objective is always the same: to minimize equipment downtime, lower maintenance cost, and to avoid business operations interruption. The block diagram for a simple two component parallel system is shown in Figure 10. 1.5 The analyses presented in this document are designed to identify deficiencies in equipment support resources as well as in the equipment itself. How do you accurately go about determining equipment reliability? Accept Failures. In the non-physical sciences, the definition of an instrument is much broader, encompassing everything from a set of survey questions to an intelligence test. There is a generally accepted availability standard of 95 percent for equipment, but mission- critical equipment in facilities requires a much higher level of availability. What is reliability? In other words, all of the units in a series system must succeed for the system to succeed. We hear the term used a lot in research contexts, but what does it really mean? Our reliability engineers experts evaluate your plant mainteance program maturity,  and  develop a strategies to achieve short, middle and long terms benefits using proven world-class best practices. This step is performed in collaboration with the production process. ERPs also comply with API RP-580 – Risk Based Inspection for fixed equipment and piping. Having fully reliable equipment is a pre-requisite for meeting customer demand, on-time. You can deliver high equipment reliability by ensuring the chance of incidents that cause failures Effects are how such errors can result in faults or damaging results. That’s what TPM does. Failure modes are how a process can fail. Troubleshooting IS NOT Root Cause Analysis. Imagine being a maintenance engineer and receiving 50 work orders during an overhaul with a limited budget, time, labor, spare parts, tools, machines, etc. The equipment selected should be critical in terms of its effect on operations, its previous costs of repair, and previous costs of preventive maintenance. And, reliability increases stakeholder value. The final result of an RCM program is the implementation of a specific maintenance strategy on each of the assets of the facility. Studies indicate that up to 95% of an asset’s Total Ownership Cost (TCO) or Life Cycle Cost (LCC) is determined before it is used. The analysis also provides useful information to determine what measures will decrease the risk for all plant assets. Simple. often affects its interrater reliability. Improved equipment reliability can reduce maintenance costs, minimize opportunity costs associated with downtime, and can ensure products are not produced outside of acceptable specifications. That’s why it is our belief that the overall competitiveness of your organization depends on establishing stable and reliable processes and equipment.
