2014-7-21The objective of this post is to bring clarity in understanding the two often confused terms viz Availability and Reliability by explaining in simple perspective for the purpose of understanding by a common maintenance man Let's try to understand through this picture This is the time-line of a particular Equipment where U is Operating time (Uptime in Hrs) D is Repair time (Downtime in
2020-8-19Reliability testing will be performed at several levels Complex systems will be tested at unit assembly subsystem and system levels Why to do Reliability Testing Reliability testing is done to test the software performance under the given conditions The objective behind performing reliability testing are To find the structure of repeating
Instrument reliability is a way of ensuring that any instrument used for measuring experimental variables gives the same results every time : In the physical sciences the term is self-explanatory and it is a matter of making sure that every piece of hardware from a mass spectrometer to a set of weighing scales is properly calibrated
2019-7-31If you do not directly track Good Count it also needs to be calculated Formula: Total Count − Reject Count Example: 19 271 widgets − 423 widgets = 18 848 widgets Availability Availability is the first of the three OEE factors to be calculated It accounts for when the process is not running (both Unplanned Stops and Planned Stops)

2020-8-16Machines: Any equipment tools etc needed to do the job Materials: Consumables parts required Measurements: Data generated from the process All of these items combine together to create some output or event In the case of maintenance planning and scheduling hopefully they combine to maintain or restore the reliability of equipment as
2011-3-15reliability based on operation of equipment over time Prediction methods are based on component data from a variety of sources: failure analysis life test data and device physics For our calculations MIL-HDBK-217 is used which is considered to be the standard reliability prediction method

2015-12-23You have to deeply want the production and profit benefits equipment reliability brings before you will do what is necessary to get it If you want plant and equipment to operate trouble-free for a long time you must do those activities that cause reliability and do them well enough to deliver reliability

2019-6-26Cause #2: Failure to perform preventive maintenance Most equipment requires regular maintenance for optimal performance but too often preventive maintenance is the first task to go when you're short-staffed and overwhelmed It's easy to brush off regular maintenance when things seem to be running just fine and many companies work under the assumption that experienced workers will
When you see a question that seems very similar to another test question it may indicate that the two questions are being used to gauge reliability Because the two questions are similar and designed to measure the same thing the test taker should answer both questions the same which would indicate that the test has internal consistency
You must know where you are and where you want to go or you may not recognize it when you get there "Distinguish Management Data and Reporting Information" Budget performance Annual budgets of anticipated reliability activities should be estimated for each equipment item or asset each year and continuously monitored
Before diving into the reliability program key elements we must understand the meaning of equipment reliability What is Equipment Reliability? Is the probability that an asset item or unit will perform its prescribed duty without failure for a given time in a specified environment
The primary role of the Reliability Engineer is to identify and manage asset reliability risks that could adversely affect plant or business operations This broad primary role can be divided into three smaller more manageable roles: Loss Elimination Risk Management and Life Cycle Asset Management (LCAM)
The Certified Maintenance Reliability Professional (CMRP) program is the leading credential for certifying the knowledge skills and abilities of maintenance reliability and physical asset management professionals Equipment Reliability Manufacturing Process Reliability Organization Leadership and Work Management Eligibility The
2020-8-19People often confuse reliability and availability Simply put availability is a measure of the % of time the equipment is in an operable state while reliability is a measure of how long the item performs its intended function We can refine these definitions by considering the desired performance standards
Set Up an Equipment Reliability Database Recording all pump-related information in a central location makes spotting trends and recurring equipment issues easier Many vendors offer proprietary database programs to help monitor pump reliability or end users can establish their own databases
Reliability is a measure of the consistency of a metric or a method Every metric or method we use including things like methods for uncovering usability problems in an interface and expert judgment must be assessed for reliability In fact before you can establish validity you need to establish reliability Here are the four most common ways of measuring reliability for any empirical

2020-8-17Many equipment reliability processs fail simply because the managers and practitioners don't have confidence that it can deliver the required results Failure Mode: Lack of Accountability These days we hear much about empowerment self-direction This sometimes leads to the idea that everyone can do their own thing as long as they do those
Test-Retest Reliability and Confounding Factors To give an element of quantification to the test-retest reliability statistical tests factor this into the analysis and generate a number between zero and one with 1 being a perfect correlation between the test and the retest Perfection is impossible and most researchers accept a lower level either 0 7 0 8 or 0 9 depending upon the
Reliability engineers are responsible for identifying and managing asset reliability risks that could adversely affect a plant or business's operations They utilize principles of math science and engineering to make industrial manufacturing and production processes and products more efficient and dependable
I have created an Excel spreadsheet to automatically calculate split-half reliability with Spearman-Brown adjustment KR-20 KR-21 and Cronbach's alpha The reliability estimates are incorrect if you have missing data KRl-20 and KR-21 only work when data are entered as 0 and 1 Split-hal
2020-8-19The downtime that is associated with equipment failures will depend both on the equipment reliability (the number of equipment failure events) and the length of time that it takes to restore the functionality of the equipment each time one of these events occurs
