3.Generation Reliability Analysis. Generation System Reliability

Relaible measurment is the consistency of a set of measurements or of a measuring instrument, often used to describe a test. Reliability is inversely related to random error. The validity of a measurment is how accurate it is. Reliability does not imply validity. That is, a reliable measure is measuring something consistently, but you may not be measuring what you want to be measuring. For example, while there are many reliable tests of specific abilities, not all of them would be valid for predicting, say, job performance. A common example often used to illustrate the difference between reliability and validity in the experimental sciences involves a common bathroom scale. If someone who is 200 pounds steps on a scale 10 times and gets readings of 15, 250, 95, 140, etc., the scale is not reliable. If the scale consistently reads "150", then it is reliable, but not valid. If it reads "200" each time, then the measurement is both reliable and valid. This is what is meant by the statement, "Reliability is

FMECA is a methodology to identify and analyse predicted failure modes of various parts within the assembly or system. It is a technique to resolve potential problems in a system before they occur. It is most widely used reliability analysis technique performed between the conceptual and initial stage of the detailed design phase of the system in order to assure that all the potential failures have been considered and the proper provisions have been made to eliminate these failures. [1] (Ref. system reliability theory,2nd edition, Marvin Rausand) this technique can assist in selecting alternative concept for the same system and also provide

Machine 1 had a reliability of 84%, Machine 2’s reliability was 91%, and Machine 3 had a reliability of 99%. The first possible setup, and ultimately the recommended setup, was to backup Machine 1. This led to an overall reliability of 84%. Backing up Machine 2 only gave a reliability of 82%. Backing up Machine 3 only gave a reliability of 76%. Therefore the recommendation is to backup Machine 1 and increase the reliability to 88%.

Reliability refers to system live time, that is, system is running efficiently most of the time. Availability is the probability that the system is continuously available (usable or accessible) during a time interval.

The reliability of a system can be improved through the introduction of redundancy in the system. Some of the examples of redundancy in the operation are as below:

Information will only have value if customers can access it at the right times. Availability can be affected by system errors, and malicious attacks as well as infrastructure problems. Availability is ensured by maintaining hardware as well as repairing hardware immediately when need arise. A correct functioning operating system should also be maintained in the environment free of software conflicts. Adequate communication bandwidth should also be addressed as well as preventing bottlenecks from occurrence.

A goal of redundant topologies is to eliminate network down time caused by a single point of failure. All networks need redundancy for enhanced reliability. Network reliability is achieved through reliable equipment and network designs that are tolerant to failures and faults. Networks should be designed to reconverge rapidly so that the fault is bypassed.

It helps to have a battery backup system installed on the sump pump to keep it running during a power outage. You could also have a gas powered generator installed at your home to help provide constant power if it were to

Network reliability is the ability of a network to maintain or restore an acceptable level of performance during network failures by application various restoration techniques and prevention of service outages from network failures by applying preventative techniques. (Network Survivability, 2001). Computing the reliability of a network is quite difficult; therefore estimation by means of simulation is a popular choice for determining network reliability.

Power – Backup power sources such as diesel generators act like a personal reserve and kicks in when the main source of power is interrupted.

When power fails and returns over and over sensitive computer equipment, such as hard drives, can begin to fail. Beyond the loss of data is the loss of work. The company is expecting a product at a scheduled time, if the power is out on multiple occasions for long periods, but not long enough for generator to kick in, then there may be days of loss work resulting in slipping of delivery deadlines.

The drastic closure of coal and nuclear power stations has reduced the supply available for the UK consumer, causing a cost crisis. Prices of electricity and gas have increased for most of the last decade, road fuel for most of the past two decades. This has had an impact on industrial and economic growth.Energy prices are projected to remain high or increase for many reasons.The UK output is declining as power stations are being closed and costly measures are put in place to cut carbon emissions . Energy companies are investing large sums of money into renewable energy.

* The emergency energy supply was also shut down, meaning there was no additional energy to run the plant.

Dependability means do things on time. Dependability means well management and coordination with each operation ensuring other process. are reliable, such as delivering right material or information on time, correct foreseeing and planning the facilities, reorder and workforce. It leads to more effective operation. It effectively arranging the facilities, information, material, workforce, money and time to ensure all of them can be available at any time, saves the time to wait or to look for the other substitutes. Dependability arrangement reduces the chance of repeating input resources or some resources leaving unused increasing the cost of maintain or store fee, or labor cost.

Secondly, dependability. Dependability means reliability, that is, how the company are performing and completing their promised service, quality and accuracy within the given set requirements between the company and the customer. Dependability is just as important as a goof first hand impression, because every customer want to know if their supplier is reliable and fulfill the set requirements with satisfaction. Dependability is just as important as the first hand impression, because every customer wants to know that their supplier of what it may be are reliable and give the service agreed including great quality within the given timeframe without compromising on the quality. Dependability includes three elements, which are consistent order cycles, safe delivery and complete delivery. First of all, we talk about consistent order cycles.
