The distributed system is a paradigm in which the components can communicate by means of the interface connected between them. The interaction between the components takes place in order to achieve a common goal. The reliability metrics is used to evaluate the performance of the components which is connected by the distributed systems. The Mean Time Between Failure (MTBF), Mean Time to Repair (...

Increasing MTTF requires increasing reliability. In previous lectures we saw a variety of ways to do so: testing, static analysis, formal methods, etc. A highly reliable system is a highly available system. Reducing MTTR requires reducing the (mean) time it takes for the system to come back up once a failure has occurred. Once a failure occurs, we must detect it, diagnose it, and the recover th...

The purpose of this research was to design and develop a machine Smart Machine Health Monitoring device (SMHM) for traditional manufacturing units based on the industry 4.0 (I4.0) concept. tool performance has been demonstrated using metrics such as overall equipment effectiveness (OEE), mean time between failure (MTBF), (MTTF). rejection rate unscheduled downtime were reduced by 68.04 percent ...

The article analyzes the operational reliability of filter on gas turbine compressor intake and electric transformer connector. Empirical data (statistical sample) were collected to determine failure density function f (t), hazard λ expected value mean time MTTF. numerical model was created in Minitab 19 software tool. Anderson-Darling test used accept or reject hypothesis.

Making the correct maintenance strategy decision for industrial multistage machines (MSTM) is a constant challenge manufacturers. Preventive strategies are most popular and provide interesting results but cannot prevent unexpected failures consequences, such as time lost production (TLP). In these cases, predictive should be used to maintain appropriate level of operation time. This research ai...

Starting with the meaning of the word quality, diverse concepts connoted by the term are examined. Instead of a bathtub curve, the desirable shape of a failure rate covering the entire life of a good product, which might be called hockey-stick line, is introduced. From the hockey-stick line and the definition of reliability, two measurements are extracted. The terms r-reliability (failure rate)...

With the effect of increasing production rate, probability shifting manufacturing process from “in-control” state to “out-of-control” increases with passage time. This happens due degradation mechanism which results in defective items. study helps examining changed rate on quality goods produced. research further examines influence “mean time failure (MTTF)”. increased is not always environment...

Disk arrays (RAID) have been proposed as a possible approach to solving the emerging I/O bottleneck problem. The performance of a RAID system when all disks are operational and the MTTF,,, (mean time to system failure) have been well studied. However, the performance of disk arrays in the presence of failed disks has not received much attention. The same techniques that provide the storage effi...

This paper emphasizes that instead of long-term availability and reliability, the short-term session durability analysis will greatly impact the design of the real large-scale Peer-to-Peer storage system. In this paper, we use a Markov chain to model the session durability, and then derive the session durability probability distribution. Subsequently, we show the difference between our analysis...
