Technical systems are in general not guaranteed to work correctly. They are more or less reliable. One main problem for technical systems is the computation of the reliability of a system as studied in reliability theory. A second main problem for technical systems is the problem of diagnostic, i.e. explanations why something does not work. In fact, these problems are — in some sense — dual to ...

with the development of restructured power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benef...

The reliability of locomotive diesel engines largely depends on a timely and objective assessment the technical condition its equipment during operation. article proposes technique for integral state quality working process in cylinder using on-board diagnostics.

Usage profiles and component reliability are two important factors in software system reliability estimation. To assess the sensitivity of a system’s reliability to the usage profile and to the reliability of its components, a Markov based system model is used. With the help of this model, the maximum sensitivity to one change or the statistical sensitivity to many independent changes can be es...

In order to make system reliable, it should inhibit guarantee for basic service, data flow, composition of services, and the complete workflow. In service-oriented architecture (SOA), the entire software system consists of an interacting group of autonomous services. Some soft computing approaches have been developed for estimating the reliability of service oriented systems (SOSs). Still much ...

This paper studies preventive maintenance (PM) in simultaneously considering three actions, mechanical service, repair and replacement for a multi-components system based on availability. Mechanical service denotes the activities including lubricating, cleaning, checking and adjusting, etc. which is set to alleviate strength degradation. Repair is defined on that not only slow down the degraded...

It has been established that the software reliability concept has many specific features and differs significantly from the concept of reliability of technical systems. This greatly complicates the task of assessing overall reliability of a complex software product. The paper introduces a new reliability indicator—average reliability—as well as a method to assess average reliability of a comple...

Correctly measuring the reliability and availability of a cloud-based system is critical for evaluating its system performance. Due to the promised high reliability of physical facilities provided for cloud services, software faults have become one of the major factors for the failures of cloud-based systems. In this paper, we focus on the software aging phenomenon where system performance may ...
