About an Approach to Reliability Calculation of Software and Hardware System
The present article is devoted to the development of reliability evaluation methods for software and hardware systems. It analyses factors influencing the reliability of software and hardware systems of information systems. The authors come to the conclusion that it is not fruitful to consider separately reliability of software and reliability of hardware.
The reliability evaluation of software and hardware systems is based on a model contributing to the presentation of software and hardware system reliability as a result of interrelated elements (software and hardware).
Hardware reliability, software reliability, failure-resistance, repairability, availability.
