reliability

Hardware/software systems provide flexible implementation of microprocessors, microcontrollers and various peripheral devices and supply the ability to perform almost any functional algorithm that can be simply modified or replaced. For reliability estimation of hardware/software systems we must take into account not only the loss of efficiency, which was caused by the hardware failures, but the abnormal functioning, that was caused by software failures. All these features of hardware/software systems must be considered in their models for reliability indexes estimation.

A brief analytical overview of the structural reliability theory. Analysis of the development of the theory in the framework of adaptation in Ukraine Eurocode package of normative documents and preparation of national annexes carried out.

The method of coefficient approximation of information objects domain ontologies reliability is proposed in the article. This method is based on polynomial splines. It makes it possible to remove unnecessary ontology objects that possess the reliability limit below a certain pre-specified point.

This paper describes an algorithm and software implementation of improved reliability model of technical redundant system with a limited number of restorations. The correlation between the number of elements, the number of their restorations and the number of states of the system, time required for their formation, and calculations of results were investigated
