"Structural Reliability of Information Systems", 2012

The book presents the basic concepts and parameters of information systems’ structural reliability. It shows generality and specific differences in reliability indices used in domestic and international standards. The recent changes in approaches to reliability modeling are reflected. Markov models of reliability together with graph semi-Markov methods for reliability calculating which are illustrated by numerous examples are described in detail. Considerable attention is paid to the engineering methods of calculation and the approximate prediction of information systems’ structural reliability, error estimation, as well as to statistical assessment of reliability parameters. At the end of each chapter, there are checklists for the most complex and significant content of the chapter. The book is intended primarily for professionals involved in practical work on development, production, operation and modification of information systems. It is designed to scientists in the field of structural reliability of various discrete systems, academic staff, graduates (students) specializing in information systems, as well as in the field of automated control systems.

«Reliable Fail-safe Information Systems. Methods of synthesis», 2016.

The book describes conceptual provisions to ensure structural and functional reliability of information systems at all stages of a life-cycle. It represents different types of redundancy taking into account limited efficiency of the failure detection system. Under these conditions a broad-based assessment of their efficiency is performed, with determination of capabilities of structural redundancy with an endless number of standby facilities. Ways to ensure functional reliability of software are represented, including the recommendations for the development of software programs requirement specification, with the description of the process of a reliable program architecture development and well proven rules and recommendations used for design and implementation of software, as well as for integration with system hardware.

The book also presents theoretical and practical provisions of adaptive fault tolerance (active protection) of information systems, including the methods and disciplines of active protection, as well as the ways of implementation. A method of synthesis of active protection and the results of research of information system reliability with various disciplines of active protection are offered. There are also certain assessments of the efficiency of active protection in relation to the traditional methods of structural redundancy.

You can find the description of the principles to ensure functional safety of information systems, with a substantiation of the possibility to restart independent channels in two-channel safe systems. The rules of determination of the allowed time for a guaranteed detection of single and double hazardous failures are developed, including the method of synthesis of a combined two-level information system developed with higher functional safety requirements.

To prove the conformance of reliability with functional safety the method of accelerated field testing of the information system has been developed. The book contains the description of this method, including the example of its practical implementation. You will also find the information about the procedures of certification tests based on the requirements of information safety and software certification conformance.

A checklist of the most complex and significant subjects is provided at the end of each chapter. The book is primarily intended for experts who are engaged in practical development, manufacture, operation and updating of information. It is intended for researchers in the field of structural reliability of different discrete systems, academic staff, post-graduate students and students specializing in the field of information systems and as well as those working in the field of automated control systems.
