A Coefficient Method for Calculating the Reliability of Functional Part of Power Supply Pcb 56_14.pdf

The reliability of electronic equipment has been the focus of the attention for many decades. The actuality of that grows along with the miniaturization of electronic components and the density of attachment in electronic equipment. The process of reliability calculation becomes more complex and takes more time in view of the growth of type and amount of applied electronic components. Nonfailure operating probability, failure intensity, and mean time to failure are basic qualitative characteristics of the reliability. The dangerous failures of electronic components can have critical and catastrophic consequences in the functionality of electronic equipment. The article deals with the procedure of the reliability calculation using various coefficients. Different mathematical models can be used for the same task of the reliability calculation. In order to solve the tasks, various methods can be used. All these facts may cause different results.Authors represent an approach to the coefficient method allowing to carry out the reliability calculation with higher precision and fidelity. The coefficient method is usable for comparing different ways for reliability calculation.

Reliability, coefficient method, time to failures.

Optimization of Automated Troop Command and Control System Operation Effectiveness in Terms of Reliability Criterion 53_1.pdf

A right selection between performance evaluation of effectiveness and functioning of automation solutions for automated troop command and control systems (hereinafter referred to as the C2 Systems) is the most important research aspect of its functioning effectiveness. C2 Systems, like any other large hardware and software complexes, have a range of technical features that provide meeting of requirements for these systems. Requirements in its turn are of regulatory nature specified in directive documents on automation of the Armed Forces of the Russian Federation. Reliability is one of the important features that have an impact on effectiveness of C2 Systems functioning. The article deals with a model of estimation of C2 Systems functioning when hardware and software failure. The estimation of C2 Systems effectiveness was demonstrated to refer to deterministic evaluation procedures and it can be represented as a multiplicative convolution of reliability performance. Two approaches to the estimation of effectiveness were unveiled and one of these approaches was chosen on a reasonable basis. The presented techniques allow changing the specific reliability performances of specific hardware and software complexes to a summarized system reliability value pertaining to a target function of the automated complex. The given approach to optimization of automated complexes in terms of cost-effectiveness factor allows to achieve the required performances at minimal costs.

Estimation of Hardware and Software Complex Readiness to Solve the Functional Tasks 52_3.pdf

N view of the increasing complexity of performed hardware and software functions of automated management systems, designers focus on the task to determinate the probability of hardware and software availability for a time intended for solving the functional objective. The article deals with the problems of reliability prediction and estimation of hardware and software readiness to solve the tasks. Authors offer a model of hardware and software presented as a functional part set. The things that improving the accuracy of estimation of the hardware and software readiness to solve functional tasks are justified. Authors present an operational availability factor chosen as a key characteristic of the hardware and software readiness to solve functional tasks. It is calculated on the basis of both current and statistical reliability indices of system components that make the functional parts. A prediction algorithm for the loading of central processor unit, RAM and external memory of the computer system is proposed. It uses an effect of exponential smoothing of statistical data before the period of prediction. The recommendations for operators and operating personnel on the practical application of methods proposed are presented in the article.

Reliability of Integrated Modular Avionics Reconfigurable Complexes 000_3.pdf

This paper briefly outlines the problems of calculations reliability for multiprocessor systems. The authors show disadvantages of the statistical calculations method for reconfigurable onboard equipment complexes. The preliminary system safety assessment procedure for the system developed is described. The helicopter onboard equipment complex, which is capable to function in cruise flight mode and in modes of landing and takeoff, was considered as an example. Respective hardware and functional graph was built. The graph takes into account functions criticality, data streams between them, and specific hardware features. Operating modes of the complex are also described. Evaluation of developed reconfiguration algorithms effectiveness was implemented with the use of Fault Tree Analysis (FTA) for the traditional federative architecture with double reservation and for the integrated modular avionics architecture that consists of a crate with the reserved commutation module. Respective fault trees were built and the numerical results of reliability evaluation were presented. In order to improve algorithms for performing better reliability, some recommendations are given. The authors also show the impossibility of implementing the reconfigurable architecture on the basis of the existing complexes with the dynamically reconstructive architecture. The architecture doesn't meet the requirements of complexes reliability and doesn’t comply with modern standards for airborne equipment development.

Software Maintenance and Operational Reliability Evaluation on the Basis of Network-centric Architecture 000_3.pdf

The article deals with the approach to the creation of network-centric control system of condition of products produced by the original equipment manufacturer and operated on the distant sites. The organization of interaction between the center (manufacturer) and the consumer that serves as the basis for the creation of network-centric structure is proposed. The ability of high-quality control of events on sites is shown by giving an example of remote control of failures and operating products troubles. This leads to the increasing of the product operation efficiency and gives an opportunity for developers to upgrade products faster due to the fast feedback. The structure, the architecture, the general algorithm of functioning, and the description of general mathematical model of software product maintenance and functioning reliability evaluation system are considered. The proposed solutions are implemented as a software package that was used for computing experiment and the confirmation of the discussed approach practical application.
