Opis:
Purpose: The increasing internationalization of markets make the creation of competitive advantages more difficult. Companies have to be faster, better and more economical than their competitors in order to survive. Reliable products offer the capability to develop competitive advantages. To achieve the reliability objectives, a systematic approach of reliability actions and supporting methods is necessary. The integration of reliability activities into companies with regard to company size and industry has not been quantitatively determined. Methodology: An international survey drawing upon literature was applied. Evaluations are based on descriptive and inductive statistics. Results: The empirical study reveals reasons for applying reliability management in industry, the extent of applied reliability methods and performed reliability actions to achieve reliability objectives and used reliability data. The results are differentiated according to company size and industry. Research implications: The results of this study are applicable to companies which have already dealt with reliability issues. Further studies should consider a cross-section status of reliability implementation in industry, as well as they should contain extended actions and methods of reliability. Value of paper: This research relates to the status of reliability management implementation in international industry. There are shown significant differences in industries and company size. The results show potentials in reliability management and can be used as benchmark.

Opis:
In this work, algorithms have been used to compare the reliability measure of helicopter structure critical points. Reliability index, Cornell’s reliability index and Hasofer-Lind’s reliability index have been calculated and analysed. Inputs to the algorithms, stress and strength were generated by using the Markov chain model based on actual flight records of helicopters. With this approach, results of methods for determining the reliability of critical points of a helicopter’s structure are properly founded.

Opis:
The paper is composed of two parts, in this part the multi-state homogeneous „m out of n” systems with reserve components are defined and their multi-state limit reliability functions are determined. In order to improve of the reliability of these systems the following methods are used: (i) a warm duplication of components, (ii) a cold duplication of components, (iii) a mixed duplication of components, (iv) improving the reliability of components by reducing their failure rate. Next, the effects of the systems’ reliability different improvements are compared.

Opis:
In the paper the basic notions of the ageing multistate systems reliability analysis are introduced. The multistate system reliability functions are defined and the mean values of the multistate system lifetimes in the reliability state subsets and in the particular reliability states are determined. The notion of the multistate system risk function and the moment of the system exceeding the critical reliability state are introduced. Further, in the developed reliability models, it is assumed that the system’s components have the multistate Weibull reliability functions with various parameters in their different reliability state subsets. Under this assumption, the proposed multistate system reliability models are applied in maritime transport to the reliability analysis of a bulk cargo transportation system and its reliability function, moreover other main characteristics are determined.

Opis:
Basic notions and agreements on reliability of three-dimensional nanosystems are introduced. The asymptotic approach to the three-dimensional nanosystem reliability investigation is presented and the nanosystem limit reliability function is defined. Auxiliary theorems on limit reliability functions of three-dimensional nanosystems composed of large number of independent nanocomponents are formulated and the classes of limit reliability functions for a homogeneous series and series-parallel nanosystems are fixed. A model of a three-dimensional series and series-parallel nanosystem with dependent nanocomponents is created and the class of limit reliability functions identical with the class in the previous case is fixed as well. The asymptotic approach to reliability evaluation of exemplary three-dimensonal series and series-parallel nanosystem with dependent nanocomponents is presented and its accuracy is discussed.

The paper is devoted to the comparison of two preventive replacement strategies anticipating failures of working elements: a cyclic one and one based on the age of the elements. Several classes of reliability functions are considered for which these strategies are shown to be more or less efficient.

The contribution deals with the issue of reliability theory and its principles used in the field of reliability engineering. The contribution focuses attention on the mutual linkage among risk engineering, quality engineering and reliability engineering, defines the term of reliability and clarifies reliability theory in general. The article gives an overview of the most frequently used indicators widely used in reliability theory such as probability density of failure occurring, mean and (high) failure rate, mean time between failures, mean time to failure, average life etc. and briefly defines selected reliability systems used in reliability analyses.

Series-“m out of n” systems and “m out of n”-series systems are defined and exemplary theorems on their limit reliability functions are presented and applied to the reliability evaluation of a piping transportation system and a rope elevator. Applications of the asymptotic approach in large series systems reliability improvement are also presented. The paper is completed by showing the possibility of applying the asymptotic approach to the reliability analysis of large systems placed in their variable operation processes. In this scope, the asymptotic approach to reliability evaluation for a port grain transportation system related to its operation process is performed.

Opis:
The paper is concerned with mathematical methods in asymptotic approach to systems reliability analysis. The complexity of the reliability investigation of large-scale systems is proposed to be approximately solved by assuming that the number of system components tends to infinity and finding the limit reliability function of the system. Some general results in the form of auxiliary theorems and examples of limit reliability functions of homogeneous and regular series-“m out of k” systems with exponential and Weibull reliability functions of system components are presented.

Opis:
The paper is concerned with the application of limit reliability functions to the reliability evaluation of large systems. Two-state large non-repaired systems composed of independent components are considered. The asymptotic approach to the system reliability investigation and the system limit reliability function are defined. Two-state homogeneous series, parallel and series-parallel systems are defined and their exact reliability functions are determined. The classes of limit reliability functions of these systems are presented. The results of the investigation concerned with domains of attraction for the limit reliability functions of the considered systems and the investigation concerned with the reliability of large hierarchical systems as well are discussed in the paper. The paper contains exemplary applications of the presented facts to the reliability evaluation of large technical systems.

Opis:
Context-aware processing is a part of intensively developed ubiquitous computing andmobile systems. Surrounding awareness is used to introduce new functions and solutions. Some categories of the context data are taken for security purposes in the context-aware security implementations.This kind of data has to meet some conditions since it is used for decision making about security mechanisms adaptation and configuration. One of these conditions is reliability. The paper presents vector approach to context data reliability assessment introducing mechanism which allows to assess reliability parameters for further usage in context aware security processing. The following aspects of the context data are taken into account: interface reliability, data quality, data source reliability and security level. Introducing reliability metric for context data may be beneficial to other mechanisms which utilize context data. The vector form of reliability may be even more flexible than the scalar value.
