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.

Tytuł:: Vector Approach to Context Data Reliability
Autorzy:: Tunia, M. A.
Powiązania:: https://bibliotekanauki.pl/articles/106311.pdf
Data publikacji:: 2014
Wydawca:: Uniwersytet Marii Curie-Skłodowskiej. Wydawnictwo Uniwersytetu Marii Curie-Skłodowskiej
Tematy:: data reliability

security level
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.

Wydawca:: Uniwersytet Morski w Gdyni. Polskie Towarzystwo Bezpieczeństwa i Niezawodności
Tematy:: reliability
critical points
reliability index
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 present work deals with the exploration of a new model proposed for the reliability analysis of industrial production systems. This proposed model is mainly based on the tangent hyperbolic function, where the survival function is determined and used in the lifetime distribution modeling taking into account of estimation the parameters of the proposed function. On the other side, tests validation is performed using the real data of a gas turbine installation. The obtained results allow the modeling of damage effects, hence the prediction of the performance of the examined gas turbine using the proposed model gives good results in terms of validity.

Tematy:: reliability

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.

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.

Tematy:: reliability

multistate system
large system
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:: A purpose of the article is discussing the method of technical systems reliability modelling. The most important methods used for constructing realist models of the physical world, i.e. the method of the experimental modelling and the method of the probabilistic modelling, were presented. The particular attention was focussed on the method of the probabilistic modelling allowing for taking into account uncertainty in functioning of systems. An example of using the proposed method to the modelling of the reliability of the air-traffic-control-system was quoted.

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.
