Reliability engineering - Wikipedia

The reliability estimation of engineered components is fundamental for many optimization policies in a production process. The main goal of this paper is to study how machine learning models can fit this reliability estimation function in comparison with traditional approaches e. We use a supervised machine learning approach to predict this reliability in 19 industrial components obtained from real industries. Particularly, four diverse machine learning approaches are implemented: artificial neural networks, support vector machines, random forest, and soft computing methods. We evaluate if there is one approach that outperforms the others when predicting the reliability of all the components, analyze if machine learning models improve their performance in the presence of censored data, and finally, understand the performance impact when the number of available inputs changes. Our experimental results show the high ability of machine learning to predict the component reliability and particularly, random forest, which generally obtains high accuracy and the best results for all the cases.

Getting Good Failure Rate Data - Part 1: Safety Design Optimization - Failure Rate

Reliability engineering is a sub-discipline of systems engineering that emphasizes dependability in the lifecycle management of a product. Reliability, describes the ability of a system or component to function under stated conditions for a specified period of time. Availability, Testability , maintainability and maintenance are often defined as a part of "reliability engineering" in reliability programs.

Reliability engineering

The proposed approach for software reliability model selection seems perspective, Shooman. Software reliability modeling has moveling around since the early s with the pioneering works of Jelinski and Morandabooks, because it allows taking into consideration all pros and cons of reliability models and its possibility of application to the specific software.

High reliability safety factor levels also result from good engineering and from attention to detail, and almost never from only reactive failure management using reliability accounting and statistics!

Springer Handbook of Engineering Statistics pp Cite as. This chapter reviews fundamental ideas in reliability theory and inference. The first part of the chapter accounts for lifetime distributions that are used in engineering reliability analysis, including general properties of reliability distributions that pertain to lifetime for manufactured products. Certain distributions are formulated on the basis of simple physical properties, and other are more or less empirical. The first part of the chapter ends with a description of graphical and analytical methods to find appropriate lifetime distributions for a set of failure data.

Bringing together business and engineering to reliability analysis With manufactured products exploding in numbers and complexity, reliability studies play an increasingly critical role throughout a product's entire life cycle-from design to post-sale support. Reliability: Modeling, Prediction, and Optimization presents a remarkably broad framework for the analysis of the technical and commercial aspects of product reliability, integrating concepts and methodologies from such diverse areas as engineering, materials science, statistics, probability, operations research, and management. Written in plain language by two highly respected experts in the field, this practical work provides engineers, operations managers, and applied statisticians with both qualitative and quantitative tools for solving a variety of complex, real-world reliability problems. A wealth of examples and case studies accompanies:. Comprehensive coverage of assessment, prediction, and improvement at each stage of a product's life cycle.


Robust hazard log systems must be created that contain detailed information on why and how systems could or have failed. Charoensiriwath, J. Press, Oxford Google Scholar. Computer science Computer engineering Project ootimization Risk management Systems engineering.

Structural reliability or the reliability of structures is the application of reliability theory to the behavior of structures. The relevant Standards include:. Mathematically, this may be expressed as. As part of the requirements phase, the reliability engineer develops a test strategy with the customer.

The reliability program also includes a systematic root cause analysis that identifies the causal relationships involved in the failure such that effective corrective actions may be implemented.
