Software reliability prediction is a statistical method to put in place a timely software development practice useful for objective assessment of bidders. The current study suggests one research method that enables reliability assessment on such previous projects by studying user satisfaction and the amount of delay in delivery time. If incorporated into the existing acquisition process, the re...

Probabilistic design, such as reliability-based design and robust design, offers tools for making reliable decisions with the consideration of uncertainty associated with design variables/parameters and simulation models. Since a probabilistic optimization often involves a double-loop procedure for the overall optimization and iterative probabilistic assessment, the computational demand is extr...

Introduction: Objective Structured Clinical Examination (OSCE) is one of the most appropriate methods for assessment of clinical skills.Validity and reliability assurance is a mandatory factor for any assessment tool. In Shiraz University of Medical Sciences, medical students’ clinical competences are evaluated by a pre-internship OSCE. This study is designed to examine the validity and reliabi...

To avoid the difficulties in human error data collection or elicitation and make Human Reliability Analysis (HRA) more generic, a new HRA approach is proposed based on meta-operation identification and task complexity measurement. In this approach, a task is decomposed into metaoperations which is defined as the smallest identifiable operation or activity exhibited in the performance of a task....

The human unreliability is the main cause of industrial accidents. In the petrochemical field, about 90% of accidents are due to human errors. Over the years, several models of Human Reliability Analysis have been developed. The major limitation of these models is due to their static nature. Thus, the present research aims to propose a new innovative approach to evaluate the variability of the ...

CONTEXT All assessment data, like other scientific experimental data, must be reproducible in order to be meaningfully interpreted. PURPOSE The purpose of this paper is to discuss applications of reliability to the most common assessment methods in medical education. Typical methods of estimating reliability are discussed intuitively and non-mathematically. SUMMARY Reliability refers to the...

Due to the critical challenges and complexity of modern software systems developed over the last decade, there has arisen an ever increasing attention to look for products with high reliability at reasonable costs. Software development process moves toward component-based design, and architecture based approach in software reliability modeling is widely used. However, in lots of models for soft...

Wind turbines can be considered as structures that are in between civil engineering structures and machines since they consist of structural components and many electrical and machine components together with a control system. Further, a wind turbine is not a one-of-a-kind structure but manufactured in series production based on many component tests, some prototype tests and zeroseries wind tur...

This thesis studies the reliability of telecommunications equipment, its components, and the systems made using those components. Special attention is paid to creating stronger links between the reliability analyses performed at different hierarchy levels. The thesis starts with a temperature derating study. It is found out that the generic handbook based procedures may not always be very attra...
