“… Redundancy: It is the foresight of the system to consider extra resources and alternatives to encounter emergency states when some facilities or human resources are unavailable (Frangopol & Curley, 1987). Fault-tolerant: It means if some components or operators of system confront a disorder, system can operate continuously in a proper manner (Domínguez-García et al, 2008).…”

Construction sites are accident-prone locations and therefore safety management plays an important role in these workplaces. This study presents an adaptive algorithm for performance assessment of project management with respect to resilience engineering and job security in a large construction site. The required data are collected using questionnaires in a large construction site. The presented algorithm is composed of radial basis function (RBF), artificial neural networks multi-layer perceptron (ANN-MLP), and statistical tests. The results indicate that preparedness, fault-tolerance, and flexibility are the most effective factors on overall efficiency. Moreover, job security and resilience engineering have similar statistical impacts on overall system efficiency. The results are verified and validated by the proposed algorithm.2018 Growing Science

“…Draper Laboratory's Performance and Reliability Analysis via Dynamic Modeling (PARADyM) is an analysis suite to facilitate fault-tolerant design and operational concepts, and is the latest evolution of several decades of development in integrated system reliability estimation [3][4][5][6]. The latest approach utilizes MATLAB® and Simulink® to model each electro-mechanical component of the system with its respective dynamics or functional behavior, failure modes, and dependencies.…”

“…Also, cascading failures are captured in the integrated model -truncation only refers to the limit of concurrent random failures evaluated by the Markov model. For a greater discussion on PARADyM, the reader is referred to the research by Dominguez-Garcia that led to its development [5][6][7], or to contact the authors for more information (eventually to be published in a full-length paper).…”

This paper discusses a method used for the systematic improvement of NASA's Lunar Surface Systems avionics architectures in the area of reliability and faulttolerance. This approach utilizes an integrated system model to determine the effects of component failure on the system's ability to provide critical functions. A Markov model of the potential degraded system modes is created to characterize the probability of these degraded modes, and the system model is run for each Markov state to determine its status (operational or system loss). The probabilistic results from the Markov model are first produced from state transition rates based on NASA data for heritage failure rate data of similar components. An additional set of probabilistic results are created from a representative set of failure rates developed for this study, for a variety of component quality grades (space-rated, mil-spec, ruggedized, and commercial). The results show that careful application of redundancy and selected component improvement should result in Lunar Surface Systems architectures that exhibit an appropriate degree of faulttolerance, reliability, performance, and affordability. 12

“…The approach suggested here is not widely used. The main reason is that existing classical reliability quantification methods are not sufficient [1,2]. This is due to the dynamic characteristic of a control system.…”
