For applications in large-scale distributed systems, it is becoming increasingly important to provide reliable scheduling by evaluating the reliability of resources. However, most existing reputation models used for reliability evaluation ignore the critical influence of task runtime. In addition, most previous work uses list heuristics to optimize the makespan and reliability of workflow appli...

Evaluation management systems, especially reciprocal peer evaluation systems, often have an assumption that more reviewers will produce better results. This tendency is labeled as the maxima strategy. This study examines the maxima strategy from both agreement and performance perspectives with the intent of examining the role of information in reliability and performance through an optimal numb...

System reliability is a fundamental requirement of Cyber-Physical System, i.e., a system featuring a tight combination of, and coordination between, the systems computational and physical elements. Cyber-physical system includes systems ranging from the critical infrastructure such as power grid and transportation system to the health and biomedical devices. An unreliable system often leads to ...

The reliability of software architectures is an important quality attribute to consider in the design of embedded software systems. Reliability is especially important in safety-critical systems where human health and safety is often at stake. Researchers have developed a number of models that can estimate the reliability of software systems at design time. These models use matrix operations of...

Applications of multi-state approach to the reliability evaluation of systems composed of independent components are considered. The main emphasis is on multi-state systems with degrading components because of the importance of such an approach in safety analysis, assessment and prediction, and analysing the effectiveness of operation processes of real technical systems. The results concerned w...

In this paper, a methodology is developed for reliability evaluation of electromechanical systems. The method is applicable in early design phase where there is only limited failure data available. When experimental failure data is scarce, generic failure data are searched from some related reliability data banks. In this method, Reliability Block Diagrams (RBD) is used for modeling the system ...

Improving System Reliability for Cyber-Physical Systems Leon Li Wu Cyber-physical systems (CPS) are systems featuring a tight combination of, and coordination between, the system’s computational and physical elements. Cyber-physical systems include systems ranging from critical infrastructure such as a power grid and transportation system to health and biomedical devices. System reliability, i....
