چکیده
Software fault-tolerance techniques have been widely used in computing systems to achieve high level of quality. Rejuvenation, a modern software fault-tolerance technique, has attracted a large number of researchers in software engineering area. Evaluating the effectiveness and feasibility of this technique becomes extremely important in selecting, comparing and applying it in actual software systems. The study of importantquality-attributes is the scientific basis for assessing the performance of software fault-tolerance techniques. This paper presents availability, reliability, safety evaluation of rejuvenation systems. Derived mathematical relations between failure probabilities and modeling parameters enable us to gain a great deal of quantitative results.

Availability analysis of mechanical systems with condition-based maintenance using semi-Markov and evaluation of optimal condition monitoring interval
Maintenance helps to extend equipment life by improving its condition and avoiding catastrophic failures. Appropriate model or mechanism is, thus, needed to quantify system availability vis-a-vis a given maintenance strategy, which will assist in decision-making for optimal utilization of maintenance resources. This paper deals with semi-Markov process (SMP) modeling for steady state availabili...
متن کاملDesign and Practical Implementation of a New Markov Model Predictive Controller for Variable Communication Packet Loss in Network Control Systems
The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...

متن کاملMarkovian Delay Prediction-Based Control of Networked Systems
A new Markov-based method for real time prediction of network transmission time delays is introduced. The method considers a Multi-Layer Perceptron (MLP) neural model for the transmission network, where the number of neurons in the input layer is minimized so that the required calculations are reduced and the method can be implemented in the real-time. For this purpose, the Markov process order...
