TLDR
A general simulation/analytic approach for jointly assessing the reliability and performance of a communication/computer network is proposed and can derive sensitivity information about network performance with respect to various parameters-the first step for an effective network optimization algorithm.Abstract:
A general simulation/analytic approach for jointly assessing the reliability and performance of a communication/computer network is proposed. The advantages of this approach are the following: (a) it allows consideration of a variety of performance measures, (b) it allows consideration of a general structure of network components failure distribution, (c) it reduces complexity of the model and related calculations, (d) it is relatively simple to implement, and (e) it can derive sensitivity information about network performance with respect to various parameters-the first step for an effective network optimization algorithm. The method is illustrated in a number of examples using network connectivity and weighted network bandwidth as a measure of performance. >read more

Reliability engineering: Old problems and new challenges
TL;DR: The first recorded usage of the word reliability dates back to the 1800s, albeit referred to a person and not a technical system as discussed by the authors, and since then, the concept of reliability has become a pervasive attribute worth of both qualitative and quantitative connotations.

A Particle Swarm Optimization Approach Based on Monte Carlo Simulation for Solving the Complex Network Reliability Problem
TL;DR: This is the first attempt to use PSO combined with MCS to solve complex network reliability problems without requiring knowledge of the reliability function in advance, and the proposed MCS-PSO can minimize cost under reliability constraints.

From complexity science to reliability efficiency: a new way of looking at complex network systems and critical infrastructures
TL;DR: The modern view of Complexity Science is embraced to introduce innovative measures of the reliability performance of a network system, termed reliability efficiencies, intended to measure the global and local robustness of the network to faults of its components.

On Evaluating the Performability of Degradable Computing Systems
TL;DR: A hierarchical modeling scheme is used to formulate the capability function and capability is used, in turn, to evaluate performability, and techniques are illustrated for a specific application: the performability evaluation of an aircraft computer in the environment of an air transport mission.

Closed-Form Solutions of Performability
TL;DR: This paper considers the modeling of a degradable buffer/multiprocessor system whose performance Y is the (normalized) average throughput rate realized during a bounded interval of time and shows that a closed-form solution of performability can indeed be obtained.
