Stochastic bounds for microprocessor systems availability
نویسندگان
چکیده
The computing of stochastic bounds has become an efficient technique to obtain performance predictions for computer systems by the mean of Markovian models. However, the quality of these bounds may be affected by several properties related not only to how to use the technique but also to the Markovian model itself. On the other hand, multiprocessor systems have become an efficient and widely used infrastructure to run several critical-life applications. In this paper, we describe how to calculate a stochastic bound for the multiprocessor system availability. We focus on the irreducibility of the model to show how it might influence the quality of bounds.

A stochastic version analysis of an M/G/1 retrial queue with Bernoulli schedule
In this work, we derive insensitive bounds for various performance measures of a single-server retrial queue with generally distributed inter-retrial times and Bernoulli schedule, under the special assumption that only the customer at the head of the orbit queue (i.e., a FCFS discipline governing the flow from the orbit to the server) is allowed to occupy the server. The method...
متن کاملStochastic bounds for a single server queue with general retrial times
We propose to use a mathematical method based on stochastic comparisons of Markov chains in order to derive performance indice bounds. The main goal of this paper is to investigate various monotonicity properties of a single server retrial queue with first-come-first-served (FCFS) orbit and general retrial times using the stochastic ordering techniques.
متن کاملBehavioral study of piston manufacturing plant through stochastic models
Piston plays a vital role in almost all types of vehicles. The present study discusses the behavioral study of a piston manufacturing plant. Manufacturing plants are complex repairable systems and therefore, it is difficult to evaluate the performance of a piston manufacturing plant using stochastic models. The stochastic model is an efficient performance evaluator for repairable systems. In...

متن کاملEfficiency Evaluation and Ranking DMUs in the Presence of Interval Data with Stochastic Bounds
On account of the existence of uncertainty, DEA occasionally faces the situation of imprecise data, especially when a set of DMUs include missing data, ordinal data, interval data, stochastic data, or fuzzy data. Therefore, how to evaluate the efficiency of a set of DMUs in interval environments is a problem worth studying. In this paper, we discussed the new method for evaluation and ranking i...
