Researchers from the RUDN University in Russia have applied a new mathematical model called a Markovian arrival process to the breakdown of telecommunication systems and electronic equipment that handles client requests. "The results of this study can be used to analyze and optimize real stochastic systems in which servers are subject to breakdowns and recovery," says RUDN's Valentina Klimenok. "These systems include any computer network."
The team created a model that accounts for the unreliability of the servicing devices and predicts the effect of breakdowns on the efficiency of the system. Earlier queuing system processes models yield large errors in the system performance evaluation, and scientists use the Markovian arrival process to model the requests and breakdowns occurrence. Performance indicators include the average number of requests, the distribution and the average number of busy devices, the distribution and the average number of devices under repair, and the likelihood of the incoming request to be immediately processed.
