Statistics Seminars: Statistical issues with the reliability of telecommunications products

Presented by Simon Wilson, Trinity College Dublin

21 December 2007 10:00 in TBA

Telecommunications products, such as make up a wireless network, are characterised by the requirement for very high availability, extensive production testing and the use of multiple back-up of critical components. In this talk I will discuss two statistical issues that arise in the testing of telecoms products and in the analysis and prediction of their reliability. The first is the use Bayesian modelling through Bayesian networks to model the complicated structure and dependencies between components and software in these systems; these models are used to produce predictions for product reliablity while the product is in development. The second is an application to production testing, which is a very expensive process for these products. The use of Bayesian inference techniques to estimate test properties has helped to optimise this process.
