Markov Analysis – A Brief Introduction

What is Markov Analysis?

Markov analysis is a method of analysis that can be applied to both repairable and non-repairable types of system. The basic output of a Markov analysis is the average time spent by the system in each of its distinct states before the system moves (or makes a transition) into some other distinct state. For example, such a transition or change of state will occur if the system suffers a component failure or if a repair has been carried out. A distinct change in the state of the system will have taken place in both of these cases.

The output from the Markov analysis enables a complete description of the system to be obtained in terms of its reliability, availability and resource utilisation (e.g. use of maintenance teams, spares holdings, buffers, etc). Also different system designs can be explored by comparing their reliability and availability performances as well as the effect of small tweaks to a given design under consideration. Results produced by a Markov analysis can then be used within a cost-benefit analysis to help identify the optimal design choice. Continue reading

10 Tips for Event Tree Analysis

Wikipedia describes Event tree analysis (ETA) as “a forward, bottom up, logical modeling technique for both success and failure that explores responses through a single initiating event and lays a path for assessing probabilities of the outcomes and overall system analysis”. However, like many techniques, its benefits rely on it being used properly. Continue reading

A Comparison of Classical and Bayesian Statistics

It is surprising to most people that there could be anything remotely controversial about statistical analysis. Nevertheless appearances can be deceptive, and a fundamental disagreement exists at the very heart of the subject between so-called Classical (also known as Frequentist) and Bayesian statisticians. Continue reading
