Abstract

This paper proposes a framework for identifying the most significant risks during rotor assembly process, based on Analytic Hierarchy Process (AHP) and Bayesian Belief Network (BBN). The assembly of rotors is a very critical process and risk assessment method is crucial to ensure operation safety. The application of the method revealed that the most significant risks are related to software malfunction, program failure, system function failure and poor integration of hardware and software. The paper proposes responses to these risks aiming at preventing the occurrence of failure. The analysis put forward here may be an invaluable source for maintenance professionals, safety engineers and decision makers in companies, in the sense that it augments their information and helps to identify critical risks in the rotor assembly process. The identification and prioritisation of risk factor makes it easier to allocate resources to prevent rotor failure and improve product quality and ensure organisation sustainability.
