Title: A repairable system subjected to hierarchical competing risks: Modeling and applications
Authors: Francisco Louzada - University of Sao Paulo (Brazil) [presenting]
Abstract: The proposal is to model for a single repairable system with a hierarchical structure under the assumption that the failures follow a nonhomogeneous Poisson process (which corresponds to minimal repair action) with a power-law intensity function. The properties of the new model are discussed in detail. The parameter estimators are obtained using the maximum likelihood method. A simulation study is conducted to show that our estimators are bias-free. The proposed modelling is illustrated on a dataset on a traction system of an in-pipe remotely controlled robotic unit.
