研究成果概要
1) We construct a model for the delayed reporting of non-fatal faults which are accumulated before being reported in groups, which is applicable to warranty claim analysis. We extend this model to account for multiple fault types, planned preventative maintenance and customer rush.


We have submitted a manuscript for presentation in an invited session at the 10th International Conference on Mathematical Methods in Reliability in Grenoble, France, on 3-6 July 2017. We also presented our paper at 2016 Joint NZSA+ORSNZ Conference (27-30 November 2016) and the Joint Workshop – New Development of Stochastic Models (15 October 2016). Our paper on this model was awarded a Best Paper award at the Asia-Pacific Workshop on Advanced Reliability and Maintenance Modelling (Seoul, August 2016).


2) We present a general approach to inference in multicomponent systems where the system is viewed as being made up of Independent Overlapping Subsystems (IOS).


We submitted a paper on this project to IEEE Transactions on Reliability in February 2016 and submitted a revision of the paper in December 2016.


3) We present a unified model for multi-component systems with dependent failures and imperfect repairs.


A paper on this project was finalised and submitted to “Stochastic Operations Research in Business and Industry,” World Scientific, for inclusion as a book chapter in December 2016.
