Abstract Details

2019, Master of Science (MS), Ohio University, Industrial and Systems Engineering (Engineering and Technology).
Nonhomogeneous Poisson process models have been widely used to describe the failure frequency for repairable systems subject to minimum repairs. This thesis proposes new failure intensity functions to model the failure frequency for a repairable artillery system with an S-shaped failure intensity curve. It is motivated by a recent study on the performance of artillery exercise. The maximum likelihood estimation method is applied in the thesis to estimate the model parameters. Also, the confidence intervals for the targeted maximum-likelihood estimators including the expected numbers of failures are provided. Finally, the results derived from the new-proposed models and the existing model are illustrated for comparison. The study is based on the actual data from ROK Army artillery repair data reported by a recent study in the literature.
