RELIABILITY ANALYSIS OF THE PRESSURE STEAM STERILIZER BASED ON MPGW DISTRIBUTION
ZHONG TianPing
Abstract：The hazard rate function with a bathtub-shaped curve is crucial in reliability engineering due to its ability to capture certain observed failure rate characteristics in real-world scenarios.This study introduces a novel MPGW(Modified Power Generalized Weibull)distribution capable of modeling hazard rate function exhibiting a bathtub shape.To evaluate the effectiveness of this model,the study conducted empirical research using a dataset of pressure steam sterilizer failures and compared its performance to 5 classical distribution models,the results indicated that this model exhibits significant advantages in terms of flexibility.
