Exponential reliability function
WebThe following model is established: (1) R c ( t c) = e − λ c t c, where R c is torpedo loading reliability, t c is torpedo loading time, and λ c is torpedo load failure rate. In this work, failure rate and reliability are mainly used to characterize the torpedo loading reliability. 2.1. WebMar 3, 2024 · The paper proposes a methodology of reliability testing as applied to vehicles used in military transport systems. After estimating the value of the reliability function using the Kaplan–Meier estimator, reliability models were developed and analysed. The neural model, which achieved the value of the correlation coefficient R exceeding 0.99, …
