Estimation of the Parameters of the Wiener Degradation Process for the Reliability Analysis Using the Amoebaalgorithm

Abstract

Deterioration models have provided accuracy in estimating reliability, including theWiener process-based degradation model, researchers have introduced several methods for estimating the parameters of the degradation process. In this research, the researcher proposed the Amoeba algorithm to estimate the parameters of the Wiener degradation process and it was compared with the method of maximum likelihood estimations, this was applied through Monte Carlo simulation, the results were that the Amoeba method is best based on the MSE comparison criterion, then the reliability was estimated based on the inverse Gaussian distribution according to the characteristics of the Wiener process.
