In order to improve the reliability of electronic products and reduce the probability of failure of spare parts, this paper proposes a method of using alternation to detect electronic products regularly. Firstly, we regard the original element and the spare part as the reserve system and consider the fault of the elements caused by human error at the same time. Secondly, we take the Alternate interval...
A maintenance interval optimization problem with uncertain parameters of life time distribution is discussed in this paper. Based on the classical age replacement model, a new maintenance interval optimization model with uncertain parameters is established. The model is a nonlinear programming problem. The objective function is to minimize the maximum cost rate increased relative to the possible minimum...
An improved method of motor detection based on symbolic time series analysis is proposed, and the method adaptively partition off the region which has the most symbols in the symbolic series into two new regions, which enhances the sensitive degree of symbols to the signal. Except that the fuzzy relative entropy is introduced in the paper to improve the reliability of the diagnosis results. Laboratory...
An improved method of motor fault detection based on symbolic time series analysis is proposed, and the method adaptively partition off the region which has the most symbols in the symbolic series into two new regions. The method makes that the regions with more information are assigned more symbols relatively but those with sparse information are assigned fewer symbols, which enhances the sensitive...
