| Abstract: | In view of complex electronic product reliability evaluation requirement with multi-performance degradation parameters, this paper proposes the reliability evaluation method based on wavelet entropy. Energy entropy is applied to calculate monitoring data of electronic product at each monitoring time, the reliability evaluation model is found using the calculation. Based on these, the detailed modeling steps and process are given. An example of applying this method is provided to vertify its effectiveness. |
