Non-parallel storage life test evaluation method based on accelerating factor feasible region selection

The invention discloses a non-parallel storage life test evaluation method based on accelerating factor feasible region selection. The method comprises the following steps: I, calculating an accelerating factor and comprehensive failure time; II, discussing an accelerating factor feasible region; III, performing parameter selection by using an optimal linear unbiased estimation method; IV, calculating the point estimation and interval estimation of logarithm reliable life. Specific to the phenomenon of missing of storage data in non-parallel storage product life estimation, storage data and test data are integrated, and calculation is performed by making full use of data on the basis that the service life follows Weibull distribution, so that the accuracy of life model parameter estimation is ensured, an algorithm has low requirement on the initial value of a parameter, the algorithm iteration is rapid and simple, and the operability is high.
