The invention discloses an accelerated degradation modeling evaluation method based on an uncertain process, and belongs to the technical field of accelerated testing. The method specifically comprises the following steps that: aiming at certain batch of products to firstly collect and preprocess the testing data of a tested sample; then, importing the uncertain process into accelerated degradation modeling, modeling each accelerated degradation process, meanwhile, constructing an accelerated model to represent a relationship between accelerated stress and a degradation model, and then, carrying out uncertain quantization on the accumulation credibility of each sample ADT (Accelerated Degradation Testing) data under each accelerated stress; utilizing the accumulation credibility, and combining with a least square principle to estimate an unknown parameter in an accelerated model degradation process; and finally, according to first-passage distribution, giving the evaluation results of the assurance degree of reliability and the assurance reliability life of the product of the batch. By use of the method, the problem that a high risk is brought to the production of a product due to cognition uncertainty since a traditional evaluation method can not quantify small samples is avoided.
