 The proposed reliability evaluation model considers the limited storage period and multi-stage degradation of self-recovery products. It incorporates the competitive failure concept, shock process, and self-recovery feature. Additionally, the difficulty of adding variables to a reliability model was addressed by using the Steelech's integral. The model's parameters were analyzed and its feasibility and theoretical reference values were demonstrated. This article was authored by Xinhang Wang, Baoyan Wang, Yichun Nio, and others.
