“…For instance, Yang proposed an improved bootstrap method based on gray theory, 27 James introduced several new variants of the wild cluster bootstrap, 28 Shao improved bootstrap by using the virtual augmented sample method to analyze reliability, 29 and Chang proposed a parametric bootstrap approach to improve the Durbin‐Watson test, which is inaccurate for small samples 30 . The bootstrap method has been widely applied in various fields, such as medicine, 31 biology, 32 mechanical engineering, 33 aerospace, 34 and so forth. Moreover, the bootstrap method is also commonly used to study fatigue life and reliability of sample parts.…”

Fatigue testing is a crucial technique for assessing the fatigue performance of materials and components. However, the testing process often involves numerous uncertainties, such as variations in part roughness and size, and the collected data typically constitutes small samples. This paper proposes an improved bootstrap method with cycle of uncertainty to address the limitations of traditional bootstrap methods in estimating uncertainties in small sample sizes. The proposed method was applied to estimate the effect of surface roughness and common normal size on fatigue tests, resulting in improved estimation accuracy. The research contributes to the development of improved methods for fatigue life estimation, which has practical implications for mechanical component design and optimization.

“…This method uses a unified damage report template with combined target specific information and compared the historical database to realize automatic damage effect evaluation. [10] proposed the error spectrum to evaluate the weapon system accuracy and [11] presented a method to assess a fragmentation weapon's effectiveness, which provides the basis for the weapon systems selection problem. [12] investigated the local damage and fragments of unreinforced masonry walls under different close-in explosions, and the blast load time histories from close-in detonations.…”

Target Damage Effectiveness Evaluation (TDEE) is not only an important guarantee for commanders to make decision-making follow-up actions, effectively control the combat process and optimize the fire attack scheme to the greatest extent, but also an important way to detect target information search, target research and target selection. Damage probability calculation is one of the most important performance index of the TDEE. In this paper, a new damage probability calculation method for submunition to target is proposed based on intersection volume algorithm. Firstly, the intersection between submunition and a target is studied, and the calculation model of target damage probability is given; secondly, a damage probability calculation method was proposed based on intersection volume algorithm. Finally, the correctness of the proposed method is verified by the numerical examples.

“…However, ES has several drawbacks, which attracts lots of researches to focus on the improvement of the ES. To solve the computation problem, Liu et al presented the Mellin transform to compute the ES analytically [6], then, we proposed two algorithms to calculate the ES based on the power means error and the Gaussian mixture model, respectively [7], [12], [13]. Furthermore, to solve the dynamic evaluation problem, Mao et al introduced a dynamic error spectrum (DES) to transform the ES into a single point at a time instant [8].…”

Comprehensive measures for the estimation performance evaluation (EPE) has become increasingly prominent. This paper proposed a new radar chart evaluation method to measure the estimation performance. Firstly, the new radar chart index, which is composed of several popular incomprehensive measures, are presented, and the method of the weight of the each index is calculated based on vector ranking method. Secondly, the new comprehensive measures for the EPE is designed according to the fan area and the fan arc length. Finally, two cases study are provided to verify the effectiveness of this method.
