为解决疏通航道反水雷作战中的航道选择问题,根据水雷位置确定条件下的反水雷作战特点,运用多目标优化理论建立了与疏通时间最少和雷区航道最短等价的清除水雷数最少和航道倾角绝对值最小疏通航道优化模型。根据疏通航道反水雷作战实际,通过基于完全分层法的单目标模型解算流程、方法,得到优化参数,较好地满足了疏通航道反水雷作战需求。 相似文献

随着美国海军的作战重点从大洋转到濒海地区,水雷成为敌对力量“拒止”美军的一种重要武器。反水雷战也与反导、反潜作战相并列,成为美海军三种主要作战样式之一。美海军水雷战司令部已制定出2010年前水雷对抗(MCM)作战全面转型规划,其中包括主要武器平台系统的全面更新和水雷战组织编制的彻底调整。它将引发水雷对抗作战方式的变革,全面提升美海军的反水雷战能力。 相似文献

For the case where the lifetime at a stress level has a Weibull distribution, statistically optimal and practical accelerated life test plans are developed under the assumptions of intermittent inspection and Type-I censoring. For a statistically optimal plan the low stress level, the proportion of test units allocated, and the inspection times are determined such that the asymptotic variance of the maximum-likelihood estimator of a certain quantile at the use condition is minimized. Although the practical plan adopts the same design criterion, it involves three rather than two overstress levels and easily calculated inspection schemes. Despite some loss in efficiency the practical plan has several advantages over the statistically optimal one. For instance, the practical plan can provide means for checking the validity of the assumptions made, may reduce the danger of extrapolation, and is more convenient to determine and implement. Computational experiments are conducted to evaluate the relative efficiency of a practical plan to the corresponding statistically optimal plan. Guidelines for selecting an appropriate practical plan are also described with an example. 相似文献

The accelerated degradation test (ADT) is an efficient tool for assessing the lifetime information of highly reliable products. However, conducting an ADT is very expensive. Therefore, how to conduct a cost-constrained ADT plan is a great challenging issue for reliability analysts. By taking the experimental cost into consideration, this paper proposes a semi-analytical procedure to determine the total sample size, testing stress levels, the measurement frequencies, and the number of measurements (within a degradation path) globally under a class of exponential dispersion degradation models. The proposed method is also extended to determine the global planning of a three-level compromise plan. The advantage of the proposed method not only provides better design insights for conducting an ADT plan, but also provides an efficient algorithm to obtain a cost-constrained ADT plan, compared with conventional optimal plans by grid search algorithms. 相似文献
