1927-1949年国民政府军人抚恤观念之流变

军人抚恤是古今中外各国政府都必须面对的难题。经过长期的历史沿革，西方出现义务型抚恤观念，中国形成传统的恩赏型抚恤观念。南京国民政府建立后，军人抚恤观念在吸收西方现代抚恤因素的基础上，在受到多次冲击的前提下，也经历着鲜明的变迁过程，即由传统的恩赏型抚恤观念向现代义务型抚恤观念转变。     

金戈铁马战汶川——成都军区部队奋勇参加2008四川抗震救灾纪实

2008年5月12日14时28分,四川省汶川地区发生里氏8.0级特大地震,其范围之广、破坏之重、伤亡之多、救灾之难,在历史上是罕见的.重灾区面积达10万平方公里,涉及88个县(市、区),1204个乡镇,受灾人口超过4000万.     

刍议GJB 1371与GJB 3837的关系

在新装备的研制过程中,需要有效地开展保障性分析工作,同时会产生大量的信息,GJB 3837便是为有效地存储这些信息而制定的标准。为明确GJB 3837与保障性分析工作之间的对应关系,本文对GJB 1371与GJB 3837进行了简要介绍,并对二者之间的对应关系展开研究,以期为GJB 1371和GJB 3837的工程化应用奠定基础。

空袭兵器作战效能标准化问题研究

空袭兵器作战效能标准化将典型的空袭兵器的作战效能指数向选定的标准空袭兵器转化,其转化的结果用于防空兵力需求的计算。标准化过程主要包括标准空袭兵器的选择、作战效能指标体系的建立、指标权重的计算、性能指标参数的归一、效能指数的解算和标准化系数的换算六个步骤,运用加权算法、幂指数法和层次分析法建模计算,最终得出美台主要空袭兵器标准化效能数据。为空袭兵器作战效能的标准化提供了一种科学方法,从而便于实施防空作战资源需求分析和防空作战资源作战效能分析。     

Supply chain coordination with product line design and a revenue sharing scheme

Many manufacturers sell their products through retailers and share the revenue with those retailers. Given this phenomenon, we build a stylized model to investigate the role of revenue sharing schemes in supply chain coordination and product variety decisions. In our model, a monopolistic manufacturer serves two segments of consumers, which are distinguished by their willingness to pay for quality. In the scenario with exogenous revenue sharing ratios, when the potential gain from serving the low segment is substantial (e.g., the low‐segment consumers' willingness to pay is high enough or the low segment takes a large enough proportion of the market), the retailer is better off abandoning the revenue sharing scheme. Moreover, when the potential gain from serving the low (high) segment is substantial enough, the manufacturer finds it profitable to offer a single product. Furthermore, when revenue sharing ratios are endogenous, we divide our analysis into two cases, depending on the methods of cooperation. When revenue sharing ratios are negotiated at the very beginning, the decentralized supply chain causes further distortion. This suggests that the central premise of revenue sharing—the coordination of supply chains—may be undermined if supply chain parties meticulously bargain over it.     

Single‐machine scheduling with deadlines to minimize the total weighted late work

We consider scheduling a set of jobs with deadlines to minimize the total weighted late work on a single machine, where the late work of a job is the amount of processing of the job that is scheduled after its due date and before its deadline. This is the first study on scheduling with the late work criterion under the deadline restriction. In this paper, we show that (i) the problem is unary NP‐hard even if all the jobs have a unit weight, (ii) the problem is binary NP‐hard and admits a pseudo‐polynomial‐time algorithm and a fully polynomial‐time approximation scheme if all the jobs have a common due date, and (iii) some special cases of the problem are polynomially solvable.     

Pairwise model discrimination with applications in lifetime distributions and degradation processes

Reliability data obtained from life tests and degradation tests have been extensively used for purposes such as estimating product reliability and predicting warranty costs. When there is more than one candidate model, an important task is to discriminate between the models. In the literature, the model discrimination was often treated as a hypothesis test and a pairwise model discrimination procedure was carried out. Because the null distribution of the test statistic is unavailable in most cases, the large sample approximation and the bootstrap were frequently used to find the acceptance region of the test. Although these two methods are asymptotically accurate, their performance in terms of size and power is not satisfactory in small sample size. To enhance the small‐sample performance, we propose a new method to approximate the null distribution, which builds on the idea of generalized pivots. Conventionally, the generalized pivots were often used for interval estimation of a certain parameter or function of parameters in presence of nuisance parameters. In this study, we further extend the idea of generalized pivots to find the acceptance region of the model discrimination test. Through extensive simulations, we show that the proposed method performs better than the existing methods in discriminating between two lifetime distributions or two degradation models over a wide range of sample sizes. Two real examples are used to illustrate the proposed methods.
