新战略下的驻日美军调整

伊拉克战争,美国可说是弊大于利。正因为如此,针对这场战争中的利弊得失,美军开始通过新世纪“全球战略构想”,对军队有计划地进行战略调整,特别是对海外军力部署。并在2004年美军“军力转型”概念中,加上了“调整全球军力态势”的条文。该条文按美国防部的总体意见,不仅是对美国海外驻军人数实施大幅裁员,更重要的是对全球战略实施转型,将军力侧重点从欧洲向亚洲转移。下面,我们就美国驻日部队与基地,在这次“军力转型”中实施改组与调整的全面情况进行透视。

D-S 证据理论应用中的一种图解方法

D-S证据理论是对概率论的进一步扩充,在多传感器数据融合中,有着广泛的应用.当利用D-S合成公式进行融合时,由于需计算的项数较多且不易直接判定具体该有哪些项,容易造成漏项或错项,引起计算错误.提出了一种直观、简单的图解法,可使需计算的项一目了然.     

D-S证据理论应用中的一种验证方法

D-S证据理论是一种比概率论确定性弱的不确定性理论,它能将"不知道"和"不确定"两个认知学上的主要概念区别开来,在多传感器数据融合中具有广泛的应用前景.D-S证据理论在实际应用中却存在一个困难,当目标的个数较多时,需要计算的项数太多,容易造成漏项,引起计算错误.提出了一种确定计算项数的算法,作为验证计算结果的必要条件,并通过图解的方法找出需要计算的项.     

军事设施建设项目环境影响评价有关问题分析及建议

根据《中国人民解放军环境保护条例》,军事设施建设项目应进行环境影响评价。由于军事项目建设内容高度机密、国防需要迫切、建设时间紧迫等,再加上一些从事军事设施项目建设的管理人员对环境影响评价的理解还存在某些偏差,使许多军事设施建设项目未进行环境影响评价,影响了我军的环境保护工作。简要介绍了军事设施的范围及军事设施建设项目的环境影响评价概况,结合军事设施建设项目环境影响评价中出现的一些问题,提出了进行军事设施建设项目环境影响评价工作的几点建议。     

Stage life testing

In progressive censoring, items are removed at certain times during the life test. Commonly, it is assumed that the removed items are used for further testing. In order to take into account information about these additional testing in inferential procedures, we propose a two‐step model of stage life testing with one fixed stage‐change time which incorporates information about both the removed items (further tested under different conditions) and those remaining in the current life test. We show that some marginal distributions in our model correspond either to progressive censoring with a fixed censoring time or to a simple‐step stress model. Furthermore, assuming a cumulative exposure model, we establish exact inferential results for the distribution parameters when the lifetimes are exponentially distributed. An extension to Weibull distributed lifetimes is also discussed.

Values for optimum reject allowances

Industrial situations exist where it is necessary to estimate the optimum number of parts to start through a manufacturing process in order to obtain a given number of completed good items. The solution to this problem is not straightforward when the expected number of rejects from the process is a random variable and when there are alternative penalties associated with producing too many or too few items. This paper discusses various aspects of this problem as well as some of the proposed solutions to it. In addition, tables of optimum reject allowances based on a comprehensive model are presented.     

Multiproduct batching and scheduling with buffered rework: The case of a car paint shop

We study a problem of scheduling products on the same facility, which is motivated by a car paint shop. Items of the same product are identical. Operations on the items are performed sequentially in batches, where each batch is a set of operations on the same product. Some of the produced items are of the required good quality and some items can be defective. Defectiveness of an item is determined by a given simulated function of its product, its preceding product, and the position of its operation in the batch. Defective items are kept in a buffer of a limited capacity, and they are then remanufactured at the same facility. A minimum waiting time exists for any defective item before its remanufacturing can commence. Each product has a sequence independent setup time which precedes its first operation or its operation following an operation of another product. A due date is given for each product such that all items of the same product have the same due date and the objective is to find a schedule which minimizes maximum lateness of product completion times with respect to their due dates. The problem is proved NP‐hard in the strong sense, and a heuristic Group Technology (GT) solution approach is suggested and analyzed. The results justify application of the GT approach to scheduling real car paint shops with buffered rework. © 2014 Wiley Periodicals, Inc. Naval Research Logistics 61: 458–471, 2014

Determining optimum reject allowances for deteriorating production systems

Since most manufacturing processes inevitably produce some defective items, it is common practice to produce a quantity larger than the actual order size. This excess is called a reject allowance. In this paper we consider production processes which undergo stochastic deterioration and demonstrate that under appropriate conditions a smallest optimum reject allowance exists and can be easily computed. We also investigate the optimality of periodic process inspections and show that in some cases one can do better by following an (r, R) inspection-processing policy.     

Multivariate dependent relevations with applications,and related topics

“Relevation” is the name given by Krakowski to the distribution of failure time of a replacement from an aging stock. The present authors have extended this concept to include (i) hierarchal replacement systems and (ii) dependence between lifetimes of original and replacement items. In this article, we present some further developments, including first steps toward a synthesis of (i) and (ii).
