Solution algorithms for the parallel replacement problem under economy of scale

We consider the parallel replacement problem in which machine investment costs exhibit economy of scale which is modeled through associating both fixed and variable costs with machine investment costs. Both finite- and infinite-horizon cases are investigated. Under the three assumptions made in the literature on the problem parameters, we show that the finite-horizon problem with time-varying parameters is equivalent to a shortest path problem and hence can be solved very efficiently, and give a very simple and fast algorithm for the infinite-horizon problem with time-invariant parameters. For the general finite-horizon problem without any assumption on the problem parameters, we formulate it as a zero-one integer program and propose an algorithm for solving it exactly based on Benders' decomposition. Computational results show that this solution algorithm is efficient, i.e., it is capable of solving large scale problems within a reasonable cpu time, and robust, i.e., the number of iterations needed to solve a problem does not increase quickly with the problem size. © 1998 John Wiley & Sons, Inc.

Na_2SO_4·10H_2O相变过程及其相变潜热的计算

利用CDR-34P差动热分析仪测试Na2SO4·10H2O相变前后的热效应,结合Na2SO4-H2O体系的二元相图,分析相变前后热效应的来源及体系相态、组分的变化;提出无机水合盐相变潜热除来源结晶水脱离外还包括固相物质溶解、溶液浓度梯度变化的热效应的观点;根据上述相变过程计算Na2SO4·10H2O相变潜热,误差仅为2%.     

The human consequences of foreign military intervention

The empirical international conflict literature has given much recent attention to interstate armed force’s impact on human well-being. While empirical research has advanced our understanding of the phenomenon considerably, we argue that one conclusion that many studies have reached is preliminary. Some recent research contends that only full-scale war, and not force short of war, has a discernable impact on human welfare or physical quality of life (PQOL). We develop theory on one type of force short of war, large-scale foreign military intervention (FMI), and its potential effects on PQOL. Using interrupted time series and panel corrected standard error methodologies, we find that from 1960 to 2005 large-scale FMI had a statistically and substantively significant impact on the PQOL of populations in 106 developing countries. The specific effect that this type of armed force has depended in large part on the regime type of the target country.     

改进警卫形式的挑战与对策

改进警卫形式,落实“内紧外松”警卫原则,是保持我们党同人民群众血肉联系的需要,是践行“三个代表”重要思想和贯彻既保证安全又方便群众方针的需要,是改革开放和经济建设的需要。警卫工作要想得到人民群众的理解和支持,首先要从改进警卫形式入手,克服草木皆兵、岗哨林立、警笛长鸣的人海战术;坚持内(宾)外(宾)有别的原则,树立群众观念,尽可能做到不扰民或少扰民,采取措施,在保证安全的前提下,维护人民群众正常的生活、工作秩序。     

缩小国民收入分配差距和深化分配公平探析

国民收入分配公平是发展社会主义市场经济,建设和谐社会、小康社会的内在要求,而不合理的户籍制度、市场竞争体制以及监管制度缺陷,导致了贫富差距日益扩大。要实现共同富裕的基本目标,就必须加大改革力度,促进社会公平竞争,不断缩小收入分配差距,让全体人民共享发展成果。     

消防法中责令停止执业的法律依据

《消防法》规定的责令停止执业是对有法定消防行政违法行为的单位予以暂停相应资质、资格的一种处罚措施。其处罚主体为国家认证认可监督管理委员会以及地方质检部门;其处罚过程应适用听证程序,并确认、核实情节是否严重;其处罚实施应附有合理期限,同时需要采取相应保障措施。
