Generating Pareto‐optimal boundary points in multiparty negotiations using constraint proposal method

In this paper a constraint proposal method is developed for computing Pareto‐optimal solutions in multiparty negotiations over continuous issues. Constraint proposal methods have been previously studied in a case where the decision set is unconstrained. Here we extend the method to situations with a constrained decision set. In the method the computation of the Pareto‐optimal solutions is decentralized so that the DMs do not have to know each others' value functions. During the procedure they have to indicate their optimal solutions on different sets of linear constraints. When the optimal solutions coincide, the common optimum is a candidate for a Pareto‐optimal point. The constraint proposal method can be used to generate either one Pareto‐optimal solution dominating the status quo solution or several Pareto‐optimal solutions. In latter case a distributive negotiation among the efficient points can be carried out afterwards. © 2001 John Wiley & Sons, Inc. Naval Research Logistics 48: 210–225, 2001     

考虑不确定性的保障设备设计方案决策方法

研究了模糊性对装备的保障设备设计方案优选决策过程中的影响,基于模糊数学理论和灰色关联分析提出了一个考虑不确定性的综合决策方法,并建立了数学模型。该模型通过计算各保障设备的备选设计方案到正、负理想设计方案的模糊灰色关联系数,来确定各备选方案的相对优势灰色关联度,依据相对灰色关联度对各备选方案进行优劣排序,实现决策。通过某型机载装备的外场测试设备方案的立项竞标决策案例,对模型进行了应用。     

增加射击密度,提高航次利用效率

本文根据统计学原理,提出了在每个航路上增加射击密度的设想,以达到既降低试验成本又保证试验结果的可靠性。文中对实现这种设想的可能性作了理论上的证明。这一设想突破了苏联靶场试验法的旧框框,可以使高炮综合体系统射击试验节省有效航次五分之四到三分之二,其效益是十分明显的。     

Eisenhower,science and the nuclear test Ban Debate 1953–56

Though historians debate whether Eisenhower seriously pursued a nuclear test ban agreement at the close of his presidency, few have closely examined his consideration of the issue during his first term in office. Publicly, his administration ridiculed Democratic presidential candidate Adlai E. Stevenson's highly publicized test ban proposal in 1956. In fact, Eisenhower's private inclination to ban testing antedated Stevenson's campaign proposal by two years. A review of the administration's techniques of countering Stevenson's test ban proposal reveals the use of heated rhetoric, clever deception, and outright lies to manipulate public understanding of the test issue and to conceal the depth of Eisenhower's own sincere desire to limit, or even cease, tests.     

THE MIDDLE EAST WMD-FREE ZONE CONFERENCE

This article reviews the origins and evolution of the Middle East weapons of mass destruction-free zone (WMDFZ) concept and the proposal for a 2012 conference on the subject, and explores new challenges and opportunities for regional arms control in the current regional environment. It suggests that new models may be necessary to revitalize regional arms control efforts. The establishment of a broad regional security forum could include, but should not be limited to, curtailing weapons of mass destruction through the zone approach. Even if the 2012 conference fails to materialize, or is limited to a one-time event, the proposal for such a conference has provided an important opportunity to rethink future options for a regional arms control and security process.     

Controlling Novichoks after Salisbury: revising the Chemical Weapons Convention schedules

ABSTRACT

Novichok agents are a class of nerve agents developed by the Soviet Union during the Cold War. In light of the use of a Novichok agent in Salisbury in March 2018, two sets of proposals to amend Schedule 1 of the 1993 Chemical Weapons Convention (CWC) have been put forth, one jointly by the United States, Canada, and the Netherlands, and the other by Russia. Both sets of proposals will be discussed and voted upon at the next Conference of States Parties of the Organisation for the Prohibition of Chemical Weapons (OPCW) in November 2019. If either set of proposals is approved, it will be the first time that the list of chemicals subject to verification under the CWC will have been modified. This viewpoint will discuss these proposals, and argue that, if adopted, the joint proposal and the portions of the Russian proposal upon which consensus can be reached would significantly strengthen the CWC by considerably expanding the coverage of its Schedule 1 and bringing Novichok agents firmly within the CWC’s verification system. We also argue that, since the OPCW Technical Secretariat did not deem the fifth group of chemicals proposed by Russia to meet the criteria for inclusion in Schedule 1, Russia should withdraw this part of its proposal from consideration. The proposals have also served an important purpose in clarifying the identity of the chemical agent used in the Salisbury incident, squarely placing it within one of the two families of Novichok agents described by the Russian chemical-weapons scientist and whistleblower Vil Mirzayanov. If either proposal is approved in November, it will be important to conduct a thorough assessment of key precursors for the synthesis of Novichok agents and assess the need to amend CWC schedules and national and multinational export-control lists accordingly.

倡真反伪 弃虚返实——《儒林外史》主题新探

关于《儒林外史》的主题,至今众说纷纭。解决这个问题的核心是从这部讽刺小说中找出作者的价值判断。书中所讽刺的各种人物,归于一点,在于学问或人格的“伪妄”。而小说的价值判断标准,即为“真儒”的人格学问之“真”和他们“礼乐兵农”的济世方案之“实”。所以,人才观念上的倡真反伪和社会主张上的弃虚返实,即为小说的基本主题。     

基于高精度景象匹配的SAR平台定位方法研究

为了提高SAR平台定位精度,本文提出了一种基于景象匹配的SAR平台定位的方法。该方法利用成像中间时刻SAR平台与SAR图像中心线上物点共线的特性,先在图像中心线上均匀选取若干点作为匹配点,并与光学基准图进行高精度景象匹配获取它们的物点坐标;然后根据这些物点坐标估计出图像中心线在当地水平面投影的直线方程;最后利用直线信息和斜距高度信息计算SAR平台在水平面上的投影点位置,进而计算得到成像中间时刻SAR平台的空间位置。为了进一步提高匹配精度,分别提出了对正侧视和斜视SAR图像匹配区域进行几何粗校正的方法。本文还分析了不同误差因素对平台定位精度的影响,并给出了精度估计公式。仿真和实际图像实验结果表明,本文方法正确可行,具有较高的定位精度,具备工程实用价值。
