基于博弈论的安全决策信息融合

安全信息融合的研究涉及多源信息的表示、内在联系和运动规律的研究。冗余和互补的多源信息在融合系统中不可避免地存在着相互竞争和协同作用,因而多源融合系统中的信息冲突与合作的分析成为信息融合理论研究中的核心与实质问题。博弈理论对冲突和合作局势分析与研究提供了一种定量工具,其研究成果成功地解释了多局中人在“交互决策”过程如何构造博弈的“均衡点”,以及“均衡点”所具有的各种特性。笔者在研究了博弈理论的基础上,以博弈论的观点和方法解决安全信息融合系统冲突信息环境下的融合系统决策问题,并建立了相应的模型并应用了融合算法。     

BOOK REVIEWS

This study focuses on the technology purchasing decisions of a mid-sized firm (500 employees) that increase the energy efficiency of its computing systems while meeting its business objectives. For example, if company growth requires implementation of a more robust and up-to-date customer tracking system and includes hiring 10 new employees, what course should be followed to ensure a reduction in energy consumption as well as the achievement of company business goals? Should the company purchase a couple of additional servers with limited capacity for growth or should the company replace 20 aging rack servers with six state-of-the-art servers for consolidation and the hosting of virtual machines? And should the company supply the new employees with new cathode ray tube (CRT) monitors or recycle some that have been in storage? There are several alternatives that the firm can use to achieve its goals. This paper evaluates four energy efficiency technologies with respect to their impact on the reduction in energy consumption as well as internal organisational processes and human aspects. A proposed research effort is expected to contribute to energy efficiency literature by capturing adoption decisions from a market – end-user – perspective, and the outcome of this study is proposed to give insights to energy efficiency programme managers into designing more accurate energy efficiency programmes.     

New tools in local energy planning: experimenting with scenarios,public participation and environmental assessment

This article presents a model for local energy planning and its application in a full-scale experiment in a Swedish municipality. The model is based on legal requirement, research findings and standards of good practice and includes a combination of analytical and procedural tools intended to support rational decision-making: external scenarios, a citizens’ panel, life cycle analysis and qualitative environmental assessment (EA). The application of the model indicates that the decision-support tools selected can give several new and valuable inputs to local energy planning, such as local knowledge and values through citizen dialogue and comprehensive EAs. However, the experiment also shows that there are several challenges involved in applying the tools, for example, it is difficult to get citizens and the industry to participate and that it is complicated to combine several different tools for decision-making into a single planning process. Moreover, the experiences from the application suggest that the model for local energy planning show great potential but needs to be improved before it can be used as a standard of good practice.     

Closing the knowledge-action gap in conservation with open science

The knowledge-action gap in conservation science and practice occurs when research outputs do not result in actions to protect or restore biodiversity. Among the diverse and complex reasons for this gap, three barriers are fundamental: knowledge is often unavailable to practitioners and challenging to interpret or difficult to use or both. Problems of availability, interpretability, and useability are solvable with open science practices. We considered the benefits and challenges of three open science practices for use by conservation scientists and practitioners. First, open access publishing makes the scientific literature available to all. Second, open materials (detailed methods, data, code, and software) increase the transparency and use of research findings. Third, open education resources allow conservation scientists and practitioners to acquire the skills needed to use research outputs. The long-term adoption of open science practices would help researchers and practitioners achieve conservation goals more quickly and efficiently and reduce inequities in information sharing. However, short-term costs for individual researchers (insufficient institutional incentives to engage in open science and knowledge mobilization) remain a challenge. We caution against a passive approach to sharing that simply involves making information available. We advocate a proactive stance toward transparency, communication, collaboration, and capacity building that involves seeking out and engaging with potential users to maximize the environmental and societal impact of conservation science.     

2013年台风决策气象服务浅析

2013年在西北太平洋和南海海域共有31个编号热带气旋生成,其中有9个在中国登陆.2013年台风活动具有生成个数多、登陆个数偏多,登陆强度强、登陆集中在华南,灾害损失重等特点.分析2013年登陆我国的台风气象决策服务情况,发现“天兔”提前5天即给出了明确的登陆预测信息,但与实际情况差异较大;“潭美”、“天兔”和“菲特”台风气象服务效果较好,均提前2天给出了准确的登陆点和强度预报.其中“菲特”作为1949年以来在10月份登陆我国大陆的最强台风,“菲特”台风气象服务开展迅速有力,决策服务启动早,预警信息发布频次高,部门应急联动及时,各级政府防范有力,其造成的人员伤亡及社会影响远轻于以往同类台风.     

可持续发展目标下的清洁发展机制项目评价

清洁发展机制（CDM）是《京都议定书》规定的发达国家和发展中国家之间项目级的合作机制，CDM项目的目标之一是促进发展中国家的可持续发展。在京都议定书最终生效的背景下．CDM项目的开发与能力建设成为热点。本文基于多目标决革理论。讨论CDM促进可持续发展与否的评价方法。以国际最新的研究为基础。作者构建了CDM项目可持续评价的指标化体系。建立了评价过程。并将其应用刭具体的案例——内蒙古辉腾锡勒风电CDM项目的评价中。研究可以为中国的CDM潜在项目的选择、比较和批准等实践活动提供定量的方法和思路。这对于中国成为CDM国际合作中的重要参与者以及促进中国的可持续发展都具有重要的意义。     

Evaluation of Urban Sustainability in Specific Sectors in Latvia

In Latvia, the concept of sustainability is only slowly gaining recognition. An analysis of Development Plans prepared by the four largest cities of Latvia indicates that sustainability is presented as one of the guiding principles. However, a comparison of Development Plan policies against the urban sustainability issues reveals a great deal of ambiguity and contradiction.At the municipal level, planners and politicians lack indicators to gauge whether the long-term goals of Development Plans and the principles of sustainable development are being achieved. As a consequence, the broad public is deprived of the opportunity to assess for itself the process of development in relation to Development Plan policies, thus limiting accountability in development decision-making. Relevant statistical data collected on a regular basis are required to create sustainability indicators reflecting sustainability issues, to supplement and replace existing statistical compilations pertaining almost exclusively to economic growth and consumption. Development and utilisation of sustainability indicators can be an effective instrument for promoting the values of sustainable development amongst politicians, planners and the broad public and for enhancing accountability in decision-making.
