某高校新区周边区域火灾危险及对策探析

降低高校新区周边区域的火灾风险是提高高校新区消防安全水平的重要方面。在分析高校新区周边区域火灾特点的基础上,总结了在消防安全方面存在的问题,如村镇消防规划滞后、基础设施匮乏、消防安全管理体系不健全、管理方法单一等。从完善村镇规划、加强基础设施建设、健全消防安全管理体系、深化消防安全管理创新等方面提出了高校新区周边区域消防安全管理的对策。     

基于模糊综合评价法的公众聚集场所火灾风险评估

利用模糊综合评价方法,对某公众聚集场所进行火灾风险评估,建立了风险评价的指标体系并确立了各指标的权重值,对建筑起火的可能性、火灾损失的严重程度以及火灾综合风险进行了分析,最终从降低火灾发生可能性以及降低危害后果严重程度两方面,提出了该公众聚集场所的火灾风险控制措施,从而为此类场所的火灾隐患定性和消防监督管理提供依据。

Can Smart Defense work? A suggested approach to increasing risk- and burden-sharing within NATO

“Smart Defense” is NATO's new approach to risk- and burden-sharing, which has been a chronic problem within the alliance since the 1950s. Numerous solutions have been proposed, but initiatives resulting in more equitable burden-sharing have never been fully implemented. There are two driving forces influencing a county's willingness to support such initiatives – the economic theory of alliances and the risks posed by the implementation of capability sharing. The authors examine each of these and propose that rather than aiming for group consensus on the production of capabilities, NATO should focus on interoperability through support functions. This approach provides the most likely solution for connecting the forces, doctrine, procedures, standards and other factors of joint capability production such that country leaders find the risks of doing so to be politically and militarily acceptable.     

An enterprise portfolio approach for defence capability planning

Capability-based planning (CBP) is considered by many defence organisations to be the best practice for enterprise-level planning, analysis and management. This approach, loosely based around investment portfolio theory, is premised on balancing the cost, benefit and risk of capability options across the defence enterprise. However a number of authors have recently noted limitations of its current applications. The authors propose a more general, insurance-based approach, which can support the evolutionary improvement of the current CBP approach. This approach is implemented as hedging-based planning and aims to better reflect the enterprise nature of defence organisations, capturing both force structure and force generation aspects of military systems.     

基于FMECA的信息系统软件失效安全风险评估与预测

随着大量软件产品应用于信息系统,不可避免地增大了软件失效对系统安全的影响概率。本文以某信息系统文电收发的处理过程为例,引入FMECA法,对其文电收发处理过程中由软件造成的风险进行分析,同时分析了引起风险常见的失效模式,并引入Markov模型对软件失效造成系统严重危害的风险进行预测,通过Markov模型与FMECA法结合能够迅速定位软件失效的原因,减少因软件失效造成的系统损失。     

A location‐inventory model with lateral transshipments

We study an infinite horizon periodic stochastic inventory system consisting of retail outlets and customers located on a homogenous line segment. In each period, the total demand, generated by the customers on the line, is normally distributed. To better match supply and demand, we incorporate lateral transshipments. We propose a compact model in which the strategic decisions—the number and locations of retail outlets—are determined simultaneously with the operational decisions—the inventory replenishment and transshipment quantities. We find the optimal balance between the risk‐pooling considerations, which drive down the optimal number of retail outlets, and lateral transshipments, which drive up the optimal number of retail outlets. We also explore the sensitivity of the optimal number of retail outlets to various problem parameters. This article presents a novel way of integrating lateral transshipments in the context of an inventory‐location model. © 2011 Wiley Periodicals, Inc. Naval Research Logistics, 2011     

Specification vagueness and supply quality risk

Specifying quality requirement is integral to any sourcing relationship, but vague and ambiguous specifications can often be observed in practice, especially when a buyer is in the initial stage of sourcing a new product. In this research, we study a supplier's production incentives under vague or exact quality specifications. We prove that a vague specification may in fact motivate the supplier to increase its quantity provision, resulting in a higher delivery quality. Vague quality specification can therefore be advantageous for a buyer to screen potential suppliers with an initial test order, and then rely on the received quality level to set more concrete quality guidelines. There is a degree, though, to which vague quality specification can be effective, as too much vagueness may decrease the supplier's quantity provision and hence the expected delivery quality. © 2013 Wiley Periodicals, Inc.

Alternatives for defense in the Post‐Soviet World: A guide for economists to the U.S. debate

The defense establishments of all major powers are changing to reflect changes in the foundations of national security strategy and resource allocation. The authors believe economists should play an active role in formulating these changes and offer an orientation to the U.S. debate, presenting three major alternatives: the “Base Force” (Bush Administration), Mr. Aspin's Force “C,” and the “Low” Alternative (Prof. Kaufmann and Dr. Steinbruner). These alternatives are compared using first‐order measures of capabilities, budgets and risk. Budgetary estimates are based on newly‐developed analytical tools.     

CONFLICT RESOLUTION PROCESSES,UNCERTAINTY AND INVESTMENT DYNAMICS: EVIDENCE FOR THE BASQUE COUNTRY

The Junior Reserve Officers’ Training Corps is a high school program that combines classroom teaching with extracurricular activities. The program is located primarily in inner city schools and serves at‐risk students. Its goals are multidimensional and include military preparation and improving academic achievement. Using High School and Beyond data we find that the program’s effects depend on the timing and intensity of involvement. Test scores, graduation rates, and enlistments are higher for students who participate early in high school and for those who persist in the program. Conversely, we find few effects for students participating in the last two years of high school.
