The continuing resonance of the war as risk management perspective for understanding military interventions

In the late 1990s and 2000s, a slew of books and journal articles proposed that a nexus between risk management and warfare was emerging. This article argues that risk management ideas continue to shape recent campaigns against Libya, Islamic State, Syria, and the war on terror from Niger, Yemen to Somalia. It uses existing literature on risk and warfare to examine four key aspects of contemporary interventions. First, the article evaluates the overall strategic context as security concerns shift from terrorism toward renewed great power competition. Second, it re-assesses the risk calculus for military action through the language and grammar of risk invoked by politicians. Third and fourth, it addresses the continuing reliance on air power and the managerial ethos of military operations as important features of war as risk management.     

突发重大疫情风险管理支撑方法研究【专题】

突发重大疫情后，科学的风险管理方法可为有效规避和控制风险提供有力支撑。在突发重大疫情风险管理中，风险识别是基础，风险评估是核心，风险控制是目的。本文系统梳理与分析了风险管理中的常用方法，包括风险识别中的现场勘查法、事故树分析法、过程回溯法、专家认证法和案例分析法等5种方法，风险评估中的风险坐标图法、关键风险指标法、蒙特卡罗法、因果关系法和综合评价法等5种方法，以及风险控制决策中的成本收益决策法、决策树法和损失期望值决策法等3种方法，并对每种方法如何在此次由新型冠状病毒引发的突发重大疫情中实践应用进行了举例说明，可为今后在应对突发重大疫情时进行科学风险识别、有效风险评估和精准风险控制决策提供借鉴与参考。     

Governing risks in international security

Risks are omnipresent in contemporary international security. Despite a long tradition in security studies going at least back to Von Clausewitz, we consider that the topic of risk remains under-examined. This forum seeks to advance the research agenda on risk in security studies by showcasing work of scholars using advanced concepts of risk, based on insights from sociology, biology, psychology, and safety studies, to better understand the role of risk in international security. As a way of introduction, this short article sets out the main debates.

Disruption‐management strategies for short life‐cycle products

Supplier diversification, contingent sourcing, and demand switching (whereby a firm shifts customers to a different product if their preferred product is unavailable), are key building blocks of a disruption‐management strategy for firms that sell multiple products over a single season. In this article, we evaluate 12 possible disruption‐management strategies (combinations of the basic building‐block tactics) in the context of a two‐product newsvendor. We investigate the influence of nine attributes of the firm, its supplier(s), and its products on the firs preference for the various strategies. These attributes include supplier reliability, supplier failure correlation, payment responsibility in the event of a supply failure, product contribution margin, product substitutability, demand uncertainties and correlation, and the decision makes risk aversion. Our results show that contingent sourcing is preferred to supplier diversification as the supply risk (failure probability) increases, but diversification is preferred to contingent sourcing as the demand risk (demand uncertainty) increases. We find that demand switching is not effective at managing supply risk if the products are sourced from the same set of suppliers. Demand switching is effective at managing demand risk and so can be preferred to the other tactics if supply risk is low. Risk aversion makes contingent sourcing preferable over a wider set of supply and demand‐risk combinations. We also find a two‐tactic strategy provides almost the same benefit as a three‐tactic strategy for most reasonable supply and demand‐risk combinations. © 2009 Wiley Periodicals, Inc.

基于HHM的军事演习风险识别

军事演习风险对军事演习的安全顺利进行有很大的影响。有效控制演习风险,首先需要全面、系统地识别出军事演习中存在的风险因素。本文在给出军事演习风险定义的基础上,运用等级全息模型(hierarchical holographic modeling,HHM)~([1])的思想和方法建立HHM风险识别模型,对军事演习中存在的风险进行分析和识别,有助于提升军事演习风险识别的准确性和全面性,为军事演习风险的评估和控制打下坚实的基础,对军事演习的安全进行和军事训练水平的提升具有重要意义。
