Cyber-weapons are software and software, at least intuitively, is non-physical. Several authors have noted that this potentially renders problematic the application of normative frameworks like UN Charter Article 2(4) to cyber-weapons. If Article 2(4) only proscribes the use of physical force, and if cyber-weapons are non-physical, then cyber-weapons fall outside the purview of Article 2(4). This article explores the physicality of software, examining Stuxnet in particular. First, I show that with a few relatively uncontroversial metaphysical claims we can secure the conclusion that Stuxnet is physical. In particular, there exist instances of Stuxnet that are both located in space and causally efficacious, and this is very strong evidence for their being physical. Second, I argue that the question of physicality is actually irrelevant for the moral evaluation of an attack like Stuxnet because of its undeniably physical effects. Finally, I argue that some features of Stuxnet should make us optimistic about the prospects for discrimination and proportionality in cyberwarfare.  相似文献

The extended economic lot scheduling problem (EELSP) is concerned with scheduling the production of a set of items in a single facility to minimize the long-run average holding, backlogging, and setup costs. Given an efficient cyclic production schedule for the EELSP, called the target schedule, we consider the problem of how to schedule production after a single schedule disruption. We propose a base stock policy, characterized by a base stock vector, that prescribes producing an item until its inventory level reaches the peak inventory of the target schedule corresponding to the item's position in the production sequence. We show that the base stock policy is always successful in recovering the target schedule. Moreover, the base stock policy recovers the target schedule at minimal excess over average cost whenever the backorder costs are proportional to the processing times. This condition holds, for example, when the value of the items is proportional to their processing times, and a common inventory carrying cost and a common service level is used for all the items. Alternatively, the proportionality condition holds if the inventory manager is willing to select the service levels from a certain set that is large enough to guarantee any minimal level of service, and then uses the imputed values for the backorder costs. When the proportionality condition holds we provide a closed-form expression for the total relevant excess over average cost of recovering the target schedule. We assess the performance of the base stock policy when the proportionality condition does not hold through a numerical study, and suggest some heuristic uses of the base stock policy. © 1994 John Wiley & Sons, Inc.  相似文献

Cyber operations are relatively a new phenomenon of the last two decades.During that period,they have increased in number,complexity,and agility,while their design and development have been processes well kept under secrecy.As a consequence,limited data(sets)regarding these incidents are available.Although various academic and practitioner public communities addressed some of the key points and dilemmas that surround cyber operations(such as attack,target identification and selection,and collateral damage),still methodologies and models are needed in order to plan,execute,and assess them in a responsibly and legally compliant way.Based on these facts,it is the aim of this article to propose a model that i))estimates and classifies the effects of cyber operations,and ii)assesses proportionality in order to support targeting decisions in cyber operations.In order to do that,a multi-layered fuzzy model was designed and implemented by analysing real and virtual realistic cyber operations combined with interviews and focus groups with technical-military experts.The proposed model was evaluated on two cyber operations use cases in a focus group with four technical-military experts.Both the design and the results of the evaluation are revealed in this article.  相似文献

If material failures follow a Poisson distribution, then the expected number of failures is exactly proportional to flight hours. However, this article demonstrates that proportionality will not be revealed by simple correlation or regression analysis between monthly flight hours and the number of monthly failures. To test for proportionality, one must instead test the underlying hypothesis that the data follow a Poisson distribution. This article presents three simple tests that may be used for this purpose. The Poisson distribution requires that the mean and variance of the number of failures be equal. This article suggests several alternative models that may be used for samples in which the variance exceeds the mean. First, the mean of the Poisson distribution may itself be randomly distributed across the observational units according to a gamma distribution. If so, the number of failures will have a negative binomial distribution. Second, the mean of the Poisson distribution may depend systematically upon a set of observable explanatory variables. In this case, the Poisson regression model is appropriate. Finally, the mean of the Poisson distribution may contain both a systematic component that depends upon observable variables and a random component. This situation yields a generalized Poisson regression model.  相似文献

消防监督检查原则对于规范和制约消防监督检查权的行使具有重要作用。然而,目前消防法律对消防监督检查的原则并没有明确规定,这对于监督和制约消防监督检查权的行使,保护被检查对象的合法权益十分不利。对消防监督检查必须遵循的原则进行了探讨,提出了五项原则,即依法检查原则、比例原则、服务性原则、相对人参与原则和救济原则。  相似文献

It is commonly accepted that recourse to war is justifiable only as a last resort. If a situation can be resolved by less harmful means, then war is unjust. It is also commonly accepted that violent actions in war should be necessary and proportionate. Violent actions in war are unjust if the end towards which those actions are means can be achieved by less harmful means. In this article, I argue that satisfaction of the last resort criterion depends in part upon the likelihood of success of non-violent alternatives to war, and that the actual and potential effectiveness of non-violent resistance means that the last resort criterion of the jus ad bellum and the proportionality criterion of the jus in bello are harder to satisfy than is often presumed.  相似文献
