利用Stackelberg博弈(称为安全博弈)来分配有限的安全资源以对抗具有特定概率分布的不同攻击者类型已经引起了越来越多的兴趣。然而,这类真实的问题往往面临模糊的信息,如不精确,不可靠和不存在的回报,以及这些回报的模糊分配。为此,基于决策理论和证据理论,本文提出了一种新的框架,可以处理这些常见类型的歧义。更具体地说,本文部署了决策理论中现有规则的基本原则,作为一种在将模糊收益转换为点值收益的过程中,消除对模糊性的不同态度的方法。因此,我们的框架具有一些良好的特性:(i)它包含传统的安全游戏,没有模糊的回报,(ii)统一的误差幅度不会影响结果,(iii)完全无知的影响可以被最小化。此外,我们的框架通过使用九种不同的转换规则,在各种条件和约束下,对73,000个随机生成的游戏进行评估(迄今为止的第一次全面的经验评估)。评价揭示了每种转换规则的好处,并证实不同的规则可以模拟个体对歧义的不同态度。
There has been increasing interest in using Stackelberg game (known as a security game) to allocate limited security resources against different attacker types with a specific probability distribution. However, real problems of this kind often face ambiguous information, such as imprecise, unreliable and absent payoffs, and ambiguous assignments of these payoffs. To this end, based on decision theory and the Dempster–Shafer theory of evidence, this paper proposes a novel framework that can handle these common types of ambiguity. More specifically, this paper deploys the underlying principles of existing rules from decision theory, as a way to characterise different attitudes to ambiguity, during the transformation of ambiguous payoffs into point‐valued payoffs. Hence, our framework holds some good properties: (i) it subsumes traditional security games without ambiguous payoffs, (ii) a uniform margin of error will not affect the results and (iii) the influence of complete ignorance can be minimised. Also, our framework is evaluated by using nine different transformation rules, under various conditions and constraints, against 73,000 randomly generated games (a first comprehensive empirical evaluation to date). The evaluation reveals the benefits of each transformation rule and confirms that different rules can model individuals' different attitudes to ambiguity.
